- Number of Stories: 15 and 4 below-grade
- Use/Occupancy: Mixed commercial and residential
- Window wall, exterior-insulated brick veneer, and cultured stone.
- “Waterfall”— each elevation includes a bay pop out of by-pass window wall, continuous through several; 10 floors.
- Four levels of below-grade parking, and a very active, high water table made site dewatering and waterproofing a real challenge. Required four floors above ground to not “float”. Concrete floors had to be poured to four levels above-grade before dewatering could be turned off to keep building from being pushed up by water pressure.
- Taller floor heights at upper levels resulted in very difficult air barrier transitions due to suspended structural steel framing penetrations.
- Complex detailing of saddle flashing at top of waterfall step back over rainscreen cultured stone and penthouse deck with living space below.
