Besides, contractors are subject to take more risks caused by the long project period. Since the fair and reasonable price-adjusting mechanism is not established, the disputes and claims for compensation happened frequently. Under the pressure of contractors’ pleading and protests, authorities are forced to amend the legulations repeatedly, which violates the consistency of government administration. Due to the wide varieties of construction types, it is improper to apply general price index to adjust contract price for all kinds of construction when encountering big price fluctuation, and the risks between public sectors and contractors can not be effectively reduced either. Nevertheless, using the individual item as the basis of calculating formula for price-adjusting is complex and isn’t accepted by authorities. It is unfavorable in establishing price-adjusting mechanism to consider the differences of construction types. Furthermore, the underestimation of price adjustment by index leads to bidding failure or lag behind schedule, even leads to contractors’ bankruptcy, which results in delay of progress in contruction project and is forced to modify construction plan. For the above reasons, this research takes international rules for reference. By discussing current problem in price adjustment by index, comparing the differences between general contract example and FIDIC formula, and employing CCI provided by DGBAS, a localized formula is constructed. Also, based on the case studies of Bridges construction project, this research proposes an easier price-adjusting formula which meets the acceptable precision in order to develop a fair and reasonable price-adjusting mechanism for authority.
