Revised unit price practice in Turkish construction works

Abstract

In Turkey, for the unit price bidding construction works based on Public Procurement Law, revised unit price is used in case of purchasing too much over the anticipated quantity in the bidding letter. In this context, the revised unit price is applied to the related work item in case of more than 20% quantity increase also with this increase should be more than 1% of the contract price. The uncertainty of how to make the revised unit price calculation is clearly defined by a formula. The basic logic in the revised unit price application is to reduce the expected benefit of the relevant work items in terms of the contractor in case of unexpected increase in the quantity of work items. In the revised unit price practices, there may be various disputes arising from the fact that contractors and/or employers cannot possess the principles of implementation. In this study, the revised unit price dispute between the employer and the contractor was discussed. Advantages/disadvantages of the applied revised unit prices in a sewage construction work; case file in the Basic Commercial Court in Kayseri, Turkey was investigated in terms of employer and contractor.
