The Problem

Oldcastle Precast, relying on its expertise in precast concrete structures, manufactured 136 precast concrete hollow-core planks for the floors and roof, which were all specially designed to handle the tremendous load of a rooftop greenhouse. Another 70,000-square feet of precast concrete wall panels were supplied for the energy-efficient exterior of the eight-story Forest House building. The exterior walls were cast with a sandblast-type finish with colored concrete to provide a visually appealing look.

The Design

In addition to the housing structure, Oldcastle Stormwater manufactured and installed a StormCapture water harvesting system. The system included special StormCapture retention modules that hold about 16,000 gallons of captured stormwater each, and an equipment package that treats the captured water, making it available for irrigation to the rooftop hydroponic greenhouse.

The Solution

This is the fifth precast concrete building the developer Blue Sea Development and Oldcastle Precast have collaborated on over the past 10 years. Oldcastle Precast worked closely with Blue Sea and ABS Architects, the project architect, during the design phase to develop a cost-effective solution that met all of the project’s many requirements.
The development team consisted of Blue Sea Development, Blue Sea Construction, ABS Architects and T.Y. Lyn International Group, a global engineering firm. The team was selected due to its storied history of affordable public housing that is both attractive and sustainable.
