Decisions about where the new Georgia Poultry Laboratory Network headquarters will be built, or when, are still up in the air.In the works for several years, the $13.5 million project was supposed to be completed this fall, replacing the current building at 4457 Oakwood Road, Oakwood.“The state has reviewed numerous sites for this project,” said Paul Melvin, spokesman for the Georgia Building Authority.The main criterion for the new headquarters, Melvin said Thursday, is that it would be built in Hall County, preferably in the Gainesville area, with a site near Ga. 365. Also, the state is looking for 10 acres in a nonresidential area.One of the reasons the state decided against building on the longtime Oakwood site is that “the nature of the surrounding area has turned residential and is not appropriate for the construction of a new poultry lab.”Also, the project’s construction budget is $11.26 million and the lowest bid for building at the Oakwood site was $12,775,000.“One of the primary reasons the bids were higher was due to site issues such as topography,” Melvin said.The first state lab was built in Gainesville in 1946, moving to Oakwood in 1962.Over the years, growth in the industry has created space issues at the 12,000-square-foot lab in Oakwood. At one point, part of the single-story red brick building was condemned, creating even tighter space issues.And then, because of the economic downturn, the network closed branch labs in other parts of the state.“We’re really anxious to get into this new lab, there’s no question about it,” said Louise Dufour-Zavala, executive director.
