• Architecture: 110 Third Avenue serves as a great addition to the New York skyline with twenty-one stories of residential condominiums. The exterior façade is reminiscent of the repeating patterns found quite often in 1960’s post-modern architecture. The spiraling balconies and tapered neck of the building alter the Roheian approach to box skyscrapers slightly to adjust for more modern tastes. The prime downtown location in the heart of Manhattan allows tenants to experience the very best of the city that never sleeps in their own private haven. First floor apartments offer 2 bedrooms, 2.5 baths with living room, kitchen and access to a private recreation room downstairs complete with a private terrace. All tenants have access to an in-house gym located on the cellar level. Floors 2 through 15 have four or five units per floor, and units feature either one or two bedrooms plus bathroom(s), living room, and kitchen. Floors 16 through 21 have only three units with three bedrooms, 2.5 baths, living room, and kitchen.

• Model Code: Building Code of the City of New York, including latest amendments (“N.Y.C. Code”)

• Zoning: 110 Third Avenue occupies a residentially zoned site that previously consisted of a parking lot, 1 story residential building, 3 story residential building, and a 4 story residential building

• Historical Requirements: None

• Building Envelope: The exterior walls of 110 Third Ave. consist of a “window wall”system. This system is fixed window units fabricated with flush aluminum panels finished to match the window wall that rests on the slab. Surrounding the windows are glazed aluminum window wall framing. The window units themselves consist of a 1/4” thick nominal aluminum composite panel affixed to the exterior face window-wall unit with conceded fasteners and/or adhesives finished to match the window-wall. Also present is an insulating spandrel panel. On the North and East sides of the building are balconies from floors 8 through 16 and 16 through 21, respectively. Each balcony is cantilevered 5’ from the building face. The roof is concrete slab supporting mechanical equipment, but it also hosts several private terraces and a common terrace for occupants. The roof itself is composed of a layer of fluid applied roofing membrane, drainage panels, 4” polystyrene, adjustable paver pedestals, topped with a layer of precast concrete pavers. Surrounding the living spaces is a 4’-0” high perimeter parapet planter all around the roof.

Part 2

Construction: Has not begun yet. Set to begin in November. Will take approximately six months to construct.

Structural:

The structural system of 110 Third Avenue is predominantly precast concrete. Most floors have 8” CIP slab, but beginning with floor 15 the slab increases to as much as 24” to support cantilevered portions of the building and mechanical equipment on the roof. All slabs and columns have f’c= 5000 psi. Loads are carried from the two-way slab system to concrete columns ranging from 12x12 to 40x12. The columns are continuous throughout the height of the building except for a few columns that terminate at floor 16 due to a setback in the building perimeter, and a few columns that originate on the drawings at floor 11 due to the reduction of the elevator core to column-sized portions. Footings range from 4’6” square up to 15’ x 9’6”. The only beams present in the structure are in the basement level and are grade beams extending from perimeter East-face and West-Face footings to the outside wall. Shear walls extend throughout the height of the building and are located mostly on the North and South sides of the building. The roof is a flat slab system that is drained by roof drains nested under pavers. Supporting columns are recessed from the façade on average 10”, and therefore allow the designer to use non-bearing prefabricated panels.

Electrical:

Electrical service is brought into 110 Third Avenue by Con-Edison service 120/208V 3 Phase 4 wire distributed to two switchboards located on the cellar level. Switchboard 1 services the residential portions of the building, retail space, and gym area with meters every third floor. Switchboard 2 powers utilities such as the sprinkler system, fire pumps and elevators. Circuit wire sizes are most commonly 2 #12-3/4”C, and branch circuit breakers are most commonly 1 pole, 20 Amp. All circuits and feeders have a full size insulated green ground conductors and are connected to the ground bus in their respective panels. Minimum size conductor and conduit is #12 THHN CU, ¾”C (EMT). All mounted wall switches, dimmer, etc., are at 4’0” A.F.F. to center line of devices. Receptacles are mounted at 15” A.F.F. The electronic ballasts meet or exceed both the minimum ballast efficiency factor (B.E.F.) as specified by Con-Edison and total harmonic distortion (T.H.D.) requirement or 20% or less. All fluorescent light fixtures have energy saving lamps and are equipped with electronic energy saving ballasts.

Lighting: Has not been designed yet. Will be designed in 1.5 weeks.

Mechanical:

Mechanical system has only been preliminarily designed. 100% construction documents will be completed in 1.5 weeks.

Heat: Boiler size in BTUs. What it’s fired by (gas, elect., oil). System capacity for cooling in tons. A 2-cell cooling tower is located on the roof serving water-source heat pumps at 990 CPM per tower with 330 tons capacity per tower. CFM total is 48680. Stairwells are heated by individual electric heaters mounted to underside of landing fully recessed. Manufacturer in size. Delivery system (VAV and reheat).

Living rooms feature baseboard water heating as per hot water fin runtal RF—2 at 600 BTU/hr @180 F. Bedrooms feature individual heating recirculation units.

Fire Protection: The system is a sprinkler alarm system per NYC building code and includes elevator recall and fan shutdown. Ducts feature smoke detector wired to the central alarm system. Other system features have not been designed yet. Pull station locations are yet to be determined.

Transportation: The core of 110 Third Avenue features all transportation systems including two elevators servicing all floors. The central stair case abuts the two elevator shafts to the north, but additional stairs connecting individual apartments to private terraces and service staircases exist on the cellar level. Also featured is a refuse room located southeast of the elevator shafts that transports waste to exit the building.

Telecommunications:

110 Third Avenue features a telephone room located in the basement. Each apartment has approximately nine combination voice/data CAT-E cable/ TV coaxial RG-6 cable outlets. There are typically two combination outlets found in each bedroom, and two or three found in each living room. Each kitchen has a voice CAT-5E cable for a wall phone. Also, located in all apartment hall closets is the apartment NID panel.

Plumbing:

All connections made to 110 Third Avenue come directly from Third Avenue as opposed to 13th or 14th streets which surround the site. The building has full sewer, gas, and water services. Sewage and water lines, on the first floor, run through the center of the building to retail spaces and the two luxury apartments located in the rear. Each subsequently higher floor matches the points of connection and ties to lower floors with vertical pipes located in the walls next to the bathrooms and kitchens. The cellar possesses a domestic water booster pump, DCVA, and meter for the entire building. Present on the first floor are three none-freeze wall hydrants. Roof drains are connected all the way to the basement level where there are three sump pumps. One sump pump services the basement level while the other two are elevator sump pumps. Gas is provided by Con-Edison through a 4” line connected on the basement level extending vertically to stoves on each floor.
