project description


The urban Fornebu is currently designed and CO2 emissions will be reduced by up to 50 percent. The main foci of the development are not only climatic and environmental aspects in the construction industry but also green mobility, urbanity, cultivation, energy efficiency, smart house technology, community solutions and sharing economies.
Together with the whole design team, Bollinger+Grohmann will be responsible for the subarea of OBOS Fornebu. The area will be a showcase for future-oriented urban development focusing on transport, energy and material use. The building is a © FutureBuilt project. The complex is approximately 37,000 m² big and the project once realised will consist of 65,000 m² residential space and up to 5,000 m² of commercial and business areas at street level. OBOS has very ambitious plans for this area.

 


The gravity structure of the four towers was constructed using cast-in-place concrete, the core walls were built in climbing method. Bubble-deck slabs (biaxial hollow deck slabs) allow for large column-free spaces. The lateral system of all four buildings is based on an innovative concept: In addition to the core walls, a friction plate between the buildings with the superimposed load of the green area on top in combination with inclined piles stabilize/brace the high-rise towers.

ERFURT - BUGA 2021

The Bundesgartenschau in Erfurt has opened end of April and the elevator with the 27m long, very light and narrow connecting walkways is in operation. The walkways connect the free-standing elevator tower with the mighty bastion wall. On the city side, the small platform at the elevator tower offers a great view towards the cathedral square and the historic centre.

SOMNIUM featured in "Stahlbau"

As part of the extension of the Johannes Kepler Universität in Linz, we were in charge of the structural engineering of the SOMNIUM, a free-form platform on the highest building on the campus. The viewing terrace, which is spatially framed by a trellis for future vegetation, serves as a remote oasis of relaxation for campus visitors.

Now the project is featured in the April issue of "Stahlbau" by Ernst und Sohn, Berlin. The authors are Thomas Schaumberger and Arne Hofmann from Bollinger+Grohmann Vienna.

Competitionline Ranking 2020

The competitionline-Ranking is the only architects' ranking in the German-speaking world that is based exclusively on competition results. Once a year, the competitionline editorial team evaluates all the competition results published on competitionline.com and creates the ranking of the most successful offices from them.

We are very pleased about the good rankings of our office in the following categories:

3rd place in the category STRUCTURAL ENGINEERS
6th place in the category CIVIL ENGINEERS
3rd place in the category BUILDING PHYSICS

April 2021

2nd place in competition: NICE HQ, Oderzo

"Nice Headquarter" is designed as a high-tech building. The key characteristics are the transparency and lightness of the façades and the roof, which is a monolithic element that opens and closes according to the sun position and weather conditions. It provides a dynamic and flexible space for the inner courtyard.

A set of integrated lights enhances the building's perception at night, maintaining a high level of visibility and a sober profile blending with the surrounding environment.

Bollinger+Grohmann was responsible for structural and façade engineering.

Stefan Polónyi (1930–2021)

We received the sad news that Stefan Polónyi has passed away on April 9.

Stefan Polónyi was a leading builder, master teacher, inventor, pioneer and role model. His exemplary contribution in science, teaching and practice strengthened the self-image of engineers and consistently enhanced constructive interaction between architects and engineers. We will miss him. Our thoughts are with his family.

Riedbergallee Student Residence: Process

The timber structure of the 5-story student residence (timber and concrete hybrid) is rising in high speed. The prefabricated CLT wall and slab elements, which span up to approx. 8 m, arrive with all necessary openings and milled slots for the service pipes and are mounted next to the buildings concrete cores and compartment walls. Together with Ferdinand Heide Architects from Frankfurt we started planning in early 2018 and were responsible for the structural engineering (LP1 to LP6) and building physics (LP1 to LP7).

AIT Award Finalist 2020

The AIT awards are one of the largest competitions for architecture and interior design in the world. The Frankfurt Pavilion by schneider+schumacher and Bollinger+Grohmann was among the finalists in the category Retail/Fair.

The iconic building was constructed for the first time at the Frankfurt Book Fair in 2018 and returned again as the venue for events with authors and industry experts from all over the world in 2019. The space-defining structure was generated and optimized by the team, taking into account architectural, structural and static criteria using genetic algorithms.

Opening Tondo in Brussels

On Thursday 14 January 2021, the footbridge Tondo officially opened in Brussels.

Designed by Office KGDVS, the "spatial element" connects the House of Representatives’ offices with its recent extensions, the new Forum Building, on the other side of the Leuvensestraat. It can be described as a stiff disc, the roof, on which the floor hangs with a minimal presence of structure.

Bollinger+Grohmann has been responsible for the structural engineering.
