Tectonic is providing Quality Control (QC) services for the construction of the new Tappan Zee Hudson River Bridge as sub-consultant to Tappan Zee Constructors, LLC – (TZC), the team of Principal Participants Fluor Enterprises, Inc., American Bridge Company, Granite Construction Northeast, Inc. and Traylor Bros., Inc. As an integral part of the TZC team, Tectonic is responsible for all components of special inspections and materials testing, Including:
The existing bridge is an essential component of the regional roadway network connecting Rockland County with Westchester County and providing integral access to the New York Metropolitan Area. The new Tappan Zee Hudson River Crossing is designed for a 100-year service life and will be mass-transit-ready. It features twin three-mile structures, each with 1,200-foot cable-stayed main spans and 350-foot steel girder approach spans. The new bridge provides eight general traffic lanes, emergency lanes, extra-wide shoulders for express bus service, a dedicated bicycle and pedestrian path on the northern span, and scenic overlooks with anti-climb fencing and security cameras. A new toll plaza will include at least three highway-speed E-Z Pass lanes. The project also includes plans for the approximately 35 existing buildings associated with the bridge. The design-build approach produced a savings of $1.7 billion compared with original state and federal cost estimates and is scheduled for completion in 2018.
