Als Teil des lange geplanten Masterplans Museumsinsel Berlin wurde im Frühjahr 2022 mit den Arbeiten für das unterirdische Verbindungsbauwerk zwischen Bode- und Pergamonmuseum begonnen. Diese Verbindung ist Teil der sogenannten „Archäologischen Promenade“, welche nach Fertigstellung – bis auf die Alte Nationalgalerie – alle Museen der Museumsinsel unterirdisch miteinander verbindet. GuD wurde mit der Objekt- und Tragwerksplanung der Baugrube für das Verbindungsbauwerk beauftragt.
Die Museumsinsel blickt auf eine lange Bebauungsgeschichte zurück. Nach Trockenlegung des Sumpfgebietes diente das Umfeld der Museumsinsel als Gartenanlage, Stadtbefestigung, Exerzierplatz sowie Hafenanlagen mit Lagerhäusern. Entlang der Baugrube verlief Mitte des 19. Jahrhunderts ein Stichkanal zur Andienung der Lagerhäuser. Nach dieser Nutzung wurde 1880 mit dem Bau der Stadtbahnlinie begonnen, welche die Museumsinsel in einem Viadukt überspannt. Zu beiden Seiten wurde im Anschluss mit dem heutigen Bode- und Pergamonmuseum begonnen. Schon zur damaligen Zeit stellten die tiefen Einlagerungen von organischen Böden die Planer vor große Probleme, sodass man sich für tiefe Flachgründungen in offener Bauweise entschied.
Im Zuge der Baugrubenherstellungen wurden die historischen Bauwerksreste der letzten 150 Jahre wieder angetroffen, was die Ausführung zu einer besonderen Herausforderung machte. Die Kaimauer des Stichkanals, die Bahnpfeiler des ersten Bahnviadukts sowie eine Vielzahl von Holzspundwänden wurden wiederentdeckt. Auch die unmittelbare Nähe zu den Bahnpfeilern verlangte bei der Ausführung besondere Vorsicht, da die darüber verlaufende S-Bahn sowie Fernbahn weiterhin in Betrieb war und nur minimale Verformungen der Stützpfeiler zulässig waren. Im Schutze von eingepressten Spundwänden und einer mittelhochliegenden Dichtsohle konnte der Aushub erfolgen. Trotz der Baugrubentiefe von bis zu 7,0 m unter Geländeoberkante liegt die Baugrube vollständig in verschiedenen Lagen von historischen Auffüllungen. Dies machte die Baugrube für Archäologen besonders spannend, für die Baugrubenherstellung stellte dies jedoch eine besondere Herausforderung dar.
Im August 2023 wurde die Baugrube für die Rohbauarbeiten übergeben, sodass nun die Errichtung des Verbindungstunnels im Schutze der Baugrube erfolgen kann.
Eine junge Tradition: Der GuD-Beachvolleyball-Cup, der 2022 zum ersten Mal von GuD ausgerichtet wurde, fand auch in diesem Jahr wieder statt.
Bei hochsommerlichen Temperaturen kämpften 8 Mixed-Teams von GuD, CRP, GSE und WTM um den Sieg. Lautstarke Unterstützung aus den jeweiligen Fanblöcken sorgte für gute Stimmung am Spielfeldrand und nebenbei war Zeit für ein wenig fachliches Networking und interessante Gespräche. Die angenehme Atmosphäre in der Beachvolleyballanlage East61 in Berlin Schöneberg hat allen Beteiligten gefallen!
Wir bedanken uns bei den Kolleginnen und Kollegen von GSE Ingenieur-Gesellschaft mbH, WTM Engineers GmbH und CRP Bauingenieure GmbH für die engagierte Teilnahme und freuen uns auf den nächsten GuD-Beachvolleyball-Cup 2024!

As foundation surveyors and specialist planners for geotechnical engineering with a focus on inner-city areas, we are confronted with historical building foundations in many projects. At this year's Christian Veder Colloquium in Graz, our colleagues Josef Patron, Bert Schädlich and Fabian Remspecher presented the Pergamon Museum in Berlin as an example of the challenges that arise from the conflicting priorities of careful treatment of the historic building fabric, the high demands of contemporary building use and the imponderables of the building ground.
We would like to thank the organisers from Graz University of Technology for the opportunity to present our work, our colleagues for the exciting discussions and look forward to next year's colloquium!
The topic of sustainability in relation to energy requirements and ecological interventions is increasingly determining our work as geotechnical planners. It is therefore all the more important to define comprehensible criteria that make it possible to assess the sustainability of certain construction methods and the overall sustainability of a construction project. We are taking up this challenge and testing the practicability of various sustainability criteria in our geotechnical planning projects as part of our internal development.
At the 18th Earthworks Conference on "Sustainability in Earthworks, Foundation Engineering and Hydraulic Engineering" in Leipzig, our colleague Dipl.-Ing. Matthias Römer presented our status on the planning consideration of greenhouse gas (GHG) emissions in earthworks and road construction. Co-authors were Dr.-Ing. Fabian Kirsch and Dr.-Ing. Olaf Stahlhut.
Many thanks to the Bauakademie Sachsen for the excellent organisation and the numerous participants for the interesting lectures and discussions!
After a quick descent by lift (8m/second), we arrived at a depth of 500m. Underground, the temperatures ranged from 20 degrees to 28 degrees, depending on the depth. With open vehicles and humorous narrations by the drivers, we visited spectacular places such as the salt cave at a depth of 800 m, the concert hall with an impressive laser show, the museum and the gold room. After the three-hour tour, we drove to Fulda and ended this beautiful day with delicious pasta at the Italian restaurant "Basta e Pasta".
Who knows it? The search engine, ECOSIA, that plants trees? By using Ecosia, we at GuD support the planting of trees. Thanks to more than 6,000 search queries so far, GuD has planted a total of 123 new TREES on the planet. A small contribution to sustainability with a big effect :-)
We'll keep going!

At this year's GuD Christmas bazaar, in addition to mulled wine, delicious sausages and sweet crêpes, there were once again beautiful Christmas trees for all employees. The trees were expertly examined, measured and selected so that in the end everyone could take home a suitable tree. This is a fairly new GuD tradition, which originated during the Corona period and is now being continued!
True to the motto: "You've only really been where you've been walking". (JWvG), some GuD colleagues set off early on Saturday for a big hike, with a choice of 30 or 55 km. The 30 km group walked clockwise around the Müggelsee lake at a light pace and in good spirits. With the best hiking weather, lots of cake and good conversation along the way, the finish line was crossed after about 7 hours and the day was evaluated at sunset. For the 55 km group, the focus at this point was still on getting around. In addition to the beautiful lake and river landscape, we were also able to catch a glimpse of the new Tesla factory - through a cutting in the primeval forest of Brandenburg - as the loop led right up to the Berlin ring road. After about 48 km, the climb to the Müggelturm was on the agenda once again. After about 12.5 hours, the last riders finished and were able to put their feet up.
GuD will again be represented at this year's Baugrundtagung with an exhibition stand.
We look forward to your visit.

We are pleased that we are one step closer to our goal - the derivation of geotechnical foundation data from seismic inversion and geostatistical data integration - and that the foundations for reliability-based planning and optimisation of mono-pile foundations for offshore wind turbines are growing steadily. It remains exciting to see where the journey will take us...
How do you isolate an inner-city building from vibrations from the underground tunnel running underneath? The GuD planning team faced this complex challenge in the construction of a new commercial building in Berlin-Kreuzberg.
The new building at Ritterstraße 16-18 is supported by a steel grid so that the underground running underneath is not stressed. The bearing of the grating on the foundation elements, as well as the entire building foundation, had to be designed in such a way that the vibrations from the underground are not carried into the new building.
Based on structural dynamic FE models, GuD dimensioned the bearing on elastomer mats from Getzner. In the control measurements on the now almost completed building, the high effectiveness of the elastic building support could be proven. This means that nothing stands in the way of using the new building without disturbing influences from the underground traffic.
We are pleased to have been involved in this exciting engineering task and hope that the users will enjoy the new building!
Die Baukammer Berlin awarded a total of 15 prizes for outstanding Bachelor's and Master's theses. The group master's thesis by our employee Michelle Döbber and our former student trainee Björn Bodner on the influence of organic soil components on cement hydration in soil improvements was awarded an outstanding 2nd place.
At this year's 8th German Geotechnical Convention of URETEK Deutschland GmbH, two young civil engineers from GuD, Sigrid Wilhelm and Michelle Döbber, and a former student trainee, Björn Bodner, successfully took part in the Science Slam. The master's theses supervised by GuD were presented in an approx. 5-minute scientific lecture in combination with entertainment elements. The expert audience gained an insight into the following topics:
"Engineering statistics - How much do you trust your subsoil outcrops and transformation model?"
and
"Consolidation of organic soils - How humic substances affect cement hydration".
Many thanks to the organisers for the opportunity to be involved in the first-time implementation of a science slam in this context. We are already looking forward to the 9th German Geotechnical Convention 2023 in Hamburg!
