This topographic map created by geodetic and crew. Upon receipt of all required the developer authorizing documents and necessary projects, the geodesic team begins preparation for surveying the construction site. To do this, create a geodetic network alignment – the future basis for geodetic work. Geodesic works to create horizontal and vertical geodetic rather cumbersome and require not only the output "field", but also work in the office (desk work) for your computer. Set of points a few firmly attached next to the object points, and geodetic work is to determine the exact coordinates and altitude of the items from the existing state geodetic network, which is covered by the city. Special computer programs (for example, Credo, RGS, and others) allow you to equalize received during the surveying measurements and a positioning accuracy alignment network.
After creating geodetic framework for the construction, start by surveying stakeout major axes of the building, fence lines, sheet piling, anchoring on the ground with stakes of temporary roads – all by the geodesic Brigade. Surveyor keeps under control the development of the excavation, excavation volume counts, and controls the depth of development, so as to build a rule of thumb a little bit better not to dig, dig than (Podsypku soil is much more expensive than cutting). After the beginning stages of concrete work, surveyor working hard to stake out all the basic building structure (columns, piers, walls). This so-called stakeout work. A breakdown – this is one of the main types of geodetic works in the building, without the builders would not know where to put the columns, walls, stairs, at what height to lift a particular design, floor, etc. Of course, workers could be put concrete structures "by eye", without a staff surveyor or specialist geodesic.
But then it would not be able to comply with the builders geometric standards SNIP and GOST This, in turn, would lead to the possibility of building collapse, precipitation, and distorted. But in setting out the project in the nature of geodetic work does not end, and vice versa – after workers have established a new design surveyor will check its deviations from the project and commits them to the executive scheme, which then goes to the regulatory authorities (such as construction watchdog Inspectorate). Frequently surveying firm offering executive survey, as a separate service. For example, it can be useful for the customer, if he did not hire a specialized firm to provide construction and prefer full-time surveyor firm contractor. Why? Staff Surveyor construction company can unsaid in his executive documents and reports about a very serious deviations from the project, as this may entail large costs for the "feeding" of his organization for alteration work. Independent geodesic construction firm will be able to control most of the builders impartially and efficiently. So when the construction project is ready, you should create a topographic map (Executive master plan), which will be dealt himself a new object, its communications, roads, entrances, etc. As you can see the construction site without the involvement of specialist, high quality performing surveying work, and perhaps managed, but the result of the workers and foremen would not those on which the designers and customers are expected to construction works.
