How to prepare the bidding control price and the bill of quantities and the workflow for filing the bidding control price? "Construction Project Bill of Quantities Pricing Specifications" stipulates that "Construction projects invested by state-owned funds shall implement bill of quantities bidding. And the bidding control price should be prepared. "? The Guangzhou Urban and Rural Development Commission's "Notice on Standardizing the Establishment of Bidding Control Prices for Housing Construction Projects and Municipal Infrastructure Projects" (Sui Jianshe [2010] No. 564) is the current bidding control price establishment in Guangzhou. specific execution files. ?The tenderer is responsible for the accuracy and completeness of the bill of quantities prepared. The responsibility for setting up the bid control price rests with the tenderer, and the preparation unit and the registered estimator responsible for preparation are responsible for the accuracy and completeness of the control price. . ? Regarding the preparation of the bidding control price and bill of quantities, let’s talk about it from the following aspects: 1 1.1 The significance of improving the quality of preparation? 1.1.1 It helps the bidder to effectively control investment? 1.1.2 It helps the bidder to reasonably prepare the quotation? 1.1.3 Conducive to the settlement and review work of the project 1.2? 1.2.1. Correctly calculate the project quantity? The project quantity is the basic data for the preparation of the bidding control price and the bill of quantities. At present, the budget quotas in Guangdong Province are set according to the construction procedures and techniques. The project contents included in the quota projects are generally single, and the budget quotas stipulate the corresponding engineering quantity calculation rules. The setting of the bill of quantities items in the 08 specification is considered as a "comprehensive entity", which generally includes multiple sub-item projects, and also stipulates the corresponding engineering quantity calculation rules. There are differences in the calculation rules between the two. When calculating engineering quantities based on construction drawings, distinctions need to be made, and the list engineering quantities and their corresponding quota sub-project quantities are calculated separately. The engineering quantity of the list must be calculated strictly in accordance with the calculation rules of the engineering quantity of the list. The engineering quantity of the quota sub-item corresponding to the list item must be calculated according to the engineering quantity calculation rules stipulated in the comprehensive quota, and then converted into the comprehensive unit price of the engineering quantity of the list. ?For example: the calculation rules for the quantity of earthwork works, the list rules and the quota rules are different. ?The provincial station's guidance on the calculation rules for the quantity list for trench excavation: According to the width of the outer edge of the pipe structure (including the foundation and cushion), multiply by The depth of excavation (from the average elevation of the original ground to the height of the trench bottom) is calculated by volume. The filling is calculated based on the excavation list item minus the foundation, the buried volume of the structure plus the volume between the original ground line and the design required elevation. 1.2.2. Set up the bill of quantities items in strict accordance with the requirements of the 08 specification to avoid adverse consequences and lead to project settlement disputes. 1.2.3. ? Comprehensively and accurately describing the project characteristics of the bill of quantities is the prerequisite for ensuring the quality of the bill of quantities and the bidding control price. ?According to the spirit of the 08 specification and the provincial station guidelines, missing items or unclear descriptions of the characteristics of the list items are the responsibility of the owner. ?Be standardized, concise, accurate and comprehensive when describing the characteristics of the list items. Two basic principles should be followed: (1) The content of the project characteristics description shall be as specified in the appendix of the 08 specification. The description of the project characteristics shall be combined with the actual requirements of the proposed project, on the premise that it can meet the needs of determining the comprehensive unit price. Project Features Tips: The content of the description must be clearly described, and the text description should not be ambiguous. ? (2) If the standard atlas or construction drawings can fully meet the project characteristics description requirements, the project characteristics can be described directly by referring to the XX atlas or XX drawing number for details. For parts that cannot meet the project characteristics description requirements, text descriptions should still be used. 1.2.4. The ?08 specification stipulates that the comprehensive unit price should include the risks and expenses required by the bidders in the bidding documents. ?The determination of the comprehensive unit price is related to two factors: ?(1) The description of the project characteristics and the composition of the quota items under the list sub-item; ?(2) The price of the main materials. ? Carefully study the relevant content of the 08 specification and clearly understand how many quota items are under each list sub-item. Secondly, combined with the actual project and experience, finally determine the quota sub-items under each list for group pricing. ?It is recommended to refer to the "Guangdong Province Installation, Municipal and Landscaping Engineering Bill of Quantities Pricing Guidelines" issued by the Provincial Cost Station for project pricing. ? The current method for determining the price of main materials: Priority is given to the comprehensive price issued by the cost management department; if there is no comprehensive price, the manufacturer's price shall be considered in combination with market inquiries. ? The comprehensive price is compiled and analyzed by the cost station and is relatively close to the market, but its announcement time lags behind. For major materials such as steel, steel bars, cement, and concrete, or materials containing copper and aluminum, which are greatly affected by the futures market, in When preparing the bidding control price, if the price is compared with the comprehensive price announced in the previous quarter, and there is a large difference, the market price can be adjusted with reference to the market price. 1.2.5. When preparing the bidding control price, the cost of the measure items should be calculated completely in accordance with relevant regulations, and no items should be artificially omitted or missing. An applicable and feasible construction organization design outline should first be roughly formed under normal construction conditions. On this basis, there should be clear calculation ideas and basis for calculating the cost of measures, and the preparation instructions should be stated in detail in the bidding control price.

?Additional fee for night construction?Additional fee for traffic interference project construction?Fee for rush measures: adjusted to sub-item project fee × 0.1%?Additional fee for civilized construction sites 1.2.6. ?In the calculation of the bill of quantities, the cost of materials supplied by A should be included Comprehensive unit price and total project cost, and calculate corresponding project fees and related fees, taxes, etc. ?General explanation of the 2010 "Guangdong Province Municipal Engineering Comprehensive Quota" clarifies the calculation and rebate methods for materials supplied by A. ?When preparing the bidding control price, the materials supplied by A shall be included in the comprehensive unit price of the sub-projects according to the names, specifications and prices provided in the bidding documents. 1.2.7. ? For other projects with upper and lower cost standards in the project fee, when preparing the design budget, construction drawing budget and bidding control price, the upper limit should be calculated. ? 1. Tentative amount? 2. Tentative valuation: tentative valuation of materials, tentative valuation of professional projects? 3. Day labor? 4. General contracting service fee? 5. Material inspection and test fee? 6. Budget lump sum fee? 7. Project Quality fee 1.2.8 ? In addition to clarifying the project overview, preparation scope, and preparation basis, the preparation instructions for the bill of quantities and the bidding control price should also focus on explaining the unclear and detailed parts of the design. 2. ?2.1 Construction projects in Guangdong Province The general principles of pricing stipulate that the tenderer shall not transfer the responsibility for errors or omissions in the preparation of the bill of quantities to the bidder, and shall not require bidders in the bidding documents to consider missing items, omitted items, quantity errors, etc. other than the bill of quantities (which fall within the scope of risk) when bidding for quotations. (Except), unlimited risk, all risks or similar words shall not be used to specify the risk content. ?2.2 The 08 specification stipulates that the bidding control price should not be adjusted upward or downward. ?2.3 Among the five elements of the sub-item bill of quantities - project code, project name, project characteristics, measurement unit and engineering quantity calculation rules, the project name and project characteristics can be determined based on the actual situation of the proposed project, and the rest cannot be changed. 3. ?3.1 The filing work process of the bidding control price? Our website issued the "Guidelines on the implementation of full information filing of the bidding control price for the construction of housing construction and municipal infrastructure projects in Guangzhou" in April 2010, which provides detailed guidance on bidding control Price filing procedures. 3.2 ? 3.2.1 According to the "Construction Project Bill of Quantities Valuation Specification GB50500-2008", the bidding control price should be prepared by the tenderer with the ability to prepare, or by a project cost consultant with corresponding qualifications entrusted by it. ? 3.2.2 The tender control price announcement letter must announce the safe and civilized construction fees, off-site transportation and discharge fees of residual sludge and soil, and the provisional amount. The above fees are non-competition fees. The bidding control price announcement letter must announce the transportation distance and comprehensive unit price of the residual slag and soil transportation. The transportation distance cannot be written for comprehensive consideration. When the comprehensive unit price for the transportation of residual slag and soil of a project is different from one, the transportation distance and unit price of earthwork, stone, etc. must be indicated separately. ?3.2.3 The EXCEL file uploaded during the bidding control price information filing must be in budget format, and the comprehensive unit price analysis table is the 2010 comprehensive unit price analysis table 1 (displaying material specifications and unit prices). For a project that includes multiple professional projects, a project summary table must be provided, and the amount in the summary table must be consistent with the filing amount. ?3.2.4 The XML file uploaded during bidding control price information filing is required to be in bidding control price format (i.e. budget format, not list format). ? 3.2.5 The project overview of the preparation description must be filled in according to the actual situation. For content involving rates, construction area, quota implementation, etc., it cannot be written as None or inconsistent with the bidding documents and filing documents. ?3.2.6 When filing information for bidding control prices, upload the preparation instructions and the filing system will prompt an exception. Generally, there are two situations. First, the preparation instructions are not the standard version of the system backend. The form may have been changed during the filling process, and the rows and columns are inconsistent with the standard version. It is recommended to download a new standard version above the uploaded attachment. The download area is divided into 2003 and 2007. Format, please download the corresponding preparation instructions according to the offic software version, or refill the project information on the Guangzhou Engineering Cost Information Network/Home Page/Download Area/Appendix 5; Second, all files uploaded for filing cannot be placed in a folder, and then When compressing again, the correct operation should be to select the file and compress it directly. 4. The implementation details of the Comprehensive Evaluation of Market Conduct Integrity of Engineering Cost Consulting Enterprises stipulates: “For every serious bad behavior, 40 points will be deducted and the cost consulting business will be suspended for half a year; for every general bad behavior, 10 points will be deducted and the cost consulting business will be suspended. Three months of business operation; 5 points will be deducted for each minor bad behavior. If two minor bad behaviors occur within one year, another 5 points will be deducted and the cost consulting business will be suspended for one month. "? The comprehensive evaluation of integrity is directly related to the preparation of the cost. Relevant content: ? Serious bad behavior: “Intentionally raising or lowering the project cost or providing false reports, or colluding with a construction-related entity to harm the interests of the other party or the interests of the public.”, “In cost consultation activities Among them, those who do not implement codes of conduct or mandatory standards, or refuse to implement the mediation or explanation opinions of the Guangzhou City Cost Management Department."

? General bad behavior: "Other violations of laws, regulations, rules or normative documents of administrative supervision departments (or agencies), which have not yet reached the level of administrative penalties and criminal penalties." Notify the critic".
