How to calculate the water and electricity installation

Generally, there are two kinds of cost for water and electricity installation calculation: 1, calculated by area. 2, according to the quota valuation.

The following is calculated according to the quota valuation:

The water and electricity installation price is divided into three parts: 1. High-voltage installation part. 2. Weak current installation part. 3. Waterway reconstruction.

A, weak current installation materials and installation price.

1. Wire: used for telephone line, network cable, TV cable, audio cable, audio cable, video cable and background music.

2. Conduit: PVC hard flame-retardant electrical conduit diameter D 16 Conduit 3 weak current (telephone and TV network cable) passes through the conduit separately. Switch socket bottom box 86 is 10 yuan/piece; 1 18 type 15 yuan/piece. Add 16 information integration box and 160 yuan/set. Ensure that there is no joint in the pipe, and fill it with gypsum or cement mortar after burying the pipe. Concealed pipe price: 28 yuan/meter. Ming Guan price: 18 yuan/meter.

Material: 1PVC conduit thickened cold-bent pipe wire.

Second, high-pressure installation materials and prices.

The threading in the flame-retardant electrical pipe shall not exceed 3 buttons, and 5 yuan shall be added for every meter exceeding 3 buttons. There is no connector for the wires in the pipe, and the junction box is used. Type 86 switch socket box 10 yuan/piece; 1 18 type 15 yuan/piece, 4 m2 conductor per meter plus 10 yuan. Multiple pipes in the same tank are charged according to multiple hidden lines. Remove the groove, bury the pipe, and fill it with gypsum or cement mortar.

Covered pipe: 35 yuan/meter.

Ming Guan: 25 yuan/meter.

Material: PVC wire thickened cold bending pipe, electric wire.

Third, high-voltage installation materials and prices.

The threading in the flame-retardant electrical pipe shall not exceed 3 buttons, and 5 yuan shall be added for every meter exceeding 3 buttons. There is no connector for the wires in the pipe, and the junction box is used. Type 86 switch socket box 10 yuan/piece; 1 18 type 15 yuan/piece, 4 m2 conductor per meter plus 10 yuan. Multiple pipes in the same tank are charged according to multiple hidden lines. Remove the groove, bury the pipe, and fill it with gypsum or cement mortar.

Covered pipe: 35 yuan/meter.

Ming Guan: 25 yuan/meter.

Material: PVC wire thickened cold bending pipe, electric wire.
