Our activity is designing in the field of TZB (technical equipment of buildings - building environment technology) and designing in the field of ZTI (equipment of medical technical installations - we process projects of domestic sewage and domestic water supply). Gas equipment projects, which our design office also proposes, can be focused both on domestic gas pipelines with appliances up to fifty kW, and also on gas boiler rooms with a total output of over 100 kW. Our design office also processes projects of engineering objects. These projects include technical infrastructure networks. These are so-called small-scale water management constructions (projects for the extension of sewage drains and water supply lines, including their sewage and water supply connections, as well as WWTP projects up to about ten EO, pre-treatment equipment - such as grease and oil separators). We are also working on projects for the extension of STL and NTL gas pipeline series and projects for on-site industrial gas pipelines.
