How to calculate the price of hydropower transformation, how to calculate the price of hydropower transformation

There are many matters needing attention in hydropower transformation, among which the price of hydropower transformation varies greatly due to the actual project size. Because there are many places to be changed in hydropower transformation, it is recommended that you make a reasonable plan and a list of hydropower transformation materials before starting construction. Here's how to calculate the price of hydropower transformation, and how to calculate the price of hydropower transformation.

Hydropower renovation price:

The cost of decoration materials accounts for the largest proportion in the decoration expenditure and is the most important factor affecting the decoration cost. There are many kinds of decoration materials in the market, with great differences in grade and quality. What grade of decoration materials to choose directly determines the level of decoration costs.

1, labor cost. The total labor cost can be obtained by multiplying the daily wage of each worker by the number of people and days.

2. Design fee. Different designers have different design complexity and different design fees.

3. Management fee. In the process of decoration, the decoration company needs to get out of the car, help people buy materials, enter the construction site to supervise the work and coordinate all aspects.

4. profit. Every decoration company is not a god, and it will definitely charge a certain profit, depending on how much it charges.

The renovation costs of regular hydropower installation companies and "street guerrillas" are also very different. Take a 100 square meter house as an example:

1. Open the wall slot for wiring. 100 square meter house needs boiling water, and the trunking is about 65-85 meters. According to the specification, the water and electricity lines must be inside the wall. At present, it is reasonable to calculate the slotting labor cost of brick wall and concrete wall in the market according to the average price 10- 15 yuan. Finishing includes filling cement, yellow sand and glue. Tools now usually include saw blades, scrapers, etc. , and 15 yuan is reasonable. Some reinforced concrete walls are extremely difficult to slot, and the saw blade and labor are very expensive, so it is necessary to increase wages.

2. Water pipes. After years of market testing, PPR water pipes are now widely used. The prices of water pipes and fittings basically account for 50% each. Some self-employed people keep the price of water pipes very low, which looks like brand-name products, but the accessories are not imported by professional suppliers of water pipes. You can calculate whether you have suffered a big loss. Manufacturers or merchants calculate labor costs according to the number of kitchens, bathrooms and balconies, ranging from 150-300 yuan/set. If you usually have one kitchen and one bathroom, you need about 60-70 meters of water pipes. Of course, the distance between the kitchen and the bathroom and whether there are drainage pipes on the balcony will affect the number of water pipes.

3. Gas pipeline. The pipeline from the gas meter to the cooker and shower is generally within12m. The safety of gas pipeline laying involves safety issues, so it is suggested that the gas company should be responsible for the layout. This part of the cost mainly includes pipes and bends, and the labor will not exceed 10 yuan/meter. The total price of this part of materials+labor will not exceed that of 300 yuan.

4. Switch socket. According to the construction quantity required by the owner, about 55-65 sets will be built in 100 square meter. This part of the labor cost is 4 yuan/set, and there are also expenses such as cassette, octagonal box and hose. Medium-quality cassette 1.7 yuan, the labor cost is not more than 1-3 yuan/set, and some electrical accessories are needed.

5, wire tube. PVC sleeves (4-branch and 6-branch) of Zhejiang Cai Zhong electric wire are usually used, and the number is related to the wiring direction and number. Strong current and weak current must be worn separately, generally within 200 meters.

6. Strong wires and weak wires. For a house with 100 square meter (building area), the normal number of high-voltage lines is within 1000 meter, including 1.5, 2.5 and 4 square millimeters, but if there are more lights, it will exceed the above number. The ratio of each specification line is about 3.5: 5.5: 1. Individuals can refer to 10m/ m2 construction area for calculation. Weak current includes TV, telephone, network cable, etc. For a house with a building area of 100 square meter, each type of wire usually needs 65-75 meters. The wiring cost of 1 yuan/meter is reasonable. At the same time, there will be a little loss of dressing and tools.

7. Make a hole in the wall. Due to the need of indoor pipe piercing, each household should make 5-20 holes in the wall. Market price 15-25 yuan/Taiwan, but some residential properties are designated as pit diggers, and the charge is 85 yuan/Taiwan. Because the number and price of holes can't be determined before the start of construction, the construction personnel can help contact the digger, which is more affordable.

In addition, it should be noted that this price is for reference only! Of course, due to different regions, the price will be different. The above detailed introduction is only the most basic budget, and the final cost of hydropower transformation depends on their actual situation.
