What is the difference between budgeted quantities and physical quantities?

The estimated quantity is the quantity calculated according to the construction drawings, while the physical quantity is the quantity of the finished product built on the construction site.

The main difference between the budgeted quantity and the physical quantity is that the calculation rules of the budgeted quantity are calculated in accordance with the calculation rules of the engineering quantity stipulated by the state, while the physical quantity is calculated according to the physical quantity of the drawings. In the construction quantity, the budgeted quantity of most individual projects is equal to the physical quantity.

However, there are some individual projects where the estimated quantity of work and the quantity of physical work are not equal.

For example: the quantity of foundation excavation, the estimated engineering quantity is calculated according to the provisions of the engineering quantity calculation rules, and the foundation excavation does not consider the number of excavation of the slope and the working face, and is calculated by the vertical projection area of the outer edge of the foundation cushion. The physical quantity needs to consider the amount of excavation slope and excavation of the working face.

Another example is the wall masonry project, the hole with less than 300 square centimeters of wall surface in the budgeted quantity does not need to be deducted in the calculation, while the physical quantity needs to deduct the number of holes.

The estimated quantity is an estimate of the project, which is an indefinite value.

The physical quantity is the actual quantity of the project that actually occurred, which is the actual value, and the budget value is only a reference value.

The estimated quantity of construction projects has calculation rules for engineering quantity according to the relevant national requirements and regulations, and the calculation rules are not for a construction project, but the measurement under normal construction conditions of the comprehensive local (generally with the province as the preparation area)! In addition, for the convenience of calculation, to some corners. Small holes are not deducted, etc., (integrated into other subheadings) It is different from the actual amount of a single construction project.

1.Construction drawing budget: It is mainly for construction services for construction.

2.The bill of quantities is calculated according to the calculation rules, the purpose is to make the construction unit understandable.

Specifically: the difference between the pricing characteristics of the bill of quantities and the traditional construction drawing budget valuation.

The pricing of the bill of quantities is the independent pricing of the enterprise. The project reflects the individual cost of the enterprise. The construction drawing budget valuation reflects the average social cost during the project quota preparation period**.

The valuation of the bill of quantities is conducive to truly reflecting and promoting the orderly competition of enterprises, and is conducive to promoting the application of new technologies, new processes and new materials of the project.

The bill of quantities is priced using the comprehensive unit price. It can intuitively and comprehensively reflect the actual situation of the enterprise's completion of divisions, sub-projects and unit projects; Moreover, it is convenient for both parties to calculate, approve and change the project contract, measure and pay and settle the project payment, especially suitable for fixed unit price contracts.

The construction drawing budget valuation adopts the unit price of the project quota promulgated by the state, and the management fee and profit are calculated separately, without considering the risk factors, which can not intuitively and comprehensively reflect the actual situation of the enterprise to complete the division, sub-project and unit project, and the calculation and adjustment of the project contract is more complex, it is difficult to define the rationality, and it is easy to cause disputes between all parties.

The principle of separation of quantity and price. The bidding is based on the bill of quantities, and the tenderer is responsible for the content of the project and the quantity calculated by the posture, and bears the risk of the quantity of the project; According to their own strength and market competition, the bidder shall determine the elements, enterprise management fees and profits, and bear the risk of the agreed scope of the project. The construction drawing budget bidding is calculated by the bidder himself, and the deviation may be the difference in unit price, or it may be the deviation of the quantity, which can not truly reflect the competitive strength of the bidder.

List bidding, unified the amount of work, unified on the basis of the first grade, bidders to avoid the risk caused by the calculation error of the number of projects, so as to truly rely on their own strength to compete for lead.

Combined with enterprise construction technology, process and standards. The technical and commercial bids of the construction drawing budget bidding are prepared separately according to the different standards of the enterprise and the first grade, which cannot support and match each other, and cannot fully and correctly reflect and evaluate the bidder's technical and economic comprehensive capabilities. The unit price composition of the project entity project and the measure project of the bill of quantities bidding can be closely integrated with the technical standard, support and cooperate with each other, which can not only reflect and measure the feasibility, reliability and rationality of the bidding plan from both technical and commercial aspects, but also reflect the comprehensive competitiveness of the bidder.

Summary. The quantity calculation book is a calculation formula for calculating the engineering quantity according to the engineering quantity calculation rules. The project budget is based on the total price obtained in the calculation book, multiplied by the corresponding unit price, plus the corresponding fees.

What is the difference between a quantity calculation book and a project budget book?

The quantity calculation book is a calculation formula for calculating the engineering quantity according to the engineering quantity calculation rules. The project budget is based on the total price obtained in the calculation book, multiplied by the corresponding unit price, plus the corresponding fees.

The quantity calculation book is a calculation formula for calculating the engineering quantity according to the engineering quantity calculation rules. The project budget is based on the total price obtained in the calculation book, multiplied by the corresponding unit price, plus the corresponding fees.

Construction drawing budget: is for the construction of the main construction services, to calculate how much m3 concrete, how much steel bar, is a relatively close to the actual amount + loss of the amount, the bill of quantities, is calculated by the calculation rules, the purpose is to make the construction unit understand, such as the ditch, in the construction drawing budget, to calculate how much soil to dig, how many m3 bricks to build, etc., and the list rules only require you to calculate how much m, the construction unit according to their own strength by yuan m**.

The construction drawing budget is the basis of the list valuation. Only by doing the construction drawing budget, the construction unit can know how to be in the list, and the list is concise and clear, the construction unit understands at a glance, they don't need to know how to do trenches to dig soil, to lay bricks, or something else, they just need to look at the money, how much your family reports, how much his family reports, and then he wants to choose which one. That's it.

First, the role of the two is different:

1. The role of material plan (also known as construction material plan): as the main basis for procurement, ordering and feeding of material department. Namely:

According to the construction material plan proposed by the professional foreman, the material department organizes procurement personnel to purchase and feed materials according to the use time, batch size and difficulty of the materials, so as to prevent the backlog of materials and ensure that the construction can be carried out smoothly.

As the main means of control of the materials department over the materials used by the construction team. The material department controls the distribution of materials to the construction team according to the material specifications, models, quantities, and use time proposed by the professional foreman to prevent waste and damage to the construction personnel.

2. The role of engineering quantity budget: the project valuation is based on the engineering quantity, therefore, the accuracy of the engineering quantity calculation directly affects the accuracy of the project cost and the investment control of the project construction.

The engineering quantity is an important basis for the construction enterprise to prepare the construction operation plan, reasonably arrange the construction schedule, and organize the on-site labor, materials and machinery. The quantity of the project is an important basis for the construction enterprise to compile the statistical report of the project image progress and settle the project price to the project construction investor.

Second, the overview of the two is different:

1. Overview of the material plan: The construction material plan, also known as the engineering material plan, reflects the demand for various materials, products and components that constitute the entity of the construction project, and is an important part of the construction project material plan.

2. Overview of engineering quantity budget: engineering quantity refers to the engineering quantity of each sub-project or structural component expressed in natural measurement unit or physical measurement unit, such as light box, mirror box, and counter measured by "one".

3. The content included in the two is different:

1. The content of the material plan: the management of the material plan refers to the management of economic activities such as ordering, directing, supervising and regulating the ordering, procurement, transportation, distribution, reserve, and use of materials with the plan.

2. The content of the engineering quantity budget: the content of the engineering quantity calculation includes the project list, project code, comprehensive unit price, measure project, reserve, general contracting fee, sporadic cost, consumption quota, enterprise quota, bidding base, bidding, construction project, single project, unit project, branch project, and sub-project.

<> construction drawing budget and bill of quantities are an important part of the project cost, but some new cost personnel are still not clear enough to distinguish between the two concepts.

There are three main differences between the construction drawing budget and the bill of quantities:

First, the nature is different.

1. Construction drawing budget: the construction and installation project budget cost document prepared according to the construction drawings, budget quotas, various fee standards, and the natural and technical and economic conditions of the construction area.

2. Bill of quantities: a detailed list of the names and corresponding quantities of sub-projects, measure items, other items, fee items and tax items of the construction project.

Second, the role is different.

1. Construction drawing budget: The construction drawing budget is the basis for determining the cost of the construction project in the construction drawing design stage, and is an integral part of the design document. The construction drawing budget is the basis for determining the bidding; The construction drawing budget is the basis for controlling the construction cost.

2. Bill of quantities: The bidding and training bill of quantities provides an equal and common basis for bidders' bidding competition; The bill of quantities is the basis for the valuation of construction projects; The bill of quantities is the basis for the payment and settlement of the project; The bill of quantities is the basis for adjusting the quantity and making a claim.

Third, the composition is different.

1. Construction drawing budget: direct costs, indirect costs, profits, taxes.

2. Bill of quantities: direct cost unit price, part cost unit price (also known as comprehensive unit price), full cost unit price (international practice) The full cost unit price is composed of direct costs, non-competitive costs and competitive costs.

Under normal circumstances, the construction drawing budget is calculated according to the current project budget quota, the engineering quantity of the drawings, and the current settlement system, and the construction unit or the construction unit can calculate it by itself; The bill of quantities is only used for bidding, the list is completed by the construction unit and the construction unit, the construction unit issues the sub-project and the quantity, and the construction unit fills in the unit price.

To sum up, the construction drawing budget refers to the first accounting for the construction drawings, and the bill of quantities is one of the best accounting methods.
