History
Collapse
The building collapsed while concrete was being poured on the top floor of the building.[3]: 177 Two-thirds of the building was destroyed by a progressive collapse. Approximately 100 men were working in or around the building.[1]
A difficult and dangerous search by rescue workers, involving days of digging, led to the recovery from the building's basement of the bodies of the four workers who died in the collapse.[1][3]: 176–183 The search was postponed for 36 hours while the Boston building commissioner and other experts confirmed the stability of the remaining structure, a delay that angered the coworkers and family members of the missing men.[4]: 3
The four workers killed were:
- Ciriaco DiIorio, 45, laborer, from Roslindale, Boston, Massachusetts[4]: 3
- Michael Papasedero, 27, foreman, from Dedham, Massachusetts[4]: 3
- Daniel Tintindo, 41, welder, from Mansfield, Massachusetts[4]: 3
- James Cingolani, 26, Tintindo's helper, from Quincy, Massachusetts[3]: 176–183 [4]: 3 [5]
Papasedero was last seen after the collapse had begun entering the basement garage, where Tintindo and Cingolani, members of his crew, had been working, to search for them.[3]: 176–183
Cause
Contributory causes of the collapse included lack of quality control and inspections, concrete weakened when left unprotected from cold weather, deficiencies in shoring and reinforcing bars and overly high construction loads on the roof slab. A commission of inquiry concluded that the primary causes of the collapse were lack of shoring and low concrete strength.[1] On July 23, 1972, Controlled Demolition, Inc., imploded the unfinished building after the completion of the recovery effort.[6]
