Reducing CRR in fast-track projects through BIM

Rework is one of the most commonly encountered issues that face construction projects, leading to potential loss of money and delays. The aim of this study is to investigate the potential role of Building Information Modelling (BIM) in reducing Client-Related Rework (CRR) when set within the context of fast-track construction projects in Egypt. In order to study this issue survey data was collected from 51 construction professionals within the Egyptian private construction sector with experience in fast-track projects through a self-administered questionnaire composed of fourteen closed and open-ended subgroup of questions, whose aim is to gain an understanding of the main sources of CRR in the industry. The survey results revealed that the majority of the respondents (92.1%) had experienced CRR in construction projects, resulting in an average project cost increase of 22% and an average delay of 23%, as well as formulating the basis for a novel Severity Index (SI), which was devised in order to rank CRR causes, with its finding revealing "Clients' financial problems", "Impediment in prompting the decision making of the client" and "Replacement of materials by the client", as the biggest contributors to CRR. The survey also highlights visualization as a potential solution to CRR, with eight case studies from literature as well as one from the Egyptian market being used to validate the use of BIM in the reduction of CRR. Findings illustrated that the use of BIM in the Egypt is similar to findings in literature, with BIM resulting in rework cost and schedule reduction of 49 and 57 percent respectively.
