Why is the Standard for Valuation with Bill of Quantities of Construction Projects issued?

The increase in the number of 1. clauses covers the expansion of content and the wide range of use.

(1) Increase in the number of clauses: the number of clauses in the new code has increased from 45 in the original pricing code to 137, with an increase of 92, of which the mandatory clauses have been increased from 6 to 15, and the appendix has been increased from 5 to 6. The mandatory provisions of China engineering construction standards are technical regulations, which will further strengthen the implementation of the standards. And added a very practical "provision description".

(2) Expanding the coverage: integrating the whole process of engineering valuation technology and management: the early stage (controlling the bidding price, compiling the bidding quotation, and agreeing the contract price when signing the engineering contract); Mid-term (engineering quantity measurement and price payment, claim and on-site visa; Adjustment of project price); Later stage (completion settlement, project pricing dispute settlement). However, the old norms are only mainly used to regulate the pricing behavior of bidding bill of quantities.

(3) Wide scope of application: The new specification is applicable not only to all construction projects invested by state-owned funds, but also to projects invested by non-state-owned funds. In addition to some links, the new specification is also applicable to the pricing of engineering projects compiled by quota pricing method.

2. Increase the number of lists and the elements they contain.

The original "Specification" includes three parts: partial bill of quantities, measure project list and other project list. The bill of quantities in the new specification includes five parts: partial bill of quantities, measure project list, other project list, expense project list and tax project list.

The new "Code" stipulates five elements that constitute the partial bill of quantities-project code, project name, project characteristics, measurement unit and engineering quantity. These five elements are indispensable in the composition of the partial bill of quantities, that is, from the original "four unified four elements" to "five elements"

3. Changes in measures and projects.

In the new code, the concrete, reinforced concrete formwork, support and scaffolding included in the original measures are deleted, and the original four items of environmental protection, civilized construction, safe construction and temporary facilities are merged into "safe and civilized construction"; Construction drainage and precipitation are divided into two items; Two new items are added: "construction in winter rainy season" and "underground facilities above ground and temporary protective facilities for buildings".

Old specifications:

1. General project

1. 1 environmental protection

1.2 civilized construction

1.3 Safety construction

1.4 temporary facilities

1.5 night construction

1.6 secondary treatment

1.7 entry, exit and dismantling of large mechanical equipment

1.8 concrete, reinforced concrete formwork and support

1.9 scaffolding

1. 10 completed project and equipment protection

1. 1 1 construction drainage and precipitation

New specification

Serial number project name

1 Safe and civilized construction (including environmental protection, civilized construction, safe construction and temporary facilities)

2 night construction

3 secondary handling

4 Winter rainy season construction

5. Entry, exit and installation of large mechanical equipment

6 construction drainage

7 Construction dewatering

8. Underground facilities on the ground and temporary protection facilities for buildings

9 completed project and equipment protection

4. Changes in measures and project pricing methods

(1) Items whose quantity can be calculated:

Typical is the formwork project of concrete pouring, and the engineering quantity can be calculated. The comprehensive unit price should be adopted for the measures applicable to the partial bill of quantities.

(2) Projects not suitable for calculating quantities:

The occurrence and amount of its expenses are related to the use time, construction method or more than two processes, and have little to do with the actual amount of the physical project. Usually large and medium-sized construction machinery, temporary facilities, etc. , priced by "project", should include all expenses except fees and taxes.

(3) Safety and civilized construction measures

It should be priced according to the provisions of the national or provincial and industrial construction departments, not to mention as a competitive fee.

5. Adjustment of other project list

(1) Provisional amount: established due to price adjustment of some unpredictable and uncertain factors.

(2) Provisional valuation: refers to the amount provided by the tenderee in the tender documents from the tender stage to the finalization of the contract agreement, which is used to pay the inevitable value but the price cannot be determined temporarily, as well as the amount of professional projects.

(3) Daywork: set up to solve the problem of pricing sporadic work on site. Day-counting workers should measure the working hours, the quantity of materials and the machine shifts of construction machinery consumed in completing sporadic work, and make pricing and payment according to the unit price of the items used in the day-counting table.

(4) General contracting service fee: The tenderer will estimate the fee according to the bidder's bid quotation and pay it to the tenderer.

6. Formulation of tender control price.

The new "Valuation Code" and its clause 4.2 point out that "tender control price" is used in the process of project bidding and contracting. The project cost shall be calculated by the tenderer according to the relevant pricing regulations. Its function is the highest price limit adopted by the tenderer to contract the bidding project, and in some places it also becomes the stop price and budget control price. The role of the tender control price determines that the tender control price is different from the pre-tender price and does not need to be kept secret. In order to reflect the fairness and justice of bidding. In order to prevent the tenderer from deliberately raising or lowering the project cost, the tenderer shall truthfully announce the tender control price in the tender documents, and shall not raise or lower the compiled tender control price. At the same time, the tenderer shall report the tender control price to the project cost management institution where the project is located for future reference.
