The General Services Administration this week identified 19 federal buildings across the nation that will absorb outside offices as part of a nearly $70 million plan to consolidate agency work sites.

The project will cost about $67 million up front for renovations, but it will save the government an estimated $17 million annually in rent payments, while eliminating leases and reducing square footage requirements, according to a GSA announcement.

Many agencies operate out of multiple offices in a single region, but GSA plans to move some of those work sites into existing federal properties.

As part of its plan, the agency has tapped four offices in the Washington region for renovation, including the Hubert H. Humphrey and Mary E Switzer buildins in D.C., the George H. Fallon Federal Building in Baltimore, the Science Applications Court in Vienna, Va., and the Norfolk Federal Building in Norfolk, Va.

The revamped facilities will feature “open work spaces,” much like the recently updated GSA headquarters in the nation’s capital. The layouts emphasize large, open and flexible spaces rather than the traditional setups with cubicles and offices.

“By consolidating these locations, we are not just eliminating redundant rents and space, but also encouraging collaboration among government workers by creating open workspace,” GSA Administrator Dan Tangherlini said in the announcement.

Congress and President Obama this year approved a 2014 appropriations bill that provides $70 million for the 19 consolidation projects. The GSA’s 2015 budget request asks for another $100 million for similar plans.
