A joint venture that includes a Spokane construction company won a $106 million contract to finish a nearly 200,000-square-foot research facility at the Pacific Northwest National Laboratory in Richland – the largest contract in lab history, according to the U.S. Department of Energy. Spokane-based Lydig Construction Inc. and George Grant Inc., of Richland, will complete three main buildings, a test track and an underground laboratory for PNNL's Physical Sciences Facility, according to a department news release. Work on the complex, northwest of Horn Rapids Road and George Washington Way, starts in July.
