2. The length of single root in each step is designed according to the design, and the length of anti-skid strip is not-0.15 * 2 according to the whole step width;
3. Stair antiskid strips shall be calculated according to the length specified in the design. If there is no provision in the design, it shall be calculated by subtracting 15㎝ from * *;
If you still don't understand, or can't calculate, it is recommended to find someone to help you calculate. There are companies and individuals who can help you calculate. You can also go to the platform to entrust, and the fees vary.
I. Methods
1, you can search "small ant calculation", you can do engineering quantity calculation and budget, with high quality and high efficiency.
2. You can search the budget cost units online, and some units do better.
3. You can go to a third-party platform and entrust others to do it. Pay attention to fraud prevention on the platform. You can find a unit or someone to do it.
Second, the cost budget charging standard
1, and part of the charge is 0.2-0.5% of the cost budget (assuming the project cost is 1 10,000 and the cost is 2000-5000);
2. Professional companies charge, and the factory charge calculated by Xiao Ant is about 0. 1% of the cost budget (assuming the project cost is 1 10,000, and the engineering quantity calculation cost is 1000-2000, depending on the drawings);
3. Some of them are suggested to be charged according to the cost budget quota of each province and city.
Third, the charging standard of engineering quantity calculation
1. The fees charged by general consulting companies are calculated according to the budgeted cost, because the calculation of engineering quantity is one of the most tiring and troublesome tasks in the budget.
2. Some companies charge about 0.05% of the cost budget, depending on the drawings.
Four. suggestion
1. If only the quantities are calculated, it is cost-effective to choose the quantity company.
2. If you want the cost and save money, you can now find a professional quantity company to calculate the engineering quantity, and then let people set the price, so the price is much lower (the second point mentioned above is the most cost-effective).
3. When calculating the quantities, it is necessary to see the engineering CAD drawings clearly and calculate the quantities according to the quota of the engineering position.
