The project, which was financed by the EU's NIF (European Union - European Commission Neighborhood Investment Facility) viaEuropean Bank of Reconstruction and Development (EBRD) for the study of the ecological status of the land which will be freed up after construction of new Tbilisi Railway Bypass.

The survey was conducted by the Danish consulting company COWI. The former use of areas within the existing railway corridor suggested that soil, groundwater, existing buildings and installations might were impacted by contaminations released during operations or due to the use of hazardous construction material. The land contamination study was carried out by COWI-with which the JSC Georgian Railway signed the contract on 7 June 2011 for identification of contaminations, assessment of risks and for planning of remediation and disposal activities required before redevelopment of the area.

The investigation provided detailed characterization of soil and groundwater contamination, an assessment of the risks to on and of site receptors, and remediation strategies for the entire area. As the results show the site is free from hazardous materials and ready for future development purposes.
