Aysehatun is a multipurpose dam to be used for irrigation and energy production. ESPM has been employed by the State Hydraulic Works, and reviewed the previous preliminary studies. ESPM found out that flood calculations and HEPP capacity had to be revised, and performed new studies that are more suitable technically and economically. Cartography and geological investigations were done. Based on geological report, dam and diversion and energy tunnels, power plant, cofferdam structures locations had been determined. Final design and calculations had been prepared. Project cost calculations were made for construction tendering.

Services include:

- Final Design of Dam and Hydro Power Plant
- Construction drawings of structures.
- Updating of floods and sedimentary.
- Design of roads in project.
- Provision of data for design.
