A DOSE to compare the level of performance between construction projects

The aim of this paper was to compare the level of performance (success) of construction projects between selected countries based on the concept of iron triangle. Following this, the major construction delays, cost overruns and quality factors were identified through an in-depth review of previous research works conducted in Denmark, Nigeria and Gaza Strip. The aggregate impacts of these factors were computed and compared between these countries. The results show that in the case of Denmark, the aggregate impact of the factors responsible for delay, cost overrun and poor quality was found in the impact interval between [0.60–0.80], but in the case of Gaza Strip and Nigeria, the aggregate impacts were found in the impact interval between [0.80–1.0]. This shows that construction projects in Denmark are found to be performed better relative to Nigeria and Gaza Strip.
