Drafting the quantitative and comprehensive checklist for construction phase of Industries and its extension as a strong quantitative method for assessment of ongoing projects

In this study, the goal is to prepare comprehensive and quantitative checklists to determine the potential hazards in construction sites. For this purpose, after the inspection and field study of more than 50 construction projects, two types of technical and managerial checklists were designed. The managerial checklists have been drafted with seven major criteria, which would include three parts of: interviews with operational personnel and managements; observance of the site , installations and conditions of personnel conduct; and study of the related documents. The checklists for technical inspection and qualitative control have also been drafted in 32 important and major subjects. The drafted checklists were quantified by applying a blend of two methods of scoring and “yes, no” technique. Moreover, in order to judge the acceptance or non-acceptance of the risk factor, in each of the studied subjects, four criteria for judgment and decision-making were presented. What’s more, in order to judge the safety status of the whole studied system, an equation was determined to calculate the safety score. Meanwhile, in order to approve the potentials of this method, the results were compared with the results of the ET&BA technique, which according to the experts is one of the best methods for assessment of the safety of construction projects. Following the study and comparison of this method’s results with the results of the ET&BA technique, the final viewpoint of this study was confirmed. In other words, the drafted checklist method is a capable technique in analyses of such systems and it observes different hardware, managerial and drafting risks and human errors in the least amount of time and cost. It will be a rival of ET&BA technique and other methods, and will be a capable replacement for them. Therefore, one can introduce this technique as one of the strongest risk assessment methods in construction phases.
