East Side Access

The East Side Access is a $10 billion MTA project which will connect the Long Island Rail Road to Grand Central Terminal in Manhattan. The project involves several major construction initiatives: excavating and constructing a new rail tunnel extending from Sunnyside, Queens into Manhattan’s Grand Central Terminal, and constructing mined caverns under the existing Grand Central Terminal for the new passenger rail station.

Tectonic is providing special inspection and materials testing for all soils, cast-in-place concrete, asphalt, structural steel, precast concrete, shotcrete, earth anchors, blast monitoring, pile driving, grouting and underpinning for three separate contracts involving tunneling, site work and mined caverns. It is also providing geotechnical engineering services for pile driving, earth anchors, blast monitoring and underpinning.

Tectonic also provided surveying and structural engineering services for the design of an elevated conveyor system to transport excavated material from the new MTA subway tunnel to a transfer station.
