The calculation formula is as follows: the unit price of unpriced main materials = the content of the quota with brackets * the main materials that are not listed in the budget price quota of main materials.
Quota is not prepared advocate material quota content = design dosage *( 1 construction loss rate) advocate material value = quota is not prepared advocate material quota content * advocate material budget price.
2, scaffolding demolition fee
Scaffold erection and dismantling costs are calculated at 5% of labor costs, of which labor wages account for 25%;
Scaffolding erection and dismantling costs = engineering labor costs * 5%; Among them, labor wage = scaffold erection and dismantling fee *25%
3. Extra-high cost increase of the project
Except for the sections where aerial work has been considered in some sub-item quotas, if the installation height of the working object is more than 5m from the ground, the labor cost of the excess part shall be multiplied by the corresponding coefficient in the table.
When the superelevation coefficient table is applied to the superelevation coefficient of engineering, the percentage of engineering labor costs that meet the conditions of superelevation coefficient in all engineering labor costs can be calculated first, then the superelevation labor costs can be calculated, and then multiplied by the corresponding superelevation coefficient, that is, the superelevation increase fee of the unit project.
4. Raise the charges for high-rise buildings
The increase fee for high-rise buildings of fire fighting and safety prevention equipment installation works shall be calculated according to the following table. The expenses are all artificial wages.
5, installation and production at the same time increase the cost.
At the same time, the increase in installation and production costs belongs to labor costs, and their calculation formula is: at the same time, the increase in installation and production costs = (labor costs in the increase in subentry coefficient of each subentry project) * 10%.
6. The construction cost increases in an environment harmful to health.
The increased construction cost in the environment harmful to health belongs to the labor cost, and their calculation formula is: the increased construction cost in the environment harmful to health = (labor cost in the increase of labor cost of various sub-projects) * 10%.
