Project Overview:

Renovations to Madison Yard, located under the Grand Central Terminal in Manhattan are vital to the East Side Access Tunnel Project. Several tracks, crash walls, commissary areas were demolished and reconstructed to facilitate use by the LIRR.

Distinct Engineering Solutions, Inc. (DESI) has been retained by the Gramercy Group Inc. (GGI), to provide Health & Safety, Engineering and Construction Inspection Support including an evaluation of subsurface soil and rock quality.

DESI developed site specific Construction Safety & Health Plan and Safe Work Plans for various tasks undertaken by Gramercy.
