The General Office of the State Council first mentioned the concept of "Full-Process Engineering Consulting" in the "Opinions on Promoting the Sustainable and Healthy Development of the Construction Industry" in 2017, that is, with the construction supervision companies as the main body, based on the construction supervision stage, to the upstream and downstream of the construction supervision stage expand and extend, carry out project consulting, cost consulting, bidding agency, project management, engineering design, and other diversified consulting service business. This is the first time that the country has clearly proposed this concept in the entire industrial chain of construction projects. It aims to meet the needs of the development of the socialist market economy and the internationalization of the construction project market, improve the level of project construction management and consulting services, and ensure project quality and investment benefits. Building Information Molding, referred to as BIM technology, can effectively realize information integration, interaction and collaborative office in the field of construction engineering. Through the integration of project information, the effective use of relevant information in the entire life cycle of project design, construction, operation, and maintenance can be realized. BIM technology has increasingly become a necessary professional skill for relevant engineering and technical personnel. It is used to improve the production efficiency of project construction and optimize the cost and construction period. It is a key technical factor to realize the whole process of engineering consulting.
