This paper discusses the significance of the collaborative development of construction project management and construction technology. It analyzes issues in their cooperation, especially in waste-to-energy projects, which face technical complexity and management challenges. It also explores technology-driven efficiency opportunities, process re-engineering, and various decision-making models. Case studies illustrate their application, and synergy efficiency indicators and lifecycle impact assessment are used for evaluation. Finally, it proposes implementation roadmaps and intelligent collaboration platforms for future research.
