One of Texas’ biggest contractors, Dallas-based Rogers-O’Brien Construction, claims it is owed $34 million by Microsoft Corp. for work on a problem-plagued new data center project in San Antonio.

The company made the claim in a lawsuit filed June 3 in federal district court in San Antonio. It blames Microsoft and an unnamed designer and vendors for failing to help correct the troubles. Microsoft has yet to answer with a reply to the complaint and a spokesman for the company could not be reached for comment.
