dc.description.abstractBuilding construction projects in Ghana’s construction industry are facing many quality issues most especially with design and contract documentation. The main purpose of this study was to assess the quality of design and contract documentation, and the impact it has on the performance of construction projects in Northern Ghana. A questionnaire survey was performed on 85 respondents (40 Consultants, 25 Clients, and 20 Contractors), 52 responses were received representing 61.2% response rate, and 96.15% of these respondents acknowledged there were indeed deficiencies in design and contract documentation. The data were analyzed using Relative Importance Index (RII) and Kendall’s concordance testing. Majority believed that consultants were mostly responsible for this problem followed by clients. A conclusion was drawn based on the data analysis that, out of the 40 factors, these were the critical factors that bring about design and documentation deficiencies. They are: the selection of designers on the basis of lowest price selection strategy (Lowest bid approach), the unwillingness to pay fees commensurate with the design of high-quality services, the last minute changes by the client, insufficient design reviews with relevant parties, the slow payments system for design services, and the insufficient and missing input information from the client. It was also concluded that the following affected the time and cost performance of public construction projects in Northern Ghana which are in order of the degree of severity: Projects abandonment, Delays (Time overrun), Cost overrun, Payment claims, and Variation/Change orders. Recommended to the Clients and Consultants to help in the prevention of design and contract documentation deficiencies in construction projects in Northern Ghana are the following strategies. These are: Clients must ensure that consultancy fees are proportionate to the required service quality, Consultants should make sure there is an adequate review of design and documentation with all stakeholders involved, and Clients must ensure that the selection of consultants is on meritorious grounds. And the rest are Prompt changes should be tolerated if the need be, Ensuring timely and regular payments for design service providers and that Clients must make sure that briefs are adequate, clear, precise and conciseen_US
