In order to ensure that related enterprises occupy a large share in the market, enterprises adopting EPC mode often adopt closed-loop management, including design, procurement and construction, instead of undertaking separate external contracting for the construction process. Based on this background, this paper studies and expounds the concrete measures to strengthen the management of EPC contracting mode, and improves the economic and social benefits of engineering enterprises.展开更多

Controlling the material procurement costs of natural gas distributed energy projects is a process of establishing, reviewing, monitoring and analyzing costs. The cost management of the natural gas distributed energy project by the construction unit can effectively guarantee the economic benefits obtained in the construction process, and can reduce the procurement cost through the management of the material procurement cost, thus reducing the total construction cost and improving the core competitiveness of the enterprise. Therefore, the construction unit should strictly control the material cost expenditure in the process of engineering construction to improve the efficiency of the enterprise, which is the key to ensure the continuous development of the enterprise.展开更多
