A construction worker died on the job Thursday after being struck by a vehicle outside a home on Sunset Avenue in Concord.

Brian Sullivan, 45, of Pittsfield suffered life-threatening injuries and was taken by ambulance to Concord Hospital, where he later died, according to a statement from Concord police Lt. Tim O’Malley.

The incident occurred on private property at 12 Sunset Ave. and was reported about 3:30 p.m.

Sullivan was employed with William Young Excavation and Site Work of Bow, which specializes in paving, excavating, sealcoating and stamped asphalt. The Concord homeowner hired the company to construct a driveway, O’Malley said.

O’Malley said the Concord Police Department’s initial investigation found that Sullivan was pinned between two construction vehicles, one of which was stationary and the second of which backed up into him.

William Young Excavation declined to comment Friday about the incident but offered condolences to Sullivan’s family.

Police are not identifying the driver of the vehicle that struck Sullivan, citing an ongoing investigation. O’Malley said the driver’s name will be released once police determine whether they will file criminal charges.

The Sunset Avenue neighborhood was quiet Friday afternoon except for the occasional sounds made by contractors renovating the home next door to where the incident occurred. Peter Mellow, who will soon be moving into the newly refurbished home, said he was working in an upstairs room Thursday afternoon when he heard commotion outside.

Mellow said he heard someone scream. When he went next door to check things out, he said he heard a construction driver there say, “I think I killed him. I think I killed him.”

Mellow said he then saw a man lying behind a dump truck.

William Young Excavation had just started working at 12 Sunset Ave., on Thursday, he said.

The home has a paved driveway leading to a one-car garage. To the paved driveway’s left is a path of dirt and rock of similar width where construction crews were working Thursday. No one was on site Friday afternoon.

The Occupational Safety and Health Administration opened an investigation into the incident after responding to the home. The investigation will determine whether there were any violations of workplace safety standards in connection with Sullivan’s death, according to OSHA spokesman James Lally.

Lally said Friday it’s too early to say when the investigation will be complete.

Police are asking anyone who witnessed the incident to contact them at 225-8600 or the Concord Regional Crimeline at 226-3100.
