In April 2008, the MTA awarded Dragados/Judlau another contract. The $506 million contract was for excavating caverns for the three-level platform structures, mezzanine, escalators, passageways, and track crossovers. The MTA gave Gramercy Group Inc. the $38.9 million contract to reconfigure part of Madison Yard in March 2009. In September 2009, the MTA awarded Yonkers Contracting Company a $40.8 million contract to demolish a building at 47 East 44th Street and construct a ventilation plant & concourse entrance on the building site, along with constructing a station entrance at an existing office tower at 245 Park Avenue (at East 46th Street). Smaller contracts for electrical installations and structural repairs were also awarded in 2008. In 2010, the New York City Business Integrity Commission found that a subcontractor for the East Side Access project was involved with an organized crime family. The subcontractor, who had been hired to haul away the dirt from the excavation process, was replaced.
