About the project

Walter P Moore provided complete structural engineering for the Phase III expansion of the Orange County Convention Center. The facility is constructed of structural steel and reinforced, cast-in-place concrete with a long-span steel roof and concrete floors. One million square feet of new exhibit hall, meeting rooms, lobbies, food service and administrative areas, and support/mechanical areas were added. Additional components include a 2,500-seat auditorium, a 60,000 SF ballroom, a business center, and a plaza.

The Orange County Convention Center has enjoyed remarkable success since its opening in 1983. Since 1984, the facility has operated at capacity, and future bookings indicate a strong demand for the facility. The center hosts various meetings, including conventions, trade shows, assemblies, and consumer shows.
