The U.S. General Services Administration last week awarded Jacobs Engineering Group Inc. the construction management contract for the renovation of the historic Federal Building at 50 United Nations Plaza in San Francisco.

The Federal Building at 50 UNP, which was originally designed by prominent local architect Arthur Brown, Jr. and completed in 1936, has not had a major renovation in its 75-year lifetime, the GSA said. The $122-million renovation project, funded under the American Recovery and Reinvestment Act of 2009, will convert the 350,213-sq-ft building into a high performance green building and is scheduled to be completed in 2013.

The project is broken into two phases, according to Traci Madison, acting regional public affairs officer for the GSA’s Pacific Rim Region. Phase I was the preliminary demolition and environmental remediation work. That portion of the project was recently completed by Hathaway Dinwiddie, the general contractor. Phase II is the renovation/construction that is on going now.

The seven-story steel frame and masonry Neo-Classical style building will get new windows, HVAC system, plumbing and electrical systems and life safety systems.

The historic building is listed on the National Register of Historic Places and is a contributing building to the San Francisco Civic Center National Historic Landmark District.

In October 2009, HKS Inc., in partnership with Architectural Resources Group, won a $7.9 million design contract.
