Analysis of factors affecting the accuracy of early cost estimate in construction projects

Quality early cost estimate can be measured from its level of accuracy. Early cost estimates prepared at the early stage of project inceptions, therefore early cost estimates have an important function as a starting point and a benchmark for project planning and controling in the future project stag...
