HVAC Installation for School Expansion in Grevenbroich

This tender is for the supply and installation of HVAC systems in a school expansion project located in Grevenbroich, North Rhine-Westphalia, Germany. The project involves the installation of HVAC equipment including three compact air handling units, one larger air handling unit rated at 8,200 m³/h, approximately 650 square meters of ventilation ducts, and around 2,000 meters of spiral-seam ducting/air pipes. Additional components specified include roughly 40 backflow preventers (BSK), fittings, silencers, fans, roof penetrations, hoods, and four decentralized recirculating air coolers. The deadline for submissions is April 15, 2026.

The project's scale appears moderate, based on the ductwork quantities and the number of air handling units. The specification of a larger 8,200 m³/h air handling unit suggests servicing a significant area, potentially an assembly hall or larger classroom space. The inclusion of decentralized cooling units adds a layer of complexity. Contractors should carefully consider logistics and coordination challenges related to the various system components.

Given the lack of published contract value, a thorough analysis of the provided specifications is crucial to determine accurate pricing. Contractors should assess material costs, labour requirements (installation of various duct types and units), transportation, and any specific regulatory compliance obligations in Germany.
