Impact of Performance Based Contract Implementation on National Road Maintenance Project to Road Functional Performance

摘要

The national road network has a significant role in promoting the national economy in Indonesia. But the national road network conditions in general are still not satisfactory although the government continues to improve the technical standards of road maintenance which contributes to the high unit cost of road maintenance. To overcome this classical problem, now the road agencies began to implement alternative road maintenance contracts known as Performance Based Contract (PBC). Successful practice of PBC implementation in various countries indicates that the PBC is able to produce a good road service performance compared with the implementation of in-house system or contract-based input on road maintenance projects. This study aims to measure the impact of PBC implementation on the national road maintenance project in Indonesia with the type of flexible pavement. The impact of PBC is focused on the functional performance, which is measured using a model of IIRMS and expressed in the International Roughness Index (IRI) value. The case study conducted on one of the PBC pilot projects that are in the segment of northern coast of West Java. The results showed that the implementation of PBC for national road maintenance projects proven to ensure the quality and road service performance for the long term.
