Abstract
One of the vital success elements of a construction project is the accuracy of the estimation of construction cost. This study is aimed at developing a cost profile for road projects in Ghana. Pro forma was designed to retrieve historical cost data of completed road projects in Ghana. The pro forma retrieved data such as the initial budgeted cost and final construction cost of road projects, location of road projects, features of road projects, the scope of road projects (new project, renovation work, upgrade work or replacement work), type of road projects, and classification of road projects. Cost data were analyzed using descriptive analysis and probability distributions such as cumulative density functions and probability density functions. From the findings, estimates prepared for road projects in Ghana can be expected to be below the final construction cost by approximately 20% as most of the completed road projects in Ghana experience cost overrun.
