1. Undertake business and sign contract 2. Construction preparation 3. Formal construction 4. Completion acceptance, handover and settlement stage

The owner entrusts engineering tasks such as survey, design, equipment supply, civil engineering, installation, and decoration to different parties respectively. same contractor. Each contractor signs a contract with the owner and is responsible to the owner.

There are three main payment methods for PPP projects: government payment, user payment and feasibility gap subsidy.

Four controls: progress control, quality control, cost control, safety control Five management: contract management, green construction and environmental management, information and knowledge management, risk management 1. Coordination: communication and coordination

1) Project contractor ① State agencies and other administrative departments; ② Domestic and foreign enterprises; ③ General contractors, including project general contractors and construction general contractors. 2) Project contractor ① Survey and design unit; ② Supervision unit; ③ Construction unit; ④ Material and equipment suppliers; ⑤ Processing and transporters.

① Project management by the general contractor of the project ② Project management by the construction party ③ Project management by the owner (construction supervision) ④ Project management by the designer ⑤ Project management by the supplier ⑥ Project management by the construction management department
