Covance to shut Vienna office, cancel office park Biotech contract research firm Covance Inc. will shutter its Vienna toxicology facility and has scuttled plans to build a new $175 million lab complex in Prince William County’s technology park.

The Princeton, N.J., company cited a weakened market for outsourced toxicology services as the reason behind its decision to close the 112,000-square-foot Vienna location, part of a broader set of cost-saving measures that Covance said would save $40 million in 2011. The company announced a net third-quarter loss of $30.9 million, or 49 cents per share.
