Improved safety performances of construction projects require the cooperative endeavors of different parties involved in construction industry, including the project owner, general contractor, subcontractor, A/E firm, etc. The owner, generally the initiator and sponsor of a project, may have greater influence on a project＇s safety than any other participants through personal commitment and participation.
