Professional Design

[Professional term should be design estimate] generally refers to the economic document of all construction costs prepared and determined by the design unit from preparation to completion and delivery according to preliminary investment estimates, design requirements and preliminary design drawings or expanded preliminary design drawings in the preliminary design and expansion preliminary design stages, according to the estimated budget quota or estimated budget indicators, various cost quotas or fee standards, the natural, technical and economic conditions of the construction area and the budget price of equipment and materials, or with reference to similar project budget (final) account documents
Design budgeting method:

The preparation of design budgeting depends on the depth of design, the completeness of the information and the requirements for the accuracy of the budget estimate. When the design data is insufficient, and only the construction site, construction scale, individual project composition, process flow and main equipment selection, as well as the general basis of the building and structural scheme, etc., can be prepared on the basis of the budget or final account of similar projects, after analysis, research and adjustment coefficient; If there is no information on similar works, the budget estimates are used to prepare them; When the design can provide detailed equipment list, pipeline route diagram, building and structural types and construction technical requirements, etc., it is prepared according to the estimated budget quota and cost indicators.

Unit project preparation

1, budget estimate fixed amount

method 1), list the project name of the sub-project or expanded sub-project in the unit project, and calculate its quantity.

2) Determine the estimated fixed unit price of each sub-project.

3) Calculate the direct engineering cost of the sub-items, and get the total of the direct engineering costs of the unit.

4) Calculate the measure fee according to the relevant regulations, and get the total direct cost of the unit project.

5) Calculate indirect costs and taxes according to certain fee standards and calculation bases.

6) Calculate the estimated cost of the unit project.

7) Calculate the economic and technical indicators of unit construction projects.

2. Budget estimate index method When the design depth is not enough to accurately calculate the engineering quantity, and the engineering design technology is relatively mature and similar project budget estimate indicators can be used, the budget estimate index method

can be used.

Since the technical conditions of the proposed project (design object) are often different from the estimated budget indicators for similar projects, and the prices of equipment, materials, labor, etc. in the year in which the proposed indicators are prepared will not be the same as the local prices at the time of the proposed project, adjustments must be made.

1) Adjust when there is a local difference between the structural characteristics of the design object and the estimated budget index.

2) Adjustment of equipment, labor, materials, and mechanical shift costs.

3. The budget method

of similar projects uses the engineering cost data of completed projects or projects under construction with similar technical conditions to design objects to prepare the budget estimate method for the design of proposed projects.

The preparation method

of the project budget of equipment and installation unit 1. Equipment purchase cost estimate

Equipment purchase cost = original equipment price + equipment miscellaneous cost 2. Equipment installation project cost

estimate preparation

1. Budget unit price method. When the preliminary design is deep and there is a detailed equipment list, the installation project budget can be prepared directly according to the fixed unit price of the installation project budget, and the accuracy is high.

2. Expand the unit price method. When the preliminary design depth is not enough, the equipment list is incomplete, only the main equipment or only the weight of the complete set of equipment, the comprehensive expanded installation unit price can be used to prepare the estimate.

3. Equipment value percentage method. When the preliminary design depth is not enough, only the factory price of the equipment without detailed specification weight, the installation fee can be calculated as a percentage of the equipment cost. It is often used for stereotyped products and general equipment products with little price fluctuation.

Equipment installation fee = original price of equipment× installation rate (%)

4, comprehensive tonnage index method equipment installation fee = equipment tonnage × equipment installation fee index

per ton (yuan/ton).

Individual project

1, preparation instructions. It is listed in front of the comprehensive budget estimate, and its contents include:

1) project overview (nature of construction project, characteristics, production scale, construction period, construction location, etc.)

2), preparation basis. Including the state and relevant departments of the prescribed design documents.

3) Compilation method.

4) Other necessary instructions.

2. Comprehensive budget estimate. It shall be prepared in accordance with a uniform format prescribed by the State or ministry.

1) Project composition of the comprehensive budget statement;

2) Cost composition of the consolidated budget statement.
