2. When calculating the engineering quantity, the tamping energy and tamping times at each point according to the design requirements shall be calculated separately, and the corresponding comprehensive base price shall be adopted. At the same time, apply the same tamping energy to the mutual pressure when calculating the project (1∕2 or 1∕3).
3. The dynamic compaction amount of foundation is calculated in m2 according to the dynamic compaction area shown in the design drawing. When there is no clear stipulation in the design, the outer edge line of the building foundation extends for 5m, calculated as m2. If the space required by the design is not compacted, and the spacing is more than 8m vertically or horizontally, and the area is more than 64m2, it will be deducted, and those less than 64m2 will not be deducted.
4. After calculating the engineering quantity, it shall be priced according to the local quota of the project.
