Headquarters Expansion

Liberty Mutual Group
Boston, Massachusetts

For over a century, Liberty Mutual has been offering insurance products and services. The Boston based company expanded its office space with the construction of a new 390,000 SF office tower adjacent to the company’s existing headquarters building in downtown Boston. Continuing a decades-long relationship with Liberty Mutual, TG Gallagher installed the plumbing system for the 23-floor high-rise. To improve project flow and safety, the bulk of the work was performed at TG Gallagher’s prefabrication facility.  Trimble Total Station system was used to streamline layout and to remove coring time from the project by sleeving all pipe penetrations and installing bang-its for hangers. The project was designed to achieve LEED Silver certification, and will be nearly 20 percent more energy efficient than a typical large modern office building.
