Building Engineering Systems: Design, Installation, Modernization and Maintenance

Feniks specializes in comprehensive technical inspection, design, installation, modernization, and maintenance of building engineering systems. We carry out the full scope of work on heating systems, water supply, sewerage, and heat substations, and also perform technical inspections of building electrical systems. Our work is guided by current construction codes, technical regulations, and industry standards, ensuring the reliable, safe, and energy-efficient operation of engineering infrastructure throughout the entire lifecycle of a facility.

Our approach is built on engineering methodology: every project begins with a technical inspection and analysis of existing infrastructure, includes the development of design solutions that account for operational loads, and concludes with system commissioning followed by ongoing service support.
