Sacramento Community Theater

CLIENT City of Sacramento

Location Sacramento, CA

This renovation project includes the expansion on three sides of the existing two-story theater. A portion of the  structure will span over an existing tunnel between the theater and the adjacent Sacramento Convention Center.

Shannon & Wilson completed studies for both a geotechnical engineering design report and a geologic hazards report for the project. Our services included recommendations for pile foundations, seismic design parameters, external low retaining walls, pavement design, exterior flatwork, and utility trench backfill. To reduce costs to the client and disturbance from geotechnical explorations, Shannon & Wilson used existing geotechnical borings from the original construction and adjacent projects. We augmented this data with selected cone penetrometer tests (CPTs).

The proposed building will be pile supported to mitigate potential differential settlement between the existing and new structure. We recommended using concrete-filled, drilled steel pipe piles (also known as torque-down piles) to reduce potential adverse effects of noise and vibrations at and adjacent to this urban site. These piles are full displacement piles that are screwed into the ground rather than driven piles.
