Presenter:
MARTIN BODEMAR, S.E.
Martin Bodemar has over 24 years of experience in Project Management and Structural Engineering. Martin works on a wide variety of structural projects with a special emphasis on unique bridge designs including concrete box girders, steel trusses, arch bridges, and stage-constructed bridges. During his 19 years at Biggs Cardosa Associates, Martin has led the design of many multi-disciplinary bridge projects in the California. His recent work includes leading the quality control for the structural design of the approach bridges and bifurcating ramp structures for the replacement of the Gerald Desmond Bridge near the Port of Long Beach. In his spare time, Martin enjoys various outdoor activities including biking, running, hiking, snowboarding, and others.

GERALD DESMOND BRIDGE APPROACHES, PORT OF LONG BEACH, CA
The low level approaches consist of long-span post-tensioned box girder bridges with most spans exceeding 200 feet. These structures are similar to Caltrans’ standard box girders. The low level approaches include bifurcations for the various ramps that occur at the ends of the bridge project. The bridge frames with column heights of approximately 70 feet or less are considered “low level approaches”.
The high level approaches consist of primarily single-cell box girder superstructure supported by hollow rectangular columns. The superstructure was modeled and analyzed considering stage-construction and time-dependent effects due to the span-by-span construction method used. The span-by-span construction was used to accommodate a movable scaffolding system as a replacement for traditional falsework. With very tall columns (ranging from 70’ to approximately 150’ in height), traditional falsework construction methods were not economical for the high level approaches.
