This article presents a conceptual framework for assessing the maturity of construction control and supervision systems at construction sites. A multi-level assessment model has been developed, integrating the Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation method. A five-level taxonomic system for grading the maturity of regulatory mechanisms in the construction industry is proposed. The procedures for forming a hierarchical structure of assessment indicators, constructing judgment matrices, determining weight coefficients, and applying the fuzzy comprehensive evaluation method to quantify the maturity level of supervision systems are described in detail. The developed methodology represents a universal tool for conducting comparative analysis of construction control and state supervision systems in various national and regional jurisdictions based on objective quantified criteria.

A comparative analysis of quality control procedures for incoming construction materials and products in Russia and China is conducted. The study examines the regulatory and legal frameworks, as well as the specific characteristics of organizing and documenting incoming quality control in both countries. Similarities and differences in approaches to ensuring construction quality, preparation of accompanying documentation, and maintenance of incoming inspection logs are analyzed. The prospects for digitalization of document management processes in the construction industry and the need for further research into the organizational aspects of construction quality assurance are discussed.
