RISK ANALYSIS OF QUALITY DEVIATION IN THE IMPLEMENTATION OF FLEXIBLE PAVEMENT ROAD PROJECTS

Abstract

The road is the primary support in the development of the country. The quality of the road must be good so that the passing vehicles are safe and comfortable. However, in reality, there are many road works whose quality is not following the requirement. The quality mismatches, which are often found during the process of carrying out road works, and maintenance, cause the damage, ahead of the planned road life, and the rework, which contribute negatively to the project costs and profit. As for the size of the cost due to rework, it depends on the type and the volume of works. The additional costs are not only in the form of direct costs but also in indirect costs, which can be even higher. The impact of indirect costs can be in the form of overhead costs, administrative costs, motivation, and morale of the workers, and others. The purpose of the study is to identify the risks that affect the quality and the performance of the project implementation, to determine the impact of the causes of the risk on the quality and the performance of the project implementation, to manage risk by reducing the likelihood of risk occurring, and to reduce the impact if the same problems occurs sometime in the future. The research was conducted on national road projects with flexible pavement types in Indonesia.
