Abstract:
It is a common practice for the main contractors of Hong Kong
building projects to sublet most of the works to subcontractors.
However, most of the subcontractors complain that they are unable
to perform to their full capacity due to poor coordination of temporary
works and access road to work places etc. Eighteen common
site coordination problems and sixteen essential causes to the problems
were identified from literature and advices from experienced industrial
practitioners. The causes were grouped into three categories:
staffing related causes; technical related causes; and management
system related causes. The contribution, frequency of occurrence and
aggregated importance of the causes on the quality of main contractors’
coordination during the construction stage were ranked through
a questionnaire survey. Unclear job duties was found to be the most
important cause. The results of the survey established that the most
important causes were mainly associated with management systems,
especially communications, rather than staffing or technical related
factors.
