Rose Bowl Operating Company
Pasadena, California
Major renovations and improvements were made to the Rose Bowl Stadium, with the objective of improving public safety, improving facility operations, and maintaining the stadium as a National Historic Landmark.
Earth Systems performed surface and shallow subsurface exploration of the site and tested soils samples in our laboratory for characteristics such as moisture and density, grain size distribution, relative strength, and consolidation. Percolation testing was conducted off-site for storm-water disposal. Geotechnical engineering analyses were conducted for liquefaction, earthquake-related settlement, slope stability, bearing capacity and load-deflection relationships for both deep and shallow foundations.
Our study also entailed evaluation of the geologic setting and site seismicity and assessment of geologic hazards that might affect the Rose Bowl. A geophysical survey was conducted using refraction microtremor data reduction techniques to estimate the physical properties of subsurface materials and characterize the site for seismic design.
