Description of Work:
The Olympic Boulevard Bridge, one of twelve historic bridges over the Los
Angeles River, was a 1,420 feet reinforced concrete, open spandrel structure.
Built in 1925, it was named in commemoration of the 1932 Olympic Games held in
Los Angeles. The Bridge has continued to be an important link in the City's transportation
system, permitting truck traffic flow in and out of Downtown Los Angeles.
The Bridge was reconstructed to meet current seismic codes and to restore the original architectural elements. New construction included the construction of longitudinal and transverse infill walls and new spread and steel pile footings. The retrofit work included strengthening of the abutments through reinforced concrete and hinge pipe restrainers. The historical work involved building the original architectural handrail, lampposts, and lighting fixtures. Finally, a maintenance facility building located underneath the west end of the bridge was demolished and reconstructed.
This project was a success for both the contractor and the owner for several reasons. The project was completed on time. Through value engineering of new sidewalk in lieu of spall repair, NSJV credited $500,000 back to the owner. Finally, the project was completed with total change order costs contributing less than 4.5% beyond the original contract amount.
