- Description: Lack of quality in the South African construction industry is causing various problems for different stakeholders. The causes of this lack in quality are due to various different attributes. Corruption has become one of the leading causes with regards to lack of quality. Quality assurance can mitigate or eliminate defects through the implementation of a quality management system. Defects manifest primarily through cracking, dampness, detachment, and water leaks. Defects are categorized as structural, subsidence, acoustic and thermal. In terms of time, defects are either patent or latent, and can be discovered through observation, inspection and various tests. The causes of defects are ultimately due to error or omission, either during design or during the construction phases. Defects may also result due to procurement related factors, such as appointment of incompetent contractors. The result of defects is customer dissatisfaction, rework and disputes. Non-conformance to requirements results in rework and this in turn contributes to time and cost overruns. The aim of this research was to investigate the greatest cause that leads to defects in houses; the most common type of defect; and why projects fail in term of project management terms (due to defects). Results of quantitative research amongst professionals within the construction industry in the Western and Eastern Cape of South Africa as well as literature that has been reviewed form the basis of this study. Architectural practices, consulting engineering practices, and general building contractors were selected on a random sample basis, and surveyed using an online questionnaire. The study revealed that inadequate artisan skills is the biggest cause leading to defects in houses, and that cracks are the most frequent type of defect occurring. Projects fail in project management terms because of defects as the construction time of the projects are increased. The study revealed that construction related causes of defects dominate over design related causes. This study should be of value to both construction industry professionals as well as their clients.

- Description: The legitimate existence of the Project Management Profession in the South African construction industry needs to relate to positive project influence on the industry roleplayers. This study assessed the perceived lack of recognition and acceptance of Project Management as a stand-alone profession relating to: · Appointments of Project Managers being questioned due to a perceived lack of influence and impact on project success. · Project Managers not being recognised as an integral part of the industry. · Project Management not being perceived as having a unique and defined function. Interviews were held with 23 industry role-players made up of clients, contractors and consultants. The interviews solicited input on the role-players’ perception and experience related to the influence of Project Management over the past 10 years, not only on a list of success criteria relative to their own role in the industry, but also their perception of the influence on the other defined role-player groups. Included in the interview questionnaire was also a range of general questions to refine the feedback and further test the hypotheses. The data were interpreted and analysed by comparing the feedback of the respondents as a combination and separately as groups. The results of the study indicate that: · Project Management could be seen as a legitimate part of the industry; · The industry role-players perceive Project Management as making an impact and having a growing influence on the industry; A specific but broad set of skills are required by Project Managers; · The Project Management function cannot be fulfilled by other consultants, but there are project related criteria which should be considered before making a final judgment. These criteria relate to project size and complexity; and · Project Management is currently perceived to be more related to a specific person’s skill than to a specific profession. The study’s aim was to influence and inform the views of industry role-players on the appointment of a Project Manager in the construction industry.
