Nicholson Construction was recently awarded a secant pile wall contract for the Maline Creek combined sewer overflow (CSO) project in St Louis, Missouri. Their scope of work will include 78 880-mm (~3-ft) piles to depths of 40 to 50 feet, 114 880-mm secant piles to approximately the same depth that will form a braced excavation. They will also install 4 seven foot diameter jet grout columns beneath an existing sewer to support it during excavation. [Source: More about the project at NicholsonConstruction.com.
