EL-TO CHP ZAGREB

Zagreb, Croatia

On the construction project of the high-efficiency combined heat and power plant CHP EL-TO Zagreb, geodetic works were carried out in the role of main geodetic contractor.

Project Description:

The new CHP EL-TO Zagreb combined heat and power unit, with an electrical capacity of 150 MW and thermal capacity of 114 MW, represents a key investment for the reliable supply of electricity and heat to the city of Zagreb. The project contributes to increased energy efficiency and supply security.

Geodetic Works Performed:

• Gas Turbine:
  Control of allowable deviations during the installation of structural elements using 3D laser scanning. Millimeter-accurate results were used for further mechanical alignment.

• Steam Turbine:
  Verification of allowable deviations during turbine installation using closed-loop leveling methods. Measurement quality was controlled by Doosan Škoda Power.

• Heat Exchangers:
  Inspection of deviations between the as-built state of the heat exchanger flange and the designed specifications.

• Metal Profiles:
  3D modeling of part of the facility’s structure to analyze misalignments of guide rails and produce matching steel profiles.

• Access Roads:
  Topographic survey of the existing terrain, staking out and as-built documentation, volume calculations of used materials, and obtaining necessary permits for project completion.

Project Significance:

The construction of this high-efficiency unit ensures a stable and sustainable energy supply for Zagreb, with improved efficiency and reliability. Geodetic works contributed to the precise execution of key infrastructure components, ensuring long-term quality and durability of the facility.
