ST. LOUIS, MO Metropolitan St Louis Sewer District (MSD) constructed approximately 100 lineal feet of 15” diameter combined sewer pipe and appurtenances. The project area is location in the alley near residential property 14 Washington Terrace St. Louis, MO 63012.
Since the project was located in a narrow residential alley with overhead and underground utilities, a third party utility location service provider was used for identifying “safe” location to drill. Gonzalez completed field investigation with a CME-55LC low overhead drill rig using conventional hollow stem auger drilling methods. One 25-foot test boring was drilled to collect data and samples for defining the subsurface profile and development of design parameters. We conducted laboratory tests to determine pertinent engineering and index properties of foundation soils. Tests performed included moisture content, Atterberg limits, and unconsolidated-undrained triaxial compression.
Our engineering analyses focused on observed subsurface conditions, excavation considerations, anticipated subsurface dewatering requirements, lateral earth pressures, and construction concerns.
