121 Seaport elevator core tops off
The 17-story concrete elevator core of 121 Seaport has topped off, and a new project banner has been hung along the core. Construction of 121 Seaport's elliptical structural steel frame will follow imminently. 121 Seaport will feature 400,000 square feet of Class A office space above a two-story, 50,000 square foot retail podium. 121 Seaport is targeting LEED Platinum efficiency certification; the building's elliptical design will result in 15 percent energy savings due to less direct solar exposure. The following is a tweet by Skanska showing 121 Seaport's topped-off elevator core:
