Temporary Shoring & Permanent Structural Walls for Underground Pedestrian Station Using Giken ECO 1400 Silent Piler and Giken Simultaneous Auger for the Las Vegas Convention Center in Las Vegas, Nevada
Steel Sheet Pile was installed using the Giken Silent Piler as a temporary shoring system to allow excavation of the Las Vegas People Mover underground pedestrian station. As temporary shoring, the 53-foot long NZ38 sheet piles were installed to retain a 35-foot excavation prior to installation of the station. Once excavation was complete the steel sheet piles were used in the final design to act as the structural walls of the Convention Center Campus-Wide People Mover. The Giken Silent Piler was selected due to the soil conditions on site which contained layers of caliche typically impenetrable with conventional sheet pile installation methods. By selecting the Giken Silent Piler and Giken Simultaneous Auger Crush system we were able to auger thru the caliche layers and successfully install the sheet pile to the designed tip elevation. In addition, the Giken Silent Piler meets the City of Las Vegas requirements which limits the installation of piling with noise and vibration. Lastly, the Giken Silent Piler is able to precisely install sheet piles which were required due to the permanent end use of the piling as the structural walls of the Las Vegas People Mover.

Sheet Piling Borehole Data
Borehole data provides soil classification and measurements of density, moisture content, and groundwater levels from boreholes drilled into the Earth at project locations. Las Vegas Nevada geology typically consists of clay’s, sandy gravels and most notable layers of caliche and high groundwater. The Giken Silent Piler & Giken Auger Crush was used at the Las Vegas Convention Center to allow the sheet pile to penetrate through 3 layers of very hard caliche along with very stiff clays and dense sand. We successfully installed NZ38 sheets to 53’ below ground surface to complete the project on time and within tolerance.
- Seafloor Layers: 2
- Seafloor Material 1: Silty Fine Sand
- Seafloor Material 2: Dense Shelly Sand
- Borehole Depth: L=30ft – 35ft.
