WorldWide Drilling Resource

30 FEBRUARY 2022 WorldWide Drilling Resource® Excavation and Installation Excellence in Bavaria Compiled by the Editorial Staff of WorldWide Drilling Resource® Wolfratshausen, Germany, a Bavarian town approximately 18 miles south of Munich, and around six miles east of Lake Starnberg, is seeing new construction carried out by BAUER’s Specialist Foundation Engineering Team. The future “Loisach Quartier” will consist of a residential complex with additional commercial spaces. Plans for the southern section include construction of a new supermarket and 47 apartments, as well as a two-story underground garage. The northern section will include an apartment building with 70 apartments and another underground garage. BAUER Spezialtiefbau GmbH, was tasked by the client, Loisach Quartier GmbH & Co. KG, with construction of the required excavation pit. The company carries out specialist foundation engineering work for complex excavation pits and foundations on major infrastructure and building projects, installing cut-off walls and carrying out ground improvement works, as well as providing related project development services. Michael Doll, project manager at BAUER explained, “In total, we will construct 59,000 square feet of static mixed in place (MIP) wall up to a depth of 74 feet.” He added, “Roughly 16,000 square feet of sheet pile walls will be executed up to a depth of 72 feet to ensure the underground flow of groundwater after the construction project has finished. After the uplift prevention has been achieved, these will be pulled out again.” The works also include the construction of over 8000 square feet of king pile wall with wood and shotcrete paneling, over 1500 running feet of anchors with four to five strands, as well as bracings, micropiles, and a dewatering system. Two RG 25 rigs and an RG 19 rig were used to complete the MIP wall, the sheet pile wall, and king pile wall construction. A Klemm KR 806 rig was used for the anchor construction. Due to multiple changes in height, detailed sequence planning was required. In addition, the MIP wall was installed in partially consolidated soil. Photo courtesy of BAUER Group. C&G
