The mid-sized company AUER Packaging GmbH is one of the leading German manufacturers of transport and warehouse products made from plastics. BAUER Spezialtiefbau GmbH was tasked with the execution of foundation works for a new high-bay warehouse to expand the Bavarian production plant in Amerang. Within a five-week construction period, a total of 552 micropiles with a diameter of 270 mm were installed using the continuous-flight-auger method.

The CFA method is a rotary drilling technique that uses an auger as drilling tool. Once the tool reaches the final depth, the hollow stem auger concretes from the bottom up. The drilling depth at the construction project in Amerang was 11 meters. Additionally, GEWI threaded rods were fit into the drilled and concreted CFA piles and set as an uplift prevention. A projection of 0.65 m was calculated for the GEWI head structure.

Due to the various and unfavorable ground conditions, tensile tests were carried out on 16 test piles in the run-up to the actual foundation works. The soil conditions at the construction site were gravelly to soft or mushy. Unbreakable boulders found in various depths also demanded a quick response

The tight construction grid of 3.2 m meant that the production sequence needed to be precisely planned and coordinated so that the drilling work executed with a BAUER BG 20 H drilling rig would not be impeded due to already installed GEWIs. The works carried out by Bauer with a total of 6,072 m drillings were successfully completed at the end of March.
