ABSTRACT
The structural improvement and its extension require work zone at the stage of road
maintenance project implementation. This work zone produced a negative impact
including the decreased road capacity and travel speed. These involve road user and
social costs due to disruption of the environment nearby the project. In the U.S, road
user costs calculations were used as a delay claim in a road project completion. This
method is known as the incentive/disincentive (I/D) method. An investigation on road
user costs due to work zone in Indonesia however, has not yet been conducted. The first
stage of this study is to conduct a comparison analysis between the road users costs and
delay claims under the contract. A national road improvement project in Bali Province
on fiscal year 2012 is used as a case study. Paired statistical t-test and Wilcoxon sign
rank test were used for data paired difference test. The study results show that delay
claims are applied for one per mil (1/1000) of the contract price. Road users cost due to
work zone is an average of (13.7/1000) of the contract price. Statistical test indicated
that road user costs are not equal to delay claims stipulated in the contract (t-test
p=0.012
