1. Elevation of the design and implementation base (linked to the state grid), to which the x, y, and z coordinates of the completed objects will be referred to,
2. Delineation of objects,
3. Post-construction inventory,
4. Execution of geodetic as-built documentation.
5. Fieldwork
6. The contract management will involve ongoing execution of orders related to staking out railway, road, and bridge works, construction and reconstruction of underground network equipment elements and their current post-completion inventory for both monthly sales /measurements/ needs and the final post-completion report.
7. Delineation and stabilization of the main elements of objects based on the geodetic framework (design-implementation base).
8. The contractor’s independent acquisition of main route point locations, including coordinates and benchmarks.
9. Determination of working height points concerning benchmarks.
10. Measurement inventory for acceptance of works: partial, subject to concealment and final, indicating any changes concerning the project.
11. Quality control of works
12. Purchase and installation of hectometre boards
13. Due to the size of the construction, the required precision, and the fast implementation deadline, we are implementing a measurement system which is GPS/GLONASS/Galileo/Compass measurement technology for geodetic service purposes.
14. post-execution measurements should:
    • measurement of railway infrastructure elements;
    • measurement of buildings and structures;

Measurement of underground utilities carried out in the excavation before backfilling.
