The construction industry is one of the main sectors of the Palestinian economy. The contracting companies carry out important construction projects in cooperation with subcontractors. The majority of works in construction projects (such as shuttering, building, plastering, painting, carpentry, and ironmongery works) are implemented by subcontractors through the main contractors[1]. This study aimed at investigating the relationship between the main contractors and their subcontractors. The study used a questionnaire that was administered by contracting companies classified at the Palestinian Contractors Union (in 1st, 2nd and 3rd class building categories) and their subcontractors. The study included the following main topics: 1) Factors used by general contractors for selection of suitable subcontractors. 2) Factors leading to the contractor- subcontractor interface problems. 3) Relationship between the main contractor and the subcontractor related to (Contractual relationship – safety - productivity improvement). The study revealed the important factors used by general contractors for selection of suitable subcontractors include: "adherence of the subcontractor to the contract terms, adherence to time schedule, commitment to prices, good reputation, specialty in certain type of work, commitment to quality and the existence of required equipment and machinery". The study found out that the important factors that cause interface problems include: "Assigning part of the works to new sub contractor without informing the original sub contractor, main contractor's financial problems, delay in contract progress payments, non-adherence to the conditions of the contract, non- adherence of the subcontractor to the time schedule, and lack of construction quality work" The study found that the majority of contracts are written contracts that are usually prepared by the main contractor then shown to the subcontractor, and include a penalty condition to end the contract in case that one of the parties doesn’t comply. Also, the study found out that the responsibility for safety and security is common between the contractor and the subcontractor. The contractor usually considers the previous performance of the subcontractor related to safety issues before selecting him for a project. Finally, the study found out that to improve the productivity, the main contractor should provide all requirements for the subcontractor and prepare the materials and shop-drawings early, while the subcontractor shall be aware of the modern managerial techniques and shall motivate the labors. The study recommended several actions to improve the relations between the contractors and their subcontractors. For example, the contractor should select the subcontractor according to his experience, capabilities, resources and reputation. On the other hand, the subcontractor should do his best to complete the works on time, adhere to all contract terms and conditions and to keep the best quality of work. [1] The terms: “Contractor”, “Main Contractor”, “General Contractor” and “Prime Contractor” shall have the same meaning whenever they are used.
