ASCE August Luncheon: The New East Span SAS Bridge: A Community’s Passion for Innovation & Aesthetics
The new self-anchored Bay Bridge is the longest span bridge in its class as a single tower, self-anchored suspension bridge. An iconic bridge design with a modernistic look represents Bay areas’ passion for innovation & aesthetics. It is an example of engineering ingenuity as its design, fabrication, and erection were challenging due to its three-dimensional cable erection with sloping hangers to support the orthotropic steel deck eliminating massive gravity anchors thereby minimizing its footprint on the Bay.
Speaker: Ajay Sehgal, PE is currently a Branch Chief in Caltrans District 04 Encroachment Permits Office. He was a senior bridge engineer and falsework specialist in the Office of Structure Construction, Bridge Department, at Caltrans. Mr. Sehgal guided the design & construction of falsework, scaffolding, bridge trestles, trenching, shoring, and demolition. He updated the FW Trenching & Shoring Manual, and he was the point person working with the railroad (RR) companies to get the approval of temporary structures for Caltrans projects within or adjacent to the RR.
Mr. Sehgal started at Caltrans 31 years ago in 1988 when he worked on the Schuyler Heim vertical draw bridge in LA. In 1995, he worked on the seismic retrofit of the Presidio Viaduct in San Francisco southern approach to the Golden Gate Bridge. In 1996, he continued to work in San Francisco on the Eastern Approach to the Bay Bridge. In 2008, he worked on the new Self-Anchored Suspension Bay Bridge.
