土建（civil engineering） Leveling site: excavation, filling, transportation and leveling of buildings with a thickness of less than 30cm 1. Calculation rules of leveling site (1) list rules: according to the design drawing size, the first floor area of the building is calculated. (2) quota rules: according to the design drawing size, the first floor area of the building is calculated. 2. Calculation method of leveling site (1) the leveling area of the list rule: the flat area of the list rule = the floor area of the first floor (2) the leveling area of the quota rules: the level of the quota rules, the floor area = the floor area of the first floor 3, matters needing attention (1) in some areas, quota rules leveling area: the exterior line put 2 meter. Calculation, according to the outer wall outside the line of 2 meters of graphics block calculation, and then with the bottom floor area combined calculation; or according to put 2 meters outside the center line * 2= outside 2 meters area, and the bottom floor area combined calculation. In this case, the following difficulties arise in the calculation: It is troublesome to divide blocks, the arc part is not easy to handle, and the error is easy to occur. 2. The central line of 2 meters is more troublesome and difficult to calculate. After 2 meters outside, there may be overlapping parts. How many bad calculations should be deducted?. (2) in the list environment, the price of the leveling site may be calculated according to the actual situation of the bidder when the bidder quoted the price, and the length of each outside is not the same. Large excavation earthwork 1 rules for excavation earthwork calculation (1) list rule: dig the foundation earthwork according to the design drawing size and calculate the depth of excavation with the base cushion area. (2) quota rule: the volume of earthwork excavated by manual or mechanical excavation shall be calculated by the depth of the bottom of the trough multiplied by the excavat
