Green line service between Gare du Nord and the government center resumed on Saturday, two weeks after a deadly car park collapse sent tons of debris onto the streets above the tunnels.
Part of the Government Center parking lot collapsed on Saturday March 26, killing Peter Monsini, 51, of South Easton, and sending another person to hospital.
Immediately after the collapse, roads were closed and Orange and Green Line service was replaced with shuttles while investigators determined the safety of the structure. When Orange Line service resumed several days later, these shuttles were discontinued and passengers were directed to the Orange Line.
Trains have been and will continue to bypass Haymarket station on both lines until crews can complete repairs to the standpipe system, which has been damaged by the debris.
MBTA officials said more than 100 tons of debris had been removed directly above the Green Line and structural engineers had carefully assessed the tunnels to ensure their safety. Engineers will continue to monitor the tunnel for the immediate future.
Days after the partial collapse of the Boston Government Center parking lot, service on the Orange Line has largely returned to normal, but Green Line service in the area remains suspended. The shuttle service on this section of the Green Line is interrupted from Wednesday. Passengers are encouraged to use the orange line instead.
Parking lot collapse details
Part of the Government Center garage collapsed after a concrete slab on the ninth floor collapsed. The demolition is part of the $1.5 billion Bullfinch redevelopment project, construction firm John Moriarty & Associates said in a statement. The finished project should include a parking garage surrounded by office and apartment buildings.
Boston Fire Marshal Jack Dempsey told reporters that Monsini was completing demolition work in a construction vehicle that fell over the side of the garage when the structure collapsed around 5:40 p.m. Saturday.
The vehicle fell eight or nine stories with a large amount of debris. Monsini was found under a pile of rubble and pronounced dead at the scene by authorities, Dempsey said. A second person was taken to an area hospital after the accident.
The incident was the first fatal construction accident of the year in Massachusetts.
Peter Monsini was completing demolition work in a construction vehicle that rolled over the side of a Boston parking lot when the structure collapsed. Now an investigation is underway.
Emergency teams were called to the same site 2 months earlier
NBC10 Boston investigators uncovered a call for help at the same construction site months before the deadly collapse. Footage of the construction area from January 14 shows a major fire rescue response.
According to scanner audio from that night, firefighters were called to a “dangerous and unstable construction site involving a crane”. First responders originally planned to stage a rescue operation on Surface Road at New Chardon Street, but later determined this would not be necessary.
According to a police report, emergency crews responded after a burst water main caused a leak at the site. The report said a fire department detail was worried that a crane at the construction site would fall due to the water leak.
“Officers observed water coming from the construction site on New Chardon Street,” the report said.
Boston Water and Sewer responded to the leak and all streets within 300 feet of the construction site were closed to pedestrians and vehicles for safety reasons. The Boston Fire Department and Bay Crane ultimately determined the crane to be stable. The report said the site would be closed and the crane watched from the right until an engineer could inspect it. What this engineer found was not included in the report.
Investigation into car park collapse underway
A full-scale investigation into the collapse is currently being conducted by Boston police, the office of Suffolk District Attorney Kevin Hayden, and the Occupational Safety and Health Administration. Hayden said Monday his office was not ruling out the possibility of criminal charges.
“That some degree of negligence turns into criminality, that’s what our investigation will focus on,” Hayden said.
OSHA will play the lead role in the investigation, but local, state and federal authorities will also be involved, the district attorney’s office said.
Boston Mayor Michelle Wu said the city would do “whatever it takes” to find out what happened.
