Thanks to all who joined the ASCE Cincinnati Section and the ASCE Geotechnical Group for a presentation about the geotechnical challenges of a new Costco Wholesale warehouse project in Atizapán, Mexico. Joseph Kowalski, P.E. presented on the project that included a variety of walls, geopiers, tieback anchors, and other measures to develop a challenging 12-acre site. The project included a variety of geotechnical work because the site varied by more than 130 feet in height and contained low-quality soils.  The project included:
  • Steel-reinforced MSE wall that was up to 26 feet tall
  • A series of tiered walls consisting of tie-backs and cast-in-place concrete
  • Tieback anchors between 30' to 50' long
