The original pricing method is to calculate the direct cost and material adjustment cost of each subproject according to the budget quota, and calculate the comprehensive indirect cost, fees, other expenses and taxes on the basis of fixed direct cost or labor cost to form the total cost of the project. According to the principle of "separation of quantity and price", the valuation of bill of quantities separates the substantial consumption of the project from the consumption of construction measures, and consists of partial project fees, measures project fees, other project fees, fees and taxes. 2, the characteristics of the bill of quantities valuation specification? (1) Mandatory: The clauses marked in bold in this specification are mandatory and must be strictly implemented. According to the provisions of the valuation standard, all large and medium-sized construction projects invested by state-owned funds or state-owned funds must adopt the bill of quantities valuation method; Other construction projects that must be subject to tender according to law shall be priced by bill of quantities. (2) Unification: four unifications, that is, unifying project codes, unifying project names, unifying units of measurement, and unifying engineering quantity calculation rules. (3) Competitiveness: The consumption and unit price of labor, materials and machinery in the bill of quantities shall be quoted by the enterprise according to the enterprise quota and market price information, and with reference to the social average consumption quota issued by the competent construction department. (4) Practicality: In the valuation specification, the project name is clear and clear, the calculation rules of engineering quantity are concise and clear, and the characteristics and contents of the project are listed, which is convenient for determining the project cost. (5) Universality: in line with international practice, in line with the requirements of standardization of engineering quantity calculation methods, unification of engineering quantity calculation rules and marketization of project cost determination. 3, the guiding ideology of the bill of quantities valuation specification? (1) Government macro-control, independent quotation by enterprises, and price formation through market competition. (2) The principle of organic combination and difference with the current budget quota. (3) Considering the current situation of project cost management in China, the principle of integrating with international practices as far as possible. 4. What is the basis and principle for compiling the bill of quantities valuation specification? The valuation standard of bill of quantities is formulated according to the Bidding Law of People's Republic of China (PRC) and the Management Measures for Contracting and Contracting of Construction Projects (OrderNo. 1 1). The Ministry of Construction 107) forms the price according to the needs of China's project cost management reform and the principles of national macro-control and market competition. 5. What is the difference between the project settlement method after the implementation of the bill of quantities and the original quota method? The difference between the engineering settlement method based on bill of quantities and the engineering settlement method based on quota pricing is that the comprehensive unit price is generally unchanged, there is no price difference, and there is no need to adjust various rates. 6. What are the requirements for the preparation of the pre-tender estimate after the implementation of the bill of quantities? The Law on Tendering and Bidding stipulates that if there is a pre-tender price for a project subject to tender, the pre-tender price shall be referred to when evaluating bids. The reference function of the pre-tender estimate determines that the preparation of the pre-tender estimate should be mandatory, which is mainly reflected in the following aspects: the preparation of the pre-tender estimate should be based on the consideration of a reasonable construction scheme, priced according to the provisions of the pricing specification, pricing table and cost quota, and the material price should be determined according to the market guidance price issued by the municipal cost management department. 7, using the bill of quantities to prepare the pre-tender estimate, we must first determine the construction plan according to the steps, how to prepare a reasonable construction plan for the tenderer or intermediary consulting institutions, and what is the basis? Pre-tender estimate refers to an expected price compiled by the tenderer or the entrusted engineering cost consulting unit on the basis of the bill of quantities, which is the tenderer's expectation of the construction project budget. The pre-tender estimate is not the standard price that determines whether the bid can be won, but the reference price when evaluating and comparing the bids. Therefore, when preparing the pre-tender estimate, the tenderee or intermediary consulting agency must consider the mandatory standards and specifications related to the quality, safety and environmental protection of the project cost according to the specific conditions of the project, and prepare it according to the normal and reasonable construction methods and schemes.
