Thanks to a heated (65°) area within a barricaded zone, which segregated construction work at Murray Hill Station throughout the winter, the concrete pour for the eastbound and westbound elevator shafts was successful. The eastbound shaft is being backfilled, while the westbound shaft has already been backfilled, replacing the excavated soil.
The westbound machine room is now being installed, and structural “micropiles” have been installed. The machine room is an actual room housing the machinery and electrical controls that operate an elevator; the micropile is a deep foundation element – constructed using high-strength, small-diameter steel casing and/or threaded bar – which carries the load. In May two micropiles will be installed in the eastbound elevator shaft.
