SGH designed the two-story, 60,000 sq ft structure for the addition, which is integrated with the existing building.  Highlights of our design include the following:

• Interior structural steel columns and beams supported on shallow concrete spread and strip footings
• Perimeter load-bearing steel stud walls, which provide a clean profile to the exterior walls without column enclosures that impact the interior layout
• Hollow core concrete floor plank, which can be erected relatively quickly, provides the required fire separation between floors, and helps to dampen  noise transmission
• Prefabricated wood trusses that create the sloped roof profile and can erected in less time that conventional stick framing
• Concrete masonry for elevator and stair shafts that provide the necessary fire separation and serve as part of the lateral-load-resisting system
