The company Kurt Motz Baubetriebsgesellschaft GmbH & Co KG is carrying out foundation work for a new production building for the "Integrated Technology Center (ITC)" at the premises of Airbus Defence and Space, a division of the Airbus Group. Two Liebherr drilling rigs type LB 28-320 and LB 36-410 are in operation for the contracted deep foundation company in Immenstaad. The machines are part of a package of six new Liebherr LB devices for the company Kurt Motz. The official handover took place directly on the Airbus jobsite.

Using Kelly equipment the machines are installing cased drilled piles for the foundations of the new building, which is an extension of the technology centre and measures approximately 70 x 60m. The single piles are 40 metres long and have diameters of 750 and 900mm.

Foundation work involves a total drilling length of 7900m. A particular challenge is posed by the closeness to Lake Constance. In order to avoid groundwater and seawater a sheet pile wall was erected using a Liebherr piling and drilling rig type LRB 125.
