Feasibility study, analysis of solutions, preliminary design, tender design and tender documents.
Layout study. Review and study of the national geotechnical and seismic regulations affecting foundations. Geological-geotechnical study of each of the areas in which the different infrastructure planned is to be implemented, with geotechnical and stability calculations for the storage reservoirs, as well as a geological-geotechnical visit along more than 2,000 km of the water pipeline route, desalination plant and the most important civil work areas.
Preliminary environmental impact study and definition of mitigation measures; study of the impact of brine emissions on the Caspian Sea, simulating the effluent plume and brine behaviour in the surrounding area, and treatment alternatives study.
Socio-economic study (CAPEX and OPEX), evaluation and financial project structuring.
