"An investigation by the agency’s Office of Inspector General found Metro had “exceedingly stringent” requirements for its rail-car carpet, stretching back decades, that were probably written to favor one supplier.
In fact, the “100 percent pure virgin wool” carpet was made to specifications no longer in use in the industry, the inspector general said, resulting in the “appearance of favoritism” toward the contractor.
The recently concluded investigation found that Metro’s standards for its carpeting were unchanged for two decades and that no other vendor could plausibly compete for the contract.
Moreover, the carpet lacked a required coating to prevent fungus and mildew, Metro Inspector General Geoffrey Cherrington said — although it did meet standards for being fire-resistant and mothproof.
Further investigation found the carpet’s compliance testing was not being performed by an independent facility, as Metro requires, but by a laboratory with ties to the carpet manufacturer.
“The director of the lab used by the vendor is married to the Chief Financial Officer of the company that provided the vendor a line of credit” for the carpet order, according to a synopsis of the investigation included in a report to the Metro board."
