ut also when the crew does return to work they will be left short-handed andproductivity is often below normal (Hinze, 1997)."Main contractor would hire more subcontractors to increase productivity, creatinglack of coordination which leads to less safety attention" factor was ranked in thesecond position among subcontractors group with RII = 0.643 and was ranked in the17 th position among all groups factors of productivity. This result shows that hiringlarge number of subcontractors exposes the project to poor coordination which wouldbe at the expense of safety. Having more subcontractors does not necessarily meanmore productive environment because a crowded workplace is said to be lessproductive and more risky."Subcontractor's lack of safety concerns, decreases productivity" factor was ranked inthe third position among subcontractors group with RII = 0.627 and was ranked in the19 th position among all groups factors of productivity. This result shows that unsafesubcontractors are probably unproductive. General contractor is generally aware pfthe subcontractors' safety behavior during selection process. Unsafe subcontractorsare frequently exposed to corrective actions because of errors caused by them whenthey are exposed to accident. Productivity decreases because workers would bestressed when they feel that subcontractor is not aware of their personal safety."When subcontractor is assigned specific tasks, accidents increase" factor was rankedin the fourth position among subcontractors group with RII = 0.561 and was ranked inthe 21 st position among all groups factors of productivity. This factor holds the lowestrank within its relevant group and extremely low rank within overall rank ofproductivity. This result shows that respondents did not support the idea that hiringsubcontractors for specific trades affect safety negatively. Ensuring thatsubcontractors execute an effective safety and health program is one of the thorniestissues confronting general contractors.
