Based on many years of experience in immission control law, we advise you as an operator of plants requiring authorisation in accordance with the Federal Immission Control Act (BImSchG) on the realisation of planned site, plant and operational expansions. We check the permissibility of your projects in accordance with planning and immission control law at an early stage, develop individual strategies and provide you with customised advice from planning and approval through to implementation across all HOAI service phases. 

For companies and businesses with existing planning concepts, we offer a full management solution for the completion of extensive authorisation procedures in accordance with the BImSchG. This includes the preparation of complex approval documents, immission forecasts and expert reports as well as coordination and accompanying consultation with approval and specialist authorities.
