Project Marks Another Milestone as Pile Cap Installation Begins – Sheet Pile Driving Resumes on Rockland Landing

August 22, 2014

The installation of the new bridge’s pile caps will begin the week of Aug. 25. These caps will cover the foundation piles installed in the river, marking a major milestone for construction and moving the project one step closer to completion. The pile caps used on the New NY Bridge are unique – they begin as large hollow tubs which are formed and cast offsite. These forms weigh several hundred tons, and are barged to the project site for installation. Once in place, they will be filled with reinforcement steel and concrete.

Sheet pile driving will resume near the Rockland landing as Tappan Zee Constructors (TZC) has confirmed that additional noise reducing measures have lowered noise to allowable levels. These operations will occur on land and in the river at one of the closest piers to the shoreline.

TZC will also begin construction on the new bridge’s Westchester landing this week. TZC will drill holes into the bedrock for the foundation of the new Pier 43WB. This work will continue to the new Westbound Abutment in Westchester over the next few weeks. This drilling process will produce less noise than the impact pile driving alternative, and TZC has installed sound mitigation to further reduce noise levels for the eight-week operation.

Construction will continue in the Hudson River as crews place the foundation for the New NY Bridge. Work will include pile driving between 7 a.m. and 7 p.m., Monday through Friday and 12 noon to 7 p.m. on Saturday.

A second shift of workers will also continue pile welding, pile cleanout and concrete placement operations associated with permanent foundations.

Work will continue on the Rockland work trestle near the shoreline, including pile driving. The trestle will support equipment used for the construction of the western-most section of the new bridge. Supportive excavation work will also continue at the new Westbound Abutment in Rockland.

The U.S. Coast Guard has established a Safety Zone surrounding 16 construction barge mooring locations at the project site. No unauthorized vessels are allowed in the Safety Zone. In addition, marine law enforcement will be enforcing the rules of the expanded Regulated Navigation Areas (RNAs) east and west of the Safety Zone. The RNAs stretch 500 yards north and 500 yards south of the existing bridge. Boaters are urged to transit the main channel with no wake at a maximum speed of five knots, and to use extreme caution on the river at all times.

More New NY Bridge boater safety information, including the U.S. Coast Guard Notice to Mariners, and construction site maps, can be found here at NewNYBridge.com. An interactive map showing vessel locations on the Hudson River is also available here for recreational and commercial boaters to get updated information on this very active construction zone. The GPS tracking map is for informational purposes and not intended for navigation.

Mariners should be aware that TZC will continue work in the vicinity of the side channels under the existing bridge. Additional temporary navigational lights have been installed to further define the 600-foot navigation channel under the main span. Permanent elements of the new bridge are lit per U.S. Coast Guard requirements, as are all moorings, barges and other equipment.
