Their opinions on the impact and frequency of each factor were investigated.
The questionnaire offered (59) factors classified in (8) categoriesnamely; legislations, financial and economic, design, contractual, site management, material, labor and equipment.
The factors were ranked according to the highest Relative Importance Index(RII).
The study revealed (10) major factors that are potentially controllable by main contractors namely; labor productivity, sub-contractors and suppliers performance, equipment productivity, site organization and distribution of equipment, experience and training of project managers, scheduling and control techniques, planning for materials supply, planning for equipment supply, materials delivery and planning for skilled labor recruitment.
