Geodetic works to create horizontal and vertical geodetic very time-consuming and require not only field work, but work in the office (desk work), where a computer. Geodetic network consists of several firmly attached next to the object points, and geodetic work is to determine the exact coordinates and heights of these points from the existing State geodetic network, which covered the whole country (and sometimes you can see these signs on buildings and asphalt, in Moscow, as a rule for them is an abbreviation Mosgorgeotrest – mggt and item number). Special computer programs (eg, Credo, RGS) can call received during the geodetic measurements and to obtain accurate determination of coordinates of center network. After as the geodetic base for the construction is ready to begin surveying for the stakeout of the principal axes of the building, fence lines, sheet piling, anchoring on the ground pegs temporary roads – all these forces Geodetic Brigade. Surveyor continually monitors the development of the pit, is counting the volume of soil, which is selected from the pit, and controls the depth of development, since the construction is the rule: Better Bare did not dig, dig than (bank filling the soil is much more expensive than excavation).
When you start the stage of concrete work, surveyor working hard to stake out all the basic design of the building. This is so called marking works. Breakdown – is one of the main types of surveying in construction, without the builders would not know where to put the columns, walls, stairs, at what altitude to lift one or another construction, closures, etc. Of course, you could put the construction of “the eye” without the participation of the staff or specialized geodetic surveyor firms (eg, a Moscow company “Guild of Engineers, gofen.ru). But then it would builders are not able to observe the geometric standards SNiPs and state standards, and this, in turn, would lead to the possibility of building collapse, distortions, and aesthetic perception, when the columns were not strictly be in a row, but as trees in the forest. But take away the project nature of geodesic does not end, and vice versa – after workers installed a new design, land surveyor will check its deviations from the project and commits them to executive scheme, which then goes to the regulatory authorities (eg, inspection ).
Frequently surveying firm offering executive surveys, as a separate service. For example, it may be useful for customer if he did not hire a specialized firm to provide construction and prefer full-time surveyor firm contractor. Why? Full-time surveyor of the construction company can unsaid in its documentation very serious deviations from the project because it may cost a lot for his organization for alteration work. An independent firm will be able geodetic control of the builders most impartial manner. Well, when object is ready, you should create a topographical plan (executive master plan), which will be dealt a new object, communication, roads and entrances, etc. As you can see the construction site without the involvement of surveyors, possible and right, but the result of the workers and foremen would not order, which was calculated designers and customers work.
