Rose Bowl Stadium
The Rose Bowl, which opened in 1922, was replaced with a concrete structure in the 1930s. Home to the UCLA Bruins and the NCAA Rose Bowl game, the stadium has been expanded and modified over its lifetime. It currently accommodates nearly 100,000 fans and is designated as a National Historic Landmark. SGH assessed the condition of the concrete structure and the concrete overlay and later investigated cracking in the cement plaster walls at the press box.
SGH surveyed seating riser concrete and concrete topping, tunnels, stadium exterior, and underside concrete of the seating areas, evaluating the concrete material deterioration, corrosion of reinforcing steel, and water infiltration. We recommended proactive and reactive concrete repair options for the owner’s consideration.
At the press box, SGH surveyed the exterior plaster cement walls and performed petrographic examinations on extracted samples. We identified cracking in the plaster due to shrinkage, exacerbated by the relatively large panel sizes and the use of a cement-rich mix. We recommended repairs, ranging from localized repairs to plaster replacement.
