This new 12-story mixed-use
development anchors a prominent corner in the Northern Liberties neighborhood of Philadelphia.
A retail space grounds the building and helps to activate the pedestrian
experience while 11 stories of apartments add much-needed height. Amenity
spaces buffer the zone between the retail ground floor and the 329 apartment
units above while 87 parking spaces offer residents secure parking.
The primary structural system is
steel frame with girder slab and a precast concrete floor deck system. The
second level construction is steel frame with a composite concrete deck system.
A mix of brick lines the exterior base of the building with a stucco-like
finish above. A window wall provides visual access to the street level, and
the apartment window system offers views of the city skyline.
Hollow core precast slabs can be
quickly and safely installed on site in variable weather conditions, reducing
the number of workers needed, providing an immediate working platform, and
minimizing disruption to residents during the construction process.
Hollow core offers unparalleled
benefits beneath the exterior. One of the most critical benefits to building
occupants is sound attenuation and privacy. Because the cavities within hollow
core walls and floors dampen sound vibrations, there’s less noise transmission
between spaces than with other types of building materials, such as
conventional wood framing, and less intrusive overhead or next-door sounds.
Used as floor-ceiling assemblies, the sound transmission class rating ranges
from 47 to 57, and the impact insulation class rating starts around 23 for a
plain slab and may be increased to over 70 with the addition of carpeting and
concrete offers passive fire protection, which means it does not rely on
another system or person to take action. Constructed of inorganic elements,
concrete provides a noncombustible environment that curtails fire danger and
confines the damage to other materials into smaller compartments. It also
offers up to a four-hour fire rating and passes a hose-stream pressure test,
minimizing water damage from firefighting if an event were to occur.
