Sam Schwartz engineering recently released a schedule for Second Avenue subway construction through May 10.
Work surrounding the 96th Street Station includes the restoration of pavement and sidewalks between East 99th and 100th streets, starting May 11. Between East 97th and 99th streets, workers will be installing a 12-inch water main and excavating and installing a 30-inch gas main and splice boxes. Traffic will switch to the north side of East 97th Street to accommodate a gas main crossing. The excavation of a storm drain and backfilling of a sewer trench is also scheduled.
Workers will install a 30-inch gas main and an 18-inch sewer main at East 96th Street, as well as a 12-inch gas main and splice boxes. FaÃ§ade restoration work begins at 1873 Second Ave., a 100-year-old building with 12 studio apartments (tenants can remain in their homes during this portion of the work, but will have to temporarily relocate during more invasive work this summer). Relocation work for the FDR Drive ramp will begin.
Excavation and support for a 48-inch sewer main and manhole is scheduled on the west side of Second Avenue between East 95th and 96th streets. On the east side of the avenue, the sidewalk will be restored and reconfigured for the installation of an 18-inch sewer main. Test pits will also be dug for electrical work.
For the launch box area, between East 91st and 95th streets, tunnel boring machine assembly will continue. A conveyor system for the machine will be installed between East 92nd and 95th streets. In addition, workers will operate ground water control systems between East 93rd and 95th streets, and conduct excavation work and begin concrete pouring between East 94th and 95th streets. FaÃ§ade ties will be installed in the five buildings between 1821 and 1829 Second Avenue.
To accommodate work on the 86th Street station, traffic will remain on the west side of Second Avenue between East 85th and 87th streets as workers install Con Ed electrical duct banks. Workers will also be doing manhole work on the northeast corner of East 87th Street, and on the southeast corner of East 86th Street.
A work zone will be closed off to traffic between 84th and 85th streets. Between East 82nd and 84th streets, workers will be constructing two new electric manholes and excavating and installing two new electrical duct banks. Excavation for the replacement of a 48-inch and 12-inch water main is also scheduled.
For work on East Side shaft sites, another work zone will be closed off in the middle of the avenue between East 78th and 79th streets. Workers will excavate test pits and relocate utilities in this area.
Controlled blasting operations between East 72nd and 73rd streets are expected to be finished shortly. Once blasting debris is removed, preparation to install a concrete lining can begin. A work zone will also be cordoned off between East 70th and 72nd streets. Between East 69th and 70th streets, controlled blasting will begin, lasting about five months, and temporary sidewalk sheds will be installed.
Subway work is scheduled from 7 a.m. to 10 p.m., Monday through Friday, and from 10 a.m. to 7 p.m. on Saturdays. Residents with questions can contact Claudia Wilson at 212-792-9716 from 9 a.m. to 5 p.m., Monday through Friday, or contact the Second Avenue subway hotline 24 hours a day, seven days a week, at 646-252-2670.
