Late last year, Forest City Ratner Companies (FCRC) and Greenland Group Co. (Greenland) completed a definitive agreement for a joint venture to develop Atlantic Yards, a 22-acre residential and commercial real estate project in Brooklyn. The joint venture, which is expected to close in 2014, would cover both phase one and phase two of the project – excluding Barclays Center and the first housing tower, B2 – including infrastructure, a permanent MTA rail yard, a platform above the rail yard and future residential units. The closing of the agreement is subject to necessary regulatory approvals.
“Our original design for the arena had anticipated a green roof as part of our effort to achieve Silver LEED certification,” said MaryAnne Gilmartin, FCRC president and chief executive officer. “While we independently reached that goal, we always hoped to still create a green roof, further improving the environmental footprint of the arena and also making a more direct connection to the sedum covered transit entrance on the plaza.”
Gilmartin explained that in addition to providing a more appealing roof for people visiting and living around the arena, it will also enhance the space for those who will be living in the residential buildings surrounding Barclays Center. The B2 prefabricated steel tower, the first residential building, is currently under construction. At 32 stories, it will be the world’s tallest modular high-rise building when it’s completed next year. Read more about B2 in the current June issue of MSC.
The new roof, supported by a steel structure, will be built above the existing one with an air gap that goes from four ft at the edge of the roof to 10 ft at the highest point. Trays will be arranged to create a “flocking” pattern complementary to the weathering steel exterior and pre-fabricated for streamlined installation. In addition, the arena foundation was built to support this type of load, so minimal reinforcement is required. It is anticipated that three cranes will be needed to install the structure over a period of six months. Roof construction is expected to take approximately nine months.
