    Cast-in-place concrete walls are divided into straight walls and curved walls. List entries should be prepared separately when compiling them. When compiling the list of items, each type of cast-in-place concrete wall should be listed separately according to different types, different wall thicknesses, and different concrete strength grades (including aggregate requirements).

    The different thicknesses are separated in order to facilitate the bidder to accurately carry out the wall formwork. Calculate the list quantities of cast-in-place concrete walls.

    , calculated by volume according to the size shown in the design drawing. The volume of steel bars and embedded iron parts in the component is not deducted, and the volume of the openings in doors and windows and holes outside a single area is deducted, and the wall stack is not deducted.

    and the protruding part of the wall is incorporated into the calculation of the volume of the wall.

    Cast-in-place concrete columns are divided into rectangular columns and special-shaped columns. When compiling the list items, the list items should be divided according to different sections, different column heights, and different concrete strengths (including aggregate requirements). The reason why it is necessary to separate columns of different sections and different heights is that the bidder can accurately calculate the amount of column template and obtain the column template part.

    The structural column should also be set up according to the shape of its cross-section, and the description of the characteristics should indicate that it is a structural column and the situation that formwork is required, so that the bidder can accurately carry out the concrete structural column and its formwork.

    When calculating the list quantity of a column, it is calculated by volume according to the dimensions shown in the design drawing. The volume occupied by the steel bars and embedded iron parts in the component is not deducted.

    Calculation of column height:

    1) The height of the column with beams and slabs should be calculated from the height between the upper surface of the column base (or the upper surface of the floor slab) and the upper surface of the upper floor slab.

    2) The height of the column without beams should be calculated from the height between the upper surface of the column base (or the upper surface of the floor slab) and the lower surface of the column cap.

    3) The column height of the frame column should be calculated from the upper surface of the column base to the height of the column top.

    4) The structural column is calculated according to the full height, and the embedded wall part and the volume of the human column body.

    5) Attach the corbel on the column and the column cap of the rising plate, and incorporate it into the column body volume.

    Bidders should note that the valuation quota in many areas is to deduct the plate thickness when calculating the engineering quantity of the column, and the plate thickness is not required to deduct the plate thickness when calculating the list quantity, so the valuation quantity and the list quantity in many areas are not consistent.

    When compiling the bill of quantities, the characteristics of the list should be completely and clearly described according to the content of the engineering design, in accordance with the prompts of the specification, and in combination with the rules for the use of the relevant valuation quotas.

    1) If there are various cushions under various foundations, the cushions should be included in the foundation items, and describe their plane dimensions and thicknesses or directly describe the cushion engineering quantity contained in the list items.

    2) Beams, beamless ribbon foundations and foundations of the same foundation type and different bottom elevations should be coded separately.

    3) The box Tantong type full hall foundation can be coded separately according to the foundation type, different section size, and different bottom elevation foundations.

    4) The equipment foundation should be listed separately according to the different dimensions of the block, and the project characteristics should be described in the single volume of the foundation, the size and number of bolt holes of Xiangqing equipment, the requirements of secondary grouting and its size, and the secondary grouting is not listed separately.

    The above is collected and sorted out by Zhongda Consulting.
