Tacheometric survey was made from main geodetic traverse’s points, and from points of survey network. Cross-sections right-of-way and quantities DTM was extended according to Project Manager Task on bridges and floodplain sections.

In sections with satisfactory surface, survey was made more detailed with fixation all height variations. It was obligatory to show contours of asphalt coat variations.

After completing the work, second cameral control of DTM was made on weak spots of the road according to computer analysis; and by summaries of it the surface was reconstructed. Digital Terrain Model (survey) was basic information for the project design creation for highway reconstruction.
