Architecture:
The renovated building's façade is beige brick masonry; its style is typical to buildings from the turn of the century. The new construction is zinc metal paneling, alternating with full height glazing. An example of this paneling is shown below on a recently constructed building. The new building “wraps” the old one, since it adds space to the east portion of floors 1-5, and creates two new floors, the 6th and 7th floors. The sum appearance seems to represent modern design merging with old.
Zoning:
The site was originally industrial, but was rezoned for residential / commercial.
This residential / commercial area of Hoboken was expanded during the 90’s,
and the industrial zone was pushed farther north. 14th street is on the
edge of this border, with a yet to be utilized green belt between the 14th
street buildings and the industrial zone.
Electrical:
120/208 Voltage is supplied to all residences, for lighting and receptacles. The building is supported by an electrical room supplying 1200 A to the building
Lighting:
Condos are equipped with incandescent/compact fluorescent ceiling fixtures
in all rooms
The retail space is provided with bare fluorescent fixtures.
Mechanical:
Condo heating is met by hot water fin tube radiators below the windows. The ventilation requirements are met by supplying fresh air through the central air units in each condo. The air is drawn from two roof top units which temper the air to 70 deg F.
Retail heating is provided by resistive radiator units.
Two 1400 MBH boilers in the basement supply these heating loads.
Condo cooling is provided by one or two fan coil units in each apartment and supplied through steel rectangular ducts to each room. Fresh air is drawn from the rooftop units to supply the fan coil units. The roof top units cool the air to 60 degrees, before fan coil units cool the mixed air to supply air temperature.
Two cooling towers on the roof and two electric scroll chillers in the basement supply the coiling coils to meet these loads.
The plumbing is designed to NJ code
Structural:
The renovated, 5 story original building is a concrete, cast iron, and steel structure. Circular, cast iron columns are spaced at 14 and 23 feet with diameters ranging from 12” to 5”, and encased in concrete. The floors are supported by concrete beams and girders, and a 5” formed concrete slab. The tension elements of the concrete beams and girders are steel wide flanges, sunk into each beam and girder, shown below. The beams’ wide flanges are supported by shelves cast integrally with the column. The external walls have a similar construction, but fewer columns and longer spans. The foundation is comprised of a 7’x7’ stacked brick pier under each column, with a 10’x 10’ and 2’ deep footing below each pier, integral with the slab. The top two floors (4&5th) of this old section will be internally replaced to support the additional 6th and 7th floors, and the lower columns will be reinforced to be made more rigid and support the additional load.
The new construction is steel frame. The first two levels are a moment frame to create clear spaces for retail and mezzanine, and the higher floors and top two floors are a braced frame construction. The stair wells and elevator shafts will be steel frame added in the renovated building. The foundation will be concrete footings with minipiles. Floor construction is steel deck with poured concrete slab.
