What are the specific drawings and documents for the preliminary design?

The specific drawings and documents of preliminary design include general design description, general building plan, floor plans, sections, elevations and project budget estimates.

The preliminary design is the specific implementation plan after the decision-making of the proposed project, and is also the main basis for construction preparation. The content of preliminary design documents is also different due to the different construction content and nature of various construction projects. As far as industrial projects are concerned, it should generally include:

Design basis and design guiding ideology; construction scale, product plans, production raw materials, fuel power consumption and its sources, external collaboration conditions; process flow, and main equipment selection ;Construction of main buildings, structures, public auxiliary facilities and living welfare facilities; general plan transportation layout.

Covered area and land use; comprehensive utilization, environmental protection, "three wastes" treatment, earthquake-resistant fortification and civil air defense measures, production organization labor capacity and main technical and economic indicators; construction sequence and period; general budget, etc. and Design drawings and design instructions.

Extended information:

The role of preliminary design budget estimate:

1. Once the preliminary design budget estimate is approved, it will become the entire construction cost required for the construction project from preparation to completion and delivery. The maximum amount shall be used to determine the total investment amount of the construction project and serve as the basis for the implementation of the investment contract system or the general contracting of project construction to determine the investment package amount or the total contracting cost. During the project construction process, no breakthroughs are allowed without approval.

2. As the basis for preparing fixed asset investment plans.

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 effectiveness of investment in construction projects.

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

6. It is the basis for preparing project construction bidding documents and determining the minimum bid for bidding projects.

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

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