Part of the bill of quantities of quantities of works project code is set at five levels of coding, each level of coding is set as follows:
①The first level is divided into two bits (ー, two bits), indicating that the project classification sequence code: 01-house building and decoration works; 02-antique building works; 03-general installation works; 04-municipal works; 05-gardening and landscaping works; 06-mining works; 07-construction works; 08-urban works; 07-urban works; 08-urban works; 08-urban works. Structures Engineering; 08-Urban Railway Transportation Engineering; 09-Demolition Engineering. Later into the national standard of professional engineering code and so on.
② The second level of two (three, four), said the professional engineering sequence code.
③The third level is divided into two (five, six), indicating the sequence of divisional engineering code.
④The fourth level is divided into three bits (seven, eight, nine bits), indicating the sequence code of sub-projects.
⑤ The fifth level is divided into three bits (ten, ten ー, ten n bits), indicating the bill of quantities project sequence code. Construction project code structure is shown in Figure 1-1.
When the same bid (or contract section) of a bill of quantities contains more than one unit of work and the bill of quantities is to unit of work as the object of compilation, in the preparation of the bill of quantities should pay special attention to the project code of ten to twelve bits of the setup shall not have re-coded provisions.

2) Characteristics of the items of the bill of quantities of component works shall be described in accordance with the item characteristics of the Specification for Quantity Calculation of Building Construction and Decoration Works GB50854-2013 in conjunction with the actuality of the proposed construction project.
The project characteristics of the bill of quantities is to determine a list of items indispensable to the comprehensive unit price of an important basis, in the preparation of the bill of quantities, must be accurate and comprehensive description of the project characteristics. But some of the project features with the text is often difficult to accurately and comprehensively describe clearly. Therefore, in order to achieve the standardized, concise, accurate and comprehensive description of the requirements of the project characteristics, in the description of the bill of quantities of quantities of project characteristics should be carried out in accordance with the following principles:
1) the contents of the project characteristics should be described in accordance with the provisions of the appendix, combined with the actual construction of the proposed project, to meet the need to determine the comprehensive unit price.
② If the use of standard drawings or construction drawings to meet all or part of the requirements of the project characterization, project characterization can be used directly in detail xx drawings or xx drawings number. Can not meet the requirements of the project description of the characteristics of the part, the text should still be described.
(3) the quantity calculation rules and unit of measurement to set the subfield can know the item single work positioning out
1) the amount of work listed in the bill of quantities should be calculated according to the "housing construction and decoration works quantity calculation specification" GB50854-2013 the amount of work specified in the calculation rules.
2) The unit of measurement of the quantity list of works in sub-parts shall be determined in accordance with the unit of measurement stipulated in the Specification for Calculation of the Quantity of House Construction and Decoration Works GB50854-2013.
(4) Other Related Requirements
1) The cast-in-place concrete project includes the content of formwork work in the "work content", and at the same time, the cast-in-place concrete formwork project is listed separately in the "measure items". In this regard, by the bidder according to the actual situation of the project selection, if the bidder in the list of measures for the project did not fill in the list of cast-in-place concrete formwork project, that is, cast-in-place concrete formwork project is not listed, cast-in-place concrete project should be included in the comprehensive unit price of the cost of formwork works.
2) of precast concrete components produced on site to prepare the project, "work content" including template project, no longer listed.

3. Other items list
Other items list should be in accordance with the provisional amount, provisional estimate, day labor, general contracting services.
(1) provisional amount
Provisional amount is the bidder temporarily and included in the contract price of a sum of money. Regardless of the form of contract, the ideal standard is that the price of a contract is the final price of its completion, or at least the two should be as close as possible. China's provisions of the government investment projects to implement the management of budget estimates, approved by the project approval department of the design estimate is a rigid indicator of engineering investment control, even if the commercial development projects also have the cost of pre-control issues, otherwise, can not be relatively accurate prediction of the return on investment and scientifically sound investment control. However, the characteristics of engineering construction itself determines the design of the project needs to be continuously optimized and adjusted according to the progress of the project, the owner's demand may change with the progress of engineering construction, engineering construction process there will be a number of unforeseen, undetermined factors. Digest these factors will inevitably affect the adjustment of the contract price, provisional sums of money in response to such inevitable price adjustment and the establishment in order to achieve the goal of rationally determining and effectively controlling the cost of the project.
There is a misconception that the provisional sum is included in the contract price belongs to the contractor (the winning bidder) all. In fact, even if the lump-sum lump-sum contract, is not included in the contract price of any amount belongs to the winning bidder, whether it is the amount due to the winning bidder depends on the specific contract agreement, provisional amount from the definition of the beginning of the definition of the clear, only in accordance with the contract agreement procedure actually occurred, in order to become the winning bidder's entitlement to the amount of money, into the contract settlement price. The balance of the provisional amount after deducting the amount actually incurred still belongs to the bidder. The establishment of the provisional sum does not guarantee that the contract settlement price will not appear again over the contract price, whether or not over the contract price depends entirely on the accuracy of the provisional sum of money predicted and the construction process of the project whether there are other events not predicted in advance.
(2) provisional estimate
Provisional estimate refers to the bidding stage until the signing of the contract agreement, the bidder in the bidding documents provided for the payment of the materials and professional works that are bound to occur but the price can not be determined for the time being the amount of money. This includes the tentative price of materials, tentative unit price of engineering equipment, and tentative price of specialized works.
For the convenience of contract management and pricing, need to be included in the bill of quantities of engineering items in the comprehensive unit price of the provisional estimate of the best just the cost of materials, in order to facilitate the bidders group price. For professional engineering tentative price should generally be a comprehensive tentative price, including in addition to fees, taxes, other than management fees, profits and so on.
(3) day labor
Day labor is set up to solve the pricing of sporadic work occurring on site. Most of the common international standard contract terms and conditions have established the Daywork pricing mechanism. Daywork measures the labor hours, material quantities, and construction machinery units consumed to complete the sporadic work, and pays the unit price of the applicable item as reported in the Daywork form. The so-called sporadic work applicable to day labor generally refers to additional work beyond the contractual agreement or due to changes, which does not have corresponding items in the bill of quantities, especially those additional work whose time does not allow for a price to be agreed upon in advance.
(4) General Contractor's Service Fee
General Contractor's Service Fee is incurred and paid to the General Contractor in order to solve the problem of the bidder's contracting of specialized works and supplying of materials and engineering equipment on its own as permitted by the laws and regulations, as well as the need for the General Contractor to provide coordinating and cooperating services for the specialized works contracted, and to provide receiving, dispatching and custodianship services for the A-supplied materials and engineering equipment, and to carry out the management of the construction site. Costs incurred and paid to the general contractor. The Bidder shall anticipate the cost and pay it to the Bidder in accordance with the Bidder's bid.
4. List of fees and charges
1) The list of fees and charges shall be listed in accordance with the following:
1) Social security fees: including pension insurance fees, unemployment insurance fees, medical insurance fees, industrial injury insurance fees, and maternity insurance fees.
② housing fund.
③Engineering sewage charges.
2) Items appearing that are not listed in Article 1) shall be listed according to the regulations of the provincial government or relevant provincial departments.
(Note: According to the Circular of the Ministry of Finance, the National Development and Reform Commission, the Ministry of Environmental Protection, and the State Oceanic Administration on Matters Relating to the Suspension of Sewage Discharge Fees and Other Administrative Fees (Cai Shui [2018] No. 4), the engineering sewage charges that were originally included in the fees and charges have already ceased to be levied in January 2018.)
