Texte intégralRésumé :
Purpose – A large number of benefits have been reported when reverse logistics (RL) is fully implemented in the construction industry. However, RL is yet to become common place in the construction sector, particularly in Australia. The particular sub-sector in which RL operates is small and weak and the remainder of the sector must embrace and accommodate it comfortably. Research is lacking on how to promoting RL in the construction industry. Very little has been done to identify the current practices that have the potential to promote RL industry-wide. The purpose of this paper is to identify the practices that work well in the sector, a strategy could be mapped out to promote RL to all stakeholders. Design/methodology/approach – In order to fill the above gap, the present study used a mixed method approach to gather and evaluate current practices and their potential to promote RL in South Australia’s construction industry. Practices that were identified using a comprehensive literature review were evaluated with a questionnaire survey and series of interviews involving construction professionals. Findings – The findings are that practices facilitating deconstruction is the most important, followed by practices facilitating the use of salvaged materials in new construction to promote RL in South Australia. Awareness of deconstruction benefits, challenges and procedures at the organisation level and facilities and services at industry level were associated with RL implementation. Availability of salvaged materials in the market was found to influence its use in new construction and as a consequence its demand. Designing for reverse logistics is another practice that could facilitate deconstruction and the onus of its promotion lies mainly with the designers. Research limitations/implications – This research was confined to one state in Australia. As such the generalisation to other states and other countries should be treated cautiously. Practical implications – The findings of this study can help inform the industry and its stakeholders on areas that they need to concentrate more on to make the South Australian construction industry a fully RL integrated one. To that end the authors propose some recommendations arising from the findings reported here. Originality/value – This study makes a contribution to the body of knowledge on reserve logistics within a previously unexplored South Australian context. In addition, the study provides valuable insights into the contribution of RL practices to the construction industry.

AbstractOriginally presented at the National Injury Management and Prevention Conference: Transition and Change, on April 27, 2006, which was held at the Hyatt Regency, Adelaide, South Australia. Reprinted with the permission of the authors.Work in the Australian construction industry is fraught with risk and the potential for serious harm. The industry is consistently placed within the three most hazardous industries to work along with other industries such as mining and transport (National Occupational Health and Safety Commission, 2003). In the 2001 to 2002 period, construction work killed 39 people and injured 13,250 more. Hence, more effort is required to reduce the injury rate and maximise the value of the rehabilitation/back-to-work process.

Texte intégralRésumé :
Collaboration in decommissioning offshore infrastructure could save both industry and taxpayers billions of dollars and facilitate new industries and exports for Australia, especially in the Asia-Pacific region. At the end of the liquefied natural gas (LNG) plant construction boom, Australia must not miss out on this major new opportunity. The 2017 bid for Commonwealth funding to establish a Decommissioning Offshore Infrastructure Cooperative Research Centre (DOI-CRC) involved more than 30 participants and many other collaborators. High-level commitments were made by Chevron, Woodside, Shell, BHP, ExxonMobil, Quadrant, The University of Western Australia, Curtin University, the University of New South Wales, Deakin University, Australian Maritime College, CSIRO and Australian Institute of Marine Science. A Perth-based DOI-CRC was supported by National Energy Resources Australia, National Offshore Petroleum Safety and Environmental Management Authority and other Australian Government bodies and by the Western Australian Government and its Chief Scientist and agencies but did not receive sufficient support from the CRC Advisory Committee. Meeting decommissioning challenges in the North West Shelf, Bass Strait and the Northern Territory in a timely, robust, scientific, efficient and cost-effective manner that contributes to a sustainable marine environment should draw upon and augment international best practice with local capability and expertise. Good science and innovative engineering are needed to support regulatory approval of options such as ‘rigs to reefs’ and commercial opportunities such as in waste management and expanded fishing and tourism. APPEA and operators wish to maintain DOI-CRC’s momentum and learn from UK research arrangements through funding marine science projects. But we must be much broader if we are to build a sustainable world-class Australian decommissioning industry. In particular, we need to work more closely with state and federal regulators and policymakers and undertake more engineering science research and innovation.

Texte intégralRésumé :
Purpose – Understanding and simulating construction activities is a vital issue from a macro-perspective, since construction is an important contributor in economic development. Although the construction labor productivity frontier has attracted much research effort, the temporal and regional characteristics have not yet been explored. The purpose of this paper is to investigate the long-run equilibrium and dynamics within construction development under a conditional frontier context. Design/methodology/approach – Analogous to the simplified production function, this research adopts the conditional frontier theory to investigate the convergence of construction labor productivity across regions and over time. Error correction models are implemented to identify the long-run equilibrium and dynamics of construction labor productivity against three types of convergence hypotheses, while a panel regression method is used to capture the regional heterogeneity. The developed models are applied to investigate and simulate the construction labor productivity in the Australian states and territories. Findings – The results suggest that construction labor productivity in Australia should converge to stable frontiers in a long-run perspective. The dynamics of the productivity are mainly caused by the technology utilization efficiency levels of the local construction industry, while the influences of changes in technology level and capital depending appear limited. Five regional clusters of the Australian construction labor productivity are suggested by the simulation results, including New South Wales; Australian Capital Territory; Northern Territory, Queensland, and Western Australia; South Australia; and Tasmania and Victoria. Originality/value – Three types of frontier of construction labor productivity is proposed. An econometric approach is developed to identify the convergence frontier of construction labor productivity across regions over time. The specified model can provides accurate predictions of the construction labor productivity.

Texte intégralRésumé :
Purpose – A research study has been undertaken at the University of South Australia to introduce application of lessons learned process in construction contractors ' bidding process in the context of knowledge management. The study aims to identify barriers to effectively capture lessons learned in Australian construction industry and how knowledge management can benefit from lessons learned application. Design/methodology/approach – The research study has been undertaken through conducting a “methodological triangulation” and “interdisciplinary triangulation”. This involved an extensive literature review of knowledge management, organisation learning, lessons learned and associated processes and administration of a questionnaire to a sample of construction contractors operating in Australia to elicit opinions on the main barriers to capturing lessons learned, practices such as existence and retention of documentation procedures. A total of 81 useable responses were received from 450 organisations. Response data were subjected to descriptive and inferential statistics with correlation analysis to examine the strength of relationship among the barriers. Findings – The top-3 barriers to the effective capturing of lessons learned were “lack of employee time”, “lack of resources” and “lack of clear guidelines”, whereas, “lack of management support” was the least ranked barrier. The study established that despite the majority of the ACCs having formal procedures for recording the tenders submitted and their outcomes, only a minority actually retained the lessons learned documentation for each project. The larger contractors were found to be more aware of the importance of lessons learned documentation. A comparative analysis with previous studies also found a disparity in the ranking of the barriers. Research limitations/implications – The majority of the participants were small construction contractors in Australia. The reason is that the researchers were not aware of the contractors ' size prior to inviting them for participation in the research study. Second the findings may not generalize to other industries or to organisations operating in other countries. Originality/value – The findings of this survey help ACCs to understand the importance of lessons learned documentation as part of lessons learned implementation and identify the barriers to effectively document their lessons learned. The study provides insights on the barriers and proposes advocated solutions in form of drivers and enablers (critical success factors) of organisational learning capturing among the Australian construction contractors. By reviewing the current literature, “post-project reviews” and “lessons learned” as important elements of organisation learning knowledge transfer, are addressed. Finally, contribution of this study to knowledge and practice has been discussed in this paper.

International Journal of Environmental Research and Public Health 17, no 21 (9 novembre 2020) : 8273. http://dx.doi.org/10.3390/ijerph17218273.
Texte intégralRésumé :
Construction activities involve a lot of risk as workers are exposed to a wide range of job hazards, such as working at height, moving vehicles, toxic substances, and confined spaces. The hazards related to a construction project are mostly unpredictable because construction projects move quickly due to project deadlines, and changing work environments. As a result of this, the industry accounts for one of the highest numbers of work-related claims, and the fourth highest incidence rate of serious claims in Australia. This research investigates how key safety management factors can measure the characteristics of high reliability organisations (HROs) in the construction industry in New South Wales Australia. To address the problem, a model is presented that can predict characteristics of HRO in construction (CHC). Using structural equation modeling (SEM), and confirmatory factor analysis (CFA), the model and measurement instruments are tested and validated from data collected from construction workers. The results identified the factors that effectively measure CHC, and the findings can also be used as a safety management strategy and will contribute to the body of knowledge in research.

Supply Chain Management : An International Journal 20, no 2 (9 mars 2015) : 179–204. http://dx.doi.org/10.1108/scm-10-2014-0325.
Texte intégralRésumé :
Purpose – This paper aims to present a survey of the perceptions of the barriers to implementing reverse logistics (RL) practices in South Australian (SA) construction organisations. Despite the extensive research on forward logistics and RL, there is a paucity of studies that examine the barriers to implementing RL particularly within the Australian construction industry. This study builds on the ongoing research being undertaken by the authors, entitled “Designing for reverse logistics (DfRL) within the building life cycle: practices, drivers and barriers”, which is examining the best practices and drivers that could be used as a “road map” for developing appropriate solutions for the successful implementation of RL. Design/methodology/approach – Data were collected by utilising a triangulated data collection approach, a literature review and 49 questionnaires. The review of the literature identified 16 barriers to implementing RL. The quantitative survey data were subjected to descriptive and inferential statistics with correlation analysis to examine the relationships between different pairs of variables comprising RL’s critical barriers. Findings – The following barriers were indicated as most significant: lack of incorporation of salvaged materials by designers; regulation restrictions to usage of recovered materials and components; potential legal liabilities; higher costs; and longer-time association with deconstructing buildings. The least ranked barriers were mostly drawn from the operational and industrial categories as being: organisational lack of support for deconstruction due to incompatible design; lack of organisational support for deconstructing buildings due to higher health and safety risks; and inadequate skills and experience for deconstruction (operational). The industrial barrier was related to “higher costs of salvaged materials in comparison to virgin products”. Research limitations/implications – First, the reported findings are focussed on one study that used questionnaire surveys within the construction industry; therefore, the results may not be generalisable to other contexts. Further, studies should be conducted and extended to other industrial sectors beyond the construction industry. Second, the quantitative study (n = 49) used a smaller sample, and the survey items were based on the review of the literature. Practical implications – The identified barriers could be used as a “road map” for the development of appropriate solutions for the successful implementation of RL, and to improve the environment-related decision-making processes of contractors. Originality/value – This study makes a contribution to the body of knowledge on the subject of RL within a previously unexplored SA context. In addition, the study provides some insights on the contributory effects of the barriers to the implementation of RL. It is the first work undertaken to determine the barriers to the adoption of RL within the SA construction industry.

Texte intégralRésumé :
After three years of trying, the Coalition Government finally succeeded in obtaining passage of several key workplace reform statutes in 2016. This followed the outcome of the federal election held on 2 July, delivering the Government a differently composed Senate and a new opportunity to secure support for its legislative program. This review article explains key aspects of the industrial legislation passed by federal Parliament in 2016, including statutes abolishing the specialist road transport industry tribunal, re-establishing the Howard-era regulator for the construction industry, and setting up a new agency to enforce enhanced governance and accountability standards for registered unions and employer organisations. Legislative amendments aimed at resolving the long-running bargaining dispute in Victoria’s Country Fire Authority are also considered, along with the Government’s muted response to the 2015 Productivity Commission review of the workplace relations framework. The article then examines developments at state level, including a major rewrite of Queensland’s industrial legislation, structural changes in New South Wales, and proposed changes to long service leave and the labour hire sector in Victoria. It concludes by noting the irony that just as the federal Government has tasted some success after a long legislative ‘dry spell’, its labour law reform agenda appears limited and piecemeal.

Texte intégralRésumé :
Purpose – The purpose of this paper is to examine green building legislation requirements and practices in the construction project execution stage within the context of the South African construction industry. The rationale for this examination rests with the perception that the implementation of green practices (per se) has been recognised as being “behind” the legislation enacted to control the design and construction of green buildings. Design/methodology/approach – The research process consisted of a literature review to identify existing green building legislation and practices applicable to the project execution phase. This was supported by a sequential mixed-method research approach, which involved a survey of contracting companies based in the Western Cape Province of South Africa. Purposive sampling was used to undertake focused interviews with management staff and site operatives. Findings – Research findings established a number of issues, not least: a gap between green building practices and legislation requirements; a high degree of unawareness of green building legislation/practices by construction company stakeholders; selective implementation of health and safety legislative requirements; that management staff had a more “positive” attitude to green building practices than site-based staff who tended to be less motivated and open to such practices. Research limitations/implications – Results from this study are considered generalisable with the sample frame only. Research inference and projections should therefore only be made within this set, and not to the wider population of South African contractors (as this study was limited to the Western Cape Province). Practical implications – Implications from this research are applicable to construction company stakeholders within the population set. Practical considerations include the need to acknowledge a formal commitment to developing a sustainable built environment – especially cognisant of the gap between practices on site and green building legislation requirements. Moreover, this lack of awareness in respect of green building practices and legislation requirements impinges upon several wider areas, not least: construction company stakeholders’ positioning, health and safety practices; managerial and operational staff perceptions, and stakeholders’ willingness and motivation to proactively address these gaps. Social implications – Government bodies and allied professionals in charge of construction industry development are encouraged to consider the implementation of green building legislation requirements on construction sites. This reflection should encourage engagement through formative legislative provision and transparent awareness campaigns. Originality/value – This work is original insofar as it directly addresses the alignment of legislation to current practices within the context of the South African construction industry. However, similar exercises have been undertaken on green building legislation in other countries such as USA, UK and Australia.

Texte intégralRésumé :
Purpose The issue of low productivity has remained a very stern and chronic problem in construction projects. Previous studies have found poor communication as one of the leading causes of low-construction productivity. Recent advances in the field of information and communication technologies (ICT) have the potential to enhance communication and access to information in construction projects. However, the implications of the use of mobile ICT on construction productivity have not been investigated in sufficient depth, especially from the perspectives of its users, i.e. construction management (CM) professionals. The paper aims to discuss these issues. Design/methodology/approach A focus group session involving ten experienced CM professionals from different organisations of the South Australian construction industry was moderated by a group of four researchers to gather data on mobile ICT usage and its implications for construction productivity. Findings Lack of training and guidelines on effective applications of these technologies to construction projects is a major bottleneck. Results indicate that despite noticeable advances in mobile ICT, differences in usage style and user attitude have limited their overall impact on productivity. Research limitations/implications This paper is based on data gathered from CM professionals working in the South Australian construction industry. Practical implications The study highlights the importance of strategising the use of mobile ICT to achieve the desired productivity rates through policy, training, work-life balance, and deeper and wider understanding of these technologies. Originality/value The study examines the perceptions of CM professionals on the usefulness of mobile ICT in construction projects and its implications for construction productivity.

Texte intégralRésumé :
The construction industry poses a number of challenges to those working in it. One important challenge is that the industry is dependent upon human interactions in the management of building projects. In this environment it is important for those who manage the projects to deal with intricate relationships and to consider the emotions, interactions and various types of reasoning that lie behind the actions and decisions taken by the participants in the construction process.
The issue for researchers is to gain a better understanding of the variables that affect the actions of the participants in this process. Such research demands sensitivity to the values, attitudes and behavior developed by the different occupational groupings. These factors according to Edgar Schein define the culture of a professional group. This research was conceived on the belief that the professionals in the construction industry brought to bear their own professional culture on the industry. It was necessary to have a better understanding of this culture in order to be able to resolve disputes that occur in the construction process.
That is the impact of culturally deternlined values, attitudes and behavior of these professional groups. Therefore, this research is aimed at investigating the professional cultures of the participants who come together in a construction project. The question posed was whether they shared a culture or had differences, and if differences existed whetherthese differences had an effect on the reactions of each of the groups to disputes and their resolution.
A survey was carried out among professional groups in Australia and Sri-Lanka and the survey data from both countries were analyzed using statistical tests. The results show that professional groups share similarities in professional culture as well as differences. It also showed that these cultural differences created an adversarial atmosphere among construction project participants. It was also found that introducing a party outside of the usual professional groups would be beneficial in the resolution process. Respondents were of the opinion that the third party outside of the construction team could be a lawyer.
This type of research is still new within the field of construction. The contributions of this work are to link professional culture and conflict and give some indication how such conflict could be addressed. In this context by identifying the values attitudes and behavior of professional groups the subject of conflict and disputes could be beneficially addressed through professional education.

In general, dreams are conceived, ideas are conceptualised, and initiatives are embarked upon in order to alter the state of realities. Dreams change realities; when mechanisms are put in place to realise them, dreams succeed. However, anecdotal evidence as well as empirical findings has continued to reiterate the difficulties associated with realising dreams related to construction projects. Extending the „dream‟ analogy to the South African construction industry context therefore paints an uninspiring picture. Dreams associated with construction do not have a 100% chance of becoming realities as evident in reported poor project performance in the industry. Shattered dreams in the form of poor performing projects, poorly implemented construction processes, or worst, projects delivered at the expense of unexpected cost to the client as a direct result of poor H&S or time overruns, negate the intent of dreams. This thesis is primarily concerned with project performance related bottlenecks in South African construction. After an extensive review of related literature that entails the analysis of publications related to non-value adding activities (NVAAs), supply chain management (SCM), and system dynamics (SD) in the construction project management realm, an exhaustive mixed-mode quantitative survey was conducted among key participants in the South African infrastructure sector. Public sector clients, consulting engineers and contractors that were involved in civil engineering projects were surveyed repeatedly with approximately five survey instruments at convenient intervals. Results arising from the study, inter-alia, indicate that: an appreciable amount of NVAAs occur in South African construction; these NVAAs become further compounded when propagated into other value adding activities (VAAs) in the construction process; the identified NVAAs equally perpetrate the menace associated with poor performance to the detriment of the achievement of cost, H&S, quality, and time project targets, and the root cause of these NVAAs that often contribute to poor performance is not far from the much reported „shortage of skills‟ in South Africa. Notable contributions to the body of knowledge include SD models are extendable regardless of the source of their empirical data as evident in the qualitative models proposed in this study; within the SD domain, it is advisable to consider the „competence‟ of individuals assigned to tasks especially in a developing country as this study revealed that human resources issues predominate among the sources of NVAAs that eventuate in a range of poor project performance; the NVAAs that occur, and their causes on projects are perceived to be due to lapses and / or inadequacies that involved the entire construction supply chain; there is no single construction process / task that is immune from being affected by NVAAs; and within the South African, and by implication construction context generally iii in developing countries, the adequacy of required knowledge among project stakeholders is the most crucial determinant of project performance. As opposed to what is obtainable in developed countries, the construction industry in developing countries, particularly in South Africa, should take advantage of knowledge management (KM) techniques such as brainstorming, communities of practices, and face-to-face interactions. These techniques can be driven through appropriate mentorship programmes, industry focused built environment education, and other human resources driven avenues that do not necessarily require substantial investment in technologies, so that to a large extent organisations in the industry can prioritise KM, and thereafter, continually engage in it for future performance improvement. Using inferential statistical methods for hypotheses testing, and SD concepts for creating qualitative models led to a range of recommendations which, inter-alia, propose that halting the tide of NVAAs and poor performance requires the management of both tacit and explicit knowledge gained in construction; and most importantly, it requires the assurance that „competence‟ is the overriding criteria for selecting project partners, and also, for assigning either design or construction related activities to responsible parties involved in project realisation in South Africa. In effect, in order to engender a culture of continuous improvement in South African construction, other considerations should be subservient to „competence‟ in the construction supply chain. Competence must be located among everyone involved in project realisation, that is, enhancing the competence of all involved in project realisation is as good as ensuring performance improvement, which in turn, equates to the acceleration of project delivery in South Africa.

The research emanated from an investigation of GB7, GB8 and GB9 main contractors in the Eastern Cape Province of South Africa. The study was focussed on the strident economic times in the construction industry following the FIFA Soccer World Cup from August 2010 to December 2012. The research was conducted to identify the key strategy or combination of strategies keeping construction entities in operation. The study further investigates the key elements of a successful turnaround strategy as well as the most effective methods in implementing strategies within construction organizations. The research took the form of an empirical quantitative study where a descriptive survey was used to collect data. Structured interviews were held with the target population to collect data in the field. The study established that geographic diversification was the most effective method utilized by main contractors for survival during the study timeframe. The study also found that lowering of profit margins and preliminary and general amounts were most effective methods in the use of turn around strategies. The study finally concluded that effective steps were taken by main contractors in the Eastern Cape to implement corporate strategies within their organizations. Step by step guidance to all employees on new processes was the key element in successful strategic implementation of a strategy within construction organizations. The research conducted contributes to the strategic management competency within the built environment as well as the existing body of knowledge within the construction industry. All members of the construction industry in South Africa involved with strategic level planning of entities would value the study.

Texte intégralRésumé :
Thesis (MBA (Business Management))--University of Stellenbsoch, 2006.ENGLISH ABSTRACT: South Africa's construction industry is emerging from decades of decline into a period of significant growth and opportunity. The industry will need to double its output over the next ten years in order to cope with the infrastructure and housing demands placed on it. The construction industry is also a national asset and South Africa's economic growth depends on the physical infrastructure that is delivered by this industry. This growth trajectory holds out significant opportunity for employment and training to a community that largely suffers from poverty, unemployment and lack of education. This opportunity will only be realised if the role-players in the industry collectively understand and address the challenges of meaningful and sustainable industry growth and efficiency. The study proceeds with a critical look at issues in the construction industry, to identify the industry's inhibiting factors to delivery and to highlight issues contributing to these factors. A SWOT analysis assists in highlighting internal and external characteristics that can be turned into possible solutions. Based on this analysis, action guidelines are identified. Subsequent chapters investigate possible solutions through project management techniques. The first area of research evolves around labour resource management and finds that thoroughly researched resource planning models could provide predictions regarding shortages and performances, and could also assist in the more accurate planning of skills requirements in the design phase of a project. The advantages of multi-skilling can also be beneficial to efforts to overcome current shortages and train a wider base of new entrants. In order to address low production of workers in the industry, morale-boosting investments are suggested that can yield high returns in the form of improved individual performance, higher job-site productivity, as well as cost and time savings to the project. There is strong evidence that a lack of project team integration is a major constraint to its efficient functioning and, inevitably, successful project delivery. Solutions in the next chapter focus on integration strategies to integrate design and construction in a common goal of delivery methods, to streamline workflow and to find synergy in the efforts of team members. The process of benchmarking encourages participation and clear communication of goals and expectations to all project participants. Process mapping assists in understanding how value is added to projects and mapping of business processes identifies how the project meets its customer's requirements. The third section looks at tools and techniques to promote a more economical construction process through improved management initiatives. Lean construction methods are based on traditional manufacturing concepts, but focuses on minimising waste and inventory and streamlining the flow of resources and information. Another technique is the key emphasis on quality assurance and the advancement through all the processes of innovation that needs to be part of an organisation or project strategy. Knowledge management as a further tool and support measure is complex and challenging in the organisational framework of construction projects. Much of the knowledge gained on projects is lost to future projects. All of the project management tools described in this study will benefit greatly from improved knowledge management. The study identifies some applicable tools and techniques that can be implemented to address critical issues of delivery in the construction industry. The continuous effort and commitment required for successful implementation of these measures will ultimately however depend on change agents and management buy-in that goes with organisation renewal.
AFRIKAANSE OPSOMMING: Die konstruksiebedryf in Suid-Afrika beweeg, na dekades van verval, na 'n tydperk van betekenisvolle groei en geleenthede. Die bedryf sal in die volgende tien jaar moet verdubbel om tred te hou met die eise wat gestel gaan word deur die behoefte aan infrastruktuur en behuising. Die konstruksiebedryf is ook 'n nasionale bate en die ekonomiese groei van Suid-Afrika is afhanklik van die fisiese infrastruktuur wat deur die bedryf gelewer word. Hierdie groeitrajek bied betekenisvolle geleenthede vir werkskepping en opleiding aan 'n gemeenskap wat gebuk gaan onder armoede, werkloosheid en gebrek aan onderwys. Hierdie geleenthede sal slegs realiseer as al die rolspelers in die bedryf begryp wat die uitdagings behels en die geleenthede van volgehoue groei en doeltreffendheid aanspreek. Hierdie studie gaan verder met 'n kritiese benadering tot die strydvrae in die konstruksiebedryf en om die beperkende faktore te identifiseer en die aangeleenthede uit te lig. 'n SWOT ontleding is 'n hulpmiddel om die interne en eksterne karaktertrekke, wat tot oplossings kan lei, saam te voeg. Uit hierdie ontleding kan riglyne vir aksie bepaal word en moontlike oplossings in spesifieke areas van navorsing gevind word. Opvolgende hoofstukke sal moontlike oplossings in tegnieke van projekbestuur ondersoek. Die eerste navorsingsgebied ontvou rondom die bestuur van die arbeidsbron. Die bevinding is dat deeglik nagevorsde modelle van beplanning vooruitskattings lewer ten opsigte van leweringstekorte. Dit bring beter beplanning van vaardigheidsbehoeftes in die beplanningsfase van die projek mee. Die voordele van meervoudige vaardighede kan ook voordelig wees in pogings om die huidige tekort te oorbrug en lei 'n breër spektrum van toetreders op. Ten einde die lae produksie van werkers in die industrie aan te spreek, word die uitbou van moraal voorgestel. Dit lewer hoër opbrengste in die vorm van verbeterde individuele prestasie, hoër produktiwiteit in die werkplek, sowel as algehele koste- en tydsbesparings. Daar bestaan sterk aanduidings dat die gebrek aan interpretasie van projekspanne 'n belangrike beperking op die effektiewe werking en die suksesvolle aflewering van 'n projek het. Oplossings in die volgende hoofstuk fokus op die integrasie van strategiee om ontwerp en konstruksie in die gesamentlike mikpunt van leweringsfunksies te integreer, om die werksvloei te verfyn en sinergie in die pogings van spanlede te vind. Die proses van doelstellingsbestuur verhoog deelname. Dit verskaf duidelike mikpunte en lig verwagtinge aan deelnemers uit. Proses-kartering help mee in die proses om waarde toevoeging tot projekte te begryp. Die kartering van sakeprosesse dui aan hoe projekte die behoeftes van kliënte bevredig. Die derde afdeling plaas die blik op tegnieke om tegniese vaardigheid te bevorder deur meer ekonomiese samestelling en verbeterde bestuursinisiatiewe. Skraalkonstruksie ("lean construction") is gegrondves op tradisionele vervaardigingskonsepte. Dit fokus op minimalisering van vermorsing en stroombelyning van voorraadbestuur sowel as die vloei van hulpbronne en inligting. 'n Ander tegniek is die versekering van kwaliteit en vooruitgang deur die genoemde proses van innovering wat deel moet wees van 'n organisasie of projek se strategie. Kennisbestuur is 'n verdere ondersteuningsmeganisme. Dit is kompleks en uitdagend in die organisatoriese raamwerk van konstruksie projekte. Baie kennis, wat deur projekte verwerf word, gaan verlore vir projekte van die toekoms. Alle hulpmiddels vir projekbestuur wat in hierdie studie beskryf word kan aansienlik baat vind deur verbeterde kennisbestuur. Hierdie studie identifiseer sekere hulpmiddels wat toegepas kan word. Dit spreek ook kritieke strydvrae oor lewering in die konstruksiebedryf aan. Die voortdurende inspanning en toewyding benodig vir die suksesvolle aanwending van hierdie maatreëls vereis voortdurende deelname en onderskrywing van die topbestuur van organisasies.

Texte intégralRésumé :
Construction delays are a global phenomenon. Factors causing construction delays in construction projects differ from country to country, due to different prevailing conditions. The prevailing conditions that could exert an influence on project delivery time are: political, economic, and physical factors as well as level of technological development; management style, and construction techniques. The construction industry is a major player in the economy, generating both employment and wealth. However, many projects experience extensive delays and thereby exceed initial time and cost estimates. This study aims at determining the causes of delays in project delivery in South Africa; evolving interventions, and developing a model for the delivery of projects on time. Inferential and linear regression statistical tools were used in the analysis of data for the study. The sample population consists of architects, builders, quantity surveyors, structural engineers, and clients, and the metropolitan cities of five provinces constituted the geographical delimitation of the study. The provinces are: Eastern Cape; Free State; Gauteng; KwaZulu-Natal, and Western Cape. The metropolitan cities are: Bloemfontein; Cape Town; Durban; Johannesburg, and Port Elizabeth. Findings which negatively influence project delivery time in South Africa include the following: lack of adequate planning; management style; the lack of constructability reviews of designs; inadequate motivation of workers; economic policies; lack of prompt payment to contractors, and quality of management during design and construction. Recommendations include: (1) The introduction of the following courses in built environment tertiary education � quality management competences; operational planning; design management, and generic management; (2) pre-qualification of suppliers; (3) inclusion of the following in tender documentation � human resource schedule; plant and equipment schedule; quality assurance plan, and work schedule; (4) appointment of materials specialists on a large projects; (5) the model developed should be adopted for use in the South African construction industry for the delivery of projects on time, and (6) the linear regression equation: Y = 13.1159 + 1.1341x or 35.3 percent addition on time for the estimation of project delivery time.

2014The study investigates the predominant factors that adversely affect the efficiency of construction labour in the South African construction industry. There is a significant number of studies on construction labour efficiency and productivity. Nonetheless, construction labour efficiency in developed and developing nations is widely reported to be inadequate, and thus adversely impacts the delivery of construction projects. Adequate utilisation of basic construction resources (construction materials and machinery) is significantly dependent on the efficiency of human assets in the construction industry. Hence, the utilisation of construction resources to achieve project objectives in the construction sector cannot be disconnected from the efficiency of construction employees. As a result, the study identified five objectives directed towards improving the efficiency of employees in the construction industry. The first objective identified construction-related factors affecting construction workers’ efficiency; the second objective highlighted design-related factors reducing the efficiency of construction labour; the third identified the impact of construction resources on construction labour efficiency; and the fourth ascertained the external factors affecting the efficiency of human assets in the construction industry. Finally, the last objective is directed towards developing a framework for improving the efficiency of the South African construction workforce. The research adopted a mixed methodological approach, utilising a quantitative questionnaire completed by construction professionals (architects, quantity surveyors, site engineers, project managers, contract managers and site manager). Due to the high level of awareness of site supervisors on labour performance in construction, the quantitative data obtained from construction professionals was subsequently validated using semi-structured interviews with site supervisors. The research questionnaire was designed to elicit the perceptions of construction professionals on various identified factors affecting construction workers’ efficiency on Gauteng and Western Cape construction sites in South Africa. With the aid of 35 unstructured questionnaire surveys, an exploratory study was undertaken within construction firms in Cape Town to ensure the validity of research instruments, where the inputs and comments of respondents were duly considered in formulating the questionnaire for the main study. In the main study, two hundred and sixty-five (265) questionnaires were administered via hand-delivered and electronic mail to construction professionals in the Western Cape and Gauteng provinces, South Africa. Sixty-two (62) questionnaires (23.39%) were duly completed, returned and analysed with Statistical Package for the Social Sciences (SPSS) version 22. Cronbach's alpha coefficient reliability test was subsequently conducted on scaled research questions to ensure reliability of the research questionnaire. The findings revealed that the major factors contributing to the shortfall of construction workers’ performance include; missing details in architectural working drawings, the communication ability of site managers, site managers’ coordinating skills, the effect of strikes on construction operations, the planning ability of site managers, slow response of architects to drawing questions, slow response of structural engineers to drawing questions, construction skills of site supervisors and, finally, shortages of construction materials. Improved construction productivity is a product of construction labour efficiency and enables the achievement of construction project objectives. Therefore, an adequate implementation of the framework presented in this study will not only enhance construction labour efficiency and heighten construction productivity during building production process, but will also increase the satisfaction of construction stakeholder on Gauteng and Western Cape construction projects.

Texte intégralRésumé :
Risk management (RM) should be seen as one of the most important functions in the South African built environment. Without the effective management of the risks associated with the industry, the noble vision of a sector that is efficient, profitable, and sustainable cannot be achieved. By embracing tried and tested policies that successfully mitigate risk, industry stakeholders will achieve many project successes, and will outlast any competitors that choose to ignore, or are ignorant of the fact, that the negative impact risk has on projects is inversely proportional to the level of RM employed. Construction Project Management (CPM) practices, realising that there are excellent business opportunities across South Africa’s borders, and faced with a competitive South African market, are engaging with developers and government entities involved in cross border projects in the hope of securing these potentially lucrative African projects. With this move into Africa comes increased uncertainty and risk for these CPM practices, and other project stakeholders. Similarly, CPM practices that have made the strategic decision to remain operational only within South Africa’s borders, are faced with a competitive and complex built environment and industry, made increasingly challenging by a weakening economy, exacerbated by industrial strikes, infrastructure deficiencies and a decrease in industry skill levels. This study reports on Project Managers’ (PMs’) perceptions of project failures and inefficiencies resulting from inadequate RM on projects, including the RM methodologies currently being employed. The study focused on perceptions of PMs who operate within South Africa’s borders, PMs that operate across border into other African countries, as well as PMs who operate exclusively within South Africa’s built environment framework. A study was undertaken incorporating qualitative methodologies via a normative survey. The survey was split into three main phases. Phase one employed the use of a pilot survey executed with the objective of further investigating the main sub-problems to gain more insight into the related issues and challenges. For the pilot survey, PMs were selected based on their engagement in CPM activities within South Africa as well as across South Africa’s borders into other African countries. Phase two of the main survey, with the sample stratum being the Association of Construction Project Managers (ACPM), was aimed at PMs within the ACPM who have engaged, or are engaging, in CPM activities both within South Africa’s borders as well as across South Africa’s borders into other African countries. Phase 3 of the main survey, with the sample stratum being the ACPM, was aimed at PMs within the ACPM who have engaged, or are engaging, in CPM activities within South Africa’s borders only and have not engaged in cross border activities. Survey findings identified the commercial sector and value of the projects undertaken by the practices, the level of risk associated with different client typologies, the link between inadequate RM and project inefficiency and failure, and the importance of RM on projects. Findings also identified that RM methodologies are employed by CPM practices, and that CPM practices generally endeavour to create a culture of risk awareness amongst employees. Further findings indicated that CPM practices may not always understand the risks associated with new industry sectors, regions or countries that they are considering operating within, and that that there is room for improvement regarding the effectiveness of current RM systems. Survey findings also indicated that risk is not always transferred to the correct project stakeholder most suited to managing the risk, and CPM practices are not always able to accurately quantify the costs associated with project risk. Furthermore, it was identified that CPM practices do not always undertaken risk assessments (RAs) at the correct project stage resulting in inadequate risk contingencies allowances, regular risk reviews are not always undertaken for projects, project pre-mortems are seen as valuable tools by CPM practices as a method to reduce future risk, and project post-mortems relative to ‘lessons learnt’ are not always undertaken. Conclusions outline the link between effective RM, project inefficiencies and project failure, as well as the increase or decrease in risk relative to ineffective or effective use of risk identification and management methodologies for time, cost, and quality factors respectively. Conclusions also outline the fact that although CPM practices generally understand the link between RM and project success, they are not always able to fully comprehend the risks associated with new industry sectors, regions or cross border countries. This indicates that without the adequate identification of risk, the RM process or steps that follow the qualitative risk identification process will have little or no value. This is indicative of the requirement for professional associations to consolidate risk data for industry activities with the aim of improving the level of RM industry wide. Recommendations highlight the importance of the compiling of sector specific risk registers, compiled by the South African Council for the Project and Construction Management Professions (SACPCMP) with registered member input, made available to all PMs via the SACPCMPs online database. Further recommendations include: the engendering, by senior management of CPM practices; a healthy ‘risk aware’ culture, by promoting RM practices aligned with best practice methodologies; the implementation of well balanced and formal RM systems throughout the CPM practice, with the aim of achieving effective RM without overburdening PMs with unnecessary documentation or ‘paperwork’; the attendance of risk conferences and workshops by all CPM practices, aimed at specifically identifying challenges that exist with RM and methods that can be employed to improve the status quo; the attendance of formal risk training courses, by all CPM practices, aimed at improving the knowledge base of PMs relative to effective RM, and the appointment of risk professionals, driven by the monetary value and risk levels of the project, to undertake the RM process and unburden PMs from the task, allowing PMs to concentrate on the other project knowledge areas.

Texte intégralRésumé :
A methodology is proposed for constructing a price index that reflects the change in the prices of the goods and services purchased by medical schemes in South Africa. The methodological choices were made taking cognisance of the unique characteristics of the South African medical scheme environment, both in terms of the factors influencing the mix of goods and services purchased by medical schemes, as well as the factors affecting price determination. An example of a pharmaceutical price index was constructed to illustrate the proposed methodology, the results of which are presented. Whilst the proposed methodology provides a base for creating a meaningful and useful medical scheme price index there is considerable further work that needs to be done to refine the methodology.

Texte intégralRésumé :
Much research work has assessed the construction process and discovered that the process is ineffective and besieged with problems. Analysis of these problems has shown that a major part of them are related to the state and workings of the supply chains. Prior research justifies that waste and problems in construction supply chains are extensively present and persistent. This anomaly may be ascribed to the nature of the industry. Horizontal integration that is common place in the construction industry tends to fragment the supply chain, resulting in an unstable production environment occasioned by high unpredictability, much rework, low profits and eventual low level of value creation in the process. Therefore, an increased level of integration of interfaces and processes has been canvassed. The purpose of supply chain management is to achieve the expected increased level of integration of the whole supply chain. Supply chain management is a concept that has flourished in the manufacturing industry through Just in Time production and logistics. Supply chain management represents an autonomous managerial tool, though still largely dominated by logistics. Supply chain management has long been advocated as a means of improving the performance of supply chains in construction. This research study reports on an investigation into the impact of supply chain management on value creation in the South African construction industry. The research discovered that collaborative working is already in the industry and contractors consider supply chain management important for project success. Here construction supply chains were approached from the relationship view point. All issues are encouraged to be viewed and resolved in the supply chain from the relationship perspective.

Texte intégralRésumé :
This chapter report on some of the challenges faced and successes achieved during the construction of the recently completed Department of Environmental Affairs (DEA) headquarters in South Africa. Qualitative interviews where conducts with five (5) professionals which were part of the construction supply chain team that completed the DEA project in South Africa. Findings summary were that the South African construction industry exists in a very dynamic and volatile environment with common challenges as evident in other countries. This challenge, necessitates the use of collaborative means of managing the various phases of the supply chain. It was also found that the use of collaborative models such as Public Private Partnership (PPP) can prove rewarding when stakeholders involved in a project have an understanding of the model and its dynamics. This chapter contributes to the use of PPP collaborative models in construction project delivery in South Africa.

Dans ASME 2003 9th International Conference on Radioactive Waste Management and Environmental Remediation. ASMEDC, 2003. http://dx.doi.org/10.1115/icem2003-4865.
Texte intégralRésumé :
The Environmental Impact Statement (EIS) for the proposed Australian National Repository for low and short-lived intermediate level radioactive waste was submitted to Environment Australia for approval in the summer of 2002 and has subsequently undergone a consultancy phase with comments sought from all relevant stakeholders. The consultancy period is now closed and responses to the comments have been prepared. This paper describes some of the issues relevant to determining the radiological risk associated with the repository to meet the requirements of the EIS. These include a brief description of the three proposed sites, a description of the proposed trench design, an analysis of the radioactive waste inventory, the proposed approach to developing waste acceptance criteria (WAC) and the approach taken to determine radiological risks during the post-institutional control phase. The three potential sites for the repository are located near the Australian Department of Defence site at Woomera, South Australia. One site is inside the Defense site and two are located nearby, but outside of the site perimeter. All have very similar, but not identical, topographical, geological and hydrogeological characteristics. A very simple trench design has been proposed 15 m deep and with 5 m of cover. One possible variant may be the construction of deeper borehole type vaults to dispose of the more active radioactive sources. A breakdown of the current and predicted future inventory will be presented. The current wastes are dominated in terms of volume by some contaminated soils, resulting from experiments to extract U and Th, and by the operational wastes from the HIFAR research reactor at ANSTO. A significant proportion of the radionuclide inventory is associated with small volumes of sources held by industry, medical, research and defence organisations. The proposed WAC will be described. These are based on the current Australian guidelines and best international practice. The preliminary radiological risk assessment considered the post-institutional control phase in detail with some 12 scenarios being assessed. These include the impact of potential climate change in the region. The results from the risk assessment will be presented and discussed. The assessment work is continuing and will support the license application for construction and operation of the site. Please note that this is not the final assessment for the licence application.

Texte intégralRésumé :
<p>Asset managers are faced with the challenge of maintaining concrete structures in coastal environment, within the financial constraints of maintenance budget allocations, such that they remain functionally and structurally safe for the remainder of their design lives. For these reasons concrete remediation is fast becoming an important component of asset management in coastal areas. This research describes remediation techniques and practice currently being employed by prominent public and private organisations responsible for maintaining concrete structures in the Illawarra region (New South Wales, Australia). These common remediation techniques range from conventional restoration, cathodic protection and structural strengthening. The research also considers the underlying factors used to evaluate the effectiveness of these techniques and practices. A model of good practice for concrete remediation in the Illawarra is developed from the literature and industry research undertaken. This model is developed for concrete suffering deterioration caused by the corrosion of steel reinforcement and is aimed to provide intelligent concrete remediation options based on sound principles and industry knowledge.</p>

Texte intégralRésumé :
Today’s nuclear plant operator is challenged to safely operate a complex power plant while prudently managing the business aspects with efficiency. Risk insights provide a ready tool to aid today’s operators in effectively performing both of these sometimes contradictory tasks with a sound basis. While plants possess and maintain Probabilistic Risk Assessment (PRA) models, other regulatory applications are readily available to aid the nuclear operator. Some of these tools include 10CFR 50.69 Risk-informed Categorization and Treatment of Structures, Systems, and Components for Nuclear Power Reactors, Industry Initiative 4(b) Risk Managed Technical Specifications, and Industry Initiative 5(b) Risk-informed Surveillance Test Intervals. This paper will introduce each of these risk-informed tools and will discuss practical applications of these insights at the South Texas Project nuclear power plant. These insights are readily translatable to other nuclear power facilities. 10CFR 50.69 permits a risk-informed categorization of selected structures, systems, and components. For components determined to be Low Safety Significant, many of the current regulatory controls can be reduced while maintaining reasonable confidence that these ‘Low-ranked’ components continue to perform their design functional requirements. South Texas Project was the industry’s proto-type pilot for this effort. Initiative 4(b) is a risk-informed, configuration-based approach to managing Technical Specification allowed out of service times. The limiting, deterministic allowed outage times are replaced with a Configuration Risk Management Program which uses risk threshold values to determine the length of time a Technical Specification piece of equipment can remain out of service. An imposed back-stop of 30 days is used to limit the allowed outage time. This approach was approved for South Texas Project in July 2007, and South Texas Project was the industry pilot plant for this effort. Initiative 5(b) is a risk-informed approach to Technical Specification surveillance test intervals. This approach allows surveillance test intervals to be removed from Tech Specs and placed in an owner-controlled program. Once relocated, a blending of probabilistic and deterministic insights is used to assess proposed extensions of surveillance test intervals. Once implemented, a feedback process is relied upon to validate the acceptability of the revised testing interval. This approach was piloted by the Limerick Nuclear Station, and South Texas Project submitted a request in October 2007 to the NRC to pursue this initiative. The above risk insights have proven very effective at South Texas Project, and could aid other nuclear operators in making well-founded, informed decisions. Risk insights also allow a Station’s limited resources to be focused on those activities and equipment which are of greatest safety significance. These insights are valuable for current licensees, and may be very beneficial to apply toward new nuclear construction.

Texte intégralRésumé :
The meaningful United States regulation of onshore oil and gas field waste/soil commenced in the mid 1980’s in response to a series of state, federal, industry and international initiatives. Most initiatives centered on the design, construction and operation of earthen pits used in the exploration and production of oil and gas (E&P). Prior to this time, earthen pits were constructed as needed by the operator and used in all phases of E&P activity. Chief concerns of the regulators were focused on what had gone into pits historically, what was going into them currently and was the E&P exemption excluding high volume E&P wastes from the Resource Conservation and Recovery Act (RCRA) regulations justified. Several investigations, including the comprehensive field study by the Environmental Protection Agency in 1987, determined E&P wastes are ostensibly non-hazardous. EPA concluded regulation of E&P wastes under RCRA Subtitle C was not necessary. To this day there is no U. S. federal regulatory program with exclusive jurisdiction over exempt E&P wastes. Other studies, primarily industry and academic, focusing on land limiting constituents, management practices and pit closure strategies revealed sodium salts and petroleum hydrocarbon in the form of diesel range organics were the primary limiting constituents. One state, Louisiana, adopted the technical aspects of these studies and developed a comprehensive regulation known as Statewide Order 29-B, which was based on the concept of limiting constituents and defined post closure performance standards. These standards limited salinity, sodicity, total metals and total petroleum hydrocarbon (oil & grease) with values varying with respect to landform, land use and closure technique. Other states have adopted some of the concepts and criteria advanced under 29-B but none are as comprehensive. Obviously there is a need to control what goes into pits and how pits should be closed. The industry would best be served by adopting the concepts and standards set forth in the Louisiana 29-B regulation. A few of the provisions could be changed to make it more palatable to industry without sacrificing the protection afforded human and animal health, safety and the environment. Internationally, particularly countries in South America embraced USEPA protocol for testing characteristically hazardous wastes, but 1) without the framework to handle the relatively large volume of non-hazardous E&P waste generated and 2) no regulations or protocols for on-site waste management. Several operators, although partners with state owned oil companies, on their own volition, applied the concepts and standards under Louisiana’s 29-B to rainforests in South America and rice paddies in Indonesia. Canada and European oil and gas producing countries have developed stringent standards not based on science, which favor costly treatment technologies. Generally, these countries prohibit cost effective on-site waste management and closure techniques. This paper traces the evolution of waste/soil remediation within the United States and internationally. We trace the progress as a function of time; the impetus for regulation; and probable future controls.
