Despite the numerous advantages that design and build has as a procurement method for construction projects, which have made it the procurement method of choice for construction projects in Europe and North America, not many South African construction companies are making use of it. This study investigates the constraints which are associated with design and build in South Africa. It also seeks to find out how certain performance indicators in construction fare when design and build is used. It then proposes recommendations on how the method can be improved in order to increase its use in South Africa. Data for the study was collected from six major professions in the construction industry including contractors, engineers, quantity surveyors, project owners, project managers and architects in order to give a more balanced view of the problems. Questionnaires, emails and telephonic conversations were methods used to collect the data. Sample t-tests were then conducted on the data using the statistical package, Statistical Analysis Systems (SAS). The results obtained show that there are numerous problems faced in all phases of construction projects when design and build is used as the procurement method of choice in South Africa. Most of the problems are around the issues of inadequate knowledge by project owners in construction, and also the unavailability of manpower to help owners with technical issues. Of the performance indicators investigated, time management and project quality are found to perform poorly. Project owners should deploy their own project managers in the construction process

With the growth experienced in the Building Industry, it is increasingly important to have a contract document that can be used on projects that is reasonably acceptable to all parties concerned. The objective of the research was to determine the effectiveness of the Joint Building Contracts Committee Series 2000 Principal Building Agreement (JBCC 2000 PBA)(Edition 4.1, March 2005) currently used in the Building Industry. The literature reviewed and results of quantitative research amongst contractors formed the basis of this study. The study revealed that the JBCC 2000 PBA is the most favourable contract document used by contractors in the Building Industry. With the inclusion of a range of construction guarantee alternatives in the contract document in lieu of the retention clause, more than half of the respondents have indicated that they are in favour of a retention clause to be included in the contract document as an alternative security option. The study also showed that there are still areas of concern with regards to the difficulty in interpreting and implementing numerous clauses of the document and that amendments were made to the document without legal advice, resulting in disputes. The research further also revealed that developing building contractors experience difficulties in general where the JBCC 2000 PBA is used as contract document on projects. There also seems to be no balance of risk between the employer and contractor in most cases where this contract document is used. The research concluded with proposals on revisions to some clauses to ensure a better contract document that will be acceptable to all contractors in the Building Industry and ultimately to be an internationally acceptable document.

This research focuses on and summarises the methodology followed to demonstrate that the South African construction industry can use the Construction Registers Service, in particular the Register of Contractors, as a tool to measure the competitiveness of Small, Micro and Medium Enterprises (SMMEs). The Register of Contractors (RoC) was developed by the Construction Industry Development Board (cidb) in terms of the Construction Industry Development Board (cidb) Act 38 of 2000. As a tool, it was designed to offer a basis for sustainable constructor development, growth, improved delivery, performance and sustainable empowerment. It was also developed to be used by the construction industry to, inter alia, and provide statistical data which would enable the construction industry to better understand the contracting capacity in South Africa. Beyond providing the statistical data, the register of contractors was meant to be enhanced with functionalities that would measure the growth and performance of contractors as they apply business practices that improve their value offering to the construction industry as a whole. This research looks at how this tool can be used by the construction industry to measure the competitiveness of the contractors within the selected grades, with the intent of demonstrating the overall value of the RoC as a tool. The research undertaken looks at how the use of the RoC can measure the competitiveness of a targeted group of small contractors. The research limits itself to the entry levels of contractors registered with the cidb between grades 2 and 5 with a view to establish a benchmark for contractor competitiveness within those bands. The research further proves the correlation between contractor capability and the ‘ability’ to be competitive in growing their value proposition and businesses. The unit of study for the purposes of this research is at firm level drawing from a reflection on who is an active participant in the South African construction industry particularly as it pertains to the smaller contractors within the targeted group elucidated above. The focus of the research is on the efficacy of the RoC as a tool that identifies the areas needing targeted development to support SMMEs and the subsequent demonstration of improved business processes within that sector. The qualitative research methodology was followed through this study as its nature was such that there was no requirement to rely only entirely on statistics or numbers due to the articulated problem there needed to be a qualitative enquiry into data needed which would adequately land to a significant synthesis on the responses and arrive at suitable solutions to the identified problem. The qualitative research methodology followed by this study was used to gain insight into the construction SMMEs’ attitudes towards the sector within which they trade, their behaviours, their value systems [to the extent where this was possible], their concerns, their motivations and aspirations. All of these, the study concluded that they inform the business decisions which the SMMEs make. How structured information was collected and analysed provided a synthesis of themes and aided in extracting meaning. The main findings of the research were that there is no shared understanding within the local construction industry of what contractor competitiveness is and to what extent it would benefit both the industry and the SMME sector. As a result of this competitiveness could not be measured and there was no clarity as to what tools of measure could be used to forecast the capabilities of the industry. This research was focused on exploring how the RoC can be used to measure improved capability and competitiveness on the part of SMME contractors. The implications of these findings are that there would now be improved and measurable competitiveness allowing the contractors to bid for work both within their provincial regions but also outside of their geographical location and to measure their growth as they achieve higher grading statuses within the register of contractors (RoC). The efficacy of contractor development programmes would also improve as they go beyond enhancing contractor capacity but also include competence improvements, training for business acumen, improved capability and innovation. The conclusion is that South Africa’s construction industry could achieve sustainable development and growth as a result of SMME contractors whose competitiveness would have been measured through the use of the RoC tool. The main recommendation is that there be a clear understanding of competitiveness and what its benefits to the South African construction industry are whilst at the same time the RoC is acknowledged as the tool embedded with functionalities able to measure this competitiveness amongst graded contractors. The RoC would allow construction clients to not only measure contractor competitiveness but also that they may have an improved ability to measure the direct impacts of contractor development interventions. / Lolucubungulo lugxile ekubhekeni izimo ezinqala ngaphakathi komkhakha wezokwakha.

The construction industry in South Africa is envisaged to play a pivotal role in the reconstruction of the South African economy, via the delivery of economic and social infrastructure. The skewed ownership I patterns prevalent in the construction sector, resulted in the South African government utilising public sector procurement as a mechanism to address these imbalances, and to promote wider participation I in public sector construction opportunities. This dissertation analyses the role of the construction industry in South Africa, and explores the rationale behind utilising public sector procurement as a mechanism to promote wider participation in the construction industry in South Africa. The research then focuses on the application of the Affirmative Procurement Policy (APP) on construction projects procured by the National Department of Public Works, in order to evaluate the impact which this policy has had on the growth and development of Affirmable Business Enterprises (ABEs). The research evaluates the primary policy outcomes, via the development of appropriate indices and a diagnostic quadrant comparator, and concludes that the application of the APP has had a positive impact on ABE participation, with levels of participation varying across construction sub sectors and categories. It was also found that financial premiums, borne by the State in adopting this policy, were nominal when compared with the initial projected outcomes and the overall benefits. The overall performance of ABEs, measured against that of non-ABEs, was then tested to ascertain whether the adoption of the APP was a necessary and sufficient condition for ABE enablement and empowerment. The research concludes that there is a difference in overall performance between J ABEs and non-ABEs, and that supply side interventions and capacitation programmes are required to mitigate the increased risk exposure by the State, when engaging ABEs on construction projects. The : research also analyses the variation in the levels of participation of ABEs, in the different construction sub sectors and concludes that the manner in which ABEs are structured and their internal business processes tend to establish operational limitations, which influence their scope of activitiies to a larger extent than the existence of eternal sub sector thresholds. Similar characteristics were,observed in non-ABEs of a similar size, inferring that the problems encountered relate to business development and growth of small and medium enterprises, in general. The research also. analyses the impact that the APP has had on subcontracting relationships and the promotion of structured joint ventures. It concludes that whilst the requirements of the APP has seen the development of formalised subcontracting relationships, the form of subcontracts that are currently utilised do not comply with the requirements outlined in the APP, which are aimed at eradicating unfair subcontracting conditions. The adoption of the APP has seen an increase in structured joint ventures between ABEs and larger established contractors. The analysis of these joint ventures concludes that they provide an effective means of transferring expertise, provided that they are structured appropriately. The dissertation concludes with recommendations on APP policy refinements, mechanisms to enhance compliance and opportunities for international application. The recent enactment of the Preferential Procurement Policy Act (Act 5 of 20(0) in South Africa indicates that several elements of the APP are likely to be prescribed as mandatory requirements for public sector procurement by different government institutions and across the different industrial sectors. It is therefore important that the areas identified for further research be pursued, to ensure optimal policy outcomes across a range of industrial sectors. / Thesis (Ph.D.)-University of Natal, Durban, 2000.

A DISSERTATION PRESENTED TO THE HIGHER DEGREES COMMITTEE OF THE CAPE PENINSULA UNIVERSITY OF TECHNOLOGY IN FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTERS OF TECHNOLOGY: CONSTRUCTION MANAGEMENT CAPE PENINSULA UNIVERSITY OF TECHNOLOGY, 2008 / This study investigated the impact of variation orders on project performance in order to take proactive measure to reduce them. The study had the following objectives, namely (1) to investigate the prevalence of variation orders on construction projects; (2) to determine the cost impact of variation orders; (3) to examine to what extent variation orders added value to construction projects; (4) to determine whether the activities associated with variation orders may be regarded as waste; (5) to identify the predominant origin agent as well as the causes of variation orders; and (6) to establish the nature and extent of the impact of variation orders on overall project performance. Literature relative to the research area was extensively reviewed. The data gathering approaches included an exploratory study on costs of variation orders on two construction projects, interviews with three top management personnel in construction contracting companies, the audit of site instructions with regard to waste and their value-addedness and self-administered questionnaires. A purposive sampling method was followed to identify participants into the study. The audit of site instructions revealed that most variation orders were beneficial. However, 14% of site instructions had waste associated with them. It was possible to quantify apparent waste associated with variation orders by means of an ‘origin-cause matrix’ designed for that purpose. Problematic situations arising from the occurrence of variation orders included discrepancies between the claimed and certified amounts. Variation orders impacted project performance with regard to cost and time overruns and disputes between parties to the contract. Most variation orders involved additional works. The complexity of works was the most predominant factor influencing the occurrence of variation orders. The reduction of the occurrence of variation orders was traced back to the pre-contract stage given that the most predominant origin agent of variation orders was the client and then due to an unclear brief of works to be executed. Suggestions regarding the reduction of variation orders include (1) adequate planning in advance is required by all involved parties before works start on site, (2) consultants should do a thorough concluding design and working drawings and contract documents should be complete at tender stage, (3) clients should provide clear brief, (4) enhance communication and all parties should be proactive at all times, (5) works should be supervised with an experienced and dedicated supervisor and (6) consultant should ensure that the design/specifications fall within the approved budget and the budget team should be appointed and participate during the design phase. The study suggests further investigation regarding the development of a more equitable basis of valuation of cost recovery which was beyond the scope of this research.

M.Ing.(Engineering Management) / Delays are a major problem faced by construction companies. The majority of the leading delays factors found from reviewing other studies were avoidable delay factors. The avoidable delay factors are factors caused only by the contractor. The reviewed studies gave recommendations for addressing the delay factors; however this study found that projects nevertheless still failing in South African construction industry and other countries even after the various studies made recommendations on how to avoid the delay factors. The objectives of this study were to establish the top ten avoidable delay factors and their mitigation measures in various countries and also to establish which of the proposed mitigation measures for each of the top ten avoidable delay factors were believed to be the answer in South African construction industry. A questionnaire was developed with questions that will probe the respondents to select the mitigation measures that will address each of the ten avoidable delay factors. The option answers were specifically designed to be close-ended. The size of the sample required was 80 and this study managed to get 82 responses. The survey was launched using SurveyMonkey which is an online survey platform. The data received was analysed for reliability and validity. The reliability was determined using Pearson Correlation Coefficient and was applied using the testretest approach. All questions had a coefficient greater than 0.6 which meant that the responses were reliable (strong). The validity was established using face validity. The responses were analysed to establish which mitigation measures have more frequency of selection. Some of the questions had some mitigation measures receiving more than 80% of the selection and some questions had some mitigation measures getting almost the same percentage selection. Most (60%) of the provinces of South Africa agreed on which mitigation measure must be used for addressing the avoidable delay factors.

Thesis (MBA)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Expenditure on South African public sector projects is vital to infrastructure development and creating employment opportunities in the country. The submission of tenders by contractors is the traditional procurement method utilised in awarding contracts. The traditional tender procurement method is not only costly, but the lowest-bid method does not ensure that the eventual project at completion is the most cost effective. Although regulatory frameworks are in place to ensure that public sector projects are awarded to suitable contractors, there are numerous examples of public sector projects that have been awarded to incompetent contractors. The traditional tender procurement method is non-collaborative in its composition, as the contractors executing the work are not part of the design team. Furthermore, industry stakeholders’ perceptions influence procurement method preferences. This research project investigates whether the tender procurement method is best suited to meet the South African public sector’s requirements and achieve infrastructural development so desperately required, or whether it needs to be replaced in its entirety or adapted.

M.Tech. (Construction Management) / Sophiatown residence is one of the newly built residential accommodations in University of Johannesburg. The residence is currently the biggest residence in University of Johannesburg in terms of rooms and is a residential accommodation for only students of University of Johannesburg. The residence is a three storey building and has 416 room all single rooms and 416 students occupying it. This research work is post occupancy evaluation of an education building in Johannesburg. The study evaluates the building performance; the extent to which the students are satisfied with the indoor environmental quality and investigates the extent to which the University of Johannesburg newly constructed residence is satisfactory to its occupants (students). It also evaluates the indoor environmental quality elements that affect the student’s health and common illness that affect the student’s performance. The methodology used for this study was quantitative. A structured questionnaire with multiple choices, scaled, matrix-type and open ended question was used to conduct the interview and obtain data during the survey. Findings from the survey revealed that the building is not performing as intended because the occupants needed improvements in some area in the residence like; quality of natural light in there room, size of the study hall, quality of space provided in there study hall and others. The students were satisfied with the building although they need improvements in the study hall, toilet and bathroom, kitchen and TV room, internet services and others. However, students need little improvement in the quality of artificial light in their room, quality of natural light in their room, size of their study hall, and others. They also needed improvements in the size of their room, temperature in their room, noise level in the study hall (ability to have conversation without neighbors overhearing it), and others. Lastly, it was revealed that Fatigue (tiredness) is the most commonly experience illness while nausea is most frequently illness had and also affect the students’ performance. Based on the findings from the study, it is recommended that the institution evaluates the IEQ at specific intervals to ensure that occupants are happy at all times and also to empower the executive managers in such a way that they are able to choose the correct materials during the design stage to promote good indoor air quality. It is important that the managers attend workshops (trainings) so that they have a better understanding of good indoor air quality that will keep occupants satisfied with the performance of the building.

M.Tech. (Construction Management) / Focusing on the dilapidated state of public schools infrastructure in the Gauteng Province of South Africa, this study presents findings on the current state of public schools infrastructure, why public schools infrastructure is in a dilapidated state, various factors which contribute to the dilapidated state of public schools infrastructure, an overview of measures which have been undertaken to improve the state of public schools infrastructure and subsequently proposes a multi stakeholder framework for the maintenance of public schools infrastructure. To achieve the objectives of the study, a detailed literature review of Botswana, Nigeria, United States of America and South Africa were compiled on public schools infrastructure. A set of multiple questionnaires were designed to collect data from 34 public schools in Gauteng Province of South Africa. The field survey comprised of Department of Education Officials, maintenance contractors, school governing body members, school Teachers, school principals and community members. There are multiple factors which when they occur lead to the dilapidation of public schools infrastructure. The primary factors include that maintenance works are undertaken in a disjointed manner with no clear strategy, inadequate government intervention, no sense of ownership for the schools by learners, teachers, parents and community members, inadequate funds allocated to schools, vandalism, lack of maintenance, funds not allocated based on individual school needs, neglect, deferred maintenance and overcrowding. The study is restricted to the Gauteng Province of South Africa. The selection of Gauteng as a case study has been mainly influenced by accessibility to the researcher and its high rate of overcrowding in schools which is also accompanied by high public schools infrastructure backlog. The findings of the research will be taken as representative for the entire country.The study provides a detailed comprehension on the various factors which contribute to the dilapidated state of public schools infrastructure and further proposes a multi stakeholder framework for the proper maintenance of public schools infrastructure.The study provides an understanding of the various factors so as to enhance maintenance of existing public schools infrastructure and the capability of the government to build new schools or extend the existing schools to meet the demand.
