Construction work for the Center for Deep-Sea Research (ZfT) began in February 2021. The ZfT will investigate fundamental processes in the deep sea. Organizationally, the ZfT will be located under the umbrella of the Research Faculty MARUM. The building is scheduled for completion in mid-2024.
More information on the ZfT can be found in the MARUM press release from 29.06.2018 "New research building for marine research in Bremen" and on the website of the University of Bremen about current construction projects.
Our colleague Volker Diekamp continuously documents the construction progress with his camera.
The construction progress
From the middle of October, the excavation work, i.e. the preparations, took place so that the actual construction of the research center could start.
For this purpose, the construction site is being cleared and the ground is being prepared for the weight of the new building. Of course, archaeologists, bird protection experts and the explosive ordnance disposal service have examined everything in detail. In addition, the building ground was examined and a tree cadastre was created.
Before the soil is compacted in some places using a so-called vibration process, it has to be pulled level. During the vibration process, the soil is " shaken in" and sand that sags afterward is filled in. This increases the load-bearing capacity of the subsoil.
The excavation work has been successfully completed, now it's time for the structural work. In the coming steps, the foundation will be laid.
This includes that the sewage, fresh water and empty pipes are laid, the main sewer connection is set up and everything is sealed, the floor slab (base plate) is poured. The laying of the supply lines also includes, of course, that the power connection is set up.
In the area of the future elevator shaft, excavation work is being carried out somewhat deeper so that the so-called elevator underpass can be formed. This will also be the foundation for the 2nd construction crane.
As soon as all this has been done, work will begin on the outer walls. To ensure that the building can settle optimally, this will first be done in the direction of the waterway.
Of course, the shell of a building does not only include the exterior walls. Interior walls, intermediate ceilings, and additional floors and stairs also fall into this phase. From the foundation to the roof truss, the building slowly takes shape.
The walls of the first floor, the next floors and the new core repository have been built. Now the "tower" with the future offices is being built along the Fleet/ Hochschulring. A new vantage point on the construction site provides a better view.
An important milestone: The topping-out ceremony was celebrated on November 14, 2022.
Around a year after the start of construction work, the topping-out ceremony has now been celebrated at the Center for Deep-Sea Research (ZfT).
More about the topping-out ceremony can be found here.
The building construction is almost finished, now the technical interior work and the completion of the facade begin.
At the beginning of April, the connection between the MARUM main building and the new building of the Center for Deep-Sea Research was also created architecturally. A bridge between the two buildings was installed on the second floor.
For this purpose, the facade first had to be opened, metal elements were chiseled out and masonry transoms were removed.
The new connecting bridge was then installed within one day. In the coming weeks, it will still be glazed.

Meanwhile, the dry construction of the ZfT continues.
The facade is also continuing to take shape: The first facade sheets are already hanging and can be seen through the scaffolding.
The Corten steel used here is characterized by its rusty surface, which is not only aesthetically pleasing but also protects against further corrosion. The orange-brown steel gets its versatile hues from a layer of oxidation. This patina of metal oxide protects the steel from weathering.
The designation "COR-TEN" is derived from English and stands for "Corrosion Resistance" and "Tensile Strength", which underlines its resistant properties.
