The modernization of the auditorium and gymnasium for LAUSD�s Eagle Rock High School, which was built nearly 100 years ago, featured extensive seismic retrofitting and included more than 30,000 cubic feet of compaction grouting, HVAC modernization, and the construction of new lockers, flooring, bleachers and seating. The project challenges were met head-on through a collaborative partnership with our subcontractors, LAUSD and the three design teams that worked concurrently and were each responsible for a separate DSA package. As a result of pre-planning and partnerships, the team met the challenge of compaction grouting in rooms with raised floors, limited access and varying grades. The structural upgrades also included extensive coordination of abatement and Fiber Reinforced Polymer work.
