Cost estimating is an assessment of the anticipated cost of a construction project. The exactness of such estimate has a serious effect on the anticipated income of the contractor. Hence, a certain contingency premium should be added to the base estimate to increase the level of confidence. These factors differ from country to country due to environmental, geographical, and technological constraints. The primary objectives of the study are to identify the significant factors affecting the construction costs and to determine the impact of the factors affecting the exactness of the estimates in Afghanistan as a case study. Through this study, the main factors to affect the accuracy of the cost estimates were clearly marked in the typical developing countries certainly in Afghanistan. Because as a developing country Afghanistan is facing challenges that are not in the developed world and these challenges cause costs for the infrastructure. These specific cost factors are: Security condition, Project geographical location, Availability of Labor, Political interruption, Material related problems, Quality of construction materials, Size of the project, Availability of modern equipment required, Social and cultural issues. This study shows that there are several factors affecting the project cost estimating significantly.
