Full textAbstract:
In the context of construction management, Social Infrastructure Projects (SIPs) have long been overlooked. However, SIPs are one of the main criteria for enhancing economic productivity. This paper analyses the results of a survey aiming to develop a framework for SIP success factors to enhance the likelihood of success in the provision of SIPs in Malaysia. The principal component analysis reduces a set of 41 project success factors to six dimensions based on the idea of the project life cycle, i.e., the preconstruction factor, the construction factor and post-construction factor, and three internal factors: the organizational factor, the information management factor, and the change management factor. Understanding these success factors could be crucial in managing SIPs, since it will allow project stakeholders to take precautionary steps to identify foreseeable problems and areas for improvement. This will increase the success rate of the project and could even help avoid problems completely.

Purpose: The risks and uncertainties of construction projects have the potential to cause damage to construction projects. Risk analysis and management are the main features of construction project management to effectively deal with uncertainties and unexpected events to achieve project success.
Design/methodology/approach: Some pertinent risk variables for each classification are six internal, four project risk factors, and four external. Researchers detected 14 external risk factor reasons, 36 internal risk factor causes, 16 project factor causes, and 36 external risk factor causes.
Findings: Researchers suggest project risk management through this study by implementing overall risk management. A properly executed project plan and identified risks as early as possible at a later stage turn into success. Managing risks does not mean avoiding them but identifying them correctly to determine all associated opportunities and hazards for project success.
Research limitations/implications: A good risk management approach anticipates the risk of building failure. It can happen in residential infrastructure projects. The first step in risk management is to study the risk factors for the loss of residential infrastructure buildings. Following an analysis, the project manager generates recommendations or plans for risk reduction in response to the primary risks in infrastructure projects.

Purpose: Aviation sector in Kenya facilitates both international and domestic trade, promotes tourism and foreign investment thus contributing to government revenue and employment opportunities. Therefore, improving airport infrastructure would help reduce travel time, improve connectivity. The high rates of project failure have become a major concern for stakeholders hence the need to identify key factors that promote project success or failure. This study seeks to assess the critical success factor influencing the performance of construction projects in Kenya.Methodology: The study adopted quantitative method to examine critical success factors for the performance of aviation construction projects in Kenya. Descriptive case study research design was adopted and self –administered questionnaires were used to collect quantitative for analysis. The variables of interest include timely financing project activities, competency of contractors, participation of stakeholders, and management skills. Descriptive analysis and inferential tests were conducted with the aid of IBM SPSS version 23 software.Results: The study found that timely financing, contractor competency, stakeholder participation, and management skills have positive and significant influence on the performance of aviation construction projects. Descriptive results suggest that tractors competency, timely financing, management skills, and stakeholders’ participation have a strong positive influence on project performance. The study has also established a significant contribution of contractor competency to the successful performance of aviation construction projects. It was also noted that participation of key stakeholders in projects identification, decision making, and resource mobilization can enhance the success of aviation construction projects. It was observed that these factors account for over 54.9% of changes in project performance.Unique contribution to theory, policy and practice: In light of these results, the study recommends industry players to put measures in place that would allow timely provisions of finance for all project activities. It is also important to source for competent and experienced contractors, engage key stakeholders in decision making about the project, and recruit a competent and skilled project manager. The study results have a significant contribution to practitioners in the aviation construction sector in Kenya. The study provides the practitioner with the most critical variables likely to influence the performance of aviation construction projects. It further acknowledges that external factors also influence the success of these projects. In light of this, the practitioners can institute contingency plans to mitigate the risks to ensure successful completion of their projects. To the academic, the current study has filled literature gap on critical success factors for aviation project performance. Given the upcoming mega project in aviation sector around the world, these factors provide the basis for future research in this area to ensure these projects are executed successfully within budget and schedule

The government often faces budget constraints and financial gaps between necessity and real allocation funds. It makes them must be more selective when prioritizing infrastructure development. Moreover, providing adequate transport infrastructure and sustainability is crucial for the government. Government must innovate by creating a conducive investment climate to encourage the participation of private and state-owned enterprises in infrastructure financing. Innovation financing through Private Funding and PPP schemes is directed to infrastructure with high economic and financial feasibility. PPP schemes in the air transportation sector particularly in Indonesia have not been successfully implemented until 2018. Therefore, the government has initiated several PPP projects as pilot projects to encourage PPP implementation in the Transportation Sector. One of them is Labuan Bajo International Airport. Labuan Bajo Airport is in West Manggarai Regency as a gateway to enter the Komodo Island area. Labuan Bajo airport is one key infrastructure that supports The Big 5 Super Priority Destinations of Indonesia by the Indonesia Ministry of Tourism and Creative Economy. This paper aims to examine critical success factors and interfere factors of the PPP pilot project for Labuan Bajo Airport. This paper uses an exploratory descriptive method to examine every factor that supports the success of the PPP implementation process in the air transportation sector based on qualitative data. The study will also explore the planning process through analysis of PPP Book documents from 2010-2020 (content analysis) to historically examine the process of proposing PPP project activities and examine the factors that support the success or delay the PPP pilot project within the Ministry of Transportation based on stakeholder approach. The planning and preparation stage plays a critical role in efforts to prepare comprehensive, reliable, and feasible projects. The feasible project can minimize project uncertainty and gain attract private sector investment.

Full textAbstract:
Road network is an essential infrastructure to enable efficient logistics and also forms the backbone of social and economic development. However, despite various efforts made by the government to develop the road network and ensure that these projects succeed in a timely manner, delays and cost overruns remain a problem for all road construction projects in many emerging economies. Namibia is no exception. So, it is important to identify critical success factors (CSFs) that need to be addressed for the timely delivery of road construction projects. Hence, adopting a qualitative approach, the aim of this study is to investigate critical success factors (CSFs) for timely delivery of road construction projects. The study recommends that the Roads Authority should engage capable companies, contractors, consultants, promote R&D, and do timely payment to eliminate project delays. The findings also propose that government introduces an alternative funding model for contractors who are awarded contracts.

Full textAbstract:
Public-private partnerships (PPPS) are increasingly being used in the construction of public services such as infrastructure in China. In the process of PPP project implementation, there are successes and failures, and the key factors of success are not completely clear. In order to identify the key factors for the success of PPP projects in the big data environment, PCA analysis is used to solve the problem of how to identify the key factors for the success of PPP projects in the big data environment. By studying the big data of PPP project and relevant literature at home and abroad, 32 potential key factors for success were constructed. The key success factors of PPP project were analyzed by questionnaire survey and principal component analysis. The results show that the 32 key factors for success can be summarized into five categories: political and economic environment, project development and operation management, government support and participation, government credit and commitment, strength of stakeholders, and factors of project bidding and procurement. Among the five factors, the key factors for the success of PPP projects are the continuous optimization of PPP policies, the rational project risk sharing mechanism, the guarantee and commitment of the government, the integrity and stability of government personnel, the satisfaction of public interests, and the complete financial analysis. This PCA method effectively solves the key factors for the success of PPP projects in the big data environment, ensures the smooth implementation of PPP projects, and promotes the long-term development of PPP projects.

The purpose of this study is to investigate the relationship between the critical success factors and the critical delays in the context of water infrastructure construction projects (WICPs) in the Abu Dhabi Emirate. In addition, the purpose of this paper is to develop a conceptual model to investigate the potential relationship. The literature concerning the critical success and delay factors and the related models that are available provide a starting point for developing the conceptual model. Based on the comprehensive and thorough literature review, all the dimensions of the variables are identified and discussed in detail.This study attempts to reduce the existing gap in the literature regarding the relationship between the critical success factors and critical delay. It forms a foundation upon which further local research can be conducted. In addition, it attempts to identify and point out the most critical success factors that will minimize the delay claims in water infrastructure construction projects (WICPs), as such delays would lead to some of the most difficult and controversial disputes to resolve. Internationally, it is expected that the findings of this research may help as an evidentiary reference data on which other and further similar comparative researches could be initiated and developed in different environments in terms of cultural, social, contractual, political, and environmental mediums.Finally, the conceptual framework was developed by identifying six (6) variables for project critical success namely Project Management Process (PMP), Project Manager Competency (PMC), Project Team Members’ Competency (PTC), Project Organizational Planning (POP), Project Resources’ Utilization (PRU) and Project Organizational Commitment (POC).

The earthquake on December 7, 2016 measuring 6.4 on the Richter Scale (SR), which hit the districts of Pidie, Pidie Jaya and Bireuen, has caused fatalities, damage to infrastructure and public facilities. In an effort to accelerate post-disaster rehabilitation and reconstruction, based on INPRES No. 5 of 2017, Aceh Provincial Building and Environmental Management Work Unit of the Ministry of Public Works and Public Housing, carried out the rebuilding of permanent schools using RISHA construction technology with a system of design and build contracts in Pidie Jaya District and Bireuen. This study aims to analyze the relationship and influence of design and build risk factors on the success of permanent school construction projects in Pidie Jaya and Bireuen Districts. This study uses qualitative and quantitative methods. Respondents were directed at 13 planning personnel, 25 implementing personnel, 21 construction management personnel and 13 owner staff. The independent variables in this study are the risk factors of design and build which consist of the owner management ability factor, procurement process, planning ability, implementation ability, project manager's ability, and project scope factors, while the dependent variable is the success of the project. The results of the study show that there is a low level of relationship between the factors of the project manager's ability, a sufficient level of relationships from the factors of implementation ability, procurement processes and project scope factors, a high level of relationship between planning ability factors and management owner's ability factors to project success. All design and build risk factors have a significant effect on project success, which is 68.8%. The dominant factor affecting project success is the project scope factor, with a regression coefficient of 0.162. In this case if the project scope factor is handled properly by all parties involved, then the success of the project will increase by 16.2%.

Full textAbstract:
Sustainability has captured extensive attention in Architecture, Engineering, and Construction (AEC) industry globally. However, how to achieve Infrastructure Sustainability (IS), one the critical dimensions measuring project success, although Project Management Practices (PMPs) in international contexts remain to be explored. Based on the empirical data collected from AEC practitioners with experiences in international infrastructure projects, this research develops two conceptual frameworks for PMPs and IS using principle components analysis (PCA) and confirmatory factor analysis (CFA). Four factors are identified for measuring PMPs with a composite reliability of 0.936—Culture, Strategy, Implementation, and Reflection—which are in analogy with the plan-do-check-action (PDCA) cycle ideology. Additionally, four metrics are also identified for IS with a composite reliability of 0.946—Project Economy, Organizational Integration, Social Utility, and Environmental Implication—which are established from project level, organizational level, to macro level, respectively. These findings contribute to the body of knowledge of construction project management and sustainable infrastructure development by demonstrating theoretical measurement frameworks for both PMPs and IS. Potentially, the outputs of this research will generate informative insights for practitioners to improve their PMPs in the process of pursuing IS in future AEC practices.

This study explores the success factors of concrete recycling in construction projects, using Malaysia as a case study. The objectives include (1) identifying the critical success factors for concrete recycling in construction projects, (2) comparing the critical success factors between large enterprises (LEs) and small–medium enterprises (SMEs), and (3) developing constructs that group the critical success factors. First, a list of success factors was identified through semi-structured interviews with fifteen construction industry professionals and a systematic literature review of journal articles. This list was then incorporated into a questionnaire and disseminated to industry professionals. Eighty-nine valid responses were collected and analyzed using mean score ranking, normalization, agreement analysis, and factor analysis techniques. The analyses showed ten critical success factors for concrete recycling. The critical success factors include the availability of uniform standards for concrete recycling, adequate awareness among project stakeholders on concrete recycling, appropriate construction waste management plans, government policies to support concrete recycling, good marketing strategy for concrete recycling, good communication among employees, applications for recycled concrete in sub-industries, provisions in work method statements on concrete recycling, positive legislation toward concrete recycling, and availability of concrete recycling infrastructure. However, the percentage of agreement between SMEs and LEs for the ten critical success factors was only 22%. In other words, there is no consensus on criticality across organizational sizes. Finally, the critical success factors can be categorized into two interrelated groups: external and internal. This study contributes to the literature by analyzing the necessary success factors for concrete recycling. The study findings allow researchers and practitioners to develop strategies to promote concrete recycling.

Design-build in construction industry becomes one of the project delivery method selected by owner. Light rail transit, mass rapid transit, and stadium renovation are examples of large infrastructure projects which are constructed under design-build approach to save time. In this approach, the design and construction phases are carried out simultaneously by contractor. One of the advantages for owners is that most risks are transferred to the contractors. This paper attempts to discuss contractors’ perspective related to risk factors in design-build project. The aim is to understand potential risk that can lead to an unsuccessful project. A questionnaire is developed that contains six factors with 20 sub-factors related to project risks. The questionnaire is distributed and responded by both state-owned and private enterprises contractors that involved in design-build project. Data are analysed using Significance Indexes method in order to obtain the relative significance of the risk sub-factors. The result shows five influenced sub-factors including project and program management issues that may cause risk to the contractor’s success under design-build project.

The present research was conducted with the aim of rethinking the criteria competency of airport construction project managers. The research methodology was applied in terms of purpose, and a combination of descriptive survey methods and content analysis in terms of implementation. The statistical population consisted of 550 experienced managers of construction industry in public and private sectors, including contractors, consulting engineers and their employers in Iran in the late decade to 2017. The sample size was 230 according to Morgan sampling table. The subjects were collected by stratified purposeful sampling method. The data gathering tools were the managers' desirability questionnaire with a reliability coefficient of 0.916, a project success rate with a reliability coefficient of 0.863 and an interview with the managers with an agreement coefficient of 0.899. The data were analyzed by SPSS and TOPSIS software using descriptive statistics of frequency, percentage, mean, standard deviation, and inferential statistics of exploitation, Factor analysis, Kolmogorov-Smirnov Test, and one-way ANOVA. The results of the research indicated that the airport construction is of great importance due to the necessity of developing the infrastructure and the territorial location. The criteria of competencies for managers in the airport construction industry are different from the past and attention to local and environmental criteria is among the recognized management criteria. The priority of localized thirteen competencies of the project managers was leadership, project financing, project cost management, problem solving, project governance, time management, strategic management, quality management, controlling and integrated management, managing legislation and regulations, networking and professional ethics. Moreover, the local factors of the project success in priority order were timely allocation of funds, appropriate financial support, integration, upstream project management, appropriate financing of financial needs, management integration, strategic stability, stakeholder commitment and accountability, review cost mismatch, completion of the project in due time, increase of knowledge level in the organization.

Purpose Successful implementation of infrastructure projects has been a controversial issue in recent years, particularly in developing countries. This study aims to propose a decision support system (DSS) for the evaluation and prediction of project success while considering sustainability criteria. Design/methodology/approach To predict sustainable success factor, the study first developed its sustainable success factors and sustainable success criteria. These then formed a decision table. A rough set theory (RST) was then implemented for rules generation. The decision table was used as the input for the rough set, which returned a set of rules as the output. The generated rulesets were then filtered in fuzzy inference system (FIS), before serving as the basis for the DSS. The developed prediction tool was tested and validated by applying data from a real infrastructure project. Findings The results show that the developed rough set fuzzy method has strong ability in evaluation and prediction of the project success. Hence, the efficacy of the DSS is greatly related to the rule-based system, which applies RST to generate the rules and the result of the FIS was found to be valid via running a case study. Originality/value Use of DSS for predicting the sustainable success of the construction projects is gaining progressive interest. Integration of RST and FIS has also been advocated by the seminal literature in terms of developing robust rulesets for impeccable prediction. However, there is no preceding study adopting this integration for predicting project success from the sustainability perspective. The developed system in this study can serve as a tool to assist the decision-makers to dynamically evaluate and predict the success of their own projects based on different sustainability criteria throughout the project life cycle.

The surging demand for logistics systems brought about by the vigorous development of e-commerce makes urban traffic more and more congested. The need for a sustainable transition in terms of urban transportation infrastructure also encourages the further innovation of logistics systems. The urban underground logistics system (ULS) emerges as a promising alternative for realizing efficient large-scale freight distribution in megacities. However, there are relatively few studies that have explored the factors that determine the uptake of ULSs in practice. This paper thus aims to identify the critical success factors of ULSs throughout project life cycle stages. Firstly, a desktop study and a study using the Delphi method were conducted to extract the critical success factors (CSFs) of ULS projects. Secondly, a questionnaire survey was conducted to collect data on the perceived significance of the selected success factors from ULS professionals. Thirdly, the intergroup comparison of the significance of CSFs and exploratory factory analysis were used to ascertain the critical factors and latent determinants influencing the development of ULS projects. In total, 36 CSFs in the four life cycle stages of ULS projects were finalized. The identified factors represent the seven latent determinants in developing a ULS project, namely, overall feasibility and acceptance of the ULS, prototype system, and business model, competence and resources for ULS construction and operation, station layout and intermodal transportation, government policies and incentives, long-term planning of the underground space and logistics network, and market investigation and forecasting. The research findings of the paper help guide practitioners and policy makers on decisions made during ULS planning and construction and provide a reference performance evaluation framework for ULS projects.

PurposeThe sustainable success of infrastructures is becoming a driving force for advancing urbanization globally. However, to achieve infrastructure sustainable success (ISS), how project management practices (PMPs) play their role remains unexplored in current literature. To this end, an empirical study on whether PMPs play significant impacts on the accomplishment of ISS was conducted.Design/methodology/approachThis research is based on an empirical survey of domestic and overseas infrastructure projects managed by Chinese companies. 162 data samples were collected and further analyzed deploying structural equation modeling (SEM) on the basis of goal-setting theory. PMP factors derived from the plan-do-check-act (PDCA) ideology, i.e. culture, strategy, implementation and reflection were hypothesized and validated to have direct and indirect relationships with ISS.FindingsThe results of this study indicate that both culture and reflection can directly drive the PMPs toward ISS. Furthermore, it is revealed that by affecting mediator factors of strategy, implementation and reflection, culture is found to present an indirect influence on ISS; by affecting mediator factors of implementation and reflection, Strategy is found to present an indirect influence on ISS and by affecting the mediator factor of reflection, implementation is found to present an indirect influence on ISS.Originality/valueThese findings contribute to the body of knowledge in measuring sustainability success of project management performances by clarifying critical relationships of how PMPs lead to ISS. Prospectively, the outputs of this research will generate informative insights for practitioners to improve their PMPs in the process of pursuing ISS in future infrastructure management practices.

The objective of this study is to investigate the significance impact of critical success factors on critical delays in the field of water infrastructure construction projects (WICPs) in the Abu Dhabi emirate in particular. Investigation was conducted utilizing quantitative approach by means of questionnaire survey to examine the understanding of professionals engaged in water infrastructure construction towards several critical success factors influencing critical delays. A total of 323 completed responses from owners, consultants and contractors representatives were gathered against 450 distributed questionnaires.The gathered questionnaires were analysed using an advanced multivariate statistical method of Partial Least Square Structural Equation Modelling (PLS-SEM). Data analysis was conducted in two major phases. The first phase involved a preliminary analysis of the data, to ensure that the data adequately meet the basic assumptions in using SEM. The second phase applied the two stages of SEM. The first stage included the establishment of measurement models for the latent constructs in the research. After confirming the uni-dimensionality, reliability and validity of the constructs in the first stage, the second stage developed to test the research hypotheses through developing the structural models. The results indicated that Project Management Process (PMP), Project Manager’s Competency (PMC), Project Team’s member Competency (PTC), Project Organizational Planning (POP), Project Resources’ Utilization (PRU) and Project Organizational Commitment (POC) had significant positive effects on Critical Delay Factor Evaluation (CDFS). From the results of moderation analysis revealed that Project Benchmark Characteristics (PBC) is positively moderate the effects of Project Management Process (PMP), Project Manager’s Competency (PMC) and Project Team’s member Competency (PTC) and Project Organizational Planning (POP) on Critical Delay Factor Evaluation (CDFS).

Project and program alliances have been an accepted form of project procurement for public infrastructure engineering projects in Australia and New Zealand (Australasia). Alliancing often provides best value and superior value for money when compared to traditional approaches such as Design and Construct, however considerable debate continues about its success and applicability. This paper reports on three studies of completed construction project alliance performance in 2008, 2010 and 2012. Consolidated findings are presented on 61 project alliances, data is analysed and emerging trends discussed. Recent government policy changes in Australia at Federal and State level have led to a decline in the number of project alliances, however, while the volume of alliance activity is declining it still represents billions of dollars of infrastructure construction work being undertaken. Results also revealed that communication and trust between the executive leadership and operational management teams was a major factor contributing to the functioning of the alliance. Furthermore, the research identifies several key factors that were necessary preconditions for successful alliances.Paper Type: Research article

Purpose Globally, inadequate resources, skills deficiency and poor infrastructure have necessitated public-private partnerships (PPPs) as investment initiative for public sector projects. The purpose of this paper is to evaluate the key constructs for improved stakeholder management (SM) success in curbing PPP projects’ failure in developing countries to fill the research gap. Pre-stakeholder identification (PSI); implementation, monitoring and feedback (IMF) factors impact on PPP projects’ success in Ghana were examined. Design/methodology/approach In total, 16 models were studied as part of literature review followed by a qualitative three-round Delphi survey for SM key factors and validated using a quantitative questionnaire survey. The findings were analysed using structural equation modelling and a model fit test. Findings PSI, IMF factors directly influence PPP SM success model hence are key constructs. Furthermore, stakeholder consideration, a clear statement of objectives, adopting design and build are variables established as influencing PPP projects failures. Stakeholder identification, engagement, communication and analysis are generic factors. Practical implications Project managers can achieve stakeholder satisfaction and improve PPP projects delivery by considering the innovative PPP SM model. Furthermore, considering the identified factors and variables in holistic models will enhance stakeholder involvement thereby curbing PPP projects failure. Social implications Reducing PPP projects’ failure will enhance socio-economic growth. Originality/value PSI; IMF factors have never been included in holistic PPP SM model. They are proposed to curb PPP projects’ failure.

Full textAbstract:
Construction projects are often delayed. Their budgets are being exceeded. This is partly because construction project models rarely take human factors into account. The article focuses on the repetitive multi-unit projects that are often found in construction practices. They are an excellent example of construction works for which the optimization of certain processes can bring measurable financial benefits. In particular, the focus was on improving the key investment success indicator, the total cost of a project. This article presents the use of learning and forgetting phenomenon to improve construction schedules. The authors proposed an innovative model of the construction phase and optimized the schedule using a proprietary calculation algorithm using the simulated annealing phenomenon. The method was verified by a series of experiments and showcased by a case study. The results show that the presented methods can improve the construction planning process and better reflect the current construction conditions. The findings may impact residential, infrastructure, industrial, and commercial construction branches.

Purpose Although scientific research community has shown considerable interest in identifying critical success factors (CSFs) for public-private partnership (PPP) projects, yet effort at assessing and compare CSFs within similar PPP infrastructure projects received scant attention. The purpose of this paper is to identify, assess, and compare the CSFs in PPP transport infrastructure projects. Design/methodology/approach The study adopted literature review and three PPP case studies including structured interviews and review of documentary reports in each case study. The outcome of literature review provided a total list of 26 identified success factors, which was used to design a case study protocol using failure mode and effect analysis (FMEA) technique. FMEA was conducted on each 26 identified success factor to assess their criticality in the three PPP case studies. Findings The results of FMEA revealed a total of ten CSFs in the concession of the road; four CSFs in the concession of the airport; and eight CSFs in the concession of the seaport. Also, the cross-case analysis showed the three prevalent CSFs, this includes government involvement by providing guarantees, political support, and project economic viability. Practical implications The study findings including lessons learnt in each case study would positively influence policy development towards PPP transport infrastructure projects and the manner in which partners (i.e. public and private sector) go about the development of PPP transport projects. Originality/value This research would help PPP stakeholders to focus their attention and priorities in managing the identified CSFs in achieving long-term success in PPP transport infrastructure projects implementation.

Although implementing quality assurance (QA) processes in construction play an important role in the South African economy has been acknowledged. However, constructions SMEs are faced with difficulties in improving rural road infrastructure and high-quality roads. Additionally, past research has failed to reach consensus on the construction process and socioeconomic settings in previously disadvantaged areas in South Africa, including the factors influencing negatively the performance of such factors. This research examines what factors facilitate or inhibit the success of construction SMEs and what actions can be taken to being distressed construction SMEs under control. The study adopted a quantitative research approach in which a three-section questionnaire was administered to 160 purposively chosen road- building experts in a South African construction SMEs. The questionnaire was structured into three parts, which sought the participants’ profile, identified the quality assurance practices (QAPs) incorporated in the construction SMEs’ road building programmes, and identified the factors that negatively influence the implementation of QA processes. Data was analysed using the Statistical Package for the Social Sciences (SPSS) version 22. Furthermore, to determine the reliability of the various constructs, mean scores, descriptive statistics and standard deviations were obtained. The empirical findings established eight QAPs that were reliable and valid for implementation processes that can control or minimise their causes of poor quality in projects undertaken by construction SMEs, level of skill acquisition; project planning and control techniques; project construction design; process implementation and process improvement; financial management; organisational structures; involvement of people; and quality standards and measurements. The eight factors attained high Cronbach Alpha values above the recommended 0.70 which indicates high internal consistencies among the sub-scales. Findings from this study should be useful to managers in similar environments may use the results of this study as either diagnostic tools or as a reference benchmark for strategic interventions in solving construction projects related problems. Furthermore, the researchers also recommend that these practices are for quality assurance in construction projects undertaken by SMEs in South Africa.

Abstract Integrating sustainable and complex financial performance models into Public-Private Partnership (PPP) project management is a challenging task due to the sheer number of inherent financial risks. Financial risk is a key impediment in the development of public infrastructure projects in Ghana. Studies on PPP projects in the country have concentrated on critical success factors and stakeholder management with little in-depth assessment of financial risks. This study develops and analyses the key financial risks of PPP infrastructure projects in Ghana. The research methodology is set as follows. First, the identification of twenty-eight financial risks in institutional and project reports, and peer-reviewed articles. Second, collection of primary data via surveys from 126 PPP experts (academics, risk managers and project managers). Third, the development and testing of a novel quantitative model on the criticality of financial risks of PPP projects. The findings show high interest charges, excessive operating expenses, and huge construction material costs as some of the critical financial risks that must be tackled immediately in the country. The outcomes of this study broaden the understanding of financial risks of PPP projects, and it sets the stage for further research.

Purpose – The purpose of this study is to use critical success factors (CSFs) to develop a process maturity and determine the current maturity levels of stakeholder organisations in public–private partnership (PPP) project implementation in Nigeria. The success of any PPP project is largely dependent on the country’s maturity on CSFs that made PPP projects successful. Thus, the identification of metrics and standards for measuring the maturity of stakeholder organisations on CSFs for PPP project implementation remains a challenge. Design/methodology/approach – The study adopted literature review and six PPP project case studies including interviews in each case study and expert forum. The outcome of a comprehensive literature review provides a total list of 14 CSFs that made PPP projects successful in Nigeria. These CSFs were used for capability maturity levels ' definition ranging from level 1 (Ad hoc) to level 5 (Optimising) in line with capability maturity model concept. Quantitative assessment was considered as a support tool for making an overall assessment of both the public and private organisations ' current capability maturity levels and for comparison approach. Findings – A capability enhancement framework for stakeholder organisations in PPP project was developed. This framework was used in assessing the current capability maturity levels of stakeholder organisations involved in PPP projects in Nigeria. Using this framework, it was found that public sector organisations were positioned between maturity level 1 and maturity level 2 (out of five maturity levels) on CSFs applicable to them. While, most private sector organisations were placed in maturity level 2 on CSFs associated with them. Practical implications – The results emanated from this study provided both the theoretical and practical implications. The theoretical implication provides new insights into the usefulness of CSFs in PPP projects and indicates that merely identifying possible CSFs for PPP projects is not sufficient. The practical implication shows that the framework developed in this study had provided the benchmark for the identification of methodical approach, and standard to process improvement in PPP infrastructure projects, which can be replicated in both the developed and developing countries. Thus, the framework could be used to benchmark future studies. Originality/value – The framework would provide a useful guide and roadmaps for improvement by indicating “what” needs to be done by stakeholder organisations involved in PPP projects in achieving higher capability maturity levels on identified CSFs for PPP projects in Nigeria and developing countries at large.

Full textAbstract:
The greatest challenges for construction infrastructure projects are those related to increasing problems of managing the time and cost in project implementation. For many years, new methods have been used to reduce the problems to do with separation of design from the implementation stage. An important point is that all projects tend to require integration; however, it has been observed that construction projects usually enjoy the benefits and capacities of updated methods and technologies later than other industries. One of these approaches, which have been growing in developed countries for some time, is using the Integrated Project Delivery (IPD) approach. Using such an approach has various benefits, but also would seem to pose significant challenges. To-date, it and has not still achieved success in terms of legal recognition and wider implementation. The aim of this study is to extract the benefits of the implementation of the IPD approach using an in-depth literature review. Then descriptive analysis is applied to identify the benefits of IPD. The benefits of applying this approach for key construction project stakeholders are classified using pattern analysis. This study has offered a framework in order to present available generic and specific benefits to each project stakeholder, and it provides the required motivation for project owners to use and implement it in their future projects. Moreover, they should understand the important factors that lead to IPD adoption. They can use this information to develop a contractual framework to make it more effective.

The article outlines the areas of improvement of existing approaches and analytical technologies for identifying the state of the microenvironment of the construction project and its leading participants. The theoretical basis for the functioning of development as an innovation and investment infrastructure of the construction complex is highlighted. The relevance of determining the success potential of the management decision and the success potential of the investment and construction project development is substantiated. Factors and risks that contribute to the failure of development projects in the construction industry are reflected. The results of the work allow top management of contractors to effectively monitor, structure and maneuver the assets of contractors in the process of their operations, provide a reasonable opportunity to adjust the economic strategy and parameters of the production portfolio of construction companies. The substantiation of the content of the leading functions of the "organizational structure" as a temporary enterprise for the organization of construction and development of DBP type (construction project developer) includes: management of logistics, preparation and construction processes, ensuring the transformation of resources of the customer and its institutional partners; coordination and administrative-regulatory function, which is to ensure communications and institutional and organizational design of relations between institutional participants and executors of the project in the form of agreements, contracts and a functioning directorate for project administration; directing the development system and organizational structure of management to timely identify threats to the progress of preparation and construction of facilities. The adaptive methodology of organizational and technological development of the project cycle and its administration by a temporary development company is justified in such a way as to adjust the content of business processes in the middle of the structure to the essence of tasks and work life cycle. The methodology harmonizes the requirements and methodological approaches of the development system in construction with the requirements and standards set by the Project Management Institute, which includes the inclusion of tools for construction, in addition to BIM-modules, and special visual components - "sensitivity maps".

Link Model, a participatory rural appraisal (PRA) programme for micro-infrastructure construction funding aid, has received much attention in Bangladesh over the last few decades. This study aims to contribute to the latest phase of the Link Model project, launched in July 2016 by the Bangladeshi government. To this end, the authors conducted a field survey in Kalihati Upazila, which involved 102 villagers and 153 local representatives. The authors used the survey to examine the efficacy of the programme and to identify the key factors that contribute to its success. Results obtained from the questionnaire survey showed that the programme had high degrees of satisfaction and penetration in the surveyed villages. Moreover, the degree of satisfaction was unaffected by gender, religion, income or education background, which is notably consistent with the ideals of PRA. Villagers who understood the policy better were more satisfied with the micro-infrastructures developed through the Link Model programme. The ratings of union development officers (UDO) strongly correlated with the number of micro-infrastructures. Therefore, this study concludes that the key success factors of Link Model are (a) the understanding of villagers on the programme for quality and (b) the capability of UDO for quantity.

Full textAbstract:
The decline in apprenticeship in both the public and private sectors, the increasing use of sub-contractors as well as the uncoordinated approach in the informal sector are contributing factors to the shortage of skilled artisans in the construction industry. Artisans training can be introduced and implemented through the adoption of progressive implementation of construction processes commencing work from areas requiring low skill demands to areas of high skill demand. The success of this principle hinges on the collaborative effort of the key project stakeholders. The client should be willing to absorb extra cost and delays in the project; the design and contract documentation should facilitate on-site training, and the consultant actively guide the contractor and the construction processes to achieve the training objectives. The exploratory research method was adopted in this study and research revealed that this principle was used in a project in the UK and in the development of infrastructure in the tourism industry of South Africa .It is being recommended that the principle be adapted by the public sector for the development of small size infrastructures that can be repeated in many places. This will boost the quality and quantity of artisans, enhance employability, reduce rural urban migration and alleviate poverty.Keywords: Skilled artisans, on-site training, progressive construction processes, project stakeholders, contract documentation.

Purpose The authors argue that public project managers do not consider the iron triangle (cost, quality and schedule) primary important in measuring the success of their projects. To investigate which success criteria are important to public project managers, the authors interviewed 26 Dutch project managers who are employed by the government and who are responsible for managing infrastructural projects. The paper aims to discuss these issues. Design/methodology/approach In this research the Q-methodology is applied. Q-methodology helps to find for correlations between subjects across a sample of variables. Q-factor analysis reduces the individual viewpoints down to a few factors. A factor can be seen as the mathematical representation of an “average” perspective shared by a group of people. Findings Findings are based on the individual rankings of 19 success criteria; the authors distinguished three common perspectives: the holistic and cooperative leader, the socially engaged, ambiguous manager and the executor of a top-down assignment. In none of the perspectives the iron triangle criteria formed the top three to measure project success. Research limitations/implications The research results may have a national character. The way project success is perceived by public project managers may be culture dependent. For this the authors expand the research to other countries in the near future. Practical implications This paper contributes to the understanding of the public project manager by their private collaboration partners, like consultants, engineers and contractors. This will help them to understand their client and contribute to better collaboration in projects. Originality/value This paper shows that the difference in work attitude and value frame in the public sector leads to a specific view on project success.

Background: According to the 2019 Global Competitiveness Index (CGI) by the World Economic Forum, the infrastructure growth of Indonesia is placed on number 72 out of 141 countries and ranked 5th in the ASEAN countries. The growth of infrastructure in Indonesia is a result of the imbalance increase of developments of 10-55% annually with only a 1.9% annual increase in road length. There was a delay of 11.95%, with the high investment in the construction of this toll road and the low-interest rate of return of around 7.79%. Objective: The expected goal in this research is to have cost and time efficiency in implementing infrastructure on the toll road project. Materials and Methods: This research is using a combination of case studies and statistical analysis; the case studies and the implementation of the M-PERT and VE on the object. Statistical analysis using simulation tools Relative Importance Index (RII) analysis based on research instruments to the success of the implementation of Manual Program Evaluation and Review Technique (M-PERT) and Value Engineering (VE) on toll road projects. Conclusion: The results of research with the analysis RII reveals that 10 important factors are affecting the performance of a project. The case study using the M-PERT method obtains a value of time accuracy of 98.87% of the real duration needed on site, while the VE method results in a revenue contribution outside of the toll income of 9.38% of the construction cost.

Full textAbstract:
Demand for the construction of retirement villages is increasing with the worldwide growth in ageing populations. However, the development of retirement villages can be impeded by many factors, such as limited available land and high investment costs. Public–private partnership (PPP) as an alternative financing mechanism has been widely applied in the construction of public infrastructure projects and may provide new funding sources for building retirement villages. By applying PPP to the construction of retirement villages, the independent living requirements of seniors can be met and the financial difficulty of the construction of retirement villages can be resolved. Similar to other PPP projects, when retirement villages are constructed under a PPP process, the concession period is a key decision variable in relation to the success of the project. The concession period is stated in the project contract between the government and private investors, and stipulates the date when the project ownership and operation are transferred from the private investor back to the government. The government should take detailed information into consideration at the initial project stage when determining the concession period. This paper proposes PPP as a new procurement method to be applied to the construction of rental retirement villages and develops a concession period determination process for PPP retirement village projects with consideration of real options, focusing on the option to defer. An empirical example with alternative scales, which is developed from an existing retirement village in Geelong, Australia, is used to numerically verify the process and the impacts of key variables on the concession period. The determination process provides an alternative tool for governments to design the concession period before the tendering stage and will benefit the development of industries associated with services for the ageing population. This process can also be applied to the construction of other financially non-viable PPP projects such as social housing.

Full textAbstract:
The inadequate risk management of public–private partnership (PPP) projects is a principal cause of project distress or failure. This research seeks to identify and empirically validate measures of effective risk management (ERM) in the context of PPPs in a developing country, a subject that has received scant attention in the extant literature. The research is based on a comprehensive literature review, expert interviews and a questionnaire survey. Mean score ranking and factor analysis were employed to rank and group the identified measures, respectively. Tests were performed to determine the respondents’ agreement and establish the reliability and validity of the survey instrument. Analysis results indicate that all identified measures are important, are distributed over the entire project’s life cycle and exhibit a multi-organizational focus. The most significant measures focus on PPP-specific artifacts and procurement activities that are vital for ERM. Factor analysis established six critical underlying dimensions for the ERM of PPP projects. The extracted factors generally acknowledge the need for expert public- and private-sector project stakeholders with mature organizational structures, business processes and relevant experience to successfully handle and deliver PPP projects. Furthermore, a comprehensive PPP policy and sound legal and regulatory frameworks are essential for supporting the ERM of PPP projects. The findings will enable a better understanding of factors that influence the quality and outcomes of risk management efforts and promote sustainable infrastructure development via PPPs, where the success of a project strongly relies on positively managing a project’s risks in the economic and the social domains.

In supporting the success of infrastructure development, it is necessary to have good cooperation between owners, contractors and workers which must be supported by the implementation of a project management system. A construction project is a series of activities which are generally short-term, dynamic, with varying intensity of activities and limited funds. If the project construction implementation is not managed properly, it will become a conflict or dispute between the elements involved in project implementation. In the current reform era, improving the quality of public services is a demand for workers where workers have begun to understand their rights as workers/employees.
The purpose of the study was to determine the contractor's performance and to determine the perception of construction workers on the services of the company PT. Konawe Multi Usaha. The results showed that the perception of construction workers on the company's services at the company PT. Konawe Multi Usaha is rated by workers in the category of Fairly Good. There are factors that influence the perception of construction workers' satisfaction on company service satisfaction by using the Customer Satisfaction Index (CSI) analysis, the value of worker satisfaction is 73.43%, which means that the level of worker satisfaction is in the Satisfied category

Purpose This study aims to provide an example of how higher education institutions (HEIs) can use a successful campus infrastructure project to fund a student- and faculty-led, community-success platform that advances the sustainable development goals (SDGs). Design/methodology/approach The authors applied conceptual models for systems thinking and creating virtuous cycles to analyze Millersville University’s work to establish a community-impact, micro-grant fund using cost savings and utility rebates associated with a new campus zero-energy building. The analysis provides a case study that other HEIs can implement to create university and community virtuous cycles that advance the SDGs. Findings The case study suggests that as HEIs face increasing financial challenges, opportunities exist to capitalize on philanthropic giving and other funding sources to support community prosperity and increase university vitality through a shared responsibility paradigm centered on the SDGs. Practical implications This case study identifies specific funding sources that HEIs can use to fund campus and community sustainability projects using the SDG framework, mechanisms for establishing shared purpose around that impact and a conceptual model for thinking about opportunities to leverage philanthropic giving to create a virtuous cycle that increases university vitality through community impact. Social implications Constructing a campus zero energy building funded in part through philanthropic giving provided a unique opportunity to explore how a project’s success can be leveraged to create additional community successes. This case study offers an example for how to convert one success into a platform that funds projects that have direct community impact in one or more of the SDG goal areas. Originality/value This paper aims at bridging the gap between theoretical frameworks for community sustainable development and descriptive-only case studies by using a case study to demonstrate a conceptual model or framework for advancing community sustainability (Karatzoglou, 2013). The case study provides a unique model for using utility rebates associated with an infrastructure project that was funded through philanthropic giving to establish a fund for projects that support the community. Utility rebates associated with campus energy efficiency projects are often otherwise overlooked, used to fund additional energy efficiency projects or simply returned to a university’s operating budget. For some HEIs, this model may connect the work of facilities staff to student success in ways that have not previously been explored. For others, this alternative use of utility rebates may offer an opportunity to increase the investment value of utility rebate dollars by creating virtuous cycles within their communities that contribute to university vitality.

Full textAbstract:
Public–private partnerships (PPPs) are widely applied in the procurement of capital infrastructure, encompassing phases such as financing, design, construction, operation, and transfer. Of these, the operational phase of PPPs is particularly critical to project success given this is when revenues are generated, and costs recouped. However, the revenue stream will be exposed to numerous risks over the relatively long period of infrastructure operation. Management of PPP operational risk is therefore critical. Despite this importance, research dedicated to PPP operational risk management remains limited. Thus, this paper addresses this deficiency by systematically reviewing related studies and proposing an operational risk management framework. A qualitative bibliometric literature review is conducted on 60 papers pertinent to operational risk management, published across 12 peer review journals. Findings reveal that the industry lacks a systematic operational risk factor list, while the impacts of risks are rarely considered when allocating operational risk factors, and moreover that the research on the selection and efficacy of operational risk management strategies remains undeveloped. This study reveals where further efforts in the research of operational risk management of PPP infrastructure projects could be more fruitfully applied.

As infrastructural investments are vital in developing countries, it’ll not solely facilitate to foster the economic growth of a nation, however it’ll additionally act as a platform within which new kinds of partnership and collaboration may be developed. The developments of BOT have attracted participation of native and foreign non-public sector capitalist to secure funding and to deliver projects on time, within the budget and to the desired specifications. There are many complexities in projects because of the variety of factors in project’s trend and also the dependence of project primarily on national factors. Because of these complexities and their long-term operation, the projects meet with uncertainty and numerous risks. Effective risk management methods and good managerial skills are required in guaranteeing the success of the project. In recent years, due to substantial increase in the amount of construction companies along with the changes in the government administrations, the construction projects are exposed to cost and time overrun and has huge impact on the progress of works within the industry. Although, the sector is considered to be a key driver of economic growth, time and cost overruns threaten to limit the sector’s potential to help achieve the desired growth and ensure efficient capital expenditure.

Mega infrastructure projects (MIPs) are exposed to numerous interdependent risks of various natures which pose difficulties in risk management. Thus far, the research on the risk interactions of MIPs has been focused on developing static risk networks within a single category of risks, at certain stages of the project. It is essential to understand the risk interactions at various stages of MIPs to identify the key risks and key risk relationships that jeopardise their success. This is especially relevant nowadays, as MIPs are expected to be delivered sustainably. Therefore, to analyse the dynamic risk interaction of MIPs, initially, through literature analysis and expert interviews, combined with the four dimensions of sustainable development and the four stages of MIPs, 98 risk factors of MIPs were identified. Subsequently, semi-structured interviews were conducted to determine risk relationships and weights. Risk networks were developed for each stage of MIPs, and improved social network analysis was applied to these risk networks. Finally, the key risks and key risk relationships in each stage of MIPs were identified by analysing the changes of multi-level network indicators. This aided in determining risk control strategies. The results demonstrate that the key risks and key risk relationships are different for each stage of MIPs. Furthermore, the risks of different dimensions of sustainable development have different relationships at different stages. This research is the first to identify the risk relationships involved in MIPs by taking into consideration the whole project life cycle and its sustainable development. This research provides theoretical support for the risk management of MIPs, and strategic suggestions for controlling the risks at each stage of the project.

Full textAbstract:
The Chevron-operated Gorgon Project is located off the northwest coast of Western Australia and encompasses a number of mega-projects including an all-subsea upstream development of the Greater Gorgon gas fields, a greenfield gas processing facility including a 15MTPA liquefied natural gas (LNG) plant and a 300TJ/d domestic gas plant, and the world’s largest commercial scale carbon dioxide injection project. Due to its sheer size, scale and complexity, in addition to a number of unique characteristics, the Gorgon Project has required an extraordinary level of project execution planning. One aspect is the processing plant’s location on Barrow Island—a remote Class A nature reserve. Core to the project’s planning and success is a meticulous and robust environmental management system designed to protect Barrow Island’s unique flora and fauna. This includes stringent environmental measures such as limits on worker population and movement, quarantine requirements for all personnel, and materials and work adjustments for seasonal flora and fauna life cycles. The project’s scope of work is also being executed from three centres: LNG facilities centered in London, infrastructure centered in Perth and construction operations centered in London, Perth and Barrow Island (according to the phase and priorities of the project). This paper explores the following factors: the remote location of the gas fields; cohabiting industry with Barrow Island; minimising environmental impacts using efficient construction management methods such as modularisation; and working together as one team across multiple locations and time zones to demonstrate how the extraordinary can be achieved.

As an effective way of completing technically complex buildings or large-scale infrastructure projects, a joint venture contracting approach has recently been widely used in the construction industry. However, numerous unfavorable results can occur in practice when undertaking construction joint ventures (CJVs). The contribution of this paper is its exploration of the potential obstacles to CJV practices and identification of the root causes of failure. First, through a literature review, semistructured interviews, and a questionnaire survey, seventeen variables were identified; the top three obstacle variables were (1) inconsistent management styles, (2) incompatible organizational cultures, and (3) organizational policy differences. Second, four grouped factors were extracted: (1) unfair and noneffective management; (2) lack of communication, understanding, and mutual trust; (3) policy, management style, and organizational cultural differences; and (4) potential conflicts beyond the CJV partnership. Finally, several strategies were proposed. The research findings could not only contribute to knowledge of CJVs but also provide valuable insights into promoting broader, better applications of CJV projects and contributing to their success.

Abstract
Construction Projects is one form of activity that takes place in a limited period of time, with certain resources, to achieve results in the form of buildings or infrastructure. Construction projects involve contractors, project owners, planning consultants and supervisory consultants that are interrelated in a work agreement called a contract. Project delays for contractors will experience a loss of time and costs, because the benefits expected by the contractor will decrease or even not get the expected benefits that they may not even benefit at all. The delay in the completion of the project work will cause a loss to the Owner to the operating time of the project results, so that the use of the project development results will be delayed or late. The success of a construction project is determined by the suitability of time, cost and quality stipulated in the contract document. In the implementation of construction projects delays often occur due to the parties involved. This research was conducted with the aim of finding out the factors causing delays in the implementation of construction projects according to contractors, project owners and supervisory consultants. Conducted by distributing questionnaires to contractors, supervisors and consultants, the results obtained were processed using the SPSS program. The results of the study revealed that the factors that caused the delay in construction projects were the 3 most dominant were the lack of skilled labor in the category of human resources Unexpected weather falls into the category of external aspects, and differences in interpretation of work codes fall into the categories of organization, coordination and communication aspects

Proyek Konstruksi merupakan salah satu bentuk kegiatan yang berlangsung dalam jangka waktu terbatas, dengan sumber daya tertentu, untuk mencapai hasil dalam bentuk bangunan atau infrastruktur. Proyek konstruksi melibatkan kontraktor, pemilik proyek, konsultan perencana dan konsultan pengawas yang saling terkait dalam sebuah perjanjian kerja yang disebut kontrak. Keterlambatan proyek bagi kontraktor akan mengalami kerugian waktu dan biaya, karena keuntungan yang diharapkan oleh kontraktor akan berkurang atau bahkan tidak mendapatkan keuntungan yang diharapkan bahkan bisa tidak mendapat keuntungan sama sekali. Keterlambatan penyelesaian pekerjaan proyek akan menyebabkan kerugian bagi Owner terhadap waktu operasi hasil proyek, sehingga penggunaan hasi pembangunan proyek menjadi mundur atau terlambat. Keberhasilan suatu proyek konstruksi ditentukan dari kesesuaian waktu, biaya dan mutu yang ditetapkan dalam dokumen kontrak. Dalam pelaksanaan proyek konstruksi sering terjadi keterlambatan yang disebabkan oleh pihak- pihak yang terlibat. Penelitian ini dilakukan dengan tujuan untuk mengetahui factor penyebab keterlambatan pelaksanaan proyek konstruksi menurut kontraktor, pemilik proyek dan konsultas pengawas.

The implementation of the Public-Private Partnership (PPP) projects in South Africa has grown steadily since the late 1990s. However, these partnerships do not realise their potential with a decline in PPP transactions over the past decade. The drivers of success for PPP projects have become a subject of investigation to understand the downward trend. This study evaluates the different critical success factors pertinent to client characteristics that influence PPP projects in South Africa. The study followed a qualitative research inquiry that employs a grounded theory (G.T.) approach involving semi-structured interviews with nine professionals involved in PPP projects selected using a snowball sampling technique. Interviews were conducted on video conferencing and through phone calls. Seven responses were considered relevant to the research, and two were considered irrelevant and were disregarded. An in-depth analysis of the data gathered was conducted through a selective coding process using NVivo. The analysis revealed the research’s emergent themes: client experience and in-house technical capabilities; client risk attitude; client willingness to be involved and trust in the private sector, available financial markets, and political support and stability. By applying the framework established, the chances of success and decline in the use of PPP projects can be considerably improved in South Africa through greater engagement between the public and private sectors in infrastructure investment and delivery. The study’s main limitation is the smallness of the sample size and the use of the snowball sampling technique in which the initial respondents are likely to refer to other respondents who share similar points of view and beliefs. To counter this limitation, the researchers ensured that the convenient sample of initial subjects comprised professionals from different backgrounds.

Theoretical concepts of the modern university pay a lot of attention to the evaluation of financial performance of research activities. The attraction of government-provided R&D funding is associated with the creation and enhancement of the scientific potential, and the accretion of scientific knowledge, rather than its practical application, is prioritised. Research projects commissioned by the private sector represents the university's contribution to the needs of the real economy or the "market" value of the accumulated potential. In Russian management practice, both of these criteria have become part of the regular evaluation of HEIs performance along with many other parameters characterizing the success of HEIs in achieving the benchmarks of scientific development. The objective of the study is to identify the factors that increase the financial success of Russian universities in the field of R&D. The fundamental hypothesis is that there is a direct correlation between universities' revenues from R&D and the priority directions of the state S&T policy with regard to universities, including the increase in publication activity, enhancement of human resources potential and formation of innovation infrastructure. The information base of the study was formed by the results of monitoring the activities of educational institutions of higher education in Russia in 2016-2022 for 590 institutions. The financial performance of HEIs' research activities is assessed using three indicators: the share of R&D revenues in the total revenues of an educational organization; the amount of extra-budgetary revenues from R&D per one research project and faculty member; the share of extra-budgetary funds in R&D revenues. To assess the statistical significance of the relationships, the tools of regression analysis of panel data were applied. The main conclusion of the study is to prove the mutual correlation between the vectors of scientific development of the university sector, which have been set at the state level in the last 10 years. The focus on strengthening university science coupled with intensification of cooperation with the real sector of the economy has been synchronized with the tasks of growth of publication activity, material provision of scientists, renovation of the instrumentation base, construction of research and innovation infrastructure.

Full textAbstract:
There is an increasing need to accelerate the diffusion of biogas technology, to contribute to handling grand societal challenges. It is thus concerning that around 30% of all biogas projects are abandoned. Previous studies have found that challenges for deployment of bioenergy technology are mainly economic and financial challenges, market and infrastructure challenges, regulatory and administrative challenges, local opposition, site selection challenges and ecological aspects. Very few studies have however tried to understand how these different types of challenges specifically affect individual biogas projects. Also, no previous studies have identified where these challenges occur in the different phases of a project’s lifecycle (conceptualization, planning, and execution). A lack of understanding that limits the ability of both public institutions and project owners to ensure the success of biogas projects. The aim of this study is to fill this knowledge gap and provide a unique insight into the often very complex and long project lifecycle for the realization of centralized biogas projects. Results based on five comprehensive longitudinal case studies of attempts to realize centralized biogas projects, all taking place between 2008–2020 in Denmark, provide insight into how projects are specially affected by these different types of challenges, and shows that both successful and abandoned projects typically faced an array of challenges that project owners need to overcome. The study also from a bottom-up perspective provides insight into the implementation of national policies and initiatives assigned to the accelerated deployment of biogas technology in Denmark between 2008–2020 as well as critical factors at the local level driving the development.

Full textAbstract:
Poor productivity is one of the major challenges facing the oil and gas industry in Australia. This is evidenced by significant cost and schedule overruns on every major LNG development during the recent Australian LNG construction boom. In a world where gas is a global commodity that can be easily exported, the consequences of poor productivity mean that investment dollars are directed overseas to lower risk environments to the detriment of resource development in Australia. This extended abstract explores the causes of poor productivity and it argues that one of the principle reasons is a fragmented contracting strategy, which results in the scope being split among different contractors at various phases of the project lifecycle, requiring complex and often inefficient interface management. This combined with little commercial incentive for contractors to minimise cost for the subsequent phase of the project means the responsibility falls with the operator to optimise costs during the project lifecycle. This extended abstract proposes that BOOM commercial model and contracting strategy is one way to address the productivity challenge. This model incentivises the contractor to engineer to reduce construction cost and to construct to minimise operational and maintenance costs by ensuring the contractor has a significant stake. This better aligns the commercial interests of the contractor and operator. This extended abstract also addresses the types of infrastructure development the model is best suited to and some of the critical success factors required to deliver a successful BOOM outcome.

Abstract The implementation of e-tenders requires readiness from the aspect of human resources, technological and management capabilities and organizations. To find out the factors that influence the success of the e-tender for construction services in Palu, this research was conducted by involving stakeholders involved in the implementation of the e-tendering, namely consultants, contractors and project owners. Data were collected on the basis of questionnaire survey using Likert scale of 6 and 28 Critical Success Factors (CSFs) were used in the questionnaire survey. The total number of questionnaires distributed was 163, of which 119 were returned, giving a 71% response rate. Data were analyzed using Relative Rank Index (RRI) technique and the Spearman Rank Order Correlation statistical test among three categorical samples. The results show that there is no difference among RRIs’ consultants, contractors and project owners. It is also concluded that the successful implementation of electronic tenders is influenced by factors related to Availability of reliable, affordable, and fast internet services, Availability of reliable ICT infrastructures and computer equipment, Building positive workplace and knowledge sharing culture and also Regular education and training to develop the competence and capability of electronic tendering procedures and requirement

Predicting the duration of construction projects with acceptable accuracy is a problem for contractors and researchers. Numerous researchers and tools are involved in sorting out this problem. The aim of the study is to predict the construction duration using four analytical tools as an approach. The success of construction projects in regard to time depends on various factors such as selection of contractors, consultants, cost of the projects, quality of the projects, the quantity of the projects, environmental factors, etc. Presently available commercial tools in the market are not designed as universally common and concerned. Every tool performs well in a particular situation. The prediction of India’s highway road projects duration is the biggest construction issue in the country due to various reasons. To overcome this problem, the methodology of the paper adopts various strategies to find suitable tools to predict the highway road projects’ duration, in which it classifies and analyzes the collected data. As a part of this work, the details of 363 government infrastructure projects (traditional procurement) were collected from 2000 to 2018. The present study also adopts various tools for duration prediction such as artificial neural networks (ANNs), smoothing techniques, time series analysis, and Bromilow’s time–cost (BTC) model. The results of the study recommend smoothing techniques with a constant value of 0.3, which gave the remarkable very small error of 1.2%, and its outcomes become even better when compared to other techniques.

Full textAbstract:
The current young generation in Australia is increasingly facing issues around housing, and the demand for affordable and personalised housing alternatives to suit the needs of the younger population has given rise to a variety of housing options. The Build-to-Rent (BTR) housing supply model is one such option that was recently introduced with the aim to provide diversity and choice within the private rental sector (PRS). Although the idea of building housing infrastructure to rent is not new, the formalisation of the BTR concept is currently underway and requires a comprehensive understanding of the various factors influencing its successful adoption. With the introduction of big market players such as institutional investors, understanding the critical success factors (CSFs) for producing successful BTR projects is crucial for its adoption as a feasible option for housing provision, especially for the younger population. Through a systematic literature review approach using the Web of Science and Scopus databases, recent literature from 2011 to 2021 were reviewed to identify CSFs related to the BTR housing model. These CSFs help distinguish the BTR paradigm within the general housing market system. A total of 32 CSFs were identified through the review process. Major factors relate to investors’ interest and willingness, affordability, and housing reforms and awareness. These CSFs identify the key areas of interest within the BTR research which can help create a comprehensive understanding of the current BTR scheme, along with providing a baseline for future research.

Purpose The authors will give an overview of the railway market, with a focus on Morocco, before seeing the challenges to face, before listing some benefits of rail links in terms of development, ecology, security, space management, etc. The authors will then give an overview of the development of BIM, its benefits, risks and issues. The purpose of this paper is to verify that the BIM can provide the railway with the tools to face some of its challenges and improve its productivity. Design/methodology/approach This paper is part of our research project on the integration of BIM in railway, which is the result of a partnership between Colas Rail Maroc and the ENSAK of the Ibn Tofail University of Kenitra. The objective of this paper is mainly to confirm that the integration of BIM with the railway, through a theoretical and practical study, can have positive impacts. To do this, our methodology consists in studying briefly the development of the railway, the need to improve the budgets and schedules of the projects, to increase the productivity, before showing the advantages of the BIM in the sector of the Architecture, Engineering and Construction (AEC). The study of feedback from railway projects (chosen for their date of completion – beyond 2014, their size, their geographical situation in several countries and for the availability of literature in a new field) will confirm the initial hypotheses. Among the projects studied will be a project that has been the subject of an article written by the authors of this paper. In the discussion of the results, the authors will focus on the benefits, risks and limitations of integrating BIM into the railway. In conclusion, the authors are laying the groundwork for future research in the field. Findings The cases study discussed in this paper and previous research confirms the hypotheses of the literature. The integration of BIM into railway projects can have several advantages: collaboration, time saving, cost optimization, prevention of conflicts between networks, construction before construction, optimization of facility management, improvement of the quality of works, prefabrication. They also allowed us to illustrate the risks (status and appropriation of the BIM model, lack of standardization of versions or software and lack of understanding of the basics of schedules and specifications) and limitations (lack of feedback, lack of adaptability and convergence of tools). These experiences have also shown that the use of BIM is not just a technological transition, but a revolution in the project management process, which requires several key success factors (participation of all, commitment, change management and adoption of the collaborative approach). Visualization, collaboration and conflict elimination are the three main chapters where the benefits of BIM can be organized. In fact, there is a lot of intersection between these chapters, but they have been chosen as the main ideas around which all the benefits can be better understood. Visualization primarily addresses the benefits to an individual and improving one’s personal understanding as a result of using BIM. The collaboration refers to the cooperative action of several team members, which is encouraged and facilitated by BIM. Conflict elimination mainly concerns project-related benefits, such as conflict reduction, waste, risks, costs and time. For railway infrastructure projects, the main purpose of using BIM is to improve the design integration process, internal project team communication and collision detection to eliminate risk of rehabilitation. Research limitations/implications The application of the BIM process in railway infrastructure requires constant improvement. This concerns the development of libraries and the models available to all users in order to encourage the development of this methodology and, consequently, its use of information throughout the life cycle of an infrastructure work. Practical implications The case study of real projects incorporating BIM confirms the results of the literature review. The benefits of integrating BIM into rail projects are multiple and proven: cost control, decision support, avoids extra work due to design errors, improves detection of interface problems, improves planning of vision, help with prefabrication and facility management, etc. Finally, the BIM process is able to overcome delays in procedures slowing the development of the construction industry in many countries, especially in Morocco, because of the slowness of design (or downright bad design). Social implications The integration of BIM into rail is becoming a global trend. This integration requires government decisions and a maturation of technology and tools. The authorities of some developed countries studied (Sweden, UK, France, Germany) in the railways, at different stages of implementation, are adopting BIM in the process of setting up new railway projects. This political impulse is still behind in southern countries, such as Morocco. The trend and the data collected indicate an adoption between 2020 and 2030 of BIM in all/some AEC projects in developed countries. This will have an impact on other countries that will soon be doing the same, especially in the railway sector to adopt the BIM. Originality/value As part of the realization of this paper, we proceeded to the implementation of an electrical substation as part of the project to build 40 electric traction substations built by Colas Rail on behalf of ONCF.

Full textAbstract:
The article, based on previous research, presents a summary comparative analysis of factors and factors that directly influenced the formation and development of compact micro-district housing in the USSR, Eastern and Western Europe and North America in the postwar period. The emphasis is on comparing the initial factors and subsequent operation, "success" or "failure" of the relevant projects in terms of the experience of the coming decades, which is extrapolated to the current construction situation.
The urgent need for the rapid resettlement of large numbers of new urban populations, induced by the rapid urbanization of the mid-twentieth century, in Europe and the USSR was greatly exacerbated by the great destruction of housing during World War II. In the Soviet Union, this housing crisis had a corresponding negative background since the early 1920s, which only increased over time. These factors, combined with the rapid development of the engineering and construction industry and the background of post-war technological progress, led to the appeal of both architectural and power elites to functionalism and modernism in residential development and the crystallization of the idea of mass construction of affordable multi-storey housing with social infrastructure, grouped into micro-districts. However, the difference in economic conditions between the market and planned economy, on the one hand, and historically formed social factors in Europe and North America, on the other, led to different results with similar construction techniques in style and conditions in the 1950s - 1960s (which received the common name "international style").
