Abstract

This study aims at investigating the relationship between (1) contract price and tendering procedure (2) contract price and threshold value (3) contract price and contract type (4) contract price/approximate cost ratio and tendering procedure. Within this context, a total of 219.546 tender procedures of construction work data between the years 2007 and 2017, which involves open tender procedures worth approximately 169.9 million USD, restricted tender procedures worth 25.9 million USD, negotiated tender procedures worth approximately 25.6 USD, were analyzed The results show that tendering procedure, threshold value and the contract type have a statistically significant effect on the contract prices. In addition, negotiated tender procedure causes a statistical significance on the contract price/approximate cost ratio.
