1, where the commercial concrete is used in the project, the price difference is calculated by comparing the price of commercial concrete with the price of concrete with the corresponding strength grade in 2000, and the price difference is only taxed, and other expenses are not calculated.
2. The non-pumping price of this commodity concrete is deducted from the machine-shift fee of concrete mixer included in the original appraisal table (per cubic meter of concrete: 65,438 yuan for foundation 9 yuan, 65,438 yuan for beam, column and wallboard, other components).
3. The pumping price of this commodity concrete is deducted from the machine-shift fee of concrete mixer, dumper and hoist in the original appraisal table (per cubic meter of concrete: foundation 30 yuan, beam-column 34 yuan, wallboard 25 yuan and other components 4 1 yuan).
4. The price difference can be calculated according to the following formula: (price of ready-mixed concrete (commercial concrete)-price of concrete in appraisal table-corresponding machinery fee) ×( 1+ tax).
5, the use of pumping commercial concrete, pumping height is more than 30 meters, the pumping fee per cubic meter of concrete is 5. 17 yuan.
6. The cost of pumping agent and other additives is not included in this price, and shall be calculated separately if necessary.
7. When municipal engineering uses ready-mixed concrete (commercial concrete), it shall be implemented according to the relevant provisions in the municipal engineering valuation table, and only the price difference shall be levied.
8. The transportation fee in this commodity concrete price is calculated according to the average transportation distance of eight kilometers in the urban area. If it is more than eight kilometers, the transportation fee of 2 yuan/cubic meter will be charged for each kilometer.
Second, the calculation example:
C20 single-beam cast-in-place concrete of a project is ***80M3, and commercial concrete is adopted with the consent of the owner. Therefore:
04-025 single beam
The fixed unit price is 10034. 1 yuan /65438+300m3× 80m3 = 80272.8 yuan.
(1) Fixed direct cost =80272.8 yuan.
② Material price difference (note: material price difference is not calculated for single beam on-site mixing concrete)
③ The allowance for mobile construction is 75. 147 working days/10M3×80 M3×3.5 yuan/working days =2 104. 12 yuan.
④ Comprehensive management fee = (①+②+③) ×16.47% =13567.48 yuan (taking the four types of rates as an example).
The above total = ①+②+③+④ = 95,944.4 yuan.
When pumping commercial concrete twice, the price difference of the same strength grade is used.
(C20 pumping commercial concrete 245.4 1 yuan /M3- concrete price in the appraisal table 145. 13 yuan /M3- corresponding machinery cost 34 yuan/m3) × 80m3×1.015× (/).
∑ = one+two =101510.02 yuan.
