M.Tech. (Construction Management) / The construction industry is a key sector in the development and economic growth of South Africa. However, the industry has not escaped the challenges facing other countries worldwide in terms of delivering construction projects within budget and on time as stipulated in the contracts. This study assesses the causes, effects and measures of minimising construction projects cost and schedule overruns in the Gauteng Province of South Africa. The data used in this study were derived from both primary and secondary sources. The secondary data was collected via detailed review of related literature. The primary data was collected through a questionnaire which was distributed to construction professionals. Out of the 200 questionnaires sent out, 146 were received representing a 73% response rate. Findings revealed that inadequate planning, change in project design, poor project management, inadequate financial provision and inaccurate estimates were the major causes of construction projects cost overruns. Furthermore the study also showed that the causes of construction projects schedule overruns in Gauteng province included: slowness in decision making process, reworks due to errors during construction, delays in approving major changes in the scope of work, delay in material delivery, shortage of skilled equipment operators and low productivity level of workers. Additionally, it was observed that construction project delays, increased project cost due to extension of time, liability of companies to bad debt and project abandonment. The study also revealed that extension of time, cost overruns, loss of profit, disputes and poor quality of work due to hurrying the project were the major effects of construction projects schedule overruns. Likewise, the study revealed that adequate planning, proper pre-contract planning, proper project implementation and management and good workmanship were the most effective ways of minimising construction projects cost overruns. Finally the results revealed that proper project planning and scheduling, effective strategic planning, site management and supervision, frequent coordination between the construction team, availability of clear information and communication channels were the most effective ways of minimising construction projects schedule overruns in the Gauteng Province of South Africa. It is recommended that all members of construction teams be trained and educated of the factors that cause project cost and schedule overruns in order to minimise these overruns.
