The New York City area's main transit agency, the Metropolitan Transportation Authority, has operated during most of 2019 under strict new emergency debarment rules for contractors. They were put in place quietly earlier in the year and allow MTA to debar a firm if a construction project runs more than 10% late or 10% over budget—no matter what the cause.
In other words, the MTA, which is controlled by Gov. Andrew Cuomo (D), is effectively giving itself the option of eliminating change orders as part of a program to get tough with its engineers, contractors and vendors.
