5 million expansion and renovation of Collings Hall, and $2.55 million in improvements to the Sarkeys Energy Center. The newest Stephenson facility, a 160,000-square-foot building near the Stephenson Research and Technology Center on the south research campus, will house research labs, graduate study and support facilities for the chemistry and biochemistry department. Collings Hall is on the west side of the South Oval and houses the Jeannine Rainbolt College of Education. The Sarkeys renovation at 100 E Boyd St. will add space and features for the Mewbourne College of Earth and Energy. Two other expansion projects are due to be finished by early 2011, though it’s possible the $13 million Stuart Wing and Adkins Gallery additions to the Fred Jones Jr. Museum of Art could be finished late this year. The $33 million renovation and expansion of Gould Hall, the South Oval home of the College of Architecture, remains on schedule for completion in spring 2011. On the infrastructure side of capital projects, a $7.7 million expansion of the chilled water plant to accommodate the ever-developing south research campus is expected to be completed in summer or fall. A new utility plant for the main part of campus, budgeted to cost $72 million, is scheduled to be done in fall 2011. A new project this year, Zarrow Hall, which will house the Anne and Henry Zarrow School of Social Work, is expected to break ground where the Jim Thorpe Center stands.
