ZÜBLIN takes on structural work for reconstruction of historic town hall in Straubing
- ZÜBLIN Subdivision Bavaria awarded first two partial contracts for structurally complex building project after fire damage
- Ambitious project foresees extensive modernisation behind existing neo-Gothic façade
ZÜBLIN has been given a leading role in the reconstruction of Straubing’s historic town hall in the heart of the city. Following the first partial contract awarded in the summer, Ed. Züblin AG has now also received the contract from the city of Straubing for Section 2 of the structural work on the complex project. The value of both partial contracts totals € 3.2 million. With these contracts, the project team from ZÜBLIN Group Straubing has handled all structural work that has been put out to tender so far – from the complete renewal of the building foundation to the new construction and conversion of two staircases.
The four-part building complex, parts of which are more than 600 years old, was severely damaged by a fire five years ago and is now to be restored to its usual exterior appearance with its 1893 heritage-listed neo-Gothic façade, but extensively remodelled to modern standards on the inside. Besides an additional staircase with lift and a foyer, the town hall will receive a new, third floor by converting the previously unused attic space for the town council meeting room. The city of Straubing has placed the planning and coordination of the entire project in the hands of renowned architectural firm Hild und K. All trades will be successively put out to tender individually as construction progresses. Archaeological investigations on the historical building site are being carried out in parallel to the earthworks and will precede the structural work.
ZÜBLIN to reinforce structural integrity of town hall foundation
“We are delighted to be able to contribute the capabilities of Ed. Züblin AG to this publicly acclaimed lighthouse project in Straubing. The work for this ambitious construction project involves a number of challenges which we are happy to meet,” explains Eduard Holzapfel, technical manager of ZÜBLIN Group Straubing, Subdivision Bavaria. The necessary improvements to the building structure present the ZÜBLIN project team working on Section 1 with a complex task, as the additional load from the planned heightening of the building and the new interior fittings, including the technical building equipment, require a comprehensive reinforcement of the town hall foundations. The floor slabs are being completely renewed, and the historic brick and quarry stone foundations of the walls will be reinforced with concrete supports. The town hall will also receive additional pile-head beams made of reinforced concrete in the foundation to transfer the loads from the upper floors to the special micro-pile foundation by integrating them into the existing wall piers.
Section 2 comprises the construction of a new staircase core with lift, to be preceded by extensive demolition and stabilisation measures. The contract also involves the heightening of the heritage-listed sandstone staircase – highly demanding, high-precision work in which the historic structure has to be faithfully reproduced with matching formwork and reinforced concrete.
