Abstract
Cost estimation in construction project is very critical for avoiding cost overrun in the project. This paper aims to provide a basis for improving cost estimation performance in construction through a systematic review of previous studies for last 31 years. The papers have identified a total of 238 construction cost estimation papers in 23 journals. Only 33 papers focused on factors influencing the performance of cost estimation. These papers were then analyzed, synthesized, and summarized in terms of the distribution across countries and citation influences. The factors of cost estimation performance were clustered to several themes with most of the factors in control themes. The factors in control themes are cluttered based on Organizational Control Theory (OCT). However, control themes provide less conceptual basis and dynamic to explain cost estimation performance and relationship among the factors. Therefore, this study reclassified other factors of cost estimation performance with reference to Contingency Theory (CT) and Task-Technology Fit Theory (TTFT). Hence, a new framework with relationship among the factors and cost estimation performance was developed. Further development and research of using the CT and TTFT frameworks were also discussed.
Highlights
The growing importance of construction projects in recent years toward economic and social perspectives has significantly improved cost estimation progress
This paper evaluates construction cost estimation articles published in journals and helps support other construction cost estimation researchers through a classification of cost estimation performance’s factors to new shared dimensions and future research direction on construction cost estimation based on organization control theory (OCT), contingency theory (C.T.) and task-technology fit theory (TTFT)
This paper's primary objectives are to synthesize the factors that are affecting cost estimation performance in construction projects and propose future directions regarding cost estimation performance based on the identified factors
Summary
The growing importance of construction projects in recent years toward economic and social perspectives has significantly improved cost estimation progress. Many researchers have explored the knowledge area of project performance. The construction projects still comprise a high risk to be unsuccessful. The project experience in time overrun is a frequent cause of difficulty in construction projects in developing countries (Aziz, 2013; Mahdi & Soliman, 2021). Malaysia experiences time overrun in construction projects, with 80% of the project have an unnecessary delay in completion (Shehu et al, 2014). Poor cost estimate performance has caused project failure (Project Management Institute, 2018). Cost estimation is one of the primary factors in avoiding project failures such as cost and schedule overruns in construction projects
