From planned construction to completion and operation, an engineering construction project generally goes through three stages: construction decision-making, construction implementation and delivery. The main steps are:
（1） Project Proposal
According to the requirements of the long-term national economic and social development plan, industrial planning and the urban planning of the construction unit, the project legal person prepares and submits the project proposal for engineering construction after investigation, prediction and analysis according to the development needs of the unit.
(2) Feasibility study report
After the approval of the project proposal, the project legal person entrusts a professional writing agency with corresponding qualifications to conduct a comprehensive analysis, demonstration, scheme comparison and recommend the best scheme for the feasibility of the proposed project in terms of technology, engineering, economy and external cooperation conditions.
(3) Preliminary design
Lanzhou Feasibility Study Report After approval, the project legal person entrusts a qualified design unit to prepare the preliminary design according to the requirements of the approved feasibility study report. After the preliminary design is approved, the design budget estimate is the maximum limit of the project investment, which shall not be broken without approval.
(4) Construction drawing design
After the preliminary design is approved, the project legal person entrusts a qualified design unit to organize the construction drawing design according to the approved preliminary design.
(5) Annual investment plan
After the approval of the project proposal, feasibility study report and preliminary design, apply to the competent department for inclusion in the investment plan. Lanzhou Project Proposal compose
(6) Commencement report
(7) Completion acceptance
It is necessary to control the selection of design scheme and the cost of preliminary design estimate with investment estimate price; Design and revise the estimated cost by using the estimated cost control technology; The engineering construction project must be properly used, and the construction drawing design and budget cost shall be controlled by the estimated cost or the revised estimated cost. In order to reasonably use human, material and financial resources and achieve better investment benefits.
