As conceived, the current scope of safety management systems is comprehensive and more appropriate for large companies, leaving the issue of a cost-effective construction safety management system for small and medium-sized projects unresolved. The audit of safety management systems is also problematic. Singapore has promoted the Construction Safety Audit Scoring System (ConSASS) as a standard audit tool to conduct an independent safety management system audit and to provide comparable audit results across multiple construction worksites. However, ConSASS has several shortcomings as an audit tool that also make it unsuitable to use in the further development of the audited system. This paper proposes a two dimensional framework ConSASS-2D to guide the design, audit and planning of a construction safety management system. ConSASS-2D consists of grouped process areas with each process area structured by goals and supporting practices. The first dimension is characterized by increasing capability levels and provides a systematic and logical basis for the design and audit of individual process areas. The second dimension of ConSASS-2D improves a safety management system by addressing groups of process areas to improve the overall qualities of the system in terms of increasing maturity levels. The new framework makes it possible for safety management systems to be scoped for projects of different sizes. The organization of a safety management system along the lines of process areas, goals and supporting practices also makes audit results more consistent. The results of an audit using ConSASS-2D is presented to illustrate how audit results using the capability maturity framework can be used to develop a development strategy for the system.
