A construction worker from Standish died after an excavator overturned at a worksite in Gray on Monday.

John Woodman, 61, was a longtime employee at Shaw Brothers Construction, according to the Cumberland County Sheriff’s Office. The accident is being investigated by the sheriff’s office and the U.S. Occupational Safety and Health Administration.

Crews from the construction company as well as Unitil were working on a petroleum pipeline in a wooded area behind 78 Bull Run Road in Gray when the accident occurred Monday afternoon.

Woodman was driving an excavator on a steep grade when the machine overturned, the sheriff’s office said. He died at the scene.

Woodman worked for Shaw Brothers Construction for more than 30 years, the company said in a written statement Tuesday.

“John was a dedicated machine operator and, more importantly, a remarkable person who earned the respect and friendship of those around him,” Shaw Brothers stated. “This is a significant loss for our company and community, and our thoughts and prayers are with his family during this difficult time.”

The company said it is ensuring counseling services are available to any employees who need it.

Authorities say the excavator suffered minor damage and alcohol did not appear to be a factor in the crash.

Woodman’s cause of death will be determined by the Office of Chief Medical Examiner.

An OSHA spokesperson confirmed Tuesday that the agency had begun an investigation but would not be able to share more information until it is completed. OSHA has six months to complete the investigation, the spokesperson added.
