For a new residential district in the Rödelheim quarter of Frankfurt, the general contractor for the excavation pit, BST Becker Sanierungstechnik GmbH, hired Stump-Franki Spezialtiefbau to handle all the specialist civil engineering for a complex excavation pit. The services included the construction of an overlapping bored pile wall, as well as sheet pile walls with various profiles and bracing, in two construction stages. Stump-Franki Planung GmbH was responsible for planning the implementation.
Urban Living with a Connection to Nature
The VIDO residential district in Rödelheim is located to the west of Frankfurt city center and comprises 166 high-quality condominiums with a total of 13,300 m2 of residential space, distributed throughout 12 buildings. Each building has an underground parking garage, and virtually all the apartments are equipped with either a terrace, a balcony or a loggia.
Complete Specialist Civil Engineering Service – Safe and Economical Implementation
The dimensions of the site were about 110 m × 45 m for the first construction phase, and about 53 m × 68 m for the second construction phase. To protect the excavation pit, 6300 m2 of water-blocking steel sheet pile walls were installed, braced with waling, as well as temporary strand anchors. Due to different static cuts, multiple sheet pile wall profiles were used. To protect the neighboring buildings, the other half of the excavation pit was enclosed with overlapping bored pile walls and braced with abutment piles.
Stump-Franki’s experts brought all their expertise to bear in ensuring economical, on-schedule construction of the excavation pits. Optimizing the shoring line reduced the area of the sheet pile walls and the construction time. Since the two excavation sections were constructed independently of each other, the work had to be carried out on a reliable schedule.
