ZAL 2

Hein-Saß-Weg 22 site in Hamburg
The Center for Applied Aviation Research, which was completed in 2015, is being expanded to the maximum extent permitted by building law .

In addition to a conference and meeting area on the ground floor, this extension will mainly house the German Aerospace Center.

The existing ZAL consists of a central building and two wing buildings. The building ensemble is located perpendicular to the Steendiek Canal on the Elbe. The central building is mainly used for access and communal facilities (conference, innovation marketplace, meeting room, canteen), while the wing buildings directly connected to the left and right house the laboratory and hall areas. The halls are enclosed on the outside by the associated laboratories and offices. The left wing building, known as Building A, is now to be extended to the building boundary parallel to Hein-Saß-Weg.

Like the existing Building A, the new building consists of a 5-storey frame structure and an equally high, single-storey hall, which are arranged at right angles to Hein-Saß-Weg and the Steendiekkanal as an extension of the existing building.

The extension has a floor area of approx. 60 x 40 m. The height is approx. 21 m. The height is approx. 21 m. This corresponds to a GFA of approx. 8,342 m² and a BRI of approx. 60,687 m³.

The project is aiming for DGNB "Sustainable Building Site" certification from the German Sustainable Building Council.

Certified by the German Sustainable Building Council (DGNB)

Ed. Züblin AG is pursuing several goals with this project: A sustainable construction site organisation, the conservation of resources as well as the minimisation of emissions, responsibility for the health and well-being of the builders, the cultivation of good neighbourliness and, of course, high-quality construction. For this, Ed. Züblin AG was the first company to be recognised by the German Sustainable Building Council (DGNB).

Selected measures in the project

  • Finished parts

    The extensive use of prefabricated parts (filigree slabs, columns, beams and stairs) means that a shorter construction time can be achieved. The volume of waste is also reduced thanks to the prefabricated orders.

  • Digital concrete call-off

    In order to be able to coordinate the concreting in the best possible way, the call-offs are made using a digital application. The delivery rates can be coordinated with the concrete pump, particularly for large-scale concreting, thus reducing the waiting times of the concrete mixers. Production times are optimized and noise emissions are reduced.

  • Saving resources and reducing emissions through LEAN Construction

    As part of the lean approach, a production plan with call-off dates (e.g. insulation) was created. Construction production planning is detailed on a weekly basis and adapted to actual production progress. Changes in the construction process are constantly taken into account and just-in-time deliveries can be better implemented. Repeat orders and new orders due to late changes to the plan are avoided.

  • Energy management in construction

    Construction site investigations and comparative considerations for the most energy-efficient project execution possible. For example, selection of a large concrete bucket to reduce the number of lifts.
