Cost analysis in the renovation of hydropower projects?

1.Wire pipes are divided into A and B grades, and now many hardware stores are selling B pipes, in the case of Liansu brand, **: A grade 6 is about 9 yuan, B grade is about yuan, and some B pipes are only and, A pipes are available.

2.The thickness of the hot water pipe and the book, ** is also more than half, with the thickness of Liansu 6 pipe more than 23 yuan, and the secondary pipe is only about 15 yuan.

3.There is only one brand of drainage pipe, and some are also divided into A and B grades, and ** is also different.

4.The power cord is also the same brand-name and general, take the Guangdong line and the general comparison, the square line is 220 yuan: 180 yuan.

The higher the number of squares, the greater the difference, which can reach the difference of 200 yuan. 5.The audio line is divided into 200C, 300C, 400C, 500C, the price is also a lot worse, 200C, some are only about 150 yuan, and 500C, to about 480 yuan.

6.The thickness of the copper core of the wire is also half of the difference. Some brands are only 50 yuan for the thick ones, and 150 yuan for the good brands. Thick ones are even more needless to say. Sina Leju 8 v9 8 | u

7.The TV line is divided into 5C and 7C equal parts of single and double network cables, the price of 5C is Yuan M, and 7C is Yuan M

8.There are also single and double network cables** ranging from yuan yuan meters.

What is the amount of water and electricity project in that suite, I will probably make a budget for a three-bedroom and two-living room of 130 square meters.

1.Power cord square = 4 turns, square = 6 turns, 4 square = 2 turns.

2.The amount of hot and cold water pipes should be 60 meters.

3.The amount of TV line, ** line, and network cable is about 60 meters each.

4.The sound depends on how much you pull, and it is generally 30 meters.

5.In terms of drainage pipes, the total price should be about 500 yuan.

6.The line pipe is about 600 meters according to the length of the line above, and the attached materials cost 300 yuan.

7.The labor cost is about 2,500 yuan.

I don't know what you mean Cost management is to control the budget, list, design changes, visas, and settlements according to the entire project The installation of the project is mainly a general contractor of water and electricity installation, power supply, water supply, intelligence, fire protection, elevators, generators, etc.

Cost accounting.

Target cost. Cost planning.

Production costs. Cost assessment.

1. Look at what facilities are required to be installed in the contract.

2. Look at the drawings and calculate the engineering quantity according to the requirements of the drawings.

3. Look at the material brand and quality requirements.

4. Look at the materials and freight.

5. Look at the amount and unit price of auxiliary materials.

6. Look at the area and structure of the house.

7. Look at the local labor**.

For example, the same chandelier, from tens of yuan to thousands of yuan, if you don't set the range before the decoration, it is impossible to do a good budget for decoration, as for how much money a square is unreliable.

Only by figuring out the above questions can we say how much it costs.

For a new house of 100 square meters, the local renovation of water and electricity will cost about 4,500 yuan for labor and materials, and 7,000-8,000 yuan for full renovation. Generally, it is 50 yuan per meter in ordinary cities, and about 100 yuan in first- and second-tier cities.

The amount of the fee depends on the following aspects:

1. If you want to realize the function, you can decide how much the water circuit is transformed.

2. Selection of water pipes and other materials.

3. The choice of the construction party, the wage of the guerrilla plumber construction is 2000-3000 yuan, and the construction fee of the decoration company is 4000-8000 yuan.

Second, how much is a square meter of hydropower transformation.

1. In general decoration companies, sometimes water and electricity are done by the same person; Some are done separately.

Plumber, to be a family, used to be all-inclusive, what to connect to the kitchen at home, what to indirectly sanitate, what to connect to the balcony, etc., a count**.

For example, 90 square meters, kitchen sink, natural gas water heater; toilet shower, toilet, washbasin, mop basin; Balcony sink, washing machine.

2. Open the line groove and connect the faucet all to get good, last year's ** was 450 yuan, and the construction period was 2-3 days.

3. Electrician, in the past, was also all-inclusive, from the beginning of the wiring slot to the end of the lamp, 90 square meters, the amount of work is relatively large, such as a lot of switches, a lot of chandeliers, etc., calculated according to 1500-2000.

Later, it was calculated according to the square, and it was calculated according to the construction area, and last year I learned that it was one square meter.

It is said that now, it is also calculated by meters, and the wires are calculated by meters, 90 square meters, you are ordinary to connect double, add some sockets, and the wires will cost 500-600 meters (all). In addition, there are weak CCTV lines.

4. Generally 90 square meters, 2 bedrooms and 2 living rooms, about 60 meters of pipes, about 600 meters of wires, 3-4 days of slotting and wiring in the early stage, and 2-3 wiring and lighting in the later stage. According to last year**, the salary of plumbers should not exceed 3,000 yuan.

Weak current installation**.

1.We know that there are many types of wires, such as ** cables, televisions, air conditioners, range hoods, etc., and the materials of these selected wires are different.

2.Line pipe: Generally, wires need to be protected with PVC pipes, and switch sockets are generally between 10 yuan and 15 yuan!

Add 16-way information integration box and add another 160 yuan set. Ensure that there are no joints in the pipe, and after the groove is buried, fill it with gypsum or cement mortar. Dark Tube**:

28 yuan m. Open tube**: 18 yuan meter.

Strong current transformation**.

Generally, the strong current switch socket bottom box 86 type 10 yuan; 118 type 15 yuan, 4 square wires plus 10 yuan per meter. The dark tube is generally 35 yuan; The open pipe is generally at 25 yuan.

Waterway renovation. Water pipe (concealed): 60 yuan meters.

Water pipe (surface-mounted): 45 yuan.

3.Sewer installation (50pvc pipe): 60 yuan.

The above ** does not include valve hardware and punching costs, and the labor costs in major cities vary greatly, and the specific ** is mainly market-based.

Home Improvement Renovation Hydropower:

1. Kitchen: the range hood socket is 2 meters from the ground, the gas water heater socket is meters, at least 3 sockets should be left on the wall of the cabinet from the ground, and the refrigerator socket, the socket of the dishwashing or disinfection cabinet should be left in the cabinet; Waterway, hot and cold water pipes at the washing tank, hot and cold water pipes of water heaters.

2. Bathroom: circuit, mirror lamp power supply, lighting lamp power supply, bath bomb power supply, exhaust fan power supply, and socket on the side wall of the washstand, which can be connected to a hair dryer or razor, washing machine socket, etc.

Waterway: hot and cold water for washbasin, cold water for toilets, cold and cold water for baths, cold water for washing machines, and an extra hot and cold water pipe for electric water heaters or solar water heaters.

In the case of construction according to specifications, the fewer design changes, the lower the cost.

Therefore, under the condition of ensuring the rationality of the switch and socket, the design of the atmosphere lamp can be reduced, and the unnecessary socket design can be reduced, which can save costs.
