Risk-based approach to control requirements in construction supervision

Introduction. The relevance of the study is due to the need to improve the efficiency of control and supervisory activities under the transition to a risk-based model. The aim of the work is to develop a methodology for forming variable control requirements for inspection programs of civil engineering facilities, differentiated by risk categories. The scientific novelty lies in the integration of analytic hierarchy process and expert assessments to quantify the significance of individual types of work and structural elements. Materials and methods. The methodological basis was the provisions of federal legislation and the criteria for classifying capital construction projects into risk categories. To rank potential violations and determine the weight coefficients of control points, the Analytic Hierarchy Process (AHP) by T. Saaty was applied. The expert data (12 experts from the State Construction Supervision authorities) was processed using specialized software. Results. A correspondence matrix has been developed that allows for the formation of an individual list of control requirements for each risk category of the facility. Key control points for high-risk and medium-risk facilities have been established. The most frequently identified types of violations have been identified and classified, grouped by the degree of impact on safety. Conclusions. The proposed approach allows reducing the administrative burden on bona fide developers and concentrating the resources of supervisory authorities on potentially hazardous facilities. The implementation of the developed methodology into the administrative regulations for the execution of the state function of construction supervision is recommended.
