Presentation of a practical framework for performance assessment of HSE in construction contractors

Performance assessment of the HSE-MS in the contractors is a key step in the contractor’s management process and it forms the basis of continuous improvement. Therefore, the present study aims to develop a practical model for the performance assessment of Health, Safety and Environment Management System (HSE-MS) of construction contractors.
In this analytical-practical study, after determining the main factors and indicators related to each of them, the questionnaire was built and then, the process of its validity and reliability were conducted. The importance of the main factors and their indicators were identified by using the questionnaire along with a poll of three groups of HSE experts in a holding company. Afterward, the results of the expert opinions were investigated and the corresponding formulas were used for calculating of the relative importance of main factors and their indicators. The performance indicators score in order to build the model was calculated. At the end, in order to validate the presented model, HSE performance of three large construction contractors in a holding company was evaluated.
developed model was composed of seven main factor and 123 indicators. Total score of contractor performance assessment in the project level can be a range between 80 (very poor performance) and 400 (very good performance) from the perspective of the HSE. The result of performance assessment in project level of three contractors shows that the HSE performance of first contractor was good and both second and third contractors were moderate.
The proposed model can be used by employers of the large organizations to assess their HSE performance of contractors in level project. In addition, with regards to the output of assessing the contractors’ performance, the contractors can be graded according to their HSE performance and was used as an input in the selection of contractors for the future project.
