The single largest contract ever awarded in Pacific Northwest National Laboratory's (PNNL) history was signed to complete construction of the Physical Sciences Facility (PSF).
The PSF is an approximately 200,000 sq. ft. complex located on the Horn Rapids Triangle just north of the PNNL campus in Richland, Wash. It is part of PNNL's strategy for replacing nearly 500,000 sq. ft. of office and laboratory space, due to the demolition of many of the Hanford Site's 300 Area facilities.
