FAST Thermal Bracket^™ Offset Shelf Angle Support

425 Grand Concourse is the largest Passive House development in North America to date

The 26-floor project rises high above the Mott Haven neighborhood of the Bronx and will be a new mixed-use and mixed-income development for low- and moderate-income families.

This is one of many Passive House projects FERO is part of throughout North America. FERO FASTThermal Bracket^™ Offset Shelf Angle Supports are part of the high-efficiency building envelope system providing an energy efficient, thermally-broken shelf angle support system that exceeds the requirements of NYC Energy Conservation Code 2020. 425 Grand Concourse will also surpass the Enterprise Green Communities Criteria and incorporate NYC Active Design Guidelines.

Overview

Greenpoint Landing is a 22-acre master-planned development site located on the Brooklyn waterfront with a view of the Manhattan skyline, bringing a mix of ten residential towers and low-rise buildings, a new public school, and four acres of parkland. The buildings are located on reclaimed industrial use lands, and the brick veneer utilized in the building design provides continuity with the historical neighborhood.

Challenges

For the brick on the Greenpoint Landing F1 tower, the design team was targeting an energy efficient “thermally broken” shelf angle system, and had originally specified a Halfen cast in anchor with knife plate system (Figure 1 and 2). Spacing of the angle knife plate system was specified at 18” on centre for 4,326 linear feet of relieving angle, requiring approximately 2,884 units.

Solutions

In an effort to reduce costs, the contractor suggested a FERO FAST bracket solution (Figure 3) for offsetting the shelf angle.

As FERO became involved at a later stage in this project, the FAST bracket solution needed to accommodate existing wall cavity specifications from the architect, Handel and DiSimone.

FERO was able to accommodate these using custom FAST brackets with a depth of 3-3/16”, slot modified for ¾” bolts and supporting a 4x4x5/16” angle. This project highlights the cost saving proposition of FERO Fast Brackets, as the switch to FAST saved on both material (eliminating more than 1,000 units of the original spec, using only 1,800 FAST Brackets) and labor costs, as the FAST brackets could be quickly installed by a single trade onsite.

Result

FERO’s technical team is available to support designers and contractors in value engineering their projects to reduce costs. On this project, the structural support offered by FAST Brackets allowed for increased spacing and reduced material costs. Additional savings could have been achieved if the anchor channels were not already installed, as the horizontal and vertical adjustability included with FERO Fast Brackets makes such channels redundant. Our team will work with your project specs to ensure costs are minimized through use of the most efficient spacing, anchorage and shelf angle size.
