The core scope of work for this tender involves the "Erweiterungsbauten Gymnasium" (Gymnasium Expansion Buildings) project at Bernburger Straße in Düsseldorf. The tender specifically covers "HLS + GA" services, which stands for Heating, Ventilation, Sanitation, and Building Automation.

The project aims to transform a former comprehensive school building into a 4-stream Gymnasium to meet new requirements such as inclusion, digitalization, all-day schooling, new learning concepts, and increasing student numbers.

The Statement of Work summary includes the following core deliverables and tasks:

• Sanitary Technology: This covers rainwater and wastewater lines, including their fastenings, insulation, and fire protection. It also includes stainless steel potable water pipes, pipe fittings, sanitary objects, inlet fittings, and mounting frames. Important tasks involve testing, flushing, sampling, and ensuring a complete water exchange in the potable water installation every 72 hours to prevent stagnation between filling and handover. The building's water supply will be connected from a nearby existing building, with the tender's scope for this service limited to within the new building. Central hot water preparation is planned for the sports hall area.
• Heating Technology: This involves the delivery and installation of complete heat pump systems, including earth-laid pipes which are to be introduced into the building using annular space seals. Underfloor heating and associated heating circuit distributors are also part of this scope.
• Building Automation: This includes automation facilities, control cabinets, automation control points, cables, lines, laying systems, and data transmission networks. The contractor is responsible for the internal electrical wiring of the heat pump systems, encompassing all necessary internal connections, wiring, terminal connections, sensor and transducer lines, and control lines. Interfaces with existing electrical feeders, building automation, and other systems must be clearly defined and coordinated.
• General Construction Support: This involves core drilling and chiseling work ("Kernbohrungen, Stemmarbeiten") in various materials such as steel-reinforced concrete and masonry, across different diameters and depths. Additionally, hourly wage work ("Stundenlohnarbeiten") is to be performed as explicitly instructed by the client or site management. Site setup ("Baustelleneinrichtung") including the provision and maintenance of material containers, is also required.
