# Heating, ventilation and sanitary renewal at Netzwarte Heslach

Stuttgarter Straßenbahnen AG is procuring building works to renew heating, ventilation and sanitary systems at Netzwarte Heslach in Stuttgart. The single-lot scope includes fire-safety improvements to the signal-box building, modernization of heating, ventilation and cooling systems, replacement of the existing heat pump, adjustment of air distribution and sanitary fire-stopping. Heating pipes and radiators are expressly excluded from renewal; cooling for two rooms will use separate recirculating units. The work period is 11 January to 15 September 2027. Award is based on price alone.
