Pandemic Construction Delay and Cost Overrun Analysis in Water Resource Project

Abstract

Shimelis Getaneh and ML Kansal

This research aims to identify the most critical factors that influence cost and time overruns in water resource projects and assess the risk associated with cost and time overruns. There were fifty (50) time delay factors and fifty-five (55) cost overrun factors included in this study. Identifying the Cause for the project's delay was greatly aided by studying the literature and discussions with various parties. This questionnaire aimed to assess the severity, frequency of occurrence, and significance of the defined courses. The factor was compared and ranked based on the analyses of the Relative Importance Index (RII). Cost overrun-related factors were categorized into six groups i.e. client, contractor, consultant, labour, external, and equipment whereas, time overrun administration, financial, contractor, consultant, and material-related factors. This factor was compared and ranked based on the analyses of the Relative Importance Index (RII). Based on the studies, contractor and external-related factors significantly impacted the frequency and severity of cost overrun compared to other sub-groups. Similarly, we compared the major contributor factor in the project's running time; based on the analysis of the material-related and financial-related problems; there was a significant impact in increasing the project's frequency and severity, respectively. Furthermore, in this research, the percentage of risk of cost and time overrun was also studied in detail. Based on that, external related factors had a high risk for cost overrun compared to the other five categories, and administration-related factors were also exposed time overruns to be raised.
