Impact of Design Cost on Design Bid Build Project Performance
Some study show that the performance of DBB projects depend upon the quality of the design. If errors are minimized during the design phase, then, construction costs are reduced and schedule growth are minimized. Therefore it is necessary that owners focus more on the project's design phase in order to improve the construction project performance. Based on prior research, this study hypothesizes that there are relationships between design costs and construction project performance of DBB public projects. Data was collected and analyzed regarding design cost, construction award cost, final construction cost, and construction duration of a set of DBB public projects. The analysis showed that the design cost was significantly correlated with construction cost growth and schedule growth of the public projects under evaluation. In addition, the design cost was found to have a significant correlation with the final construction cost. Using, a regression model developed to predict the final construction cost of a road project, and also using the design cost as an input variable, the R-square value of this model was found to be 58.7%. This result indicates that when design costs are higher, project construction performance is better.
