TZC: Load Testing for Test Pile Program Begins (USA)

Load Testing for Test Pile Program Begins

Tappan Zee Constructors, LLC (TZC) will begin testing both static and lateral loads this week as part of its test pile program.

These load tests are performed to ensure piles are capable of sustaining the design load of the new bridge. Testing will be conducted over a 40-hour period.

Impact pile driving will continue this week as part of the ongoing test pile program and will continue through October at various locations for future pile foundations. This work will be performed from 7 a.m. to 7 p.m. on weekdays and, at times, on Saturdays from 12 noon to 7 p.m. The test pile program will verify subsurface conditions and test structural load capacities in preparation for construction of the new bridge’s permanent foundation.

Overnight lane closures will also be required in both directions on I-87/I-287 and the Tappan Zee Bridge due to various construction activities.

TZC will continue dredging operations in the Hudson River as part of the New NY Bridge Project. Dredging will occur through October 31 to avoid negatively impacting migration and spawning patterns of local sturgeon populations and other fish species.

Dredging crews will work 24 hours a day, seven days a week starting from the main navigation channel end of the dredging footprint towards the shoreline on both the Rockland and Westchester County sides of the bridge. The operations will deepen the river’s shallow water level in the work zone by removing sediment from the river bottom. The dredged materials are being properly disposed of at offsite locations.
