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 m 2 ) 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 m 2 ) studio to an 8,255-square-foot (766.9 m 2 ), 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 Plan :- Typical Floor Plan Full Floor Penthouse Plan

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 resident s 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.

6. Tower subdivision diagram Lower Floor Program diagram 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 .  T here 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.
