Evaluation of risk management practices in the construction industry in Swaziland.

Ibidapo, Olutope Olamiwale. January 2014 (has links)
M. Tech. Quantity Surveying (Structured) / Risk is a predominant phenomenon and an inherent challenge in the construction industry; the ability to control its occurrence minimises its impact on the operation of the industry and determines the profitability of the construction projects. This research was carried out to examine the project phases during which the construction industries in Swaziland carry out risk management, to identify and examine the methods, tools, procedures for and approaches to risk management. Furthermore, the research intended to identify the criteria for risk sharing amongst parties in the Swaziland Construction industries.

Assessment of mechanisms to manage financial risks in the South African construction industry.

Okumbe, James Ouko. January 2014 (has links)
D. Tech. Civil Engineering / Construction contracts have provisional clauses to control financial risks, but studies have shown that cost overruns are still common, which require the inclusion of additional management techniques to improve cost estimates. The research investigated, analysed and identified the shortcomings that exist within the current mechanisms to manage financial risk. A new risk ranking model that can be used to eliminate construction cost overruns in South Africa was developed. The study sought the views from a variety of construction professionals, based on knowledge and experiences within their own organisations, to explore new mechanisms to limit the risk impact of persistent cost overruns.

A study of public private partnership project success factors and risk management integration in mainland China

Liang, Yanhong, 梁艳红 January 2012 (has links)
To solve the conflict between limited fiscal funds and increasing demands to strengthen infrastructure construction, Public Private Partnership (PPP) was introduced by the Chinese government as an effective approach to make use of private investment to implement infrastructure projects. To provide services or facilities for public use, in PPP, participants pool their skills and resources while at the same time sharing the risks and rewards. The application of PPP could not only ease the government’s financial pressure, but also improve the efficiency of infrastructure construction and ensure the service quality of projects. Although PPP produces these benefits, the complexity and long-term features of PPP projects expose participants to more risks than in traditional projects. Therefore, risk management of participants is critical to the success of PPP projects. As an innovative procurement approach involves a variety of stakeholders over a long time span, it is necessary to investigate how to appraise and recognize PPP project success. In addition, although risk management has attracted much attention, few studies examine the detailed link between various dimensions of risk management and PPP project success. This research therefore intends to fill these two gaps. Compared with countries in the West, PPP was introduced into China relatively recently. A comparative study was employed in this research in order to understand the Chinese situation and to make use of the experience of other countries to critique PPP project performance in Mainland China. In this study, a two-pronged research program—comprising quantitative and qualitative approaches—was used to test and validate the tripartite theoretical model which was set up based on Transaction Cost Economics (TCE), Resource-based View (RBV) and Relational Exchange Theory (RET). In the quantitative study, questionnaire surveys were conducted concurrently in Mainland China and other places. Hierarchical Multiple Regression was used to explore the relationships posited in the research framework. To provide supportive and complementary evidence to the quantitative data, a case study of a PPP project in Mainland China was undertaken. Open-ended interviews and the thematic analysis technique were adopted in the case study. Taken together, the findings indicated that although the facets of risk management significantly affect project success, there are subtle different influences on different stakeholders’ benefits. For example, the uncertainty of social issues and economic issues will affect public partner’s benefits while the uncertainty of political & institutional issues, economic issues and project specific issues are directly influence private partner’s benefits. To maximize their own interests, different stakeholders should pay more attention to the influencing factors that are specifically associated with them. Meanwhile, it is demonstrated that individual efforts on risk management also contribute to the benefits of other stakeholders as well as to the whole industry development. In addition, the comparative study suggests that public partners of PPP projects in Mainland China could refer to the risk management experience of public partners from other countries to make an appropriate risk management commitment and better manage risks. On the other hand, private partners of PPP projects in Mainland China need to pay more attention to the macro-control of the government so as to protect their rights and interests. / published_or_final_version / Real Estate and Construction / Doctoral / Doctor of Philosophy

Risk management practices on public sector construction projects: Case studies in Lesotho

Nketekete, Molefi January 2016 (has links)
Risk management (RM) is a knowledge area in project management (PM). The challenges of project complexity require astute RM. However, RM practices in Lesotho appear to lag behind international trends. Within the sub-Sahara African region, RM incompetence affects timely delivery of public projects owing to PM practices that do not address risks. This study, which adopts a case study approach, unravels the „how and why‟ of contemporary RM practices which are lacking in Lesotho, despite a poor record of project success in the construction industry. Through the reviewed literature and primary data collection, this study investigates three elements in order to determine the level of RM practice within Lesotho public sector construction projects. These elements were the basis of RM, the RM processes, and the peoples‟ perceptions which were essentially centred on the probability of risk and the impact thereof. The results from the study achieved through cross-case synthesis show that the level of RM practice in the Lesotho public sector construction projects is at variance with international practice. The notable gaps in practice include construction professionals who do not know about or who have not practiced project RM. The study thus propose that the Government of Lesotho (GoL) should invest in educating more people in the areas of construction project management or engage professionals with extensive project RM experience. The recommended initiatives should promote professionalism and accountability that are essential for bracing the RM practice in public sector construction projects.

Risk analysis and management systems in South African construction project management practices

Cook, Iain Murray January 2016 (has links)
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.

Designers' perspectives on early contractor involvement as a means to improve the safety performance on construction sites

Mathenge, Njeri Karuga 17 March 2016 (has links)
A Research Report proposal submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Masters of Science (Building) Project Management in Construction. Johannesburg 2015 / The construction industry is one of the major industries in the world and has one of the poorest records in Occupation Health and Safety. In developing countries with improved political and economic stability in recent years, infrastructure developments have significantly increased which has implications for the industry to deliver projects safely. Many designers’ in the construction industry in developed countries believe that contractors have knowledge to offer concerning safety as they have the experiences from different projects and can pin point potentially hazardous risks in the design phase of the project and consequently improve on the Health and Safety and Safety Performance of a project. This research aimed to discover what designers’ in the South African construction industry perceived about the use of ECI in the industry and its effect on the safety performance on construction sites. A review of the literature showed that the designers in the construction industry had various perceptions towards trust and commitment of the contractor towards safety and liability issues among other concerns. Twenty-nine questions were identified, which formed the basis of the quantitative analysis that was undertaken. Five hundred architects, engineers and project managers were identified from the Gauteng Province of South Africa and a questionnaire survey emailed to them. A census sample was used in this research and despite the low response rate (9%) from the participants; the data collected was seen as representative of the population. Analysis of the data collected from this survey revealed that designers believe that the use of ECI in the construction industry may improve the safety performance of the project as well as including contractors earlier in the design phase may be beneficial in enhancing safety during construction. The research also revealed that the designers believe that contractors have knowledge to offer in designing for safety as well as identifying potentially hazardous risks that may elude the designers during the design phase. From the data collected, a number of recommendations were developed to promote the use of ECI in developing countries including a review of policies and guidelines in the construction regulations so as to boost the use of ECI and consequently reduce the number of accidents and fatalities in the industry and as well as improve the overall safety performance of construction sites in South Africa. The overall finding of this research show that the designers in the South African construction industry have a positive attitude towards the use of ECI in the construction industry and are ready to implement it mainly due to the fact that it has a positive impact on the health and safety of workers as well as the overall safety performance of construction sites.

The Zachman Framework applied to construction engineering risk management

03 July 2012 (has links)
M.Ing. / The research is based on the complexity of project management and risk management fields and how applying each field on its own can be problematic. This poses an everyday challenge to project managers when implemented simultaneously and such a problem predominantly exists in the engineering construction field.The challenge faced by project managers is approached throughout the research study by introducing a commonly used six order matrix framework with a high success rate in analysing and dissecting complex fields into small fragments. The framework is known as the Zachman Framework for Enterprise Architecture. However this is only done once a thorough literature review of both project and risk management as well as the limitations of the Zachman Framework have been well documented.Once the Zachman Framework for Construction adaptation is complete, it is then applied to an inner city construction case study. The results of the case study are used to determine if throughout the project lifecycle it has been possible to analyse and implement all project and risk management requirements simultaneously with little or no correction of project constraints.Using a developed integrated risk management tool which graphically tracks aggregate risk( s) in cost and time together with the Zachman Framework for Construction, the case study results reveal that it is possible to increase the ability to simultaneously manage risk and normal activities by concluding that the project constraints (i.e. cost) are accurately estimated and accomplished. In conclusion the research study,discussion and recommendations are made in order to implement all cells within the Zachman Framework for Construction therefore increasing the success of any project and risk management construction field.

Construction risks allocation : optimal risk allocation decision support model

Alsalman, Ali Abdullah 04 July 2013 (has links)
It has been suggested that projects in the construction industry are subject to risks more than other industries. However, there is often little parity in allocation of risks in the construction industry. Usually, project participants allocate risks by aversion where owners tend to shift risks to the primary contractor, who in turn transfers them to the subcontractors. As a result of this, risks are not necessarily allocated/ re-allocated to the party that is best able to manage them efficiently and effectively. Risk allocation can significantly influence the behavior of the project participants and hence affects project schedule, cost and performance. Inappropriate risk allocation has led to adversarial relationships between contracting participants and has consequently increased project cost. The objective of this dissertation is to shed light on the current practices of risk allocation in the construction industry. The dissertation consists of three sections. The first section investigates and evaluates the problems of the current practice of risks allocation and their impacts on project performance. The second section investigates, identifies, and classifies barriers to optimal risk allocation. The third section looks into allocating construction risk from a more cooperative and rational perspective. The goal is to provide the construction industry with a rational decision-making mechanism that will provide an alternative to the current practice of typically allocating risks by aversion. To meet the objectives, structured survey questionnaires for Sections One and Two were used. The first survey found that the current practice of risk allocation has four major problems. These problems include: 1. Dispute, claims and tension leads to adversarial relationships. 2. Competitive relationship leads to aggressive relationships. 3. Subjective pricing of risk leading to higher contingency. 4. Allocation by aversion that leads to misallocation of risks. The second survey found thirteen barriers to optimal risk allocation, which were classified into three main categories: behavioral, technical, and organizational barriers. Lack of an efficient risk allocation mechanism ranks at the top of the identified barriers. These findings were linked, in causal-effects relationships, to formulate an analytic model for the current practice of risk allocation. This dissertation uses the research findings and the rational decision-making process to develop a practical mechanism for optimizing risk allocation. The developed mechanism was then fine-tuned and validated by a Delphi expert panel technique. The developed mechanism should aid construction industry professionals and construction project participants in making rational and economical risk allocation decisions to alleviate the identified above-mentioned problems, overcome the identified barriers, and improve project efficiency by minimizing the negative impacts of the current practice of risk allocation on project cost, schedule and overall project performance. / Graduation date: 2013 / Access restricted to the OSU Community at author's request from Jan. 4, 2013 - July 4, 2013

The costs of construction accidents

Pillay, Kersey Robin January 2014 (has links)
Dissertation submitted in fulfilment of the requirements for the degree Master of Technology: Construction Management Department of the Built Environment in the Faculty of Construction Management and Quantity Surveying at the Cape Peninsula University of Technology 2014 / The construction industry contributes significantly to national economic growth and offers substantial opportunities for job creation; however the industry has continually been plagued by workplace accidents. Moreover, employers may not realize the economic magnitude of workplace injury and ill health arising from construction activities. These accidents represent a considerable economic and social burden to employers, employees and to society as a whole. Despite governments and organisations worldwide maintaining an on-going commitment towards establishing a working environment free of injury and disease, a great deal of construction accidents continues to frequent our society. Given the high rate of construction accidents experienced, employers are not entirely mindful of the actual costs of construction accidents, especially when considering the hidden or indirect costs of accidents. Various safety research efforts have attempted to quantify the true costs of worker injuries, however localised systematic information on cost of construction accidents at work is not readily available from administrative statistical data sources, therefore this study was carried out in order to estimate the costs, like lost workdays or lost income, are clearly visible and can readily be expressed in monetary value; for a large part however, economic consequences of accidents are somewhat hidden. Indirect costs following an accident may be disregarded, damage to the company image is difficult to quantify and pricing human suffering and health damage is subject to discussion. Nevertheless, it is possible to get an adequate insight into the costs of accidents and the potential benefits of accident prevention.

Older construction workers – a study of related injuries, underlying causes and estimated costs

Eppenberger, Marius January 2008 (has links)
The construction workforce in South Africa is one that is ageing. This is a global phenomenon and necessitates research into how the older cohort of the construction work force can be optimally engaged. Optimum worker productivity, high quality products that meet the specifications required, and high levels of occupational safety and health are integral factors in achieving a sustainable workforce. The purpose of the research was to quantify the injury rates among older construction workers as well as to determine the events leading to these injuries, the nature of the injuries and the bodily locations affected. The costs associated with these injuries were investigated to understand whether there were any discernable differences between injuries to older and younger workers. Apart from the literature review, two statistical construction injury databases were analysed. Qualitative questionnaire based interviews were designed to gather information related to older construction workers. Questionnaires were sent to construction site managers to gauge their perceptions of older construction workers. The statistical data was collected from the Western Cape region and was for the period 1998 through 2005 while the interviews and questionnaire data were collected during 2008. xv The potential benefits to industry are a consolidation of injury information relating to older construction workers. This should assist construction managers with developing policies and implementing strategies to prevent or at least minimise injuries and minimise the related costs, with the aim of more effectively utilising their older workers and ultimately achieving a more sustainable construction industry. The study found that older workers sustained less injuries in total compared with younger workers. No discernable variances occurred between younger and older workers when it came to events leading to injuries (causes) and the type/nature of injuries. It was, however, found that for the body parts affected, older workers were more prone to certain injuries. Older workers sustained less severe injuries compared with their younger counterparts but the injuries were more costly. The research findings supported the notion that older workers receive less training than younger workers.
