Edgewater, New Jersey
The St. Moritz is a reinforced cast-in-place concrete high-rise residential structure located at the foot of the palisades in Edgewater, New Jersey. It consists of 19 stories of apartments above grade (280,000 gross square feet) and 4 levels of parking below grade (120,000 gross square feet).
The site was steep and rocky and posed a challenge to the construction of a high-rise building. The excavation of the loose rock to sound material ultimately resulted in footing elevations varying as much as 40 feet. Concrete columns and flat-plate floor slabs comprise the structure above. Concrete foundation walls surround the structure below grade.
Reinforced cast-in-place concrete construction was chosen for this project because of its many benefits. Lead time is reduced as foundations may be started as soon as the design is completed without the delay imposed by the fabrication of structural steel. The flexibility of concrete, structurally and architecturally, is also an advantage. Footing elevations hence column lengths could easily be adjusted for field conditions by constructing from the formwork to suit.
Floor-to-floor heights are minimized through the use on concrete and flat-plate design resulting in a more efficient building. Floor vibration and sound transmission in reinforced concrete structures is minimal. Building sway is also reduced; important in high-rise construction. Concrete is also naturally fire-resistant and durable, saving on fireproofing and providing a serviceable structure for many years to come.
