The contract work in Queens Bellmouth included closure and backfill of the existing open tunnel structures and backfill of the structures and the site.
The scope of work also included structural precast fit-out of two 1000-foot existing caverns with 830 precast beams, 844 precast panels, 694 precast walls, and 370 precast platforms.
Track work consisted of 52,000 track feet of RTB Tieblock construction, 14,000 track feet of direct fixation construction, 64,000 linear feet of contact rail installation, 32 turnouts, 52 switches, double cross-over construction, and 35,000 cubic yards consisting of track bed concrete, traction power, and signal conduit installation.
