The company that poured the high-security concrete superstructure for 1 World Trade Center says that it’s struggling to stay afloat after the Port Authority of New York and New Jersey refused to pay $87 million for services rendered, the New York Daily News reported yesterday. A business entity tied to Collavino Construction Company, one of the main contractors on the Lower Manhattan tower, has filed for chapter 11 bankruptcy protection, claiming that it can’t afford to pay its suppliers until it’s been paid. The Port Authority tapped Collavino, a Canadian company with offices in New Jersey, in 2007 to construct the 105-floor concrete superstructure for the iconic building, according to the bankruptcy filing. The specially reinforced concrete it poured was designed to protect the above-ground portion of the building from a street-level blast.
