- Description: M.Tech. (Construction Management) , Abstract: Risk management is acknowledged as a key activity in project management in order to deliver successful construction projects. However, the complexity and the risk environment in which construction projects are undertaken leads to poor project performance, especially among small and medium construction enterprises (SMEs) whose contribution to the economy is substantial. The main objective of this study was to establish the risk management practices that are tailored for the successful delivery of construction projects undertaken by SMEs. Therefore, develop a construction risk management model at project level for SMEs. A critical review of relevant literature was conducted which was used to develop a structured questionnaire survey. The questionnaire was first pilot tested with four construction SMEs before its dissemination to construction SMEs who were conveniently sampled in the Gauteng province of South Africa. A total of 225 questionnaires were sent out, 187 were returned of which 181 were deemed usable representing approximately 80% response rate. Descriptive and inferential statistics using the Statistical Package for the Social Science (SPSS) version 23 were used to empirically analyse the data. The validity and reliability of the nine factors of the risk management model were determined using Oblimin with Kaiser Normalisation rotation. Furthermore, Kaiser’s criterion and parallel analysis were also used as measures of the nine factors as well as the forty-two variables. Multiple regression analysis (MRA) was used to establish the relationships of the risk management factors and the project performance outcome. Empirical findings established that variations by the client, design variations, incomplete approval and inadequate program scheduling were deemed to have a high impact on project time outcome. It was further revealed that design variations had a high impact on project cost outcome followed by variations by the client, occurrence of dispute and incomplete or inaccurate cost estimates. Furthermore, project quality outcome was highly impacted by the lack of coordination between project participants, low management competency of subcontractors, design variations, and incomplete or inaccurate cost estimates. In addition, 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 health and safety outcome. Further exploration of the empirical findings revealed that variation by the client, design variation, incomplete approval, and unsuitable construction program planning can...

- Description: Abstract: The formation of joint ventures, between construction companies is one of the recent efforts in combating contractors’ challenges in South Africa as far as the complexity of projects is involved. However, despite the irrefutable contribution of studies undertaken in joint ventures (JV) in the construction industry in South Africa, there seems to be trivial improvement on the delivery of construction projects in joint ventures. Therefore the specific research objectives delved into, to address this gap were, challenges encountered by partners entering into joint venture construction projects, the selection criteria for joint venture partners, the benefits of participating in joint venture construction projects; the critical success factors (CSFs) that contribute to the success of joint venture construction projects and finally, identify the critical success factors which influence the performance of joint venture construction projects in South Africa. A quantitative research philosophy was adopted which is positivist philosophy to address the specific research objectives. A questionnaire was developed from an in-depth review of the existing relevant literature to collect the field data. However, to achieve the content validity of the questionnaire a pilot study was first undertaken. The final questionnaire was distributed to conveniently sampled professionals who have been involved into joint venture construction projects. The respondents were registered with the South African Council for the Project and Construction Management Professions (SACPCMP). The response rate was 28.75 %, that is; 115 responses out of a sample size of 400 respondents. The respondents were sampled from the provinces of Gauteng, Limpopo and Western Cape. The validity and reliability tests were computed using Statistical Package for Social Sciences (SPSS) version 23.0. Descriptive statistics, were quantified, including inferential statistics from the factual data obtained. The key findings established that the main challenge which the respondents experienced the most in joint venture construction projects in South Africa was: the lack of collaboration of people from different cultures. However, the commitment between partners, and complementary technical skills, were considered favorable as selection criteria of JV partners in South Africa. Moreover, the study revealed that the main benefits of entering joint ventures in South Africa were: larger projects are made feasible and possible as well as the fact that JV improves the pooling of resources i.e. human talent, financial resources, equipment. Moreover, the critical success factors that were established included: a comprehensive and fair written agreement, mutual understanding, inter... , M.Tech. (Construction Management)
