Risk Factors Contributing to Time Delay and Cost Overruns in Bridge Construction Projects on Prithvi Highway in Nepal

Abstract

This study purpose to identify the fundamental factors that causes delay in bridge construction project at Mugling to Dharke section (68 KM) of Prithive Highway in Nepal, which results risk factor contributing to delay and cost overrun allocated for this type of engineering project and cause major issues for both the client and the contractor. The difference between the cost at completion and that originally estimated, known as cost overrun. The construction of bridge is often beset by challenges like time delays and cost overruns, resulting in addition of project cost and decreased public satisfaction. This study’s research methodology involves a literature review and a questionnaire survey. Thoroughly literature review, thirty-nine common risk factor causes of delay were identified. Questionnaire survey is accomplished among construction professionals and technical expert of bridge project. Drawing upon existing literature and case studies, the abstract highlights key factors contributing to delays and overruns, including design changes, unforeseen site conditions, regulatory problems, and inadequate project management practices.
