Electrical works for the Grubenstraße functional building

Summary

The contract covers electrical and low-voltage works for a new functional building at the sports facility at Grubenstraße 65 in Erfurt. The contractor must supply, install, connect and commission the building’s electrical systems, including the metering and main switchboards, distribution boards, cable routes, power cabling and data cabling. The works include general and emergency lighting, earthing and equipotential bonding, a data network, an audio door-entry system with an IP gateway, a call system for the accessible toilet, and KNX building automation for underfloor heating and three ventilation units. The rooftop photovoltaic system requires a suitable connection and control to direct surplus electricity to the heat-storage system.

Bidders should account for any valid concession required for the electrical work, a qualified electrical works site supervisor and trained installation staff, and compliance with applicable DIN/VDE and fire-safety requirements.
