Abstract:Against the background of accelerating digital transformation in the global construction industry, China's construction engineering sector is facing dual pressures from rising costs and green transition. The full-chain digital solution provided by Shushangyun is the key to solving the above dilemmas. Through technologies such as BIM and the Internet of Things, the integration of design and construction can be realized, converting the traditional 3.2% profit margin improvement space into digital management dividends. In view of the problems existing in the information management of the construction industry, such as system silos, data fragmentation and superficial application, this paper analyzes the collaborative application mechanism of BIM technology, IoT platform and project management system, and constructs a whole-life-cycle digital management system, aiming to improve the refinement and intelligent level of construction engineering management.
