Rework in Construction Projects and Impact of BIM on Rework Causes

Most projects suffer from construction overruns. Hence, making them strive to improve project performance. Several studies have assessed causes that might lead to overruns in construction; rework has been considered a prime cause of overruns in the construction industry. Thus, one of the goals of this study is identifying causes of the rework in construction projects, having been conducted by a systematic literature review that has identified 31 causes of rework. The 31 causes were identified, refined into 24, and categorized into 5 groups. This study must specify a particular country as a case to study. The Saudi Arabian Construction industry is highly active., this study shall measure the existence and impact of rework on construction projects while being supported by a questionnaire according to the Likert scale ranking. Total of 74 participants returned the questionnaire, after which Cronbach's Alpha reliability test was conducted to ensure validity. Furthermore, the total importance index methodology was adopted to determine the rank of each cause, the ranks of the rework reasons in this study were compared to earlier studies in other nations to demonstrate a variation in prioritization of the rework causes. Finally, this study measured the manageability of rework causes through BIM. A comparative study between those who utilized BIM as an auxiliary tool with those who did not were conducted to evaluate whether BIM adoption decreases the occurrence of rework. The F.I was adopted to rank the rework causes in this comparative study. Based on this study's results, stakeholders in the construction sector should consider the critical causes of rework and plan accordingly in the preliminary stages of the project. Additionally, based on the comparative study of the impact of BIM utilization, Stakeholders in the construction field can decide whether BIM will be practical in mitigating the occurrence of rework.
