The subcontractor responsible for maintaining a standpipe that failed during a seven-alarm fire in the former Deutsche Bank building that killed two firefighters will likely be fired from the demolition project.

The subcontractor, John Galt Corporation, had been hired to dismantle the condemned building, which was contaminated with asbestos and other toxins as a result of the September 11, 2001 terrorist attacks on World Trade Center towers across the street. The general contractor, Bovis Lend Lease, sent the subcontractor a “notice of default” yesterday, a precursor to termination, noting the company’s “inability to live up to the terms of its contract with respect to site supervision, maintenance, and project safety at the 130 Liberty Street site.”

The broken standpipe lay detached in the basement during Saturday’s fire, leaving firefighters with no water for their hoses when they arrived on the building’s top floors, where the fire was raging. Building inspectors had visited the structure regularly, including the day before the fire, but were only charged with checking the condition of the standpipe near the floors being dismantled.

The New York City Fire Department confirmed yesterday that it had not run a thorough check of the building’s water supply since 2005.

Nor did it have an overall plan when it sent hundreds of firefighters into the burning high rise, which was full of ground zero toxins, according to a report about the ongoing investigation by fire marshals released yesterday.

In the report, fire officials laid out in detail missed opportunities that may have helped save the lives of two firefighters who died when they ran out of air trying to escape a maze of construction debris and blocked stairways.

Firefighters from the firehouse next door at one time visited the Deutsche Bank building every two weeks to check on the conditions inside. They suddenly stopped going in March 2006 and never went back, according to the report — even after a steel pipe from the building fell through their roof in June.

The fire department also had not done a full test run of the standpipe since 1996, even after an anonymous call suggested that the standpipe had been disabled in 2004. Instead, the FDNY relied on assurances that it was operational, including an affidavit from a plumber, made by the building’s owner, the Lower Manhattan Development Corporation.

According to the fire marshal’s report, the last time fire officials visited the building to conduct a “familiarization visit” was on April 6, 2005. On that date, representatives from Manhattan Borough Command, Division 1, Battalion 1, Engine 10, and Ladder 10 walked through the site.

By August 18, the day of the fire, the building would have been radically different after workers had hung sheeting throughout the building, boarded up stairwells, and gradually taken apart the walls, ceilings, and floors.

The contractors were responsible for keeping the fire and buildings departments informed about conditions at the site. According to an emergency preparedness plan, Bovis Lend Lease and John Galt Corporation were to hold regular meetings about emergency planning to which the FDNY and buildings department were supposed to be invited. The contractors also were supposed to provide city agencies with drawings of the building and update them as it was dismantled from the top down.

“We have not been invited by any meeting organized by the contractor,” a spokeswoman for the buildings department, Kate Lindquist, said.

“These are all questions that will be covered by the investigation. The investigation should be allowed to run its course,” a spokesman for the LMDC, Errol Cockfield, said yesterday in response to questions about the emergency plan.

John Galt Corporation could not be reached for comment yesterday.
