HVAC System Installation for Multiple Units in Hamburg

This tender is for the installation of HVAC systems across multiple units in Hamburg-Ohlsdorf. The project involves a variety of equipment including two rooftop air handling units (RLTs) with heating registers for external installation, one rooftop RLT unit for kitchen exhaust (also external), one ceiling-mounted RLT unit with a heating register, and a 10kW split air conditioning unit specifically for server cooling. Ductwork is a significant component, estimated at approximately 430 square meters of rectangular duct and 1,300 meters of spiral ducting, along with associated diffusers, vents, wall boxes, and slot diffusers. The inclusion of both external rooftop units and internal ceiling/split systems, along with the specialized server cooling requirement, suggests a moderate level of complexity and coordination will be necessary.

The descriptions indicate a mixed-use project, potentially involving commercial kitchen spaces and data centers or server rooms, in addition to more general HVAC needs. Contractors will need to have experience with a range of HVAC equipment types and installation techniques, as well as potentially coordinating with structural engineers for rooftop mounting of the AHUs. The size of the ductwork installation suggests a substantial installation effort is expected. Contractors must also be capable of sourcing and installing appropriate vents and diffusers for the different environments served by these HVAC systems.

The deadline is April 17, 2026, providing approximately five weeks from the publication date. Given the descriptions, potential bidders should promptly evaluate their capacity to deliver the specified equipment and services within the specified timeframe.
