White Mountains Capital has relocated from One Beacon St. to a new office at 265 Franklin St. in Boston, according to Newton-based owners representative firm Diversified Project Management (DPM).

"As part of our ongoing partnership with OneBeacon Insurance, we are pleased to extend our involvement with them through the White Mountains relocation," says Tony Zulkeski, project executive at DPM. "They are a leader in the insurance industry and we are proud to continue to be a part of their team."  

DPM managed the bidding and selection of the general contractor as well as the coordination of all vendors during various phases of the project which included programming, pre-construction, construction administration and relocation management. 

"The construction and overall project was on time and within budget," said Shirley Lampron, director of accounting policy for White Mountains Capital.  DPM made the move to our new location a smooth transition for the entire staff and we were up and running at the start of business on Monday."

In the past, DPM has managed similar relocation projects for Aviva Life Insurance, New York Life Investment Management, GenRe and Summit Partners, the company said.
