Thesis submitted in fulfilment of the requirements for the degree of Master of Technology: Construction Management Department of Construction Management and Quantity Surveying in the Faculty of Engineering at the Cape Peninsula University of Technology 2015 / This study examines factors contributing to the successful mentorship of women in the South African construction industry. Mentorship is used as a tool to advance women in organisations, because they have experienced difficulties progressing in their careers in the past. Even though women are in mentorship programmes, they still receive less mentorship functions than their counterparts. As a result, women have limited advancement in the construction industry due to factors affecting their successful mentorship. This study identifies and examines the factors contributing to the successful mentorship of women. The objectives of this study were to: (1) test the extent of the influence that the psychosocial mentoring function has on the successful mentorship of women; (2) test the extent of the influence of the career mentoring function on the successful mentorship of women; (3) determine whether the age, gender and race of the mentor-mentee have an impact on the successful mentorship of women; (4) examine the perception of the impact of the entrepreneurial ability of women on the mentorship programme; and (5) to determine whether the mentorship of female mentees is affected by the attitudes of mentors. An in-depth pilot study was carried out during the initial stages of the study to gain more insight about the study. Data was collected by means of semi-structured interviews from female mentees in the Western Cape Province. Data was analysed by content analysis. Findings revealed that the gender and the race of mentors did not have an impact on the success of the female mentees’ mentorship. The age of mentors did impact on knowledge gain. Female mentees reported having open and positive relationships with their mentors. A survey study approach was adopted in the main study. A purposive sampling of female mentees and their mentors was selected. Data was gathered in South Africa. Inferential and descriptive statistics were used to analyse the data. Findings revealed that the psychosocial mentoring characteristics and career mentoring characteristics that influence the successful mentorship of women are role modelling, counselling, acceptance-and-confirmation, coaching and providing challenging tasks. It also emerged that the age and race of female mentees did not have an influence on the successful mentorship of women and that the successful mentorship of women is not affected by the attitude of mentors. It was found that mentors have positive attitudes towards the mentorship of women and that this is contributing positively to the successful mentorship of women in the South African construction industry. The study also revealed that female mentees are high performers, whose knowledge and productivity has increased in the work place. The study therefore concludes that the mentorship of female mentees in the construction industry is successful. It is recommended that females in the construction industry should register themselves to mentorship organisations such as SAWIC, especially those who are not mentored.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Construction Management in the Faculty of Engineering at the Cape Peninsula University of Technology 2014 / The 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.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Design in the Faculty of Informatics and Design at Cape Peninsula University of Technology / This study highlights the preliminary findings of an investigation into ergonomic considerations in the design of women’s protective clothing. The study investigates the validity of an assumption that there is a dearth in the product offerings of women’s protective wear that are ergonomically designed with a good fit, and offer acceptable levels of comfort for women performing outdoors in the construction industry. The research employs a qualitative research method – including interviews with key actors such as women working in the construction industry, and manufacturers. Pertinent psychological and physiological factors relating to the current protective wear are also interrogated herein. For example, the unique morphological features associated with steatopygia and gynaeoid body types are common in the sub-region, and yet not fully accommodated in the design of contextresponsive work wear. The prevailing attitudes among selected manufacturers and suppliers to motivate them to offer superior products for women in the construction industry are explored. A higher adoption rate of the redesigned women’s protective wear could correlate to reductions in downtime associated with general occupational health and safety issues; as well as an impact of low levels of comfort, protection and garment fit. Similarly, the redesigned garments could inform the development of improved protective wear for women, and ultimately facilitate higher productivity in the work environment. Subsequently, a boosted self-confidence and higher levels of motivation occasioned by a positive body image of women workers would validate the efficacy of the intended ergonomic design intervention. Lastly, the thesis discusses sociotechnical strategies for generating high fidelity data for applications in new product development for women’s protective wear. Furthermore, the findings and recommendations are discussed herein; this is made possible by the data collected.

Thesis (MTech (Construction Management))--Cape Peninsula University of Technology, 2015. / Urbanisation and globalisation are the foremost trends propelling the growth and development of cities and towns in the world today. The Cape Town central business district is an example of an urban centre that is required to deal with rapid urbanisation. The increasing number of inner-city developments evoked the congested construction sites and are rapidly becoming the norm within the industry. Innovative building production management is crucial in driving productivity which includes reducing cost at all stages, from planning to completion. However, from several literatures, construction firms are not significantly proactive towards innovative technology that could enhance the efficient delivery of building production. The improved building production management is advancing at a slow pace both in South Africa and internationally. Hence, this research analyse the strategies that could significantly enhance current building production processes and establish the effective management systems that could enhance efficient building production in the urban centres. Innovative methods of stimulating building production processes are needed to ensure that building projects are completed within timeframes and budgets. The research method is both quantitative and qualitative using surveys for data collection. This type of research aims to record an accurate and adequate description of the problem statement and the sub-question. Data for the study are collected through observations, semi-structured and unstructured qualitative interviews and quantitative close-ended questionnaires administered to construction stakeholders working in the Western Cape Province, South Africa. This research focuses on the City of Cape Town to gain an understanding of the dynamics of innovation in building production processes within the building industry. The population of this research include building project managers, registered contractors as well as consultants. Quantitative data obtained from the structured questionnaire design was analysed with descriptive statistics, Statistical Package for Social Science (SPSS) software 21 and content analysis are used to analyse the qualitative data obtained through interviewees.

While wastage of materials has become a serious problem requiring urgent attention in the Nigerian Construction Industry, cost overrun is a problem, which affects 90 percent of the completed projects in the world; the argument on how to reduce/eliminate cost overrun has been on-going for the past 70 years; as the on-site wastage of materials leads to increases in the final project cost. Studies from different parts of the world have shown that construction-material waste represents a relatively large percentage of the production costs. Consequently, as a result of low levels of awareness, the Nigerian construction industry pays little attention to the effects of generated material waste on cost overruns. Thus, this research aimed to investigate the relationship between material waste and cost overrun in the Nigerian construction industry. A comprehensive review of the related literature revealed that all material waste causes are related to cost overrun causes at both pre-contract and post-contract stages of a project; but not vice versa. The mixed method (quantitative and qualitative) approach that is rooted in the positivist paradigm was adopted for this study. Abuja, the federal capital territory of Nigeria was the selected geographical scope of this research, out of which thirty-one (31) construction projects were purposeful selected (projects to the value of 100 million Rand/1.6 billion Naira and above).The research instrument was an interview guide used in conjunction with a tick box. Other sources of data included field investigation (measurement of onsite material waste) and the collection of archival records from bills of quantities, project records, and specifications. Analyses of the findings lead to the conclusion that a relationship exists between material waste and cost overrun; at the pre-contract and at the post-contract stages of a project. The implication is that an increase in material wastage on-site leads to a corresponding increase in the amount of cost overrun, regardless of the percentage allowance for material waste in the process of bill preparation. The study also concluded that the average percentage contribution of material waste to project-cost overruns is four (4) percent. Material-waste sources, causes, and control measures were found to have significant effects (very high, high, medium, low, and very low), in causing or minimising cost overruns at both pre-contract and post-contract stages of projects. The research has developed a conceptual model for the management of material waste and cost overruns in the construction industry based on the results and informed by the theoretical framework. The research has also developed a mathematical model for quantifying the amount of material waste to be generated by a project; as well as a mathematical equation for the effective management of material waste and cost overrun for projects. The study has achieved its aim of establishing an understanding of the issues leading to the relationship between material waste and cost overruns, as well as their management in the Nigerian construction industry. The study recommends that the management of material waste and cost overrun should be revised, based on the findings of this research and included as part of the procurement process. The mathematical models for quantification of onsite material waste, and the mathematical equation for managing material waste and cost overruns developed in the study, could be usefully adopted to improve management of material waste and cost overrun in the Nigerian construction industry.

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.

Construction Planning will increasingly play a more critical role within the realm of the Built Environment. Existing practices used to plan and communicate the construction process to be undertaken are failing to deliver the desired results for construction companies and clients alike. At a time of unprecedented growth in the industry around the world, which is leading to a general skills shortage, especially in management positions, construction planners are increasingly being asked to deal with more responsibility. As with other industries, technological improvement in the tools at their disposal is one way to address the inadequacies of the present situation. Increasingly, three dimensional design packages are being used to generate construction information which can then be used for quantities calculations, automated manufacturing processes and construction simulation. The latter forms the basis for their use in the process of planning, through new technologies being developed as virtual construction tools or 4D planning, the addition of time to the 3D model environment, but using the elements within the model as the basis for the construction programme. The benefit of using the design information to form the basis of the programme is that the interface tasks and logistical activities, as well as location related constraints, can be identified and then communicated to all levels within the construction team through a time based visual image. The purpose of this study is therefore to establish a scientifically analysed alternative method for the creation, review and delivery of construction programmes. In order to achieve the research objectives, three methodologies have been employed. Firstly, the literature review in the fields of planning including existing methodologies and previous research of 4D related techniques has been analysed. An overview of the perceived weaknesses to current practises and proposed solution will be explored and best case scenarios outlined and further investigated. Secondly, the 51 Lime Street project provides an environment in which the proposed 4D planning techniques have been implemented and the benefits of the process can, through observation / participation methodology, be validated. Thirdly, through interview questionnaires, with Lime St contractors and management, and e-mail questionnaires to a broader sample stratum, data on the ability of the tools, the techniques employed on 51 Lime Street and similar projects have been collated and statistically analysed to validate the reliability and relevance for future implementation. The result of the research will provide management teams with a practical alternative to existing planning methodologies. Construction planners will have alternative technique that can further enhance their role within the project team whilst increasing their ability to communicate the team’s vision to a wider audience, making them and the project more efficient and effective in the process. It has been proposed that clients insist on the use of 3D from the commencement of the design process so that this information can be passed downstream through the construction process and onto facilities management. Planners need to be able to communicate their requirements better and the 4D planning models provide both a more inclusive way of planning alongside a better communications medium in the form of moving images. A picture tells a thousand words.

The construction industry remains a pillar in the South African economy, generating employment and wealth. Nonetheless, the industry is reportedly bedevilled by a high rate of accidents and serious injuries that often lead to permanent deformation and fatalities among workers and the general public. These accidents and injuries manifest due to poor construction health and safety (H&S) performance that is often related to poor H&S leadership of the key project leaders involved in the construction business. Shortcomings pertain to client leadership in terms of involvement and commitment to H&S and project H&S related decisions of professionals (designers, project managers, quantity surveyors and engineers). They also pertain to contractor related aspects such as H&S management systems and leadership at all levels of management. In addition, contractors’ inadequacies of H&S management relative to workplace planning and materials related issues have continued to marginalise H&S performance in construction. The H&S leadership of key project leaders is very important in creating a culture of H&S in the workplace. This study examined the H&S management practices and leadership of the key project leaders that contribute to at-risk work practices or unsafe behaviour of workers. Presently, there is limited or no research in South African construction on how the H&S leadership of the key project leaders contributes to at-risk work practices or unsafe behaviour of workers. The methodology employed in the study included an extensive review of relevant literature, which enabled the field work to proceed unhindered. The quantitative survey and qualitative inquiry was conducted with the key construction participants in South African construction. Focus group discussions and interviews were used in a complementary manner. Accordingly, the sampling technique for the study comprised simple random and purposive sampling. The study revealed apparent poor leadership and lack of involvement and commitment to workers’ H&S by the key project leaders. Notably, there is statistical evidence of poor H&S management practices among contractors in terms of top management commitment to and involvement in project H&S. This statistical evidence includes poor H&S education and training of workers and lack of workers’ involvement and participation in H&S matters, which is the tenet of behaviour-based H&S anagement. The model of leadership influence on worker H&S behaviour developed in this research constitutes an innovative contribution to construction H&S performance improvement through a leadership-focused approach. The study has established a basic level of awareness and understanding among key project leaders in that their upstream decisions during the project planning and construction phases have significant influence on workers’ safe or unsafe behaviour or at-risk work practices. The study strongly advocates transparent leadership, ethical behaviour among clients in public and private sectors, designers’ critical H&S decisions, project managers’ and quantity surveyors’ commitment towards project H&S and contractors’ adoption and implementation of behaviour-based H&S management systems. The developed leadership influence model of worker H&S behaviour in the study provides a useful guide for the key project leaders to realise the desired H&S performance improvement in the South African construction industry.

D.Phil. (Engineering Management) / The construction industry has been recognised internationally as one of the most dangerous industries in which to work, with the statistics often explained in terms of the industry’s inherently hazardous nature. In Botswana a total of 281 fatalities were reported to government agencies, mainly recorded in the high-risk sectors over the period of 2000-2004. The purpose of this study was to investigate the role played by key stakeholders in the health and safety (H&S) performance of the Botswana construction industry and to evaluate their level of H&S commitment and implementation. The aim was to determine how clients, designers and contractors can successfully contribute to H&S performance. Five objectives were identified in this research study. The first was to examine the role of key stakeholders in minimising H&S accidents and incidents in the overall H&S performance of the construction industry of Botswana. The second was to establish whether relevant health and safety planning measures contribute to health and safety performance of the construction industry in Botswana. Thirdly, it was to investigate the extent to which the existing legislative framework is relevant to health and safety performance in the construction industry. The fourth was to determine health and safety commitment levels of clients, designers and contractors’ top management in the construction industry of Botswana. The final objective was to design a multi-stakeholder consultative framework that would address H&S from inception to implementation of the construction project. These objectives were achieved through a research design which included a literature review, methods used and procedures developed to administer the questionnaires, data-collection and analysis through various statistical methods. These included descriptive statistics and nonparametric inferential statistics. The results are then presented in statistical format, tables and graphs. While the literature review revealed that construction industry H&S in developed nations is driven by legislation and regulations, the analysis indicated that there is neither statutory obligation nor the desire on the part of designers and the clients to consider H&S...

D.Ing. / The construction industry has changed dramatically over the past thirty odd years. The following factors played a significant role in this change: (1) The building boom around the 1970s pressurized the industry to work faster. This was followed by periods of variation in workload, which have over the last number of years manifested in a permanent low demand for construction in South Africa. (2) Projects became larger and more complex. (3) An over-regulated labour environment not only leads to the downsize of organizations, but is a main contributor towards the increased use of subcontracting. (4) The time value of money causes owners to specify compressed project schedules and lowest price is often the only selection factor in the award of contracts. The shift in work from predominantly public sector towards the private sector, which by nature is more time conscious, is another factor pressurizing the industry to work faster. The industry has introduced amongst others the following measures to cope with these demands: (1) Main contractors are subcontracting more and more of the work. (2) The traditional in-series concept came under pressure - the management approaches became formal procurement concepts and design-build re-appeared. (3) New construction techniques such as fast-tracking and the movement towards factory produced elements in certain areas, for example precast concrete elements, reduced project schedules and replaced previously time consuming activities and counteracted to a certain extent the shortage of skilled tradesmen. The author argues that in the process to combat these external pressures, the following problems, amongst others, manifested: (1) Ineffective project procurement. (2) Unethical and unsound practices between main contractors and subcontractors. (3) Lack of quality and reliability of a substantial share of end-products. Another problem burdening the industry is historical, namely cultural differences between designers and contractors.
