Orange County Convention Center Phase V Expansion


The fifth expansion of the Orange County Convention Center nearly doubled the total size of the facility, making it the second largest convention center in the United States and one of few with the capacity to attract the mega-shows that all cities covet. The new stand-along Phase V structure provides over one million square feet of exhibition space as well as 94 meeting rooms, four food courts, four dining restaurants, a 10,000-car parking garage and two 1,000 foot-long glass-walled pre-function concourse areas. It is physically connected to the rest of the complex by a 1,400-foot long exposed steel pedestrian bridge that spans across two roadways and provides moving walkways for conventioneers. 

As lead structural engineer, Walter P Moore turned the architect’s vision for grand arched entries into efficient and elegant exposed structures that give the venue its distinctive, welcoming look. The project team worked under an extremely aggressive schedule, delivering the massive structure in just 42 months.
