A team of water damage experts has been conducting a structural examination of the Mondavi Center for the past two weeks. The investigation is part of an effort between the campus and the performing arts complex general contractor, McCarthy Building Cos., to determine the source of water that has been leaking into the building during rainy weather. The facility designers, BOORA Architects, are also assisting in the investigation.

The leaks, which were most pronounced during the wind and rain storms earlier this month, are primarily in the south side of the building and have not affected the performing spaces, according to Susan Rainier, a senior project manager for the Office of Architects & Engineers who is now overseeing the investigative work.

There has been no water damage that has impacted operations or programming at the Robert and Margrit Mondavi Center for the Performing Arts, according to John Dorsey, director of facilities for the center. "We are operating normally and the performance space is sound," Dorsey said.

"The university is collaborating with the contractor to conduct an extensive water intrusion investigation for a full assessment of the problems, to make obvious repairs and to develop a plan for other fixes determined to be necessary when the investigation is completed," Rainier said.

Because the Mondavi Center, which opened in 2002, was constructed as a "building within a building" with thick walls for extremely effective soundproofing, the performing spaces are within an interior shell. The leaks have largely affected the first "box" shell, and the interior spaces have not been impacted, Rainier said.
