Project information

Property type: School
Component: Facade
Motivation: Renovation
Service: Load Test

washed-out concrete facade

The facades of the reinforced frame construction should be energy-efficiently refurbished. The joints showed partially defects, so that the load transfer of both vertical and horizontal wind loads could not be shown satisfactorily.

Precast light-weight concrete slabs

The roof of the "Neuen Museum Weserburg" in Bremen, Germany, is made of light-weight concrete slabs. They showed visible deformations and cracks (w ≤ 0,5 mm). We tested both its seriveability and its load carrying safety.

Emergency safeguarding, flak bunker, Hamburg, Germany

Property type: Bunker
Component: Ceiling + joist
Motivation: Conversion
Service: Diagnosis + hybrid statics

Emergency safeguarding, flak bunker, Hamburg, Germany

After WW II this bunker had purposefully been made inoperable by controlled blastings of the inner structure. We accompanied the reconstruction and conversion into a power plant.

Crane runway, Bremen, Germany

Project information

Property type: Crane runway
Component: Reinforced concrete beam
Motivation: Damages
Service: Hybrid statics

Crane runway, Bremen, Germany

More than 90 years of crane operation and the handling of agressive potash had left heavy traces on this reinorced concrete structure. We checked whether it is permissible to keep up operations until the structure can either be overhauled or replaced by a new construction.
