Summary

Machine-generated summary

SBH Schulbau Hamburg, the state enterprise of the Free and Hanseatic City of Hamburg, is procuring heating works at the Brehmweg 60 school. The school has 11 buildings heated by a multivalent combined heat and power system with one CHP unit (70 kW electrical, 100 kW thermal) and two cast iron sectional boilers (880 kW and 1,000 kW) fired by natural gas. One boiler is leaking and out of service, temporarily replaced by a mobile unit. The energy centre, located in the basement of building 3, will be renewed while keeping the CHP unit. The works cover widening an installation opening, a new T90 fire door, enlarging the boiler foundation, installing two cast iron boilers (about 760 kg each), buffer storage tanks, chimney refurbishment, pipework, valves, switchgear upgrades and electrical installation.
