Identifying and Measuring Engineering, Procurement, and Construction (EPC) Key Performance Indicators and Management Strategies

摘要

Delay and cost overrun in construction projects are two widespread problems that arousepractitioners’ and scholars’ concern. Therefore, the objective of this study was to identify KeyPerformance Indicators (KPIs) in each of Engineering, Procurement and Construction (EPC) phasesseparately and then calculate the weight impact that is associated with each of identified KPIs.Additionally, this study aimed to find the most appropriate Best Practices (BPs) for the identifiedphase-based indicators. Through a review of existing literature, a survey was developed to collectdata from the completed construction projects. Various statistical methods, including two sampleT-test and Kruskal-Wallis test, were utilized to analyze the data. Subsequently, Epsilon-Squaredeffect size method was applied to prioritize the identified KPIs. Since the lack of communication andslowness in decision making were found as the primary schedule Performance Indicators, scheduleperformance was identified to be highly affected by managerial approaches and actions. In addition,clients play a decisive role, because owner-driven change orders were found as the most crucialcost performance indicator affecting the performance of the engineering and construction phases.The outcome of this study helps practitioners and scholars to understand the phase-based cost andschedule KPIs, and appropriate mitigating strategies to improve the construction performance inEPC phases and save time and money.
