We perform precise measurement of the \"zero state\", which is the basis of the investment process. Using low-level laser scanning supplemented with photogrammetric data, we obtain documentation characterized by high detail (several hundred points per 1 m2).<\/p>\n

Laser scanning makes it possible to measure the ground level even in wooded and shrubby areas.<\/p>\n

The result is not only a precise terrain model, but also documentation that allows us to record the existing state before the start of the investment.<\/p>\n[vc_empty_space height=\"44px\"]<\/div><\/div><\/div>

The terrain model reflecting the zero state is devoid of generalization and its accuracy does not differ from the model obtained by classical surveying.<\/p>\n

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

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

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

- handover - 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 settlements of construction works<\/p>\n

Thanks to the use of drones, studies even for large areas are carried out in a short time.<\/p>\n<\/div><\/div><\/div><\/div><\/section>
