Lessons Learned From the Tappan Zee Bridge, New York

This report examines the feasibility of using precast construction in deck replacement by drawing upon the lessons learned from deck replacement projects that have taken place on the Tappan Zee Bridge in New York. The report first provides a detailed overview of the deck replacement and installation procedures used on the Tappan Zee Bridge. It then outlines those issues that should be considered for similar projects: 1) careful planning for issues such as traffic management, contractibility issues, crane capacity, contractor's technical and construction skills, time management, and staging construction; 2) attention to details; 3) traffic control; 4) brainstorming as a group; 5) giving consideration to future rehabilitation options; 6) availability of backup construction equipment and trained personnel; 7) conducting a trial run of the construction operation; and, 8) design and field verification. Other areas for consideration are identified, such as choosing an optimum size of operation, crew, area of deck replacement, and timeframe; looking into weather patterns; and choosing appropriate concrete material and curing patterns.
