1) List items shall be divided in strict accordance with the relevant appendices of Code for Valuation with Bill of Quantities of Construction Projects, and the list coding shall be standardized.
2) When the same kind of components have an impact on the comprehensive unit price or related measures due to different characteristics, the list items shall be set separately, the characteristics shall be described separately, and the last three digits of the list code shall be used to distinguish them. For example, there are 400*400 and 500*500 concrete columns on a certain floor of a building, and a separate list is needed to facilitate the bidder to calculate the template cost of these two columns. For example, in a building, the concrete strength design grades of concrete columns with 400*400 cross-section are C25 and C30 in different parts, and the list items should be listed separately, so that bidders cannot quote the concrete columns with strength grades respectively.
3) The description of the characteristics of each listed item should be as detailed as possible, so that the bidder can accurately calculate the comprehensive unit price.
4) The terminology of feature description should be standardized. The measurement of engineering quantity should also be as accurate as possible.
In the extended data 1 and the comprehensive unit price analysis table of the bill of quantities, the quantity in the material cost details is the total quantity calculated according to the drawings.
2. Comprehensive unit price analysis is the process of analyzing the labor, materials, machinery, enterprise management fees, profits and expenses included in the detailed unit price according to the quota, and the result is the comprehensive unit price analysis table.
3. Comprehensive unit price: refers to the labor cost, materials and engineering equipment cost, construction machinery use fee, enterprise management fee, profit and risk cost within a certain range required to complete a specified list item.
Note: In engineering projects, the comprehensive unit price method derived from the comprehensive unit price is often used to calculate the engineering cost.
