New house hydropower transformation meter is how to calculate? This mainly depends on the owner is looking for a decoration company or construction team, generally due to the cost of the latter algorithm is more money, but the same if the choice of the latter owners need to bear the risk is relatively high, after all, do not know how the other side of the construction effect, unless it is the kind of acquaintance recommended by the construction team.
Reasons for hydropower transformation
There are two main reasons: First, the old water and electricity lines of the original house cannot meet the normal operation of the current electrical appliances, so the water and electricity transformation should be carried out from the perspective of safety. For example, many old houses use aluminum core wire and the water pipes are iron pipes, which must be replaced. Second, the individual needs for the personalized use of the new home, from the point of view of convenient use of life need to carry out hydropower transformation, such as the installation of spotlights, double control, water softening equipment. Or it is necessary to rearrange the location of water and electricity according to the configuration of household appliances, furniture and equipment.
Hydropower fixed location refers to the determination of switch sockets, water inlet and outlet, faucet locations for the purpose of hydropower renovation planning and estimation. And the more early planning has the advantage, not only let the foreman accurately estimate water and electricity, avoid the foreman to report more costs, but also make the whole decoration process more smooth. Don’t imagine how complex the transformation of water and electricity, as long as roughly determine the electrical equipment and switch socket, faucet location and number, basically foreman can estimate a quote.
Cost of strong electric transformation
1, dark wire 2.5mm2 25 yuan/m? Single tube; 4mm2:30 yuan/meter? Single tube; 45 yuan/meter for 6mm2? Single tube
2, bright line 2.5mm2 15 yuan/m; 4mm2 20 yuan/meter; 6mm2 30 yuan/meter; 40 yuan/meter for 10mm2? Single tube
In fact, including slot, wire, pipe, wages, wiring, construction, sealing slot, all wires for national standard inspection wire, installation of camera box 86×86 8 yuan/piece; 146×86 20 yuan/piece; 146×86(Ming box)10 yuan/piece; Through the wall eye: load-bearing wall 30 yuan/piece; Non-load-bearing wall 20 yuan/piece
Weak current installation materials and installation price
1, wire: telephone line, network cable, TV cable, audio cable, audio cable, video cable, background music and other use of wire.
2, line pipe: PVC rigid flame retardant electrical pipe diameter D16 line pipe.
3, weak current (telephone, television cable) separate through the tube.
4, switch socket bottom box 86 type 10 yuan/piece, 118 type 15 yuan/piece.
5. Add 16 channels of information integration box and add 160 yuan/set to ensure that there are no joints in the pipe, and fill the pipe with gypsum or cement sand slurry after cleaning and burying the pipe.
6, hidden tube price: 28 yuan/meter; Open tube price: 18 yuan/meter.
Third, waterway transformation
1, 20PP-R upper water pipe (hidden): 60 yuan/meter, 20PP-R upper water pipe (open):45 yuan/meter, water installation (50PVC pipe): 60 yuan/meter PS:PP-R pipe for Weissing or Jinde pipe, water for joint plastic pipe
2, each meter including equal diameter, reducing pipe sleeve each, 90 degrees elbow one.
3, does not include valve hardware.
4, 25 water pipe per meter plus 10 yuan, less than 1 meter according to 1 meter calculation.
5, punching additional charges, load-bearing wall 40 yuan/piece, non-load-bearing wall 20 yuan/piece.
6. PP-R pipes are all hot water pipes with skin thickness of 2.8.
7. The drain pipe shall be calculated as 50 and larger than 50 for further negotiation.
Generally in accordance with the above three aspects to do the water and electricity transformation budget, of course, different areas, different decoration companies may offer floating prices, owners or according to their own actual situation to determine the water and electricity transformation of the decoration budget. The most important thing is to find a professional regular decoration company, to avoid unnecessary increases in the later period.
