SAN DIEGO-CalMat has sold two office buildings in Mission Valley totaling more than 175,000 sf to the acquisition-hungry Shidler Group in a deal valued at $22 million.

The Orange County office of Cushman Realty Corp. handled the sale of Rio Vista Plaza, a 78,162-sf building at 8989 Rio San Diego Dr., and the adjacent Rio Vista Building, which is 97,500 sf.

“CalMat is concentrating on the aggregate and concrete business, not real estate development,” says Peter Andrich, the senior director for Cushman who handled the transaction.
