Design Challenges of a Mid-Rise Hotel on an Active Fault

By Pavlo Chrysovergis, P.E., ASCE OC Geo-Institute Chair

The Orange County Geo-Institute Chapter hosted an August dinner meeting in Costa Mesa featuring a presentation by Dr. Marty Hudson and Ms. Rosalind Munro of Wood Group.  The presentation focused on the geotechnical and geological challenges associated with the design and construction of a mid-rise hotel project built on an active fault in Hollywood.  The presentation covered fault investigation, probabilistic fault rupture displacement hazard analysis, an innovative fault moat, and challenges with shoring and tension piles.  The meeting was attended by over 90 local practicing engineers, academics, and students.  Thank you to our sponsors: Hayward Baker, Western Ground Improvement, NorCal Geophysical, GeoVision, Tencate Mirafi, and Rite Geosytems.
