The Effects of Design Information on Reliability of Progress and Cost Estimates of Construction Projects: The Case of Two Civil Engineering Projects
Continuing national disquiet concerning the late completion of road construction projects, high-cost overruns and premature failures of roads partly attributed to inadequate design information is quite worrying. The paper investigated the effects of design information on reliability of progress and cost estimates on two road construction projects in the Brong Ahafo and the Upper East Regions of Ghana. A case study was conducted on the two projects which involved the content analysis of the design documents, interviews with the industry players and personal observations. The study revealed among other things such as lack of design plans before tendering, disparities between design drawing information and Bill of Quantity (BoQ) information, inadequate site investigation and delays in taking decision on variations, affected the smooth progress of these projects. It is recommended that all the stakeholders in the road construction industry treat road design and its related matters with the maximum attention it deserves to curtail the huge avoidable cost the nation is incurring.
