JLU Giessen Seminar Building I

Location Rathenaustraße 21 in Giessen
The State of Hesse and Justus Liebig University Giessen intend to construct the new Seminar Building 1.

The building is planned as a free-standing four-storey multifunctional university building, which will mainly contain seminar rooms and offices. The new building is located on the Philosophikum 1 campus of Justus Liebig University Giessen in the south-east of the city, Rathenaustraße 21, 35394 Giessen.

The 4-storey seminar building contains offices, project rooms, seminar rooms, conference rooms and various utility rooms. There is an additional technical floor on the roof of the building, which is used to house the technical equipment.

The construction site equipment for the neighboring new university library building is located in the southwestern area. The building is planned as a jointless reinforced concrete structure using in-situ concrete construction.

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 organization, the conservation of resources as well as the minimization 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 recognized by the German Sustainable Building Council (DGNB).

Selected measures in the project

  • Finished parts

    The extensive use of prefabricated parts (filigree slabs, cavity walls, parapets, 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

    (Semi-)prefabricated elements (cavity walls, filigree slabs and stairs) are used in the project. In addition to shortening the construction time, this also reduces the amount of waste generated by the prefabricated construction elements.

  • Logistics and waste disposal

    In order to reduce the transportation of materials to the construction site, the aim is for delivery vehicles to have full loads. Construction residues and waste are separated on the construction site and for disposal. Due to the very high degree of prefabrication of the components and the generous construction site set-up area, it is possible to almost fully utilize the transports and reduce the number of transports to and from the construction site to a minimum.
