He was also the senior structural engineer/reviewer for the Tappan Zee Bridge (Governor Mario M. Cuomo Bridge) D-B project in New York, one of the largest single D-B contracts for a transportation project in the United States. His role included providing review comments on approach structure plans for the Rockland and Westchester approaches and directing the evaluation of the precast decks and closure pours at the approach spans for cracking issues.
Sivakumar’s ABC projects include serving as Project Manager and lead ABC design engineer for the award-winning Rapid Replacement of Twin I-84 Bridges project in Brewster, New York. The project replaced two twin bridges that were designed to allow the work on each bridge to be completed during a single weekend night using the lateral slide movement technology.
