What are the compilation methods of construction project budget estimate?

In order to ensure the smooth progress of the construction project, it is necessary to make relevant plans in the construction process, and then implement them as planned in the construction process, so as to better ensure the engineering quality.

The preparation method of construction project budget includes:

1) quota calculation method: also known as the expanded unit price method or the expanded structure quota method-the preliminary design is required to reach a certain depth and the building structure is relatively clear;

2) Estimation index method: When the preliminary design depth is not enough to accurately calculate the engineering quantity, similar engineering estimation indexes can be adopted;

3) Similar project budget method: it is applicable to the preliminary design of the proposed project and the design of the completed or rebuilt project. There is no available budget estimate index, but the structure and price difference must be adjusted.

The preparation method of equipment and installation project budget includes:

1) Budget unit price method: the preliminary design is in-depth and there is a detailed equipment list;

2) Expanding the unit price method: the preliminary design depth is not enough, and the equipment list is incomplete;

3) equipment percentage method: when the preliminary design depth is not enough, only the ex-factory price of equipment without detailed specifications and weight, it is often used for shaped products and general equipment with little price fluctuation;

4) Comprehensive tonnage index method: When the equipment list provided in the preliminary design consists of specifications and weights, it is often used for installation calculation of non-standard equipment and imported equipment with large price fluctuation.

Difference between project budget estimate and budget

1. Different preparation units: the budget estimate is prepared by the design unit or the cost consulting unit, and the design, construction and cost consulting units can prepare the budget.

2. Different preparation basis: the budget estimate is prepared according to the preliminary design documents and the budget is prepared according to the construction drawing design documents and the budget estimate quota.

3. Different degrees of accuracy: the budget estimate is general and low in accuracy, with a deviation of 5%- 10% from the actual situation, while the budget is more detailed and high in accuracy, with a deviation of 3%-5% from the actual situation.

4. Different functions: the budgetary estimate is the basis for determining and controlling the investment amount of the project, for optimizing the design scheme, and for bidding and general contracting of the construction project; Budget is the basis for determining the cost of unit projects and individual projects, bidding, signing construction contracts and final settlement, and the basis for banks to allocate project prices.

Legal basis:

Article 577 of the Civil Code

If one party fails to perform the contractual obligations or fails to meet the contractual obligations, it shall be liable for breach of contract, such as continuing to perform, taking remedial measures or compensating for losses.

Article 80 1

If the quality of the construction project is not in conformity with the contract due to the reasons of the builder, the employer has the right to require the builder to repair, rework or rebuild free of charge within a reasonable period of time. If the delivery is overdue after repair, rework or reconstruction, the builder shall bear the liability for breach of contract.
