A detailed zero measurement is the basis for the correct start of the investment process. Using low-level laser scanning supplemented with photogrammetric data, we make documentation characterized by high detail (several hundred points per 1 m2).<\/p>\n

Laser scanning allows us to capture the terrain level even in places that are covered with forest areas, shrubbery or agricultural crops.<\/p>\n

The result is not only a precise terrain model, but also documentation that allows us to record the existing state before the beginning of the construction works.<\/p>\n[vc_empty_space height=\"44px\"][vc_gallery type=\"nivo\" interval=\"3\" images=\"10680,10681,10682\" img_size=\"full\" onclick=\"\"]<\/div><\/div><\/div>

The model performed by us is devoid of generalization, while clearly reproducing the lines of discontinuity of the terrain.<\/p>\n

A detailed and accurate inventory of the height of ground zero ensures correct (realistic) execution of the balance of earthworks and can be used at the stage of:<\/p>\n

- design - as a base numerical terrain model<\/p>\n

- cost estimation - for the purpose of offering the implementation of the investment<\/p>\n

- taking over the construction site before the start of the investment, in order to secure the investor and the contractor<\/p>\n

- comparison of the construction site with the design documentation (even before the cutting of greenery and demolition of buildings)<\/p>\n

- periodic billing of construction works<\/p>\n

We acquire and develop data for large areas in a short time. The linear nature of the railroad infrastructure makes aerial techniques ideally applicable here.<\/p>\n<\/div><\/div><\/div>
