New England's tallest residential tower take shape

At 61 stories and 742 feet, One Dalton in the Back Bay will be the third tallest building in Boston. Now under construction, it will house the city's second Four Seasons hotel as well as private residences. It is scheduled to be finished in spring 2019.

GBPCA contractor E.M. Duggan is installing 161,000 feet of plumbing—that's over 30 miles of pipe winding its way through the tower. Bob Jones, Duggan's general foreman, is overseeing the crew.

The massive building is being constructed on a postage stamp-sized lot, so the project poses logistical challenges. The highly efficient project is a model of "lean construction." Read more about One Dalton in The Pipeline.
