How to calculate the water and electricity materials for the installation of iron pipes in office bu

Basically, there is no big standard, right, mainly based on experience, depending on how long the construction period is?

Let's make a rough judgment.

It depends on the specific project of the project.

It is then calculated according to the design of the floor.

The general measurement method of hydropower engineering is to do the appropriate amount, so that it is beneficial to both the decoration company and the owner, and when making a budget, it is only necessary for the decoration company to be able to provide the unit price of the service items involved carefully and in detail. In the early stage of construction, the owner will combine his actual needs, according to the location of sockets, switches and faucets and the corresponding quantity requirements, the decoration company will adjust and lofting the construction according to the appropriate amount of standards. At this time, it is necessary for the decoration company to use a marker pen at the construction site to initially set out the specific construction amount of hydropower renovation before doing it.

And determine the number of meters, combined with the previous unit price, after obtaining the total price, taking into account the changes during construction, it is also necessary to constrain the total price up and down percentage, so as to make an accurate hydropower budget.

According to the local quota market ** labor to determine, if the labor is 64, the labor cost is 35 45 yuan per square meter, the material cost is 30 40 yuan per square meter, if the approved labor unit price is 62, that is, 62 divided by 64 times 35 40 and 62 divided by 64 times 30 40.

There is no quick way to calculate the decoration of water and electricity materials, everything depends on experience.

According to the layout of the room and the layout of the line to calculate the material, first use a ruler to measure the length of the pipe, and then calculate the use of several elbows, tees, inner and outer wire joints, this is not a quick way, is adapted to local conditions.

If you do it often, you can basically estimate it. There is a stupid way, but also experience, the amount of water pipes for home improvement is generally between 20 and 30, take 30 is it, elbow press 50, directly press 20, inner wire 15, valve 8, faucet 6. It's enough to refund more and make up less.

Interior decoration materials are divided into main materials and auxiliary materials, the main materials include: floor tiles, floors, wall tiles, baseboards, hardware accessories, bathrooms (toilets, basins, partitions, shower showers, bathtubs, floor drains, triangular valves, mirrors, floor tiles, wall tiles) kitchen (wall cabinets, floor cabinets, floor drains, triangular valves, stoves, range hoods, floor tiles, wall tiles) wardrobes, sliding doors, bedrooms, kitchens, bathroom doors, etc.

Auxiliary materials include: cement, yellow sand, red bricks, water pipes, wires, network cables, switch panels, gypsum boards, woodworking boards, plug-in boards, nine-centimeter boards, plywood and other boards, latex paint, caulk, tape, small hardware (nails, screws, etc.) and so on.

According to the layout of the room and the layout of the line to calculate the material, first use a ruler to measure the length of the pipe, and then calculate the use of several elbows, tees, inner and outer wire joints, this is not a quick way, is adapted to local conditions. If you do it regularly, you can basically estimate it. There is a stupid way, but also experience, the amount of water pipes for home improvement is generally between 20 and 30, you take 30 on it, elbow press 50, directly press 20, 15 inner wires, 8 valves, 6 faucets.

It's enough to refund more and make up less.

Waterways, you generally just have to roughly estimate the value.

circuit, you see, when they are installed, the same wire to the place, is there a few sockets.

If this situation is less, you will be counted as 80 yuan per person. It's 7-8 meters.

If there are many such cases, you can calculate it at 50 yuan per person.

No, I include a row of downlights in the ceiling.

Rice copper wire, * 3+2 yuan wire pipe money, so it is easy to figure it out.

Buckles, pipe fittings and other small pieces can be counted together for 100-200.

Water utensils: bathtub, washbasin, sink, urinal, toilet, valve, faucet, accessories bathtub trap dg50. Galvanized steel pipes DG15, DG20, DG25.

Galvanized elbows DG15, DG20, DG25. Rubber sheet. Water pipe sealing tape.

Oil. Galvanized pipe hoop DG15. Wood screw L32 50mm.

Toilet trap dg100. Galvanized union DG15, DG25. Pipe clips.

Toilet rubber bowl. Threaded shut-off valve (J11T-16DG15). Water tank inlet nozzle DG15.

Cast iron sewer pipe DG50. Water trap (pig iron) S-type DG50.

2) Water supply and drainage pipes.

1. Main materials: water supply pipes, water valves, various elbows, drainage cast iron pipes, floor drains. Loss of 5%.

2. Installation materials.

Hydropower installation is not based on the area of the house, but according to the amount of work that needs to be installed. Including line length, wire diameter, pipe diameter, required switch panel and its brand, faucet valve, etc., these situations will need to be communicated first, and then the construction drawings will be issued, and finally there will be a budget; Preliminary communication, such as asking the construction party to **, it is only a basic estimate, which can only be used as a reference.

Then it's pretty simple for you, all go to the top.

Walking water and electricity are generally done by electricians, and they are also the most important things to consider before renovation. So in general, whether the decoration is good or not, water and electricity account for most of it.

If you are a contractor, please refer to the market material to make a purchase table. Then calculate the total cost and divide it equally. You know how many parties there are!

If it is a contractor, it will be based on the employment of the local market**. Then add the overtime pay for staying up late at night. Accounting based on the number of days completed!

Hello, happy to answer your questions.

Chengdu home improvement hydropower renovation is calculated according to the number of meters, the situation of contracting labor and materials is changed to 28-40 meters, and 35-80 meters of water, ranging from height to level. According to the different design schemes and personal living habits to transform the hydropower, the amount of work is also different, and the total cost is also different. However, what can be determined before construction is the unit price.

** It is a factor to consider on the one hand of hydropower transformation, and the construction process and material quality also need to be paid attention to. A good hydropower renovation company has unified and standardized process requirements, and at the same time, the company's professional construction team can ensure the specifications and standards of the site.
