Germany – Architectural, construction, engineering and inspection services – Rahmenvereinbarung Hydraulischer Abgleich, Heizlastberechnung und Einbau Thermostatregler

Fördern & Wohnen is a social enterprise of the Free and Hanseatic City of Hamburg with around 2,200 employees and over 200 locations. From emergency accommodation to assisted living: in our 6 areas of work, we support the homeless and refugees, people with mental illnesses and disabilities. For people who find it particularly difficult on the housing market, we create housing. To fulfill the legal requirements of the Building Modernisation Act (GModG) in the area of rental and property management (and in the further course also selected locations "Public Law Accommodation (ÖrU)"), the hydraulic balancing of the heating systems must be ensured. This is mandatory, in particular, when installing, modifying or optimizing heating systems and serves to check and optimize heating systems for energy efficiency in order to ensure economical and energy-efficient operation on a permanent basis. To ensure uniform, economical and immediately short-term available performance, a framework agreement with one or more suitable bidders is to be concluded. The services are to be called up as required via the framework agreement. Three lots are planned: Lot 1: Heat load calculation, Lot 2: Hydraulic balancing, Lot 3: Replacement of thermostatic valves. The framework agreement will be concluded for a period of 2 years with the option of 2 extensions of 1 further year each, for a maximum of 4 years.
