Welding sets construction material on fire in new Fenway building under construction

Boston firefighters responded to 421 Park Dr., now under construction as a 13-story addition to the former Landmark Center, for a fire that started by welding and construction debris on the fourth floor but spread several floors upward, around 5:10 p.m.

The fire was declared out about 25 minutes later.

The ground floor of the building, being developer by Samuels and Associates, is slated to become a new Star Market, to replace the one on the other side of Boylston Street.
