2. INTRODUCTION
• A residential skyscraper in New York city.
• Originally proposed to be 1,300 feet (396.2
meters) in 2011, the structure topped out at
1,396 ft (425.5 m).
• Second-tallest building in New York city
after one world trade center and the fifteenth-
tallest building in the world.
• Construction began in 2012 and was completed
on December 23, 2015.
• Apparently the top three floors are a single
penthouse.
• The slim and elegant square tower will ascend
96 storeys and will be constructed using
architectural concrete, steel, and glass.
• In the tradition of New York City’s finest
apartment houses and hotels, residents will
enjoy 30,000 square feet of amenities
including a private restaurant, outdoor
garden for dining and events, spa and fitness
centre with sauna, steam and massage
rooms, 75-foot swimming pool, library,
lounge, billiards room, screening room and
performance venue, children’s playroom,
and boardroom.
432 Park
Avenue was
recognized as a
"Best Tall
Building
Americas"
fianlist in
the 2016
CTBUH Awards
Program.
• 432 Park Avenue distinguishes itself not through extravagance or ornamentation but through
its astonishing slenderness and simplicity of design.
• Exceptionally rational, the tower marks its presence firmly on the Midtown skyline through
its monolithic yet delicate appearance.
• Its extreme aspect ratio, achievable only through innovations in structural design, establishes
an impactful presence for both building occupants and urban dwellers, while offering a pioneering
solution for building tall on a particularly small plot.
•

3. DESIGN
• The design of the structure was conceived
by architect Rafael Viñoly
• Design was inspired by a trash can
designed in 1905 by an Austrian designer.
• Interiors are designed by Deborah
Berke and the firm Bentel & Bentel.
• To support its thin orthogonal frame, the
structure features larger columns at its
base than on the upper floors.
• The tower has eighty-four 8,255-square-
foot (766.9 m2) stories.
Design inspired from trash can
Apartments and amenities :
• The tower's condominium units feature high ceilings, and range from a 351-square-
foot (32.6 m2) studio to an 8,255-square-foot (766.9 m2), six-bedroom, seven-bath
penthouse with a library.
• The building's amenities include 12-foot (3.7 m) golf training facilities and private
dining and screening rooms

4. STRUCTURE SYSTEM
• It is the tallest residential structural concrete building .
• The building consist of two structural tubes.
• Its size and shape are dictated by the unique high-density
requirements of the site and the surrounding area.
• As a result, its height and slenderness push the skyscraper typology to
new extremes with a 1:15 slenderness ratio.
• Simplicity is the defining trait of 432 Park Avenue.
• With a series of large glass windows set in a regular grid of
exposed concrete members, the building offers a clean, rational
exterior, rising out of the ground as a singular, white monolith.
• A flat roof neatly caps the rectangular structure.
Typical Section
• The straight, clean lines of the building’s
façade simultaneously manage to evoke a
modern aesthetic, while also reflecting
Manhattan’s orderly street grid below.
• Each floor incorporates 24 large, square-
shaped windows that add visual weight to the
structure, creating a sense of stability despite
its slender frame.
• The oversized, 9.2-square-meter (99-
square-foot) windows also benefit residents
with ample amounts of light and uncontested
views.
• The gridded window scheme forms
the exoskeleton of the building and
bears structural loads, thus no interior
columns are needed between the
elevator core’s shear walls and the
façade of the building.

5. • Although the tower appears simply as a vertically
extruded rectangular form, there are actually several
two-story “void” levels that help provide stability
against lateral forces.
• As a result, 432 Park Avenue can actually be
considered as six independent buildings stacked on
top of each other, with void levels breaking up the
massing.
• The void levels not only provide an aesthetic
element to the design by adding visually pleasing
disruptions to the façade, but also allow air to pass
through the building.
• This increases lateral stability on the tower in
tandem with a tuned mass damper at the top of the
tower, and also mitigates the “vortex shedding”
phenomenon that develops in buildings with 90-
degree corners.
• Within the voids, the exposed core of the tower –
curvilinear in form – breaks up the angular massing
of the tower, thus adding another element of
protection against vortex shedding.

• The lowest section of the tower is
totally devoted to the amenities
provided exclusively for the residents:
staff accommodations, conference
facilities such as a meeting room and a
screening room, a fully-equipped
restaurant opening to a garden terrace
overlooking 57th Street, health and spa
facilities including a fitness center and
swimming pool, independent storage
spaces, wine cellars, and a sub-grade
parking garage.
• At the base, the building meets the
ground creating a landscaped public
space that extends the feeling of
openness of Park Avenue onto 56th
Street
• All services and delivery accesses are
independently located to the east side
of the tower.
• On 57th Street, a retail volume
maintains its own functional and
architectural identity while
simultaneously aligning with the
geometric discipline of the tower
above.
• Slender, tall, residential and mixed-
use tower rises as a prominent feature
of the New York City skyline design
based on the geometry of a square
stacks seven “independent” buildings
on top of each other to create one of
the city’s tallest structures Public plaza
and retail volume at tower base
maintain their own identities while
referencing the geometry above.

7. BUILDING MATERIALS
• Structural Material – Concrete
Exterior faces consist of white concrete columns and
horizontal spandrel beams with 10’ x 10’ windows.
• Cement – Portland Cement
• The building consists of a concrete core of architectural
concrete surrounding a steel skeleton within and clad with
curtain of glass.
• The exterior faces of the building feature
cast-in-place concrete made with white
Portland cement.
• The decision to use #20 grade 97 rebar for
vertical reinforcement reduced congestion
and was cost productive.
• optimizing the use of Supplementary cementitious materials along with portland cement and
chemical admixtures have enabled very high strengths to be achieved.
• High strength concrete was once described as meeting a 8,000 psi strength threshold
• Different combinations of our slag and cement were tried for optimum performance. These high
strength mixes now have enabled the successful construction.
• Interior finishes include 12.5-foot finished ceilings, solid oak flooring, custom hardware, and
the highest quality natural materials.

8. VERTICAL CIRCULATION
• The team put something called a motion
dampener in the gaps.
• To the untrained eye, these devices look like large
generators, and are able to reduce the force down
even further so that it won't be noticeable.
• Along with separating the building into six blocks,
Viñoly's other method for sway control is a
particular design for the stairs.
• But unlike regular ones, scissor stairs are packed
into a tight core that both saves space, allowing open
floorplans for the apartments, and also creates the
structural conditions necessary for the building to
rise to its ideal height.
• It's one of those innovations that literally makes the
building work.
• In the center of the building we have a square that
is about 30 feet by 30 feet that is housing the
elevator, the stairs, and all the mechanical services
[like] the air, the electricity, the plumbing.
• This core is a box [that is] surrounded by thick
walls that are 30 inches made out of concrete and
with reinforcing inside.
• It's a very robust element that is like the backbone
of the body.
• The Vertical Alignment System is used in
construction of building.
• The Vertical Alignment System frees supertall
construction surveyors from the need to tie to
ground references.
• Building control is independent of ground control,
and surveyors can generate precise coordinates as
needed, compare these to design coordinates, and
correct the building’s vertical alignment
incrementally to keep walls plumb.
“The Vertical Alignment System consists of
consultation, training, installation, and ongoing
management of the data.
• Schindler supplied 11 elevators and 2 escalators, as
well as its The PORT Technology, for this
prestigious project.

9. INTERIORS
• There is a rigid grid to it, and that is what creates
these beautiful volumes and these very elegant
shells.
• There is so much natural light, and at all times of
the day there is something really interesting
happening.
• Fabrics being very tactile and the colors being
things that you would see beyond. at sunset, you see
deep aubergines and these rosy colors.
• Views through those oversize windows to have all
of manhattan unfurl below you in this way is nothing
short of extraordinary.
• the light-filled penthouse features a windowed eat-
in kitchen with marble breakfast bar, oak flooring,
and a master bathroom featuring statuary book-
matched marble floor and walls, and a freestanding
soaking tub.
• 432 park avenue’s amenities and services have
been designed and curated to deliver a luxury
experience on par with the world’s leading five-star
hotels, all in a private residential setting.
