RJ Watson has manufactured 473 high load multi-rotational Disktron Bearings for the $4.2 Billion reconstruction of Terminal B (also known as the Central Terminal) at the LaGuardia Airport in Queens, New York.
Disktron Bearings are being installed on 15 vehicular bridges, the Concourse B pedestrian bridge, and the level 5 roof structure. The bearings range from 66 kips (294 kN) of vertical service load to 3,200 kips (14,235 kN) of vertical service load. The horizontal service load for these bearings range from 10% to 40% of the vertical service load. They are designed to accommodate 3” (76.2mm) to 14.5” (368.3mm) of longitudinal displacement, and between 0.375” (9.5mm) to 9” (228.6mm) of transverse displacement. The disk bearing strength rotation is 0.02 radians.
22 of the disk bearings have been designed to accommodate uplift forces of 34 kips (152 kN) to 600 kips (2,669 kN) of uplift strength load.
The project was awarded by the Port Authority of New York and New Jersey to LaGuardia Gateway Partners, a joint venture consortium comprised of Skanska USA Civil, Walsh Construction, Meridiam Infrastructure, and Vantage Airport Group, with HOK, and WSP Group making up their design team.
This Public Private Partnership project officially began in 2016, and it is scheduled to be completed in 2020. As part of the Public Private Partnership agreement with the Port Authority of NY & NJ, The LaGuardia Gateway Partners will be responsible for operation and maintenance of Terminal B until December, 2050.
