- Description: Abstract: The significant impact of construction projects on a nation has been characterized in literature in terms of infrastructure development and job creation. These projects are nevertheless associated with various risks that need to be managed to ensure successful delivery. Hence, the identification of these risk factors is of utmost importance. Therefore, this study aimed at assessing contractors‘ perception of critical risk factors in construction projects in Gauteng (South Africa). Explorative and questionnaire survey methods were employed to obtain data from literature and construction professionals all practising in Gauteng. Results revealed that supply of faulty materials, poor communication between involved parties, financial failure of the contractor, working at dangerous areas and closure were the five critical risk factors in construction projects. It is obvious from the results that the knowledge of the identified critical risk factors furnishes invaluable information to the construction contractor concerning what risk variables to focus attention on in construction activities. The paper contributes to the identification of critical risk factors in construction projects from an objective point.

- Description: Abstract: Organisations are established to address a particular issue of the society and their success or failure in achieving their set goals and objectives largely depend on both external and internal factors. Inthis study, sources of failure of small and medium businesses in the construction industry were examined and remedies that can be implemented to reduce the failures were evaluated. Data for the study were collected through administration of structured questionnaire on owners of small and medium construction companies. Itwas revealed that the major causes of small business failure are lack of financial managerial ability and general administration of the business. Challenges faced by these firms include inadequate managerial skills and planning, lack of access to work opportunities, prolonged economic recession, lack of financial skills, competition, incompetent employees and lack of basic business, technical and pricing skills. Small construction businesses need to be supported by government and other stakeholders in order for them to be sustainable and this will also guarantee job security for construction professionals and other form of workforce employed in the companies. The managers and directors of these firms should attend and participate in conferences, workshops, seminars and other forms of leadership meetings within and outside the country to improve their leadership, business and organisation skills.

Impact significance of construction clients on designers’ and contractors’ health and safety culture- An exploratory Delphi study. Proceedings of the CIB W99 International conference on Construction health and safety, Washington DC, USA, 24-26 August 2011
- Description: Designers and Contractors’ top management have been identified in many studies to be of great importance to health and safety performance and its continual improvement. Therefore developing strategies that support and motivate designers and contractor top management to implement health and safety elements would ensure a gradual and sustained improvement of health and safety in the construction industry. In order to determine the impact significance of clients/owners on designers and contractor top management, a Delphi study was conducted. Findings from the study where that client culture has critical impact significance on designers and contractors’ top management culture. Further findings were that implementation of health and safety elements by designers and contractors were ‘very likely to occur’ with clients influence. This paper reports on findings from an analysis of impact significance of clients on designers and contractors. It will underscore the point that has been made before using different methodologies that client health and safety culture is critical to designers and contractors’ health and safety culture. The paper argues that an improved client health and safety culture will result in an improved health safety culture of designers and contractors. Pursuing this strategy can result in prevention of many accidents and incidents

- Description: Abstract: The Construction Industry is by nature one of the most diverse working environments. The South African Construction Industry is not an exception to this rule. The Industry has witnessed great diversity in its workforce mix at all levels since the return to democracy in 1994. Thus, peoples from erstwhile segregated communities are brought together to work in achieving a common project objective. The intricate influence of this cultural mix and the pressure it exerts paper provides insight into the influence of culture and cultural difference on teams working together towards project delivery. The study adopts a mixed method approach by use of interviews and questionnaires through a convenience sampling of construction professionals in the Gauteng Province, South Africa. Findings from this research confirm that factors such as sociability, masculinity, power, equity, individualism, avoidance, collectivism are cultural dimensions prominent in multicultural teams. The influences of cultural aspects that rank highest are irritation due to misunderstanding, encouraging team building, motivating workers to work harder. The study concludes that while a lot has been done in integrating project teams from different cultures in the South African construction industry efforts should be concentrated on mitigating the effect of masculinity and irritation due to misunderstanding. It is recommended that Project Managers and Construction managers should more sensitive to the influence of cultural dimensions and deploy cultural awareness and appropriate leadership styles in mitigating its effects while channeling the positive influences towards organizational benefits. This research has provided insight into intrinsic cultural dimensions among construction industry workers in the Gauteng Province of South Africa and provides useful policy input for the Construction Industry Development Board and industry practitioners at large. The research is limited to the experiences of Construction Industry professionals in the Gauteng Province of South Africa due to the constraint of time.

- Description: Abstract: The delivery of construction project is often affected by several risks factors which can threaten the achievement of project outcome in terms of time, cost, quality and health and safety (H&S). Regrettably, there is a paucity of empirical studies investigating the impact of these risks on project outcome in the South African construction industry (SACI), especially in the small and medium enterprises (SMEs) sector. Hence, the current study sought to investigate the impact of these risk factors on project outcome of SMEs in the Gauteng province of South Africa. A structured questionnaire consisting of nineteen risk factors was used to collect data from SMEs who were conveniently sampled. The data was analysed using the Statistical Package for the Social Sciences (SPSS) version 23, computing descriptive statistics. Empirical findings revealed that time and cost were both impacted by variation by the client, design variation, incomplete approval and unsuitable construction program planning while incomplete or inaccurate cost estimates impacted highly on cost and quality objectives. Furthermore, accidents due to poor safety procedure, the absence of fire safety systems on site, equipment damage and labour injuries were deemed to have a high impact on project H&S outcome. The results of the study will boost the knowledge of industry practitioners on the risk factors affecting project outcome of SMEs.

- Description: Abstract: Quality principles and supplier selection play an important role in projects especially where the customer is planning to outsource the work to an external organisation. The application of quality principles will help ensure that work that is going to be carried out is planned well in advance and the necessary measures are put in place to ensure that it is carried out as required. Supplier selection is a process where potential suppliers and contractors are invited to submit their information in order to be considered for work that the customer has. With the invitation, requirements will be attached and they need to show that they are capable of turning those requirements to actual output. The customer will have pre-defined criteria that will be used for evaluations and the best capable supplier or contractor will then be selected to execute the job. It has been realised that as much as quality principles are defined and the supplier selection process is adopted on projects, failure can still be experienced. This research looked at two industry cases in the construction of electricity networks. One project was for the construction of four 132kV lines and the other project focused on the relocation of lines which were in the way of some township development. The study adopted a questionnaire as a data collection tool, which was sent to the team members of both projects to complete. The results show that much as the customer was the same organisation with projects in different locations, there were slight differences in the way the projects were handled. From both projects, team members were aware of the level of quality required, requirements were put in place and the evaluation criteria used for the selection of contractors were utilised. The differences that led to project ABC failing and project XYZ being a success, were in the implementation of contract quality plans that were agreed upon before work commenced and in the performance monitoring as work was being executed. Project ABC failed due to lack of experience in enforcing what was agreed upon and not monitoring performance as stated within inspection and test plans. , M.Phil. (Engineering Management)
