The decision-making stage, also known as the pre-construction stage, mainly includes the preparation of project proposal and feasibility study report. For government-invested projects, the preparation of project proposal is the initial stage of project construction. Its main function is to recommend construction projects, so as to select construction projects according to the natural resources and market forecast of a certain region or department.
2. Survey and design stage
Investigation process: complex projects are divided into two stages: preliminary investigation and detailed investigation. Provide practical basis for design.
Design process: generally divided into two stages, namely, preliminary design stage and construction drawing design stage. For large-scale complex projects, technical design stage can be added after preliminary design according to the characteristics and needs of different industries.
3, the construction preparation stage
The main contents of the construction preparation stage include: the establishment of project legal person, land acquisition, demolition, "three links and one leveling" and even "seven links and one leveling"; Organizational materials, equipment orders; To go through the procedures for quality supervision of construction projects; Entrusted project supervision; Prepare necessary construction drawings; Organize construction bidding and select the best construction unit; Handling construction permits, etc. According to the provisions, make good preparations for construction, and after the construction conditions are met, the construction unit applies for construction and enters the construction and installation stage.
4. Construction stage
The construction project can not be started until it meets the conditions for commencement and obtains the construction permit. The new commencement time of the project depends on the first official groundbreaking and slotting time of any permanent project specified in the design documents. If slotting is not needed, the official piling will be the starting time. Railways, highways, reservoirs, etc. Commencement of earthwork is the official commencement time.
5, production preparation stage
For productive construction projects, before they are completed and put into production, the construction unit shall organize special teams or institutions in time to make preparations for production in a planned way, including recruiting and training production personnel; Organize relevant personnel to participate in equipment installation, commissioning and project acceptance; Implement the supply of raw materials; Establish production management institutions and improve production rules and regulations. Production preparation is an important work from the construction stage to the operation stage.
6, the completion acceptance stage
The acceptance of project completion is an important step to comprehensively assess the construction achievements, check the design and construction quality, and it is also a sign that the construction project is put into production and use. After the acceptance, the construction unit prepares the final accounts for completion, and the project is officially put into use.
7. Assessment and evaluation stage
Post-evaluation of construction project is a technical activity that systematically evaluates the whole process of project decision-making, design and construction, completion and production after the project is completed and put into production and operation for a period of time. It is an important content of fixed assets management and the last link of fixed assets investment management.
Extended data
According to the long-term plan of national economic development, after preliminary investigation and study, the project sponsor will prepare the project proposal, recommend the proposed project to the investment management department according to the investment management authority, and include it in the pre-construction work plan after approval. The competent investment department shall comprehensively balance the proposed projects, select a number of necessary and promising construction projects when the conditions are ripe, and entrust the project organizers to design or engineering consulting units for feasibility study.
For a feasible project, after pre-examination, modification, review and evaluation, a feasibility study report is put forward, submitted to the competent investment department for examination and approval, and then the project is established. The annual construction plan can arrange for the preliminary work of engineering design and construction. The project organizer should set up or designate competent construction units to negotiate, make an appointment or sign various agreements and contracts, and do a good job in a series of preparatory work such as survey and design, site selection, land acquisition and fund raising.
