Abstract
Construction schedule overruns are not uncommon on construction projects world over and the South African construction
industry has not escaped the challenges of failing to deliver projects on time. In order to find mitigation measures of schedule
overruns, the first step is to identify the causes of these overruns. This paper assesses the effects of construction projects schedule
overruns in the Gauteng – South African construction industry. The data used in this paper were derived from both primary and
secondary sources. The secondary data was collected via a detailed review of related literature. The primary data was collected
through a well-structured questionnaire which was distributed to construction professionals, who include: Architects, quantity
surveyors, civil engineers, construction mangers and project managers. Out of the 200 questionnaires sent out, 146 were received
back representing a 73% response rate. Data received from the questionnaires was analysed using descriptive statistics
procedures. Findings from the study revealed that extension of time, cost overruns, loss of profit, disputes, poor quality of work
due to hurrying the project, creates stress to the client, acceleration losses, bad reputation with contraction team, claims and delay
in getting profit by the client were the major effects of construction projects schedule overruns in Gauteng, South Africa. The
study contributes to the body of knowledge on the subject of the effects of construction project schedule overruns in Gauteng,
