In the context of the "dual carbon" goals and digital transformation, technological innovation has become the core driving force for enhancing the management efficiency and overall benefits of building projects. Digital tools (BIM, IoT, AI) are reshaping design and construction collaboration mechanisms, while intelligent equipment (drones, robots) is optimizing work efficiency and safety. Green technologies (low-carbon materials, waste regeneration) are promoting sustainable development. Dynamic management models drive resource allocation and risk warnings through real-time data, achieving precise control over costs, quality, and schedules, with project comprehensive benefits improving by 20–30%. Issues such as insufficient technology integration and high application barriers for small and medium-sized enterprises urgently need to be addressed. Accelerating the industry's transition towards high-efficiency and low-carbon directions requires policy support, the construction of a technological ecosystem, and the cultivation of versatile talent.
