Cooling System Replacement

Summary

The tender concerns design and engineering services for renewing cooling generation and cooling transfer systems in a technical building in the Roth district, including cooling for a server room. The work covers planning the replacement of chilled-water units and heat rejection units, installing two server-room air-conditioning cabinets, modifying an electrical connection between two separate low-voltage main distribution systems, and updating existing and as-built drawings.

The bidder must meet enhanced security requirements and provide evidence of turnover, insurance, professional qualification and security-cleared personnel. The construction-phase methodology carries the highest evaluation weight at 40%. The tender deadline is 12 October 2026.
