Abstract & Overview
The factors that affect the quality of building construction projects in Gaza Strip are identified. Nominal Group Technique (NGT) was used at the preliminary stage to identify these factors and to assist in developing a questionnaire to identify and rank these factors and the associated sub-factors. 65 contracting companies and 24 consulting offices participated in responding to the questionnaire. Using factor analysis and stepwise multiple regression analysis, the most important factors affecting the quality of the building construction projects were identified and modeled. Among the most significant factors identified are: characteristics of site layout, experience of site staff, consistency of design documents, the financial power of the contractor, availability of construction materials, subcontractors, political environment, and the control systems used.
