Green buildings help in sustainability, in terms of achieving energy efficiency and minimizing the utilization of natural resources. Additional benefits include long-term sustainable building management and maintenance. There is, therefore, compelling motivation for the building of sustainable projects. This inspiration has led to the development of the leadership in energy and environmental design (LEED) rating systems and projects by the United States Green Building Council and the Canadian Green Building Council. Proper building project management (BPM) of such projects is warranted. Pre-project planning is a crucial part of BPM that ensures delivery and performance of construction projects. Pre-project planning is defined as the process that encompasses all the tasks between project initiation and detailed design. There is a positive relationship between comprehensive pre-project planning and enhanced project performance. Given the motivation for environmentally sustainable projects and proper management of constructing such projects, diligent pre-project planning for such projects is required. This paper investigates the use of the LEED rating system in pre-project planning of sustainable construction projects by developing a matrix that combines the LEED and the Project Definition Rating Index (PDRI) developed by the Construction Industry Institute. The conceptual matrix and its application to a case study demonstrates that the value of linking pre-project planning with LEED to improve the decision making process during planning and designing of building projects to improve sustainability.

Real estate and buildings are some of facility managers’ most costly resources. Thus, knowledge about how to get the most out of building or renovation projects both in the short term and in the long term are of great importance for facility managers. This paper investigates which factors are most important for building and renovation projects’ output or short-term value creation, and outcome or long-term value creation, i.e., the completed building’s effect for owners and users. Thus, the focus is not primarily financial and the buildings’ asset value. The study is based on a national questionnaire survey in Norway (550 respondents). Multivariate statistics (Principal Component Analysis and Linear Multiple Regressions validated with bootstrapping) were used to test the hypotheses. Short-term project management priorities, such as early involvement of technical contractors and FM providers, contract strategy and involvement of owners and users largely decide the qualities of the building, and thus the potential for long-term value creation. The most important factors for long-term value creation, i.e., buildings that facilitate the demand organisation’s value creation are the qualities of the completed building, project governance and involvement of owners and users during early phase planning.

Abstract Risks have a large impact on the budget, schedule, and a building project's quality. As the magnitude and complication of the project grows, the ability to control risk throughout the building process has become critical in preventing unplanned consequences. The high-quality procurement and the element of the corresponding agreement terms influence how risks are divided among project players to a great extent. As a result, project players must choose the best project procurement alternative. This dissertation's main objective is to not only assemble a table of building construction hazards, but also to identify the most important risks that can have a great influence on construction and mitigation methods. Assess and identify the most suitable countermeasure for the construction field in order to minimize hazards in future projects. The post-project appraisal method is applied in this dissertation to discover the list of hazards involved with the construction field. The questionnaire survey was conducted at several building projects, and the results were analysed once the survey was completed. The RRI method (Relative rank index) filters the response. Following this strategy, the AHP (Analytic Hierarchy Process) method is used to obtain more precise factors that affect project risk. The risks were discovered as a consequence of the analysis, and recommendations were made.

Testo completoAbstract (sommario):
Sustainable building projects have levels of complexity over conventional building projects that challenge current project management tools at efficiently managing the rigors of sustainable projects. The Continuous Value Enhancement Process (CVEP) is a recently developed tool designed specifically for sustainable building projects. This project management tool enables project teams to systematically generate and evaluate project alternatives for meeting sustainable goals. The goal of this tool is to identify high performance solutions that increase levels of sustainability and improve project performance. CVEP was experimentally implemented and tested on four case study projects to evaluate its ability to support project management decision making in ways that elevate sustainability and project performance. Reported in this paper, the results show CVEP produced first cost and life cycle cost savings. In particular, the study confirms that CVEP has the capability to: 1.) Provide a systematic evaluation process, 2.) Collect high performance building solutions, and 3.) Be applicable to different project types. These results show that it is possible to employ targeted project management techniques, like CVEP, to improve the cost-effective provision of sustainable buildings.

Purpose – The purposes of this paper are to: investigate schedule performance of new and retrofitting green building projects; identify the critical factors that influence the schedule performance of new and retrofitting green building projects; and provide solutions to improve schedule performance of new and retrofitting green building projects. Design/methodology/approach – A questionnaire survey were conducted and responses were received from 34 firms experienced in green building projects in Singapore. After the data from the survey had been analyzed, face-to-face interviews were conducted with two senior project managers to solicit comments on the survey results. Findings – This study identified the degree of project delay in 98 new green building projects and 51 retrofitting green building projects in Singapore. The result indicated that 22 percent of the Singaporean green building projects were plagued with delay and retrofitting projects had a significantly higher likelihood of delay and significantly longer extension than new projects. In addition, “consultant cooperation to solve problems” was the most influential to schedule performance of both new and retrofitting green building projects, and the two project groups agreed on the overall ranking of the factors affecting schedule performance. Research limitations/implications – There may be geographical limitation on the conclusions drawn from the findings. Also, the sample size was still small, despite a relatively high response rate. In addition, the majority of the respondents were contractors as other project players were reluctant to respond to the survey. Practical implications – This study provides a clear understanding of the schedule performance of green building projects as well as the critical factors that should be highlighted when constructing green building projects. Also, strategies to overcome the negative impact of these factors allow practitioners to better deal with the potential causes of delay and to attain the schedule performance. Originality/value – Although construction delays have been widely investigated in previous studies relating to construction management, few have attempted to analyze the schedule performance of new and retrofitting green buildings. Thus, this study adds significantly to the existing research on both green building and construction delay.

Purpose This paper aims to investigate how knowledge concerning operation and maintenance of buildings can be stored and transferred between the parties responsible for building operation and new building projects. Design/methodology/approach The paper is theoretically based on knowledge management with a particular focus on interdepartmental knowledge transfer between departments responsible for operation and maintenance and departments responsible for building projects in organisations with large and fast changing building portfolios. The paper includes a case study of the facilities management organisation of the Technical University of Denmark with data collection mainly by interviews with managers and staff in the relevant departments in this organisation. Findings The case organisation seems to be aware of the importance of sharing and transferring their organisational knowledge. Over the past five years, the organisation has developed different tools and adopted several processes, aiming at integration of the knowledge they possess from many years of operation and maintenance of the existing buildings. However, there are many situations, where the tools and processes do not work efficiently, and therefore the knowledge transfer is not sufficiently effective. It is apparent that the best results can be achieved only if the different actors involved in a construction project collaborate aiming towards the same objectives. Originality/value The paper presents and evaluates a case of interdepartmental knowledge transfer in an organisation, which has a strong focus on improving the interconnections between building operations and planning new building projects.

Green Mark, a certification for Green Building (GB), has become a compulsory requirement for all new buildings in Singapore. The aim of this study is to explore the controllable critical project management factors of Architectural, Engineering, and Construction (AEC) firms for delivering Green Mark certified projects and examine how these factors can be useful. Based on three case projects in Singapore, the factors influencing the success of GB were identified. It was also observed that the higher ratings of the building projects, the more management factors should be given proper attention. The research findings could assist project managers in managing the overall project performance and successfully implementing Green Mark certified projects more effectively.

Testo completoAbstract (sommario):
In civil engineering, concrete plays a vital role, but for the construction technology of concrete, it is necessary to have a perfect management and supervision system to ensure the quality and ensure the smooth progress of the project, so as to improve the implementation process of construction projects. At present, most of the construction projects in China are large-scale composite buildings using concrete materials. Therefore, the implementation of concrete structures and the quality of construction technology are directly related to the quality of the whole project. It can be seen that concrete engineering plays a vital role in the whole construction project. However, as far as the current building projects are concerned, there are still many problems in the construction of concrete projects. Cracks also occur in the high-rise buildings. Cracks also exist in the bottom of high-rise buildings and the bottom of some bridges, which makes the buildings have potential safety hazards. This has to worry people.

Testo completoAbstract (sommario):
Historic and heritage buildings present a significant challenge when it comes to reducing energy consumption to mitigate climate change. These buildings need careful renovation, and increasing their energy efficiency is often associated with a high level of complexity, because consideration for heritage values can often reduce and impede possibilities and sometimes even rule out certain improvements completely. Despite these issues, many such renovation projects have already been carried out, and therefore the IEA SHC Task 59 project (Renovating Historic Buildings Towards Zero Energy) in cooperation with Interreg Alpine Space ATLAS has developed a tool for sharing these best-practice examples—the HiBERatlas (Historical Building Energy Retrofit Atlas). The Internet serves as a best-practice database for both individual energy efficiency measures and whole-building renovation projects. This paper presents two of the Danish projects featured in HiBERatlas. The first project, Ryesgade 30, is a Copenhagen apartment building with a preservation-worthy period brick façade. The second project is the Osram Building, a listed Copenhagen office building from 1959 with a protected façade, which today acts as a culture centre. Both renovation projects achieved significant energy savings and consequently CO2-emission reductions, and the indoor climate in both buildings have also improved significantly. Furthermore, a detailed analysis was carried out regarding possible window solutions and ventilation systems in Ryesgade 30, and for the Osram Building regarding daylighting technologies. This paper investigates the two renovation cases through the available measurement and calculation results before and after renovations and demonstrates that it is possible to reduce energy consumption significantly and at the same time improve the indoor climate without compromising the cultural values of buildings.

Nowadays, we can observe a growing interest in passive buildings due to global climate change, environmental concerns, and growing energy costs. However, developing a passive building is associated with meeting many Passive House requirements, which results in their increased complexity as well as many challenges and risks which could threaten the successful completion of the project. Risk management is a key tool enabling meeting today’s challenging passive house project’s demands connected with quality, costs, deadlines, and legal issues. In this paper, a new model of risk management dedicated for passive buildings based is proposed, in which a novel Fuzzy Fault Tree integrated with risk response matrix was developed. We proposed 171 risk remediation strategies for all 16 recognized risks in passive buildings projects. We show how to apply the proposed model in practice on one passive building example. Thanks to applying the proposed risk management model an effective reduction of the risks of the basic event is enabled, leading to a significant reduction of the top event risk. The proposed model is useful for architects, installation designers, contractors, and owners who are willing to develop attainable and successful passive buildings projects that benefit all stakeholders.

Building energy renovations can effectively improve the environmental performance and energy sustainability of existing buildings. From 2007 onwards, the Chinese government has promoted energy-saving renovations of existing urban residential buildings. Nevertheless, various quality failures happen during the construction period in energy-saving renovation projects of residential buildings. Yet, the causes and their characters remain largely unknown. Through a literature review, this paper investigates the causes of quality failures. Validated through experts’ interviews, a total of 18 causes were identified in building energy renovation projects. These causes were analyzed from two main aspects: the importance of a cause (related to impact and frequency), and the level of effort required to address a cause (related to origin and scale), using both a questionnaire survey and a focus group. The results indicate that the critical causes of quality failures are working under high-cost and high-time pressure, adverse natural conditions, fraud of construction companies, incomplete construction site survey, poor checking procedures of supervisors, poor operational skilled workers, inadequate equipment performance, lack of experienced project managers, and incomplete building information in projects. The causes were classified as external and internal causes of building energy renovation projects. The outcome of this paper should aid policy makers and project coordinators to focus on critical causes of quality failures, and to develop effective actions and policy interventions to achieve successful renovation projects with high-quality performance.

Presently, the refurbishment approach becomes favourable as it creates opportunities to incorporate sustainable value with other building improvement. In this regard, this approach needs to be implemented due to the issues on overwhelming ratio of existing building to new construction, which also can contribute to the environmental problem. Refurbishment principles imply to minimize the environmental impact and upgrading the performance of an existing building to meet new requirements. In theoretically, building project’s performance has a direct bearing on related to its potential for project success. However, in refurbishment building projects, the criteria for measure are become wider because the projects are a complex and multi-dimensional which encompassing many factors which reflect to the nature of works. Therefore, this impetus could be achieve by examine the direct empirical relationship between critical success factors (CSFs) and complexity factors (CFs) during managing the project in relation to delivering success on project performance. The research findings will be expected as the basis of future research in establish appropriate framework that provides information on managing refurbishment building projects and enhancing the project management competency for a better-built environment.

Background: Building construction projects have very complex activities, so they require precise and accurate methods of scheduling and control. Using the right method, the project executor can carry out the project according to plan and any schedule deviations can be controlled effectively. This study aims to compare the effectiveness of using the bar chart/S-curve and computerized precedence diagram method (PDM) on scheduling and controlling building construction projects. Methods: The use of the two methods and their effectiveness during project work were analysed using a survey directed to building construction workers. Results: A total of 50 workers completed the survey. The use of PDM (using Microsoft Project) was significantly more effective than the bar chart/S-curve method in scheduling building construction projects (t count 15.516> t table 2.660) and controlling building construction projects (t count 17.233> t table 2.660). In addition, PDM was associated with allowing the project to find the critical path more quickly, overcoming project delays more effectively. Conclusions: By using PDM, a on a building construction project’s schedule for the implementation of the work can be changed immediately, if there is a delay or deviation of work. The findings of this study are useful for construction service companies and the development of construction management science in civil engineering study programs.

Nowadays, Construction project faces many challenges in term of a control system and monitoring tools as well. Besides that, the construction projects building energy applying artificial intelligence (AI) systems play an essential role in the energy management of buildings and also the way to conservation it. By taking into account that using artificial intelligence (AI) systems can assist the construction project to evaluate the effectiveness of the different buildings such as conduct building commissioning energy efficiency, and even though detect and diagnose construction project system faults. However, construction projects are how artificial intelligence (AI) systems implemented their strategies. Thereby, construction project indicators of efficiency are still limited without implemented artificial intelligence (AI) system. In this study, artificial intelligence (AI) is a serious situation that has a high efficiency that can positively affect construction projects. Positive result estimation can be suggested in terms of an identified critical element of success.

A complete definition of the scope of a project upfront during early stages ensures smooth and successful implementation during the project execution. This research identifies and prioritises project scope definition elements for public buildings in Saudi Arabia. Elements that could significantly contribute to complete project scope definition package at pre-project planning stage are identified and their interrelationship determined and prioritised. Using the Project Definition Rating Index (PDRI) as a basis, the study uses analytical network process (ANP) technique based on data obtained from project managers who have been involved in public sector projects in Saudi Arabia. Data collection and analysis was conducted in three steps. The first step involved identification of scope definition elements while the second involved an investigation into interrelationships among the elements. In the third step, ANP was used to determine the weight of the elements’ importance in terms of contribution to project scope definition completeness. Finally, Pareto analysis was used to prioritise and assess the distribution pattern of the elements. The outcome from this research is the prioritisation of project scope definition elements for public building projects in Saudi Arabia. The prioritised list developed indicates the importance of project scope definition elements. It should help project management teams identify elements to consider when evaluating project scope definition for completeness at the pre-project planning stage.

Success in mega-projects is frequently discussed among project theoreticians and practitioners. This research focuses on high-technology projects and draws on recent literature and fieldwork at ten contemporary mega-science projects in Chile, Australia, and Europe. This study concludes that project success is not random, and early adoption of certain approaches, activities, and launch conditions will position a project for success and resilience. Nine resilience factors (beyond a priori programmatical artefacts) are grouped into three ‘attitudinal’ factors, and six ‘conditioning’ factors and then examined in detail against three case study projects. The study’s conclusion show that attitudinal factors remain a challenge, especially within institutional type high-tech projects, and launch conditioning shows mixed levels of application. Through the nine factors, this paper offers newly consolidated insights for high-tech project start-ups and presents the case for co-application of contingency funding and ‘proto’ task forces in response to unknown risks, and advocates the establishment of more formal information ‘traffic’ management through an empowered centralised project information office.

Building Information Modelling (BIM) plays a major role in enhancing the building project process. However, BIM implementation in building projects has not been categorized, and no previous investigation of its value in the different building project types has been undertaken. This research intended to evaluate BIM implementation in building projects and to identify its values, challenges, and enablers. Experts from BIM consultancy organizations were the respondents in this study. Based on nine interviews and 26 responses to a structured questionnaire, a quantitative approach to the content validity method was adopted. The results reveal that BIM implementation in mid- and low-rise buildings is very low. Only top organizations are able to implement BIM in their projects. Experts suggested that local organizations are not able to implement BIM due to their inability to adopt the BIM system as a digital management process throughout the project life cycle. In addition, there was consensus agreement based on the Content Validity Ratio (CVR) that BIM adds significant value to building projects, which includes providing collaborative organizations, greater communication, increased client satisfaction, more cost-savings, increased productivity, and a new way of reasoning for projects. This research also identified 20 challenges and 45 enablers of BIM implementation in mid- and low-rise building construction by the local firms. From the result, it was found that the presented variables were reliable, as reported in the interview transcripts and based on the majority of experts’ opinions. This research provides an important list of challenges and success factors that need to be considered to overcome the critical issue of low BIM implementation in building projects.

Along with the growing interest in greenhouse gas reduction, the effect of greenhouse gas energy reduction from implementing green buildings is gaining attention. The government of the Republic of Korea has set green growth as its paradigm for national development, and there is a growing interest in energy saving for green buildings. However, green buildings may have financial barriers that have high initial construction costs and uncertainties about future project value. Under the circumstances, governmental support to attract private funding is necessary to implement green building projects. The objective of this study is to suggest a financing model for facilitating green building projects with a governmental guarantee based on Certified Emission Reduction (CER). In this model, the government provides a guarantee for the increased costs of a green building project in return for CER. And this study presents the validation of the model as well as feasibility for implementing green building project. In addition, the suggested model assumed governmental guarantees for the increased cost, but private guarantees seem to be feasible as well because of the promising value of the guarantee from CER. To do this, certification of Clean Development Mechanisms (CDMs) for green buildings must be obtained.

Testo completoAbstract (sommario):
Purpose The continuous failure of construction projects notwithstanding appreciable increase in project management knowledge has necessitated a proactive approach of assessing early warning signs (EWS) of building projects failure. Building projects are expected to show warning signs before experiencing crises, comparable to a patient displaying symptoms of a disease. Thus, this study aims to examine the EWS that predisposed building projects to failure in Nigeria to provide empirical data for enhancing projects delivery. Design/methodology/approach Primary data were used for the study. Structured questionnaire was administered to consultants and contractors’ personnel within Lagos State, Nigeria. A total of 180 copies of questionnaire were administered and 134 copies (combined response rate of 74.44 per cent) were retrieved. Frequency distribution, percentages, mean item score and Mann–Whitney test were used to analyse the data. Findings Most construction professionals applied the EWS approach from project planning and early construction phase. The most significant EWS predisposing building projects to failure were “Management inability and incompetence to proactively detect and manage problems at early project stages”, “Actual expenditure is constantly shooting beyond cost estimates” and “Incurred costs already getting higher than the anticipated benefits”. Project/construction management-related symptoms are most significant to predisposing building projects to failure. Practical implications The study provided implications for effective project management of building projects through proactive approach which is very paramount to improving the delivery of building projects in Nigeria. Originality/value The study provides implications for proactive management of building projects, thereby enhancing the delivery of building projects.

Green-building rating systems (GBRSs) are critical for implementing climate change (CC) mitigation strategies because they can help reduce greenhouse gas (GHG) emissions from the building sector. From the Indian policy perspective, the ClimateSMART Cities Assessment Framework (CSCAF) provides cities a roadmap toward mitigating CC while planning/implementing their actions and facilitates realising energy efficiency and green buildings through GBRS adoption and incentivisation. Green Rating for Integrated Habitat Assessment (GRIHA) is a comprehensive GBRS aligned with CSCAF and India’s climate goals, facilitating the implementation of Government of India’s relevant policies and climate-adaptation measures within a building project’s different phases. This paper examines existing institutional mechanisms for incentivising GRIHA-rated projects and provides recommendations for municipal bodies, regional developmental authorities, and state governments for strengthening resource efficiency in the built environment through GRIHA. Residential buildings are considered because their contribution to GHG emissions is the greatest among buildings. Data were collected through literature review, reviewing smart-city proposals and latest state annual action plans, Right to Information queries, and structured interviews of stakeholders. Feedback from green-building certification agencies, project proponents, and government officials revealed a need for local-level information dissemination and guidance on institutional mechanisms for incentivising green-rated projects. Further, to understand the implementation mechanisms for GRIHA-linked incentives, residential projects under some local-government agencies were documented as case studies, providing useful insights into prevalent mechanisms for availing incentives while facilitating GRIHA compliance.

Purpose – With pressing issues of climate change, greening buildings have emerged as a viable solution for meeting the increasing demand for buildings with minimal environmental impacts. Hence, the purpose of this paper is to establish the possibility of achieving this goal by investigating the drivers, challenges, and critical success factors (CSFs) involved in greening existing buildings. Since most of the relevant literature focuses on only acknowledging CSFs for new building projects in general, this study seeks to distinguish CSFs that are particularly related to the greening of existing buildings. Design/methodology/approach – Based on a review of past literature, 28 selected factors were identified and were categorised into five main groups, namely pre-project-related factors, project management-related factors, client-related factors, project team-related factors, and external factors. Because older buildings have more constraints than new buildings, a comparison of the CSFs for greening new and existing buildings was also made. Surveys and interviews were conducted to validate the CSFs identified. Findings – The top CSFs in each building category (new vs existing) were then further examined and analysed. These are “top management support”, “effective planning and control”, “building owner's involvement”, “cost management”, “responsiveness of building owners”, “clear scope and priorities of stakeholders”, and “legislation”. Furthermore, there was a strong consensus on the rankings of most factors between new and existing buildings. Research limitations/implications – By understanding the factors that are crucial for managing and delivering successful green projects in the Singaporean context, these CSFs can be used to direct an organisation's efforts in identifying critical issues and tackling them to achieve high performance. Originality/value – An ambitious goal of greening 80 per cent of Singapore's building stocks has been set by the government in the Second Green Building Master Plan. To help achieve this goal, this study contributes to the knowledge of project management issues that would determine the success of managing new green building projects and retrofitting existing ones.

PurposeThe objective of this paper is to present different perspectives on building “trust” among supply chain participants working on construction projects.Design/methodology/approachA case study methodology was adopted; with five construction projects selected as five case studies for the trust in construction project on the basis a selection criteria devised for the research project. Over 40 interviews were conducted with participants operating at different levels in their respective organisations and at different point in the supply chain.FindingsThe information provided by the multiple informants was, to a large extent, consistent with much of the academic literature relating to the importance of and barriers to trust. Specifically, the case studies highlighted: what people within the construction industry understand by trust, reliance, and honest professional relationship; the key factors that contribute towards building trust and factors that result into breakdown of trust; and organisational and project related factors that influence trust and relationships among people within the industry.Research limitations/implicationsThe findings from this study are limited due to: a small number of case studies undertaken, focused within the North West Region of England, and limited time and resources available. However, the ideas proposed for ways to develop trust in construction projects as seen from project findings have important implications for not only the clients but also for the main contractors and sub‐contractors who need to pay greater attention to build trusting and long‐term relationship as part of an integrated supply chain in order to deliver the continuous demand for services especially from public sector clients.Practical implicationsIf more businesses operating in the construction sector gave more thought to the importance of trust in construction projects then this could have a significant impact on contract design and over all procurement strategy. Specifically the repetitive work carried out by the local authorities in the UK, such as school building and maintenance, social housing stock improvement, etc., can be subcontracted to the contractors on a longer term basis resulting into long term supply chain relationship among organisations and cost savings.Originality/valueThe research is among the first attempts in response to Latham report published in 1994, in order to explore the role of trust in construction projects, from the perspective of multiple stakeholders. The paper provides insights into the practical issues that prevent the widespread development of trust within the construction industry, which is a challenge that clearly warrants further attention from academics and practitioners.

What shape do two galaxies take when they collide? How long does a newly introduced virus take to spread through a city the size of Chicago? Such questions are often difficult to answer because the phenomena are difficult to observe directly. The perceptible motion of galaxies occurs over time scales that are greater than the entire history of mankind; and it is thus impossible to truly observe even with a lifetime of study. Although the spread of a virus might be indirectly observable through reports at local hospitals, pinpointing an original carrier and tracking infected individuals is neither plausible nor particularly desirable.

Abstract LEED (Leadership in Energy and Environmental Design) is one of the prestigious green building rating systems globally and the widely accepted international standard to evaluate green buildings. Many LEED certification building projects have already been carried out over the last few decades in the Kingdom of Saudi Arabia. Recently, many construction projects underway in the Kingdom are expected to be nominated for LEED certification over the next few years. The paper explores the recent application of the LEED rating system in building construction projects and reviews the trends, project types, and potential challenges of the LEED certification buildings in the Kingdom. The study also investigates differences and characteristics in the types of LEED certification projects in the Kingdom and the Middle East countries, such as UAE, Qatar, Egypt, etc. The differences in the rate of adoption of the LEED categories in each country are indicated closely through the detailed analysis. As a result, the paper presents the current trends and future perspectives based on the current status of the Kingdom's green building industry. This is a critical milestone to accelerate the development of the green building industry in the Kingdom.

Building maintenance projects have been characterized by poor quality delivery, which leads to client dissatisfaction. The maintenance contractor’s personnel evolve around the uncertainties that surrounds maintenance decisions, which makes the success of a maintenance project dicey. Hence, this study seeks to identify critical success factors that determine the performance outcome of building maintenance projects in Lagos State, Nigeria. A quantitative research approach was adopted for the study using questionnaires and interviews for data collection. Mean score, ANOVA, and factor analysis was employed for the analysis of the data collected. The findings of the study indicate that the eighteen identified factors can be grouped under six critical success factors named team integration and knowledge transfer, project learning and maintenance methodology, stakeholders’ early project assessment, planning and control, information and communication management within project stakeholders,and quality and risks control. The effective management of these factors will improve building maintenance project’s outcomes in Nigeria

Testo completoAbstract (sommario):
Green buildings have recently become a key aspect of the construction field and bring along a renovation of the whole industry chain. Such changes introduce new challenges for all subjects involved, and designers are also affected by such issues, especially for the development of projects based on international green building standards. Within this scope, project management plays a key role in the optimization of the design phase. This research analyzes the design process of international projects from the project management perspective through a multiple case study approach, considering the sustainability-related tasks that negatively affect the project design development under two types of contractual approaches: Design-Build and Design-Bid-Build. It aims to identify whether the Design-Build or Design-Bid-Build process is the best solution for developing green building projects. Two case studies in Italy and two case studies in Spain are analyzed, and the effects of the project management issues are evaluated under three different points of view: Time, cost, and level of sustainability of the building. A poorly planned process for the achievement of the various green building features of the project can impact the project schedule and the budget, whereas, a poorly managed project could also negatively impact its green building features. Finally, this research also highlights the positive relationship between process integration and green building design development.

Testo completoAbstract (sommario):
Purpose The purpose of this paper is to identify critical non-value adding (NVA) building information modeling (BIM) implementation activities in current building project delivery process, develop a BIM implementation readiness (BIMIR) evaluation model, and assess BIMIR statuses in building projects in Singapore. Design/methodology/approach A questionnaire survey and four post-survey interviews were conducted in Singapore. A fuzzy synthetic evaluation approach was adopted in the model development. Findings In total, 38 out of 44 NVA BIM implementation activities were deemed critical and used in the proposed model, among which “lack of involvement by contractors to contribute site knowledge” in the design development phase was ranked top. This model was validated in five projects. It was found that most of 73 surveyed building projects were in a low BIMIR status and the assessment results were consistent with current industry practices of BIM implementation in Singapore. Research limitations/implications There may be geographical limitation on the identification of the critical NVA BIM implementation activities. However, because BIM mandate spreads globally, the findings can help overseas project teams customize their own NVA activities and evaluation models. Practical implications As BIM implementation is mandated in Singapore, BIMIR evaluation helps local project teams identify weak areas of their BIM implementation activities and prioritize resources to enhance those areas. Originality/value No tool has been developed for evaluating BIMIR at the project level in the construction industry in Singapore or at large in Asia. Four BIMIR statuses are defined, which are consistent with Singapore’s BIM guidelines and standards.

Testo completoAbstract (sommario):
WBS (Work Breakdown Structure) plays an important role in every construction project. WBS is a hierarchy of decreasing scope of work to become the smallest level called a work package, making it easier in the process of project management and control. The current problem is that many contractors in Indonesia, both large and small contractors, do not understand the importance of using WBS in a construction project. This causes project performance to be less than optimal, especially on cost and time performance. Currently, WBS standards have been developed for building projects. In this study will look at the cost and time performance of the project from the use of WBS standard building. The sample used in this study are projects that have applied the use of project standards. The projects include Building X, Lecture Building Y, and Sports Facility Building Z. The method used in this study is the EVM (Earn Value Method) approach, collecting data using questionnaires. The results showed that using the WBS standard had an effect on cost and time performance. Good cost and time performance is shown in the Building X and Lecture Y buildings. While the cost and time performance of the Z Sports Facility Building tends to be unstable. This is because the work items that exist in the WBS standard are not in accordance with the project conditions, so it is necessary to adjust work items.

Testo completoAbstract (sommario):
Construction renovation projects increase the risk of structural fire, mostly due to the accumulation of combustible construction materials and waste. In particular, when the building remains operational during such projects, the redistribution of occupants and interruptions with access corridors/exit egress can exponentially increase the risk for the occupants. Most construction projects are, however, planned and scheduled merely based on the time and budget criteria. While safety is considered paramount and is meant to be applied as a hard constraint in the scheduling stage, in practice, safe evacuation considerations are reduced to rules of thumb and general code guidelines. In this paper, we propose simulation as a tool to introduce safety under structural fire, as a decision criterion, to be mixed with time and budget for selecting the best construction schedule alternative. We have used the BIM (building information model) to extract the building’s spatial and physical properties; and have applied co-simulation of fire, through computational fluid dynamics (CFD), and occupants’ evacuation behavior, through agent-based modeling (ABM) to estimate the average and maximum required safe egress time for various construction sequencing alternatives. This parameter is then used as a third decision criterion, combined with the project’s cost and duration, to evaluate construction schedule alternatives. We applied our method to a three-floor fire zone in a high-rise educational building in Montreal, and our results show that considering the fire safety criterion can make a difference in the final construction schedule. Our proposed method suggests an additional metric for evaluating renovation projects’ construction plans, particularly in congested buildings which need to remain fully or partially operational during the renovation. Thus, this method can be employed by safety officers and facility managers, as well as construction project planners to guide accounting for fire incidents while planning for these types of projects.

Abstract In order to improve the performance of green office building projects, proper contractual behaviour of key participants is perceived as one of the best initiatives, given that it serves as the primary function in guiding the smooth management of green office building projects. This paper aims to identify the criteria in managing green office building projects. It was found that this reports on the results of the content analysis which collected data on design and features of green office building implemented by the designers. A list of GBI -Certified Green Office Buildings under New Construction Category in Malaysia was assessed. Five (5) numbers of office buildings in Klang Valley and Putrajaya area were selected to present features of green office buildings applied by the designer to fulfil the green building criteria hence achieving GBI certification. The features of each green building obtained from various relevant websites were compiled based on the six (6) criteria listed under GBI. Though the system and materials might be slightly different from one green buildings to another, there are similarities in terms design principal; by incorporating advanced green technologies, sustainable energy solutions, innovative energy management systems and rainwater harvesting systems into the design. Thorough consideration has been given by the project team to produce a building that is environmentally, socially and economically friendly. This is achieved by enhancing good passive designs and integrating active (mechanical and electrical) design and system to deliver and to offer significant long-term comfort and savings for the building owners and occupants.

This research concerns the delivery of sustainable building projects. These projects are defined as those which either attempt to achieve green ratings or are claimed to address certain sustainability issues. A key focus is to examine how the client's vision for sustainability is achieved or compromised by the practicality of construction. Two sustainability rating systems, the Australian Green Star and the Living Building Challenge from the U.S. are discussed. This research examines two projects; one university multipurpose building (SMART Infrastructure Facility); and an advanced research facility, the Sustainable Buildings Research Centre (SBRC). The methodology used is semi-structured interviews of key participants and stakeholders for the two university building. The outcome of this research indicates that environmental rating systems are useful tools to construct reasonably sustainable buildings. Many interviewees, however, believe that for their next projects the concern would be to continue to construct sustainable buildings but not necessarily by following the strict criteria and reporting requirements of the environmental rating system.

Testo completoAbstract (sommario):
In most cities of developing countries, old buildings always tend to undergo redevelopment. There are one or more than one reasons for this. Such as buildings which are in dilapidated condition or uneconomic to repair or tenants are in a need of more usable floor area. This activity of building redevelopment is much visible in Mumbai city for past decade and half. Because of various constraints and considerations, this process of projects of building redevelopment is quite complex. It takes considerable efforts and time to accomplish the projects. If a proper and time bound process is not followed, or if the risks, uncertainties and challenges are not handled properly, even a seemingly simple project can fail, thereby causing great anguish and hardship to the stakeholders. Sometimes this may lead to prolonged litigation. There is a need to identify risks and challenges involved in the process of building redevelopment projects. The aim of researchers is to interact with all the stakeholders of building development projects of housing societies and identify various risks and challenges visa-a-vis gains. The study has also revealed various pitfalls and uncertainties related to these projects. This will enable concerned stakeholders to prepare to address these.

Testo completoAbstract (sommario):
The stakeholder network in a building project can influence the process of adopting sustainable building practice. Complexity of construction projects calls for integrated modes of collaboration, while the excess inertia among stakeholders resulted in sluggish adoption of sustainable design and technologies. This study examined buildings that both had and had not adopted Leadership in Energy and Environmental Design and/or ENERGY STAR in the New York metropolitan area, built, or went through major renovation between 1998 and 2013. Secondary datasets from multiple sources, including a private building database company, US Green Building Council, and the US Environmental Protection Agency, were combined based on building address and used for analysis. Stakeholders involved in those projects were retrospectively identified to understand the diffusion of innovation. The analysis included a total of 205 projects and 273 organizations. Findings suggest that having an architect who had worked on ENERGY STAR project(s) increased the likelihood of adopting ENERGY STAR. However, stakeholders' previous work collaboration was not associated with the adoption of sustainable programs. The method of utilizing multiple secondary datasets was tested to contribute to the methodology of building research by enabling the accumulation of knowledge.

Testo completoAbstract (sommario):
Researchers have explored Building Information Modeling (BIM) utilization on complex buildings. However, limited research has been conducted investigating BIM implementation on simple projects. This study explored the perceptions of Architects, General Contractors and Owners regarding the project characteristics that impact successful BIM implementation, and the realized benefits thereof, on complex commercial buildings versus parking garages. A survey comprised of the project characteristics and realized benefits of BIM implementation identified by Dodge Data & Analytics was distributed. Exploratory Factor Analysis was conducted to identify the empirical groupings of successful BIM implementation characteristics and realized benefits thereof. Factor means were calculated and compared using ANOVA and t-tests. Statistical comparisons revealed no significant differences by building type. For project stakeholders, a significant difference was only observed on owner’s mean perceptions of technology-related characteristics when compared to architects. Previous research indicates that Architecture, Engineering, and Construction (AEC) stakeholders believe BIM is beneficial for large and complex projects. With the exception of technology-related project characteristics, findings reveal no statistical differences for project characteristics impacting successful BIM utilization or the realized benefits of BIM implementation given building type. This finding provides empirical evidence that various stakeholder groups view BIM as a universal AEC process that provides benefits on both complex and simple projects.

Testo completoAbstract (sommario):
Implementation of the building construction projects is done by workers with diverse knowledge. The knowledge diversity can either be beneficial or detrimental to the implementation process. Out of the 50 building construction projects implemented by Kajiado county government in the financial year 2016/2017, 24 were not successfully implemented. This study sought to determine the influence of project team knowledge diversity on the implementation of building construction projects. The study used a pragmatism paradigm as well as a correlational research design and a sample of 251 respondents. Data was collected using semi-structured questionnaires, interview guides, and observation. Quantitative data was analysed for means and standard deviation as well as inferential techniques for correlation and regression while hypothesis was tested using ANOVA. Qualitative data was thematically analysed and the results triangulated with the quantitative results for presentation. The results indicated the existence of a positive correlation (r=0.323) between project team knowledge diversity and implementation of building construction projects. It was also established that 10.4% of the variations in implementation of the building construction projects are attributable to project team knowledge diversity R2=0.104 . The null hypothesis project team knowledge diversity has no significant influence on implementation of building construction projects was rejected based on F1,219=25.522, p=0.0000<0.05. It was concluded that project team knowledge diversity has a significant influence on implementation of building construction projects. The study recommends that recruitment into project teams for implementation of building construction projects should consider people with diverse knowledge backgrounds since they complement each other’s competencies.

Purpose Literature on organizational analysis identified that project participants have a certain impact on the project outcome. However, there is no study that identifies the impact of project teams and individual project participants on a green building project. The purpose of this paper is to analyze the impact of green building project teams on green building certification. Design/methodology/approach Project information, project team information, and green building certification grade were collected using the Canadian green building database. Project team data were analyzed and organizations were ranked based on their green building project experience and collaborations with experienced green building organizations. The page rank algorithm is used to calculate the rank of organizations in order to identify the impact of organizational rank on the final green building certification grade of a project. Findings The results show a positive relationship between the green building certification grade and the number of organizations with more green building experience in a project team. The results also show that not having experienced key organizations such as owners, designers, and contractors will likely lead to a lower green building certification grade. Originality/value Impact of project teams on green building projects has not been studied before. This study used an innovative method to analyze green building project teams and to investigate the importance of green building project experience. The findings of this study provided evidence to support the influence of project team compositions in green building projects. The results presented in this paper can help project owners and managers during project team formation for successful execution of green building projects.

Testo completoAbstract (sommario):
Research in sustainable building practices suggests that integrated project delivery methods can more successfully deliver green buildings as measured by cost, schedule, and quality objectives. Design-build is an integrated project delivery method that has increased in use in the public sector. Design-build projects are commonly acquired through best-value procurement, which includes factors in addition to price. However, the procurement process of green buildings requires specific selection factors that are not accounted for in conventional buildings. This study synthesizes the current state of practice for best-value procurement of sustainable design-build projects within the public sector. The findings are based upon a content analysis of procurement documents for 26 projects. The results of this study reveal that procurement opportunities exist to improve best-value award algorithms. The findings show that owners are missing opportunities to evaluate design-builders on sustainable building experience and sustainability of the proposed design in project management plans. Modifying the solicitation documents to include these elements could improve the overall success of delivery.

Purpose Despite their energy conservation potential, still existing buildings are slow in embracing building energy efficiency retrofits (BEER), mainly because of the absence of a clearly defined process to deliver the BEER projects, and the lack of proactive guidance for project teams. Further, the identification of factors that can facilitate BEER projects is also important to ensure the project success. This is particularly true in energy service company (ESCO)-led projects. Hence, this study aims at investigating the decision-making process, including the motivators for the successful execution of each stage in implementing BEER when projects are outsourced to a third party. Design/methodology/approach An in-depth case study was carried out to investigate the decision-making process and motivators in implementing BEER in a selected hotel building. Seven semi-structured interviews were conducted to collect the required data within the case. Findings Study disclosed the 13 key decisions made and 37 key activities performed in each stage of the project. A total of 19 motivators for the successful execution of the respective stages were also elicited. Ultimately, the research findings are mapped against the five key stages of BEER decision-making process. Originality/value The outcome of this study will provide the industry practitioners a basis for the effective adoption and implementation of BEER in existing hotel buildings when an external contractor is involved.

Abandoned buildings which are exposed to weather and human threat may lead to deterioration in building quality. Indirectly, the buyer is not satisfied when the abandoned buildings is completed and occupied. This study seeks to assess residents' satisfaction towards residential building quality which was abandoned. This research combined quantitative and qualitative methods. Respondents are randomly selected based on reports and information obtained through the Ministry Housing and Local Government (MHLG) and Local Authority (LA). Subsequently thirty (30) housing projects were selected to answer the questionnaires. Based on thirty (30) housing projects which have been completed, only three (3) housing projects ranged between six (6) months to two (2) years and have been occupied by the buyers. A total of ten (10) developers were interviewed with respect to rehabilitation of abandoned projects. Thus 194 respondents were randomly selected to achieve the objective of the study. The data was analysed through descriptive statistical analysis and inferential statistics. This research demonstrated that abandoned housing project can lead to residents' satisfaction towards building quality. In order to rehabilitate abandoned housing, the study subsequently suggested build then sell approach towards achieving better housing quality.

The need for continuous global improvement in the construction industry’s current state is inevitable. This pursuit for advancement is to benefit all concerned stakeholders in the construction industry, and innovation has been acknowledged as this improvement measure. Interestingly, Building Information Model (BIM) is a typical example of such innovation in the construction industry. It circumvents human errors, lessening project costs, strengthening productivity and quality, and reducing the project delivery time. This analysis investigates the factors influencing BIM implementation in construction in developing nations. A comprehensive literature review was performed to determine what factors contribute to BIM adoption. These drivers were categorized using exploratory factor analysis (EFA). Partial Least Square Structural Equation Modeling (PLS-SEM) was also used with a questionnaire survey of 100 Nigerian building engineering professionals. Findings from the model highlight the most critical drivers of sustainable BIM deployment. The study’s conclusion will serve as a guideline for policymakers in developing nations that want to finish successful projects by avoiding BIM implementation drivers and improving the accomplishment of building projects via the usage of BIM.

Building information modelling (BIM) is a system that integrates multi-dimensional aspects of construction project at every phase. Simply said BIM unified all project databases from and to all stakeholders. This system still continuously developed and widely spread on each countries construction projects. In architecture, the BIM has been revolute the human resource requirements on the projects. Indonesia as developing country is still performing transitions from large worker project into more compact projects; from centralized projects into decentralized project. The BIM system has been a mandatory in several Indonesia big infrastructure projects to plan, simulate, design and deliver databases for making more quick decision making and improve the facilities. This paper aim is describing the benefit-challenge factors of BIM adoption on Indonesia architecture projects and the potential driving factors of BIM application. This study was qualitative paradigm with analysis method of selected literatures and previous research paper review which stratified by the cases. The results of this study are BIM bring the high efficiency and represent the complete skills for an architect. However the high initial cost of technology and human investment, the unsupported regulation and conventional system resistant challenged the Indonesia architecture society to adopt BIM. Furthermore the Indonesia architecture education is still struggling to learn and teach the BIM as an integral part in studio as the agent of change.

There are problems of project abandonment, delays, disputes among the participants in the construction projects, difference between the tender cost, and initial cost and construction cost in most public building projects as a result of inflation and cost overrun in Nigeria. The aim of this study is to examine the influence of inflation and cost overrun on public sector projects in Nigeria and proffer solution on ways to minimize the problems associated with these two variables impacting public sector construction projects. This research work adopted a quantitative research method. This involved design of questionnaires and also collection of secondary data. Fifty questionnaires were administered to public sector professionals and data on ten public buildings projects were collected in Lagos State. The major finding from this study is that inflation and cost overrun affect most public building projects in Lagos State.
