The Construction Safety Audit Scoring System (ConSASS) is an audit tool which provides an independent assessment of the safety and health management system at a worksite.

ConSASS provides a profile of the development status and maturity level of each component of a worksite’s safety and health management system. This helps management to better allocate resources in order to elevate standard and improve the effectiveness in managing a worksite’s safety and health risks. As an assessment tool, ConSASS can be used for cross-comparison between worksites in relation to their effectiveness in managing workplace safety and health risks.
