Since 2007, the US Army Corps of Engineers (USACE) has been responsible for coordinating the rehabilitation of the 225km dyke around Lake Okeechobee. Between 2007 and 2013 Bauer Foundation Corp., the American subsidiary of Bauer Spezialtiefbau, was first commissioned with the execution of cutter soil mixing sealing walls for the rehabilitation of the first sections of the dyke. The success of that operation led Bauer to receive additional partial orders for the years 2011 to 2021, including the replacement of various duct passages.

The subproject 'Culvert 12 for Thalle Construction' was implemented using a Bauer BG 28 drilling rig in the cutter soil mixing process (CSM), combining features of the trench wall technique and the mixed-in-place process. Due to the dense soils, initially, a pre-drilling was carried out and then carried out using a modified and powerful router soil mixing.

In February 2016, Phase 1 of the project could be completed, however, pre-drilling was not necessary, since the dense peat layer could be removed before. In total, 12 CSM panels were produced down to a depth of 11m during this first phase. Work on Phase 2, involving 214 pilot holes down to a depth of 22m and 83 CSM panels, lasted from June to the end of August 2018. The subsequent test phase is expected to be completed by the end of September.
