Nine and a half acres may sound like adequate space for a 70,000-sf building, but when that acreage is shoehorned into a narrow corridor, problems can quickly arise. Such was the case for the LA Metro Division 14 Expo Light Rail Operations & Maintenance Facility.

To make the building site work, the design team needed to make as efficient use of the space as possible. Building spaces overlap over the rail yard and maintenance area and 34-foot-long moment frames span two tracks. Part of the building’s main hallway hangs over the maintenance area, as well.
