For Panattoni, ENACON supervised the revitalization of a large former trolleybus manufacturing site in Ostrov nad Ohří. The supervision included oversight of demolition and remediation activities, monitoring of remediated and recycled construction materials, and ensuring the contractor's compliance with environmental obligations. Following the controlled demolition of the buildings and remediation of the contaminated subsoil, the site was transformed into a modern logistics center

In cooperation with Vodní zdroje a.s., we carried out a supplementary investigation of five sectors within the former integrated steelworks site. Although the buildings had already been demolished, extensive underground structures and large volumes of surface fill remained. According to a risk analysis conducted by Vodní zdroje, the primary contaminants of concern were free-phase tar residues from former coal gas production and elevated levels of polycyclic aromatic hydrocarbons (PAHs) in the widespread fill material. Remediation was subsequently undertaken under ENACON’s supervision, including the removal of additional contaminants uncovered during earthworks for the construction of new industrial facilities.

For Panattoni and Accolade, we conducted both phases of the environmental site audit, with a particular focus on the sediment lagoons of the former sugar mill. At the time of the audit, the lagoons had already been covered with soil and backfill, including demolition debris from the former factory. A risk analysis identified elevated concentrations of polycyclic aromatic hydrocarbons (PAHs) in the fill material, classifying it as hazardous. Remediation was subsequently carried out under the supervision of ENACON specialists. Following the successful remediation, a new Amazon distribution center was constructed on the site

For the development company ICKM Real Estate s.r.o., and in collaboration with the international consulting firm ENSR, we carried out a soil and subsurface contamination survey and a risk analysis at the former Tesla plant in Vršovice, Prague. As residential housing was planned on the site, the risk assessment led to the recommendation of soil remediation.

In cooperation with the multinational consultancy firm Ramboll (formerly ENVIRON), we conducted a groundwater contamination survey at the former military barracks in Janovice. The site was intended for the construction of a plant producing automotive parts. Based on the audit and site investigation, no remediation was recommended given the intended future industrial use.

For a potential developer, an extensive contamination survey was conducted at the former steel structure plant in Ostrava–Vítkovice. The investigation covered soils, soil gas, groundwater, and construction materials. The results of the survey served as the basis for the client's economic analysis of the site's redevelopment.
