Factors effecting construction contractors' performance: This paper outlines characteristics and their degree of influence on performance level based on a study of royal commission projects executed by 36 different Saudi and joint venture firms in the eastern province of Saudi Arabia

A number of interesting and important aspects have been achieved in this research; in particular, that quality of work should be of major concern to contractors and could become a pre-requisite in any selection process by the client body. Contract documentation should be clear and should not include ambiguous clauses and contradictory documentation, as this only leads to problems for all parties during the contract and a low performance rating from the contractor.
