Abstract
  • The safety of workers in the construction industry is a big concern because of the high number of fatalities and injuries that occur in the industry. Selecting contractors based on safety performance can improve safety and reduce the risks of injuries. However, owners commonly choose contractors based on competitive bidding when the price and the schedule are the most important criteria. This basis for selection means that safety in not given as much importance as the other criteria. The lack of consideration of safety is due in part to the lack of resources and guidance for selecting contractors based on safety performance. This research study tries to fill this gap in practice by developing a tool that owners can use to choose contractors based on safety performance before awarding the project. To develop tool, a literature review and Delphi survey were used. The results from the literature review and Delphi survey revealed 10 indicators and 23 corresponding metrics for contractor safety selection criteria. The 10 indicators and 23 metrics were used to develop a decision-making tool that an owner can use to evaluate construction contractors before awarding the contract. This study contributes to the body of knowledge by revealing indicators and metrics for contractor safety selection criteria and developing a decision-making tool to use by an owner to select contractors based on safety performance. Using this tool will help owners select a safe contractor and therefore the contractor will deliver a safe project.
