dc.description.abstractConstruction project time overrun is endemic and bears both direct and indirect cost implications to project budgets. This thesis seeks to, by questionnaire measure and through empirical method assess the percentage cost escalation of TSF projects that have overran their agreed upon completion dates. Data was obtained from 56 respondents comprising of contractors (51.8%), consultants (28.6%) and clients (19.6%). Of the total respondents, 23 were project managers, 20 were Civil Engineers, 8 were Quantity Surveyors, 5 belonged to other group of professionals. The study reveals that time overrun is frequent in TSF construction projects which is indicated by 86% of respondents who indicate time overrun was experienced by their projects. 57.1% of respondents asserted that their projects overrun cost by less than 5% of the project budget due to time overrun factor. 25% of surveyed respondents indicated their projects overran cost by 5% of their project budgets, 12.5% overran 10% of their TSF project budgets whiles 3.6% overrun cost at 15% of their project budget. Generating a predictive model for time overrun from the survey data revealed capacity, project duration and project budget as independent variables and time overrun as the dependent variable. The mean variation between time overrun and capacity of TSF, project duration and project budget in relation to construction projects in Ghana are equal hence the acceptance of the null hypothesis. Twenty-one (21) factors were identified by all respondents as cost factors that emanate as a result of poorly managed time overrun causes by industry practitioners. The highest ranked cost effect was identified to be Claims (ranked 8.21) with a standard deviation of 0546. Traditional contracting is ranked the most effective procurement system for time overrun mitigation partly. The use of effective procurement systems and the possible mitigation of time overrun causes be timeously made in order to curtail the effects of cost incurred due to time overrun in TSF construction projects.en_US
