Research on Evaluation of Building Construction Safety Supervision Ability of Third-Party Enterprise under Purchase Service Mode

With the continuous development of the construction industry, the quantity and quality of government construction safety supervision staff cannot be matched with the increasingly complicated safety supervision situation, resulting in loopholes in safety supervision. The application of purchase service mode in construction safety supervision has greatly exerted the professional advantages of third-party enterprises, and effectively solved the outstanding problems of insufficient safety supervision ability and weak professional level of the relevant government departments. Based on the bibliometrics and expert interviews, this paper establishes a third-party enterprise building construction safety supervision ability evaluation index system. Based on the index system and the OPM3 developed by PMI, this article constructs a safety supervision capability maturity evaluation model for the third-party enterprise. The model, on the one hand, guides the government to evaluate different companies, and on the other hand provides a path of effort for enterprises to improve its own safety supervision capability.
