Is there a contractor for surveying and pay off in the building? What are the benefits of doing so?

Some. This can save a lot of trouble, modern society is about teamwork, and it is impossible to earn all the money alone.

Pay-off pulley: divided into ground cable pulley, cable pulley, sky pulley, nylon pulley, cable wire pay-off pulley, large-diameter pay-off pulley, dual-purpose pay-off pulley, ground pay-off pulley, lifting pulley. It is mainly used to play a protective role when laying cable wires, saving time and effort, and the use of ground cable pulleys

It is used when the cable is extended to change direction to protect the cable from friction.

Yes, there are good people or companies that specialize in surveying or technology. For the boss, although it increases some costs, it also saves a lot of worry. In the current construction market can still be promoted, because the competition is fierce, the boss does not know when there is a job, all the jobs are not easy to recruit, all are willing to use this method.

If you contract out, the boss will not take the risk. Some bosses he doesn't trust surveyors. If there is a problem with the pay-off, the newly recruited will cause rework.

The little things are fine. The big one can let the boss go home (we have it here. Overall ok.

It is necessary to aim at tunnels, bridges, roadbeds, etc. There is nothing technical about housing construction surveying.

Nowadays, more and more bosses are taking measurements out, because it is much easier. If you ask for a surveyor's salary and overtime, you will be troubled. But after the contract goes out, what problems will be filled, no matter what time it is in the morning, or what time it is noon, you have to go when it is time to release the line.

There is no reason for it.

Yes, there are people who specialize in this business.

Summary. Hello, I am glad to answer for you, the pricing method of measurement pay-off contracting is determined according to the contract and the actual situation of the project, and it can generally be priced in the following ways: 1

Meter-based pricing: that is, the price is calculated according to the length of the line measured and pay-off, which is generally applicable to shorter lines, such as indoor walls, floors, etc. 2.

Valuation by area: that is, it is priced according to the area of the measured pay-off, which is generally applicable to outdoor sites, buildings, etc. 3.

Valuation according to engineering quantity: that is, it is priced according to the workload of measurement and pay-off, which is generally suitable for large-scale projects, such as roads, bridges, etc. Different valuation methods have a certain impact on the workload and difficulty of the contractor, so it is necessary to negotiate and determine the pricing method according to the actual situation when signing the contract, and clearly stipulate it in the contract.

How are tunnel surveys priced?

The valuation of tunnel surveys is usually determined based on a variety of factors such as the complexity of the project, the amount of work, the technical requirements, the number of personnel, and so on. Generally speaking, the pricing of tunnel surveys can be considered according to the following aspects:1

The scale and difficulty of the measurement project: The larger the scale and difficulty of the measurement project, the higher the cost of manpower, material resources and time required, and the higher the valuation. 2.

The use of measuring equipment: The use of measuring equipment is one of the important factors affecting the pricing of rubber equipment, and the cost of using different measuring equipment is different, which will also affect the accuracy and efficiency of measurement. 3.

Number and skill level of staff: Surveying requires a certain level of skill and experience, as well as a sufficient amount of manpower. The difference in the number of personnel and skill level will also directly affect the cost of measurement.

4.Preparation of survey report: After the completion of the tunnel survey, the survey report also needs to be prepared, and the complexity and requirements of the report preparation are different, and the time and labor costs required are also different, which will also have an impact on the pricing.

In conclusion, there are many factors that need to be considered in the pricing of tunnel surveys, and the pricing of different projects will vary depending on various factors.

To put it simply, it is to move the things on the drawings to the ground, and remotely control its position and size during the construction process, then it is necessary to pay off the line, which is called construction measurement and pay-off.

There are two aspects to building surveying and pay-off.

One is the plane pay-off, the main content is to determine the position of the plane position of the building structure on the ground according to the requirements of the design drawings, including the general plane position and the axis of each unit project. The most commonly used tools are total stations, levels, and rulers.

The other is the pay-off of the façade, the main content of which is the vertical control of the new building structure and the control of the floor height according to the requirements of the design physique. The most commonly used tools are theodolite, vertical collimator, thread hanger, and long ruler.

In addition, there is also a very important job of building construction surveying, which is the settlement observation of building structures.

Two or three people are fine. I also graduated from school not long ago, and now I am the supervisor of a project, from my experience, whether it is when I am an assistant constructor or in the current work, there must be a transition stage, especially from the transition stage from students to social work, that is, the qualitative stage in the future work, so I suggest that you find a better master, go to the site to experience, not afraid of hardship, learn more things, such as measurement, pay-off, calibration and a series of things will be a matter of course.

Look at what is measured, basically the instruments used in positioning measurement are theodolite and total station, height difference measurement is mainly used in the level, the specific is not a moment can be clear, it is best to go to the construction bookstore to buy a book on measurement to read it, and then practice on the construction site, you can, not a very difficult thing.

Three people, two people remove the tape measure, and one person plays the white lime line.

1。Proficient in the operation of various instruments.

2。Measurement plans can be prepared for special-shaped buildings, and on-site measurements can be made.

3。For the accuracy of construction, such as the offset of the axis, the horizontal error can be controlled within a certain small range.

4。The speed of pay-off must be fast.

High-rise + the following use of the outer space method, that is, to lay a good control pile, with a theodolite to measure the axis. + The above adopts the internal control method, that is, the control axis is projected to the first layer plane with a theodolite, and the steel plate is embedded in the visible position of the first layer plane, and the intersection point and scoring are found on the steel plate with a theodolite, which is used as the base point of the vertical projection axis, and then the plumb meter can be used to measure the axis n layer upwards at this point.

It is advisable to buy a book or ask someone with experience.
