Abstract

In Hong Kong, it is a common practice for main contractors to divide the projects into work packages by trade and sublet to sub-contractors. The interaction between sub-contractors and main contractors is an important determinant to the success of a project. However, there is an increasing complaint from sub-contractors that they cannot perform to their full capacity because of poor site-coordination by main contractors. This paper aims to identify and categorize the common site coordination problems in Hong Kong Building Projects. Thirty- eight common site-coordination problems were identified through literature and they were classified into six main categories of problems: Construction document; Site management; Site layout; Equipment support; Material support; and Preparation of site area. A questionnaire survey was conducted to analyze the frequency of occurrence (F.I.) and degree of severity (S.I.) of the problems to the projects. The aggregated importance (IMP.I.), taking into account of the frequency of occurrence and degree of severity, of problems on sub-contractors’ time performance were ranked. Frequent changes of construction works was found to be the most important site coordination problem. Most of the important problems caused the delay to subcontract works were primarily related to Construction document.
