摘要

Project cost is one of the most important criteria of success of project and is of high concern to those who are involved in the construction industry. However, studies show that rarely projects are complete within stipulated budget. This study is focusing on identification of significant causes affecting construction cost in MARA large projects. This paper presents the results of a questionnaire survey conducted among the personnel of Project Management Consultant (PMC). Data was analyzed with statistical tools to determine the rank of factors affecting construction cost. It is concluded that cash flow and financial difficulties faced by contractors, contractor's poor site management and supervision, inadequate contractor experience, shortage of site workers, incorrect planning and scheduling by contractors are most severe factors while changes in scope of project and frequent design changes are least affecting factors on construction cost. Spearman correlation analysis showed that incorrect planning and scheduling by contractor has strong positive relationship with contractor’s poor site management and supervision, inadequate experience of contractors has strong positive relationship with incorrect planning and scheduling; and contractor’s poor site management and supervision, changes in scope of project has strong positive relationship with frequent design changes; and vice versa.
