Corridor 2 (the second corridor north of Constitution Avenue NW). Phase 4 — Renovation of the interior and replacement of the roof on Corridor 3 (the third corridor north of Constitution Avenue NW). Phase 5 — Renovation of the interior and replacement of the roof on Corridor 4 (the fourth corridor north of Constitution Avenue NW). Phase 6 — Renovation of the interior and replacement of the roof on Corridor 5 (the fifth corridor north of Constitution Avenue NW). Phase 7 — Renovation of the interior and replacement of the roof on Corridor 6 (the sixth corridor north of Constitution Avenue NW). Phase 8 — Renovation of the interior and replacement of the roof on Corridor 2 (the corridor parallel to Pennsylvania Avenue NW). GSA's Federal Building Fund will contribute $605 million toward the renovation, while the Department of Commerce's contribution is $128 million. Another $225.6 million, provided by the American Recovery and Reinvestment Act of 2009, funded Phases 2 and 3. Both GSA and the Department of Commerce contributions are dependent upon annual congressional appropriations. The Great Recession provided GSA with $40 million in savings.

By late 2012, however, budget cuts led to an indefinite delay in completing the project. Nonetheless, GSA pressed ahead with plans in February 2012 to create a more secure barrier around the Herbert Hoover Building. GSA proposed a steel cable barrier concealed by stone cladding, deep-buried steel piers, and collapsing sidewalks. Beautification elements included two reflecting pools along 14th Street NW, which would include public seating and Capital Bikeshare stations. Design and art The building is rectangular and measures approximately east to west and north to south. It forms almost the entire west side of the Federal Triangle from Constitution Avenue to E Street. The building contains more than 3,300 rooms joined by unbroken corridors long.

The New York Times has described it as "sprawling." The Malcolm Baldrige Great Hall (named after Howard M.
