What stages can engineering design generally be divided into?

including planning, evaluation, decision-making, design, construction and completion acceptance.

1. Planning and decision-making stage

The decision-making stage, also known as the pre-construction stage, mainly includes the compilation of project proposals and feasibility study reports. For government-invested projects, compiling project proposals is the initial stage of project construction.

2. survey and design stage

survey process: complex projects are divided into two stages: preliminary survey and detailed survey. Provide practical basis for design.

design process: it is generally divided into two stages, namely, preliminary design stage and construction drawing design stage. For large and complex projects, technical design stage can be added after preliminary design according to the characteristics and needs of different industries.

3. Construction preparation stage

The main contents of the construction preparation stage include: establishing a 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.

4. Construction stage

The construction project can only be started after it meets the construction conditions and obtains the construction permit. The new start-up time of the project depends on the first formal ground breaking and slotting time of any permanent project specified in the design documents.

5. Production preparation stage

For productive construction projects, before they are completed and put into production, the construction unit should organize special teams or institutions in a timely manner to make production preparations 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 construction stage to operation.

6. Completion acceptance stage

The completion acceptance of the project 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 turned into production and use. After the acceptance, the construction unit prepares the final accounts 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 and operation 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.
