What are the specific drawings and documents for the preliminary design? Many novices are not very clear about this. In order to help you solve this problem, the following small series will explain it in detail for everyone. Those who have this need can come to learn. I hope you can gain something.

Specific drawings and documents of preliminary design include general design description, general building plan, floor plan, sectional drawing, elevation drawing and project budget estimate.

The preliminary design is the concrete implementation scheme after the proposed project decision-making, and is also the main basis for construction preparation. The contents of preliminary design documents are different due to the different contents and nature of various construction projects. In the case of industrial projects, this should generally include:

Design basis and guiding ideology; construction scale, product scheme, raw materials for production, fuel power consumption and their sources, external cooperation conditions; process flow, main equipment selection; construction of main buildings, structures, public auxiliary facilities and living welfare facilities; general layout and transportation layout

Land occupation and land use; comprehensive utilization, environmental protection,"three wastes" treatment, earthquake resistance and civil air defense measures, production organization labor quota and main technical and economic indicators; construction sequence and time limit; general budget estimate, etc., as well as design drawings and design specifications

Additional information:

Role of preliminary design estimates:

1. Once the preliminary design estimate is approved, it will become the maximum limit of all construction expenses required for the construction project from preparation to completion and delivery, so as to determine the total investment amount of the construction project, as the basis for implementing the investment lump sum system or project construction contract to determine the investment lump sum or contract total cost. No breakthrough shall be allowed in the course of project construction without approval.

2, as the basis for the preparation of fixed assets investment plan.

3. It is the basis for controlling construction drawing design and budget and implementing quota design.

4. The technical and economic indicators of the budget estimate are the basis for analyzing and assessing the rationality and effect of the investment composition of the construction project.

It is the basis for raising construction funds, preparing construction project spending plans, signing investment loan contracts (agreements) and handling investment loans.

6. It is the basis for the preparation of bidding documents and the determination of base price for bidding projects.

7. It is the basis for land acquisition, demolition and construction preparations, equipment processing orders and signing supply contracts (agreements).

8. It is the basis for implementing the economic responsibility system of the construction unit, controlling the appropriation and settlement, and assessing the construction cost.
