Description
HafenCity Hamburg GmbH is planning the realization of a zero-emission office building in wood skeleton construction at the location "Am Dalmannkai 1", centrally located in HafenCity, with a gross floor area of approximately 8,600 m2. The building is detached on 3 sides and connects in the south to the administration and workshop building of a heating plant. The zero-emissions office building shall be constructed on the basis of carbon neutrality in the overall life cycle assessment of construction, operation and dismantling. Facade and roof greening as well as a photovoltaic system on the roof and on the facade complement the zero-emission concept. The building material wood is used both constructively and creatively. The tendered service is the services of room, timber construction, facade, window and roof waterproofing for the zero-emission office building in HafenCity. The pro rata area of these services refers to a GFA of 7,811.30 m2. The construction project has already begun. The basement floor was realized as a white tub. In the ceiling level above the ground floor, a reinforced concrete girder grate is produced as a transfer level on which the timber construction is to be set up. The access cores with stairwell, elevator and main shafts are also manufactured in reinforced concrete. The contractor provides the entire load-bearing structure of the wooden skeleton structure above the ground floor ceiling as well as the dense building envelope for the facade (ground floor to attic) in timber frame construction, the roof structure, the suspended trellis, the windows as a post-and-bar construction and the substructure for the PV modules integrated and cantilevered in the facade. All interior fittings and technical supplies are assigned separately and are not part of these specifications. The greening above the waterproofing level of the planned hot roof is also advertised separately and is not to be provided by the client. The innovative overall concept serves as a national flagship project that demonstrates the feasibility of a climate-neutral office building with contemporary comfort and flexibility. For CO2 neutrality, the IFB promotion of timber construction and the certification of the HafenCity Platin Plus eco-label, product certificates must be provided with regard to zero pollution, wood from sustainable management, recyclability and CO2 emissions. The procurement procedure covers the construction of timber construction (supporting wooden skeleton construction), roof (insulation, waterproofing and green roofing / roof coverings) and facade (wood panel elements and wooden facade including windows). The tendered service is the services of load-bearing timber construction, windows, facade and roof for the zero-emissions office building in HafenCity.
