safer. A new worker when oriented will perform tasks of project of good quality sincehe has been shown risks and hazards associated with tasks."Worker working with same crew (friends relatives, etc.) increases quality,productivity, and safety" factor was ranked in the fourth position among workmanshipgroup with RII = 0.717 and was ranked in the 23 rd position among all groups factorsof quality. This result indicates workers working with same crew either friends orrelatives, feel more comfortable than with new crews. This comfortable feelingmotivates workers to collaborate and cooperate on resolving any kind of problems andthus eliminate unexpected hazards. Same crew workers would produce more qualitywork since they would collaborate on performing tasks effectively. Same crewworkers might help solving each other's personal problems thus reducing mentaldispersion which leads to more accidents, less quality, and less productivity."Absence of one or more of workers results in replacement of new worker temporarilywhich decreases quality and increases accidents" factor was ranked in the fifthposition among workmanship group with RII = 0.697 and was ranked in the 29 thposition among all groups factors of quality. This result is relatively relevant to theabove mentioned paragraph of same crews. This result illustrates that when a workeris absent he is replaced by a new one who might not be familiar to crew. Thus, inorder to get familiar to the crew the new worker needs time during which he might beexposed to hazards. The mechanism of task performance would be inconsistent sincea new worker is involved which means that crew would need more time to make thenew worker cope with their productivity and quality in addition to safety."Lack of sufficient workers decreases quality and also decreases safety due topressure on workers" factor was ranked in the sixth position among workmanshipgroup with RII = 0.676 and was in the 33 rd position among all groups factors ofquality. This result indicates sufficient number of workers should be provided at theproject which would increase quality and safety. The lack of worker at the projectwhich might be resulted from the contractor would lead to pressure on workers towork faster and more productively. Working within tight schedules and loaded tasks119
