The biggest new architecture project in Los Angeles just got a much smaller list of candidates. The General Services Administration (GSA) has released the shortlist for the new U.S. Courthouse in LA, a design-build project where architects are partnered with builders. When completed, the building, located on a 3.7 acre lot at 107 South Broadway, will measure 600,000 square feet. It’s projected to cost $322 million and be completed by 2016.

The shortlisted teams include:

Skidmore Owings and Merrill with Clark
Yazdani Studio and Gruen Associates with Hensel Phelps
Brooks + Scarpa and HMC Architects with McCarthy
NBBJ Architects with Mortensen

Shortlisted firms will now be expected to submit plans as part of a Request For Proposals. The winner is expected to be named by this August or September, and design is set to begin by the end of this year.

Those who didn’t make the cut included Morphosis, Michael Maltzan Architects, Ehrlich Architects, AC Martin, Johnson Fain Architects, Fentress Architects, Rios Clementi Hale, and Cannon Design. Another exclusion was Perkins + Will, who GSA originally chose to design the project before it stalled several years ago.
