The issue of cost overruns in construction has indeed marred the quest for monetary worth in contracts executed as the country gears up to fill infrastructural gap as part of efforts towards national development. The existence of cost overruns has also affected the significant contributions aimed at the improvement to the overall Gross Domestic Product (GDP). Cost overruns inevitably yield overruns in construction of projects, the effects of which results in slippage of project schedules, a situation which does not augurs well for the construction industry. This, undoubtedly, creates implication of the variations in the budgets earmarked for the construction. In view of this, the study assessed the implications of cost overruns in the construction industry in Ghana. As a research design based on qualitative and quantitative approaches, the study relied on purposive sampling technique, a sample size of 117 respondents was selected for data collection. A 100% response rate was achieved in the questionnaire administration. There should also be explicit legal regime so as to legislate for the contractors and consultants to ensure that the best practices and standards tenets of construction cost estimates are carried out within the legal framework so as to manage cost overruns in construction. The key findings of study included inadequate skilled in estimating total project cost and disrespect for expert advice by contractors. It was also discovered that, problem of non-compliance with laid down rules concerning bidding for contracts, lack of appropriate bidding process and inadequate measures for evaluating the projects under construction are contributing factor. Among the key recommendations of the study was that there should be effective evaluation of project-cost relationship by the appropriate agencies tasked with the above stated responsibility. Regular time-cost trade-off analysis should be undertaken at all levels of the progress of the contract to be diligently carried out so as to shorten the project duration and to further get rid of any possible emergence of cost overruns in construction.
