As we all know, water and electricity installation is one of the most important and complicated projects in our home decoration. If there is any mistake in water and electricity installation, it will not only bring us a lot of unnecessary trouble in future construction, but also bring us great inconvenience in future life. Therefore, it is very important to make a good budget before water and electricity installation. Let's take a look at the following: how to do the budget of hydropower project and the matters needing attention in the budget of hydropower installation.

How to do the budget of hydropower project?

1, channel reconstruction price budget:

A.20PP-R water supply pipe: 60 yuan /m b.20PP-R water supply pipe: 45 yuan /m C. Launching installation: 60 yuan /m PS:PP-R pipe is Wei Xing or Jinde pipe.

The launching pipe is a plastic pipe: 1, and each meter contains an equal-diameter reducer sleeve and a 90-degree elbow. 2, excluding valve hardware 3, 25 water pipes per meter plus 10 yuan 4 less than one meter is calculated as one meter 5, punching will be charged, bearing wall 40 yuan/a, non-bearing wall 20 yuan/a 6PP-R pipes are all hot water pipes with a skin thickness of 2.8. 7 sewer pipes shall be calculated as 50, and those greater than 50 shall be negotiated separately.

Matters needing attention in water and electricity installation budget:

First, look at the drawings carefully, and don't miss items when budgeting. This is a big problem for beginners and novices.

Second, the actual consumption of main materials and bill of quantities are two different concepts, which should be distinguished.

Third, the quota should be applied accurately and cannot be applied to other projects.

Fourth, the price of the main material should be clear.

5. Pay attention to the setting of project category, management fee and profit when using the software.
