摘要：Time and cost overruns in construction projects are well known around the world. There are several fundamental root causes of such overruns. This paper addresses the engineering related causes which lead the project to miss its targets. Four main Factors were identified in the literatures; discrepancies, design errors, rework and variation order. It has been found that these factors are correlated to each other, and surely impacting the schedule and budget performance. Main engineering causes are somewhat similar between countries in the globe, and major change of design is very common. The study generates a conceptual framework of engineering related causes, to be investigated further in the future.
