Among the main underground infrastructure projects with which Geokos A&A has been involved is the project "Water supply and wastewater disposal in Prishtina", at the request of the client JV DORSCH International consultant.

For these projects, geotechnical drilling up to a depth of 20m, SPT field tests, water permeability tests, and soil identification tests were performed.

In 2021, by order of the Municipality of Prishtina, Geokos A&A has conducted geotechnical investigation of Road A, which will connect southern and eastern Prishtina. This road is expected to have a great impact on the discharge of traffic in the capital.
