Portsmouth, NH North Branch Construction, Inc. has completed the construction of a $4.4 million Student Success Center on the campus of Great Bay Community College. This one-story, 20,000 s/f addition to the existing college includes a gymnasium, administrative offices, a student lounge, a fitness center, and locker rooms. JSA, Inc. provided design for the project, which, despite the tough winter, was completed two weeks ahead of schedule. This is North Branch’s second time working on the GBCC campus – the firm completed major re-roofing and HVAC infrastructure upgrades to the building in 2007.
