It appeared to be under control within an hour.
The school is under construction, the Cambridge Fire Department told WBZ-TV. Work crews were on scene at the time of the blaze but no one was hurt.READ MORE: First Snow Of Season A Hopeful Sign For Businesses That Rely On Winter Weather
Investigators do not know yet how the fire started.
Before the fire, the schools were supposed to be ready in September.
“We’ll have to see how that goes once we speak with all the contractors in the coming days,” said Cambridge Public Schools Superintendent Dr. Jeffrey Young. “Our aim is still to certainly try to get it open but the city is fantastic in managing these projects and I have a lot of confidence in the city manager.”
