WHAT HAVE BEEN ACCOMPLISHED:

The project included designing a $90 million elevated circulation roads connecting I-101 and the new SFO international airport.

As part of the design team for the SFO Airport Expansion Project, JMEC was responsible for the design and the PS&E for a section of Elevated Circulation Roads including Frame 1 and Frame 5 which connect to the new Airport Inbound and Outbound Ramps.  The superstructures were constructed of CIP prestressed box girders.

The unique features of this project include:
  • Coordinated with other SFO contracts including the Inbound/Outbound Ramps and the People Mover (ALRT)
  • Designed several combined footings supporting the structures of Circulation Roads, Inbound/Outbound Ramps, and the ALRT
  • Column design was based on displacement ductility and push over  analyses
  • Designed box girder with transition from curved web to trapezoidal web
  • Designed structure with complex branching
  • Prepared early foundation contract to expedite the construction
Project Role:  Subconsultant for Bridge Design

Clients:  City and County of San Francisco
               Parsons - OPAC - AGS Association
Special Issues:  Working in close liaison with Caltrans, ALRT, and other design consultants, three special foundations were designed to support 3 different structures (from 3 different design contracts).   Resolved Frame 1 and Frame 5 complex geometry at transition.

Schedule:  Construction was completed in 2000
