How to understand the relationship between the bill of quantities and the quota

1) The current quota or the quota to be re-compiled is the basis of the bill of quantities valuation 2) The traditional concept of the quota includes the quantity calculation rules, consumption level, unit price, cost quota items and standards, and now the "quota" in the relationship between the bill of quantities valuation and the quota only refers to the consumption level (standard).

3) The original fixed pricing is based on the consumption level, with the unit price, cost standard, etc. Although the bill of quantities is also based on the consumption level, the unit price, the standard of cost, etc., are no longer stipulated, but by the "macro control, market formation." ”

4) To understand the relationship between the bill of quantities and the quota, there is also a problem, that is, the "separation of quantity and price".

1. The functions are different.

The valuation of the bill of quantities is the tenderer to publicly provide the bill of quantities, the bidder independently or the tenderer to prepare the bottom of the bid and the contract price signed by both parties, the completion of the project settlement and other activities, infiltration is the bidder to complete the bill of quantities provided by the tenderer all the costs required.

The fixed amount pricing method is a pricing model, and its basic characteristics are ** = quota + cost + document provisions, and as a statutory basis for enforcement, whether it is the project bidding to prepare the bottom of the bid or the bidding ** are the only basis for this, the contractor and the contractor share a quota and cost standard to determine the bid floor price and bidding, once the fixed price and the market price are out of touch with the accuracy of the price.

2. The content is different.

The list valuation includes sub-project costs, measure project costs, other project fees, fees, and taxes.

Quota pricing is based on the bidding documents, in accordance with the national construction administrative departments issued by the construction project budget quota of the "quantity calculation rules", directly calculate the direct project cost, and then according to the prescribed calculation method such as the calculation of indirect costs, profits, taxes, summary determination of the cost of construction and installation projects.

3. The role is different.

The quota of construction projects in the fixed pricing mode refers to the standard of labor, materials, machinery and other consumption consumed in the construction process of completing the specified unit of measurement in accordance with the relevant national product standards, design planning and construction acceptance specifications, quality and quantity evaluation standards, and with reference to industry and local standards and representative engineering design and construction data.

The use of the bill of quantities valuation method to determine the project cost can overcome the shortcomings of the budget unit price method, and avoid the strange thing that a project is completed in one year but has to be settled for three years. Because the two methods take different forms of treatment in the hidden unit price of the adjusted engineering quantity, the final settlement of the project is also different.

Quota engineering quantity (fixed quantity pricing system) and list engineering quantity (Ministry of Housing and Urban-Rural Development bill of quantities pricing specification) are two common engineering pricing systems, which are used for cost accounting and cost estimation of engineering projects. They have the following main differences:

1.Pricing method: **

Quota engineering quantity: The quota pricing system is based on the quota, through the detailed provisions of the construction technology, material consumption, labor time and other work in the project, and then multiplied by the corresponding unit price to obtain the cost of each engineering quantity. Quota quantities reflect the scale and cost of different engineering activities.

List engineering quantity: the list pricing system is to divide the project into independent list units according to a certain division, and each list unit corresponds to a schedule, which lists the quantity and unit price of the project, and multiplies the quantity and unit price of the project by multiplying the quantity and unit price. The inventory quantities reflect the detailed details of different engineering activities.

2.Level of refinement: **

Quota engineering quantity: The quota pricing system is relatively detailed, because it needs to make detailed provisions and calculations for the construction process of each project, including the use of various materials, labor, machinery and equipment, and working hours.

List of engineering quantity: the list pricing system is relatively simplified, the project is divided according to a certain list unit, and there is no need to make detailed provisions on the construction process like the fixed engineering quantity, and the pricing unit is usually larger, which is suitable for projects with large engineering quantity, complexity or low type.

3.Management Method:**

Quota engineering quantity: Since the quota pricing system involves more details, it is necessary to control the amount of materials and working hours more strictly in construction management to ensure that the construction is carried out in accordance with the provisions of the quota.

List of engineering quantity: Compared with the fixed amount pricing system, the list pricing system has relatively loose requirements in construction management, and focuses more on the cost control and accounting of the project as a whole.

To sum up, the quota quantity and the list quantity are two different valuation systems, and they have obvious differences in the pricing method, the degree of refinement and the management method. The choice of which pricing system should be decided according to the specific situation of the project to ensure the accuracy and efficiency of cost accounting.

The calculations are completely different.

The main difference between the list of engineering quantities and the quota engineering quantities is: the list engineering quantities are generally the actual consumption of the engineering entity, such as the list engineering quantity of earthwork excavation is the base area of the foundation component multiplied by the earthwork excavation depth, without considering the amount of engineering that needs to be graded and increased during earthwork excavation! The fixed quantity generally includes the actual amount and loss in the physical project, and in general, the quota quantity is greater than the list quantity; Their main difference is determined by two calculation rules.

The fixed quantity calculation is the engineering quantity of each sub-item letter item, and the inventory calculation engineering quantity is the synthesis of the sub-project quantity of a certain part.

In the list of engineering quantity valuation, the comprehensive unit price includes: the fixed unit price, the main talent price difference, and the profit composition of the management fee. Blind cherry blossoms.

The fixed quantity is the basis of the list valuation.

The quantity of the list is based on the quantity of the main grinding spike cluster, such as excavation, which includes excavation, backfilling, transporting soil, etc., and the main quantity of this 1 item is excavation, and the quantity in the comprehensive unit price analysis table of the bill of quantities of the sub-item is equal to the quantity of excavation.

1. List engineering quantity.

The difference with the fixed quantity is that the list quantity is calculated.

It is calculated according to the provisions of the bill of quantities valuation specification. The fixed quantity is calculated according to the calculation rules of the budget quota quantity, so it is completely different.

2. The main difference between the list quantity and the quota quantity is that the list quantity is generally the actual amount consumed by the engineering entity, such as earthwork excavation.

The list of engineering quantities is the base area of the foundation components multiplied by the depth of earthwork excavation, without considering the amount of engineering that needs to be graded during earthwork excavation! The fixed quantity generally includes the actual amount and loss in the physical project, and in general, the fixed quantity is greater than the list quantity, and their main difference is determined by two calculation rules.

Summary. <>

Hello, dear, very happy with your question, what is the connection between the list of engineering quantities and the quota engineering quantities? , to help you find that the list of engineering quantities is greater than the quota engineering quantities, I hope mine can help you. Wishing you good health and a happy mood!

What is the relationship between the list quantity and the quota quantity?

Hello, dear, very happy to you your question, what is the connection between the engineering quantity and the quota engineering quantity of the Bicha pants list? , to help you find out that the amount of simple engineering is greater than the amount of the fixed amount of Qingshou, I hope mine can help you. Wishing you good health and a happy mood!

Dear, the amount of work in the list is greater than the amount of work in the quota.

The quantity of the list and the quantity of the quota module are two completely different concepts, and the calculation of the quantity of the pure list is to calculate the quantity according to the specification of the valuation specification of the bill of quantities of the destruction of the loose bill.

The relationship between the two: it is a multiple relationship. List quantities and quota quantities are not necessarily the same, because the calculation rules are not necessarily the same.

For example, rock scales, earthworks, the list does not consider the slope, and the quota considers the slope. Function: The list of engineering jujube lines is used for list calculation, the fixed quantity is used for fixed pricing, and the fixed quantity is also used in the list price.

<>1. The unit of preparation of engineering quantity is different

The traditional fixed budget valuation method is: the quantity of the construction project is calculated by the tendering unit and the bidding unit respectively according to the drawing. The bill of quantities is invoked:

The quantity of the project is calculated by the tendering unit or entrusted with the project cost consulting qualification unit unified calculation, the "bill of quantities" is an important part of the bidding documents, the bidding units according to the tenderer to provide the "bill of quantities", according to their own technical equipment, construction experience, enterprise cost, enterprise quota, management level of the unit price.

2. The time for compiling the bill of quantities is different

The traditional fixed budget valuation method is prepared after the issuance of the bidding documents (the bidding and the bidder are prepared at the same time or the bidder is prepared first, and the tenderer is prepared later). The Bill of Quantities Act** must prepare a bill of quantities before the tender documents are issued.

The project cost of the traditional budget fixed amount valuation method is composed of direct construction costs, on-site expenses, indirect costs, profits and taxes. The project cost of the bill of quantities valuation method includes the sub-project cost, the measure project cost, other project costs, the regulatory fee and the tax. Includes the cost of completing all the works included in each project; Including the cost of completing each project (excluding fees and taxes); Including the cost of the project content that is not reflected in the bill of quantities and must be incurred in the construction, including the increased cost due to risk factors.

6. The methods used in bid evaluation are different:

Traditional budget fixed amount pricing bidding generally adopts the 100-point scoring method. The bill of quantities pricing method is used to bid, and the reasonable low bidding method is generally adopted, which not only scores the total price, but also analyzes and scores the comprehensive unit price.

7. The project code is different

The traditional budget quota project code is adopted, and the provinces and cities across the country adopt different quota items, the bill of quantities is used to calculate the unified code of the whole country, and the project code is represented by 12-digit Arabic numerals. The first to nine digits are the unified code, of which the first and second digits are the appendix sequence code, the third and fourth digits are the professional engineering sequence code, and the fifth and sixth digits are the branch engineering sequence code. The seventh, eighth and ninth digits are the sequence code of the name of the sub-project, and the ten to twelve digits are the sequence code of the name of the list item.

The first nine digits cannot be changed, and the last three digits are compiled by the list compiler according to the list items set by the project.

8. The contract price adjustment method is different

The traditional methods of adjusting the contract price of the fixed budget include changing the visa, interpreting the fixed quota, and adjusting the policy. The contract price adjustment method of the bill of quantities valuation method is mainly a claim.

The comprehensive unit price of the bill of quantities is generally reflected in the form of bidding, once the bid is won, the basis for signing the construction contract is relatively fixed, and the project settlement is calculated according to the actual amount of work completed by the contractor multiplied by the corresponding unit price in the list. Reduced adjustment port. The traditional budget quota is often used to explain the quota stipulation, and there are policy document adjustments in the settlement; The unit price of the bill of quantities cannot be adjusted at will.

The difference between the fixed quantity and the list quantity is as follows:

Quota quantities and list quantities are different ways to calculate quantities. The quota quantity is calculated according to the construction standards stipulated by the state and the quota indicators listed in the engineering design documents, according to the bill of quantities, construction organization design, etc., and in accordance with a certain unit engineering quantity standard.

The list engineering quantity is calculated according to the corresponding unit price and quantity according to the list items such as materials, components, and labor listed in the engineering design documents. The fixed quantity is calculated according to the indicators listed in the construction standards and design documents. It consists of three main parts:

Workload, quota and bill of quantities per unit of work.

Among them, the workload refers to the amount of labor and material resources that need to be paid to complete a task; The quota refers to the labor, materials, equipment and labor costs required for the workload of each task unit; The bill of quantities per unit of engineering quantity refers to the bill of quantities calculated according to the unit price of the list after the project is divided into several small parts according to the valuation rules.

The fixed quantities calculated from these contents can help engineers more accurately evaluate the human, material and financial resources required for the project. The list quantities are calculated based on the list items in the design document. These items include materials, components, and labor, each with a corresponding unit price and quantity.

The quantities obtained by multiplying these list items by unit price and quantity are called list quantities. Inventory quantities are often used for aspects such as engineering and settlement. The calculation method of the list quantity is more simple and clear, but it is not as accurate as the quota quantity.

The biggest difference between quota quantities and list quantities is the difference in calculation methods. The quota quantity is calculated in accordance with the national standards and the quota indicators listed in the design documents, and the main master should take into account the workload and the bill of quantities per unit of engineering quantity.

The list quantity is calculated according to the list items in the design document, mainly considering the materials, components and labor. Secondly, in terms of use, the fixed quantity is more suitable for engineering evaluation and design, while the list quantity is more suitable for engineering and settlement.

Whether it is a fixed quantity or a list of quantities, it is a very important part of the construction process. By calculating the quantity of the project reasonably, it can help the engineers to more accurately evaluate the resource input required for the project, and at the same time, it can also avoid some unnecessary waste.
