150-590: The Chanin Building ( / ˈ tʃ æ n ɪ n / CHAN -in ), also known as 122 East 42nd Street , is a 56-story office skyscraper in Midtown Manhattan in New York City . It is on the southwest corner of 42nd Street and Lexington Avenue , near Grand Central Terminal to the north and adjacent to 110 East 42nd Street to the west. The building is named for Irwin S. Chanin , its developer. The structure

300-459: A Buttressed core . Trussed tube and X-bracing: Elevation (architecture) Architectural drawings are made according to a set of conventions , which include particular views ( floor plan , section etc.), sheet sizes, units of measurement and scales, annotation and cross referencing. Historically, drawings were made in ink on paper or similar material, and any copies required had to be laboriously made by hand. The twentieth century saw

450-424: A cutaway view parts of the exterior are omitted to show the interior, or details of internal construction. Although common in technical illustration, including many building products and systems, the cutaway is in fact little-used in architectural drawing. Architectural drawings are produced for a specific purpose, and can be classified accordingly. Several elements are often included on the same sheet, for example

600-400: A stencil , or a combination of the two. Ink lines were drawn with a ruling pen , a relatively sophisticated device similar to a dip-in pen, but with adjustable line width, capable of producing a very fine controlled line width. Ink pens had to be dipped into ink frequently. Draftsmen worked standing up, keeping the ink on a separate table to avoid spilling ink on the drawing. Developments in

750-458: A synonym for façade, so the "north elevation" is the north-facing wall of the building. A cross section , also simply called a section, represents a vertical plane cut through the object, in the same way as a floor plan is a horizontal section viewed from the top. In the section view, everything cut by the section plane is shown as a bold line, often with a solid fill to show objects that are cut through, and anything seen beyond generally shown in

900-473: A view camera or a perspective control lens is used to eliminate the third vanishing point, so that all the verticals are vertical on the photograph, as with the perspective convention. This can also be done by digital manipulation of a photograph taken with a standard lens. Aerial perspective is a technique in painting, for indicating distance by approximating the effect of the atmosphere on distant objects. In daylight, as an ordinary object gets further from

1050-554: A basis for their working drawings, to establish exact dimensions for the construction work. Surveys are usually measured and drawn up by specialist land surveyors . Historically, architects have made record drawings in order to understand and emulate the great architecture known to them. In the Renaissance, architects from all over Europe studied and recorded the remains of the Roman and Greek civilizations, and used these influences to develop

1200-423: A building construction project: these will include not only architect's drawings, but structural and other engineering drawings as well. Working drawings logically subdivide into location, assembly and component drawings. Formerly, working drawings would typically combine plans, sections, elevations and some details to provide a complete explanation of a building on one sheet. That was possible because little detail

1350-403: A building or group of buildings. A site plan shows property boundaries and means of access to the site, and nearby structures if they are relevant to the design. For a development on an urban site, the site plan may need to show adjoining streets to demonstrate how the design fits into the urban fabric. Within the site boundary, the site plan gives an overview of the entire scope of work. It shows

1500-416: A building proposal prior to detailed design: drawing up a site plan is a tool for deciding both the site layout and the size and orientation of proposed new buildings. A site plan is used to verify that a proposal complies with local development codes, including restrictions on historical sites. In this context the site plan forms part of a legal agreement, and there may be a requirement for it to be drawn up by

1650-493: A building trade convention's judges referred to as "America's finest bathroom". This bathroom was decorated in orange and white, and it contained etched-glass shower panels and brass fixtures. Irwin Chanin's 52nd-story offices were accessed through a set of wrought-iron gates designed by Chambellan. The gates are decorated with symbols of "the spirit of modern industry", such as cog wheels and coins. There were bronze vector grilles within

1800-414: A building. For example, the construction of a sash window would be left to the carpenter, who would fully understand what was required, but unique decorative details of the façade would be drawn up in detail. In contrast, modern buildings need to be fully detailed because of the proliferation of different products, methods and possible solutions. Perspective in drawing is an approximate representation on

1950-455: A bulky square 45-story tower designed by Rouse & Goldstone . The brothers still had a reputation for being involved mostly in the theater industry. According to one author, when the Chanins started clearing the site in 1927, many members of the general public could not tell "whether the Chanins were builders or [...] theater-owners who had taken up building as a sideline." The warehouse itself

2100-537: A city consisting entirely of high-rise housing is the 16th-century city of Shibam in Yemen . Shibam was made up of over 500 tower houses, each one rising 5 to 11 stories high, with each floor being an apartment occupied by a single family. The city was built in this way in order to protect it from Bedouin attacks. Shibam still has the tallest mudbrick buildings in the world, with many of them over 30 m (98 ft) high. An early modern example of high-rise housing

2250-461: A convenient diagram but as a formal presentation technique, adopted in particular by the Modern Movement . Axonometric drawings feature prominently in the influential 1970's drawings of Michael Graves , James Stirling and others, using not only straightforward views but worms-eye view, unusually and exaggerated rotations of the plan, and exploded elements. Detail drawings show a small part of

2400-410: A different scale is required for different axes , and again this can be calculated but in practice was often simply estimated by eye. Traditional drafting techniques used 30–60 and 45 degree set squares , and that determined the angles used in these views. Once the adjustable square became common those limitations were lifted. The axonometric gained in popularity in the twentieth century, not just as

2550-498: A dominant landmark in the midtown skyline upon its opening, the building had an open-air observation deck on the 54th floor. It was one of three open-air observatories in the city following World War II , the others being at 30 Rockefeller Plaza and at the Empire State Building , though there had been several other observation decks in the city prior to the war. The Chanin Building only charged 25 cents for admission, since it

2700-445: A flat surface of an image as it is perceived by the eye. The key concepts here are: The basic categorization of artificial perspective is by the number of vanishing points: The normal convention in architectural perspective is to use two-point perspective, with all the verticals drawn as verticals on the page. Three-point perspective gives a casual, photographic snapshot effect. In professional architectural photography , conversely,

2850-417: A licensed professional: architect, engineer, landscape architect or land surveyor. An elevation is a view of a building seen from one side, a flat representation of one façade . This is the most common view used to describe the external appearance of a building. Each elevation is labelled in relation to the compass direction it faces, e.g. looking toward the north you would be seeing the southern elevation of

3000-733: A more classical approach came back to global skyscraper design, that remains popular today. Examples are the Wells Fargo Center , NBC Tower , Parkview Square , 30 Park Place , the Messeturm , the iconic Petronas Towers and Jin Mao Tower . Other contemporary styles and movements in skyscraper design include organic , sustainable , neo-futurist , structuralist , high-tech , deconstructivist , blob , digital , streamline , novelty , critical regionalist , vernacular , Neo Art Deco and neohistorist , also known as revivalist . 3 September

3150-477: A napkin. Initial thoughts are important, even if they have to be discarded along the way, because they provide the central idea around which the design can develop. Although a sketch is inaccurate, it is disposable and allows for freedom of thought, for trying different ideas quickly. Choice becomes sharply reduced once the design is committed to a scale drawing, and the sketch stage is almost always essential. Diagrams are mainly used to resolve practical matters. In

3300-399: A particularly small surface area of what are conventionally thought of as walls. Because the walls are not load-bearing most skyscrapers are characterized by surface areas of windows made possible by the concept of steel frame and curtain wall. However, skyscrapers can also have curtain walls that mimic conventional walls and have a small surface area of windows. The concept of a skyscraper is

3450-420: A product of the industrialized age , made possible by cheap fossil fuel derived energy and industrially refined raw materials such as steel and concrete . The construction of skyscrapers was enabled by steel frame construction that surpassed brick and mortar construction starting at the end of the 19th century and finally surpassing it in the 20th century together with reinforced concrete construction as

3600-454: A proto-skyscraper, or to New York's seven-floor Equitable Life Building , built in 1870. Steel skeleton construction has allowed for today's supertall skyscrapers now being built worldwide. The nomination of one structure versus another being the first skyscraper, and why, depends on what factors are stressed. The structural definition of the word skyscraper was refined later by architectural historians, based on engineering developments of

3750-412: A proud and soaring thing, rising in sheer exaltation that from bottom to top it is a unit without a single dissenting line. Some structural engineers define a high-rise as any vertical construction for which wind is a more significant load factor than earthquake or weight. Note that this criterion fits not only high-rises but some other tall structures, such as towers . Different organizations from

3900-458: A rough design that provides an adequate response to the particular design problems. There are two basic elements to a building design, the aesthetic and the practical. The aesthetic element includes the layout and visual appearance, the anticipated feel of the materials, and cultural references that will influence the way people perceive the building. Practical concerns include space allocated for different activities, how people enter and move around

4050-447: A sheet showing a plan together with the principal façade. Drawings intended to explain a scheme and to promote its merits. Working drawings may include tones or hatches to emphasize different materials, but they are diagrams, not intended to appear realistic. Basic presentation drawings typically include people, vehicles and trees, taken from a library of such images, and are otherwise very similar in style to working drawings. Rendering

4200-445: A shift to drawing on tracing paper so that mechanical copies could be run off efficiently. The development of the computer had a major impact on the methods used to design and create technical drawings, making manual drawing almost obsolete, and opening up new possibilities of form using organic shapes and complex geometry. Today the vast majority of drawings are created using CAD software. The oldest architectural elevation drawing

4350-556: A skyscraper today, it was record setting. The building of tall buildings in the 1880s gave the skyscraper its first architectural movement, broadly termed the Chicago School , which developed what has been called the Commercial Style. The architect, Major William Le Baron Jenney , created a load-bearing structural frame. In this building, a steel frame supported the entire weight of the walls, instead of load-bearing walls carrying

4500-417: A small surface area of windows. Modern skyscrapers often have a tubular structure , and are designed to act like a hollow cylinder to resist wind, seismic, and other lateral loads. To appear more slender, allow less wind exposure and transmit more daylight to the ground, many skyscrapers have a design with setbacks , which in some cases is also structurally required. As of September 2023 , fifteen cities in

4650-502: A thinner line. Sections are used to describe the relationship between different levels of a building. In the Observatorium drawing illustrated here, the section shows the dome which can be seen from the outside, a second dome that can only be seen inside the building, and the way the space between the two accommodates a large astronomical telescope: relationships that would be difficult to understand from plans alone. A sectional elevation

4800-514: A time, the tallest of which is the 97.2 m (319 ft) high Asinelli Tower. A Florentine law of 1251 decreed that all urban buildings be immediately reduced to less than 26 m. Even medium-sized towns of the era are known to have proliferations of towers, such as the 72 towers that ranged up to 51 m height in San Gimignano . The medieval Egyptian city of Fustat housed many high-rise residential buildings, which Al-Muqaddasi in

4950-466: A variety of shapes, and it could be riveted, ensuring strong connections. The simplicity of a steel frame eliminated the inefficient part of a shear wall, the central portion, and consolidated support members in a much stronger fashion by allowing both horizontal and vertical supports throughout. Among steel's drawbacks is that as more material must be supported as height increases, the distance between supporting members must decrease, which in turn increases

5100-469: A vertical tube-like structural system capable of resisting lateral forces in any direction by cantilevering from the foundation". Closely spaced interconnected exterior columns form the tube. Horizontal loads (primarily wind) are supported by the structure as a whole. Framed tubes allow fewer interior columns, and so create more usable floor space, and about half the exterior surface is available for windows. Where larger openings like garage doors are required,

5250-563: Is 649 feet (198 m) tall to its roof, or 680 feet (210 m) tall when including its spire; it contains 56 stories. The Chanin Building's massing influenced that of other skyscrapers in New York City, including the Wall and Hanover Building , 444 Madison Avenue , and 22 East 40th Street . The design was mostly the work of Rene Paul Chambellan and Jacques Delamarre . The former specialized in architectural sculpture in numerous styles, such as

5400-422: Is a combination of a cross section, with elevations of other parts of the building seen beyond the section plane. Geometrically, a cross section is a horizontal orthographic projection of a building on to a vertical plane, with the vertical plane cutting through the building. Isometric and axonometric projections are a simple way of representing a three dimensional object, keeping the elements to scale and showing

5550-400: Is chosen both to ensure the whole building will fit on the chosen sheet size and to show the required amount of detail. On the scale of one-eighth of an inch to one foot (1:96) or the metric equivalent of 1 to 100, walls are typically shown as simple outlines corresponding to the overall thickness. At a larger scale, half an inch to one foot (1:24) or the nearest common metric equivalent 1 to 20,

5700-406: Is important in most building design, but particularly for skyscrapers since even a small chance of catastrophic failure is unacceptable given the tremendous damage such failure would cause. This presents a paradox to civil engineers : the only way to assure a lack of failure is to test for all modes of failure, in both the laboratory and the real world. But the only way to know of all modes of failure

5850-433: Is largely from the force of the building material itself. In most building designs, the weight of the structure is much larger than the weight of the material that it will support beyond its own weight. In technical terms, the dead load , the load of the structure, is larger than the live load , the weight of things in the structure (people, furniture, vehicles, etc.). As such, the amount of structural material required within

6000-414: Is no universally accepted definition, other than being very tall high-rise buildings . Skyscrapers may host offices, hotels, residential spaces, and retail spaces. One common feature of skyscrapers is having a steel frame that supports curtain walls . This idea was invented by Viollet le Duc in his discourses on architecture. These curtain walls either bear on the framework below or are suspended from

Normally the largest paper size used in modern architectural practice is ISO A0 (841 mm × 1,189 mm or 33.1 in × 46.8 in) or in the USA Arch E (762 mm × 1,067 mm or 30 in × 42 in) or Large E size (915 mm × 1,220 mm or 36 in × 48 in). Architectural drawings are drawn to scale so that relative sizes are correctly represented. The scale

The fourth story is faced with ornate terracotta panels depicting plants, evoking the stylized forms common in the Art Deco style. There are buttresses on the fifth and sixth stories of the Lexington Avenue elevation's central bays, as well as at the corners of the 30th through 49th stories. The crown, above the Chanin Company's 52nd-story offices, contains abstract-patterned projecting ornamentation, with buttresses outside

New York City developers competed among themselves, with successively taller buildings claiming the title of "world's tallest" in the 1920s and early 1930s, culminating with the completion of the 318.9 m (1,046 ft) Chrysler Building in 1930 and the 443.2 m (1,454 ft) Empire State Building in 1931,

6750-498: Is the most fundamental architectural diagram , a view from above showing the arrangement of spaces in a building in the same way as a map , but showing the arrangement at a particular level of a building. Technically it is a horizontal section cut through a building (conventionally at four feet / one metre and twenty centimetres above floor level), showing walls, windows and door openings, and other features at that level. The plan view includes anything that could be seen below that level:

6900-419: Is to learn from previous failures. Thus, no engineer can be absolutely sure that a given structure will resist all loadings that could cause failure; instead, one can only have large enough margins of safety such that a failure is acceptably unlikely. When buildings do fail, engineers question whether the failure was due to some lack of foresight or due to some unknowable factor. The load a skyscraper experiences

7050-411: The 1916 Zoning Resolution . The Chanin Building was constructed in 1927–1929 on the site of a warehouse, one of the last remaining undeveloped sites around Grand Central Terminal. Upon opening, the building was almost fully rented, and it was the third-tallest building in New York City . Over the years, the upper floors have contained a movie theater, observation deck, and radio broadcast station, while

In addition, the Sterling National Bank took up much of the mezzanine space on the Lexington Avenue side, and a self-service and table-service restaurant opened in the basement. Through the Great Depression , leasing proceeded actively. The building's owners filed to reorganize

7350-622: The Metropolitan Life Insurance Company Tower . The Chanin Building had more floors than the Woolworth, despite being 112 feet (34 m) shorter. Though the Chanin Building was later surpassed in height by other buildings, including the adjacent 1,046-foot (319 m) Chrysler Building that opened a year later, Irwin Chanin was instead focused on attracting tenants with an "efficient, up-to-date" facility. Upon opening,

By 1920, the area had become what The New York Times called "a great civic centre". One site that had yet to be redeveloped was the Manhattan Storage Warehouse, which was built in 1882 and still occupied the site of the Chanin Building. Irwin Chanin

Instead of drawing lines on paper, the computer records equivalent information electronically. There are many advantages to this system: repetition is reduced because complex elements can be copied, duplicated and stored for re-use. Errors can be deleted, and

Other skyscrapers in the style of Socialist Classicism were erected in East Germany ( Frankfurter Tor ), Poland ( PKiN ), Ukraine ( Hotel Moscow ), Latvia ( Academy of Sciences ), and other Eastern Bloc countries. Western European countries also began to permit taller skyscrapers during

There are three entrances to the building's office stories, which are ornamented with eight plaster reliefs of personified figures against a geometric pattern. Two of the reliefs symbolize achievement and success, while

This definition was based on the steel skeleton—as opposed to constructions of load-bearing masonry , which passed their practical limit in 1891 with Chicago's Monadnock Building . What is the chief characteristic of the tall office building? It is lofty. It must be tall. The force and power of altitude must be in it, the glory and pride of exaltation must be in it. It must be every inch

The latter in turn was not surpassed until the 555-foot (169 m) Washington Monument in 1884. However, being uninhabited, none of these structures actually comply with the modern definition of a skyscraper. High-rise apartments flourished in classical antiquity . Ancient Roman insulae in imperial cities reached 10 and more stories.

The Chanin Building's owners were estimated to have evaded $ 138,549 in real estate taxes. The Chanin Building was designated a city landmark by the New York City Landmarks Preservation Commission in 1978, and was added to the National Register of Historic Places in 1980. By

10500-575: The Chanin Building was almost fully rented. The builders projected that by September 1, 1929, the building would be 70 percent rented, though the actual occupancy rate at that date was 92%. Furthermore, in 1930, The New York Times reported that 95 percent of the structure's 710,000 square feet (66,000 m) was occupied by 9,000 workers. Initially, the lobby space was occupied by the Baltimore and Ohio Railroad 's bus terminal, ticket offices, and waiting rooms. The office space included such tenants as

It also had a stage and projection booth, allowing the venue to be used for films, plays, concerts, and radio shows. In addition, tenants used the auditorium for meetings, and the space also held conferences and conventions. The floors above were originally the offices of the Chanin Organization, with an Art Deco restroom that

Historic surveys worth referring to include: Record drawings are also used in construction projects, where "as-built" conditions of the completed building are documented to take account of all the variations made during the course of construction. A comprehensive set of drawings used in

11400-491: The building was used as a transmission site for WQXR-FM starting on December 15, 1941, when it was relocated from Long Island City in Queens . In 1965, the transmitter was moved to the Empire State Building . The completion of the underground Grand Central Terminal in 1913 resulted in the rapid development of Terminal City, the area around Grand Central, as well as a corresponding increase in real-estate prices. Among these were

11550-404: The building, daylight and artificial lighting, acoustics, traffic noise, legal matters and building codes, and many other issues. While both aspects are partly a matter of customary practice, every site is different. Many architects actively seek innovation, thereby increasing the number of problems to be resolved. Architectural legend often refers to designs made on the back of an envelope or on

11700-399: The building. Buildings are rarely a simple rectangular shape in plan, so a typical elevation may show all the parts of the building that are seen from a particular direction. Geometrically, an elevation is a horizontal orthographic projection of a building onto a vertical plane, the vertical plane normally being parallel to one side of the building. Architects also use the word elevation as

11850-412: The buildings (if any) already existing and those that are proposed, usually as a building footprint; roads, parking lots, footpaths, hard landscaping , trees, and planting. For a construction project, the site plan also needs to show all the services connections: drainage and sewer lines, water supply, electrical and communications cables, exterior lighting, etc. Site plans are commonly used to represent

12000-424: The classical designs of the early skyscrapers , instead embracing the uniform international style ; many older skyscrapers were redesigned to suit contemporary tastes or even demolished—such as New York's Singer Building , once the world's tallest skyscraper. German -American architect Ludwig Mies van der Rohe became one of the world's most renowned architects in the second half of the 20th century. He conceived

12150-420: The construction at a larger scale, to show how the component parts fit together. They are also used to show small surface details, for example decorative elements. Section drawings at large scale are a standard way of showing building construction details, typically showing complex junctions (such as floor to wall junction, window openings, eaves and roof apex) that cannot be clearly shown on a drawing that includes

12300-467: The construction of hotels and apartment buildings at Tudor City , Sutton Place , and Lexington and Park Avenues. The first plan for a skyscraper at the Chanin Building site was made in 1925, when a developer proposed a 35-story skyscraper. The Chanins took over an existing 105-year leasehold for the land underneath the Manhattan Storage Warehouse in August 1926. The Chanin brothers initially planned to erect

12450-478: The construction process. The erection of the frame was not without problems: in one incident, the boom of a construction derrick fell from the 20th floor, nearly splitting a truck in half, though no one was injured or killed. The steelwork was completed by that June, and as was tradition at the time, two gold rivets for the Chanin Building were driven into the frame on July 2 to mark this event. The building held its topping out ceremony in August 1928. The structure

12600-644: The creation of a significant number of early skyscrapers, though none of these were steel reinforced and few remain today. Height limits and fire restrictions were later introduced. In the late 1800s, London builders found building heights limited due to issues with existing buildings. High-rise development in London is restricted at certain sites if it would obstruct protected views of St Paul's Cathedral and other historic buildings. This policy, 'St Paul's Heights', has officially been in operation since 1927. Concerns about aesthetics and fire safety had likewise hampered

12750-451: The daytime, the building's crown appeared as a solid mass. The lobby is accessed by passageways from 42nd and 41st Streets, with a side entrance from Lexington Avenue. The lobby is decorated in a "modernistic" style themed around "The City of Opportunity". Eight bronze reliefs, designed by Chambellan, perch above ornate bronze radiator grilles. The grilles depict four categories of physical and mental life. The bronze ornamentation continues in

12900-632: The development of skyscrapers across continental Europe for the first half of the 20th century. By 1940, there were around 100 high-rise buildings in Europe ( List of early skyscrapers ). Some examples of these are the 43 m (141 ft) tall 1898 Witte Huis (White House) in Rotterdam ; the 51.5 m (169 ft) tall PAST Building (1906–1908) in Warsaw ; the Royal Liver Building in Liverpool, completed in 1911 and 90 m (300 ft) high;

13050-402: The early 1960s Bangladeshi-American structural engineer Fazlur Rahman Khan , considered the "father of tubular designs " for high-rises, discovered that the dominating rigid steel frame structure was not the only system apt for tall buildings, marking a new era of skyscraper construction in terms of multiple structural systems . His central innovation in skyscraper design and construction

13200-669: The early phases of the design architects use diagrams to develop, explore, and communicate ideas and solutions. They are essential tools for thinking, problem solving, and communication in the design disciplines. Diagrams can be used to resolve spatial relationships, but they can also represent forces and flows, e.g. the forces of sun and wind, or the flows of people and materials through a building. An exploded view diagram shows component parts dis-assembled in some way, so that each can be seen on its own. These views are common in technical manuals, but are also used in architecture, either in conceptual diagrams or to illustrate technical details. In

13350-416: The environment and loaded structures with decorative elements and extravagant finishes. This approach to design was opposed by Fazlur Khan and he considered the designs to be whimsical rather than rational. Moreover, he considered the work to be a waste of precious natural resources. Khan's work promoted structures integrated with architecture and the least use of material resulting in the smallest impact on

13500-454: The environment. The next era of skyscrapers will focus on the environment including performance of structures, types of material, construction practices, absolute minimal use of materials/natural resources, embodied energy within the structures, and more importantly, a holistically integrated building systems approach. Modern building practices regarding supertall structures have led to the study of "vanity height". Vanity height, according to

13650-462: The eye, its contrast with the background is reduced, its color saturation is reduced, and its color becomes more blue. Not to be confused with aerial view or bird's eye view, which is the view as seen (or imagined) from a high vantage point. In J M Gandy's perspective of the Bank of England (see illustration at the beginning of this article), Gandy portrayed the building as a picturesque ruin in order to show

13800-428: The final image is intended to be almost indistinguishable from a photograph. A sketch is a rapidly executed freehand drawing, a quick way to record and develop an idea, not intended as a finished work. A diagram could also be drawn freehand but deals with symbols, to develop the logic of a design. Both can be worked up into a more presentable form and used to communicate the principles of a design. In architecture,

13950-449: The finished work is expensive and time consuming, so it is important to resolve the design as fully as possible before construction work begins. Complex modern buildings involve a large team of different specialist disciplines, and communication at the early design stages is essential to keep the design moving towards a coordinated outcome. Architects (and other designers) start investigating a new design with sketches and diagrams, to develop

14100-523: The first building in the world to feature a metal-framed glass curtain wall , a design element which creates light, airy interiors and has since been used the world over as a defining feature of skyscrapers". Further developments led to what many individuals and organizations consider the world's first skyscraper, the ten-story Home Insurance Building in Chicago, built in 1884–1885. While its original height of 42.1 m (138 ft) does not even qualify as

14250-417: The floor, stairs (but only up to the plan level), fittings, and sometimes furniture. Objects above the plan level (e.g. beams overhead) can be indicated as dashed lines. Geometrically, plan view is defined as a vertical orthographic projection of an object onto a horizontal plane, with the horizontal plane cutting through the building. A site plan is a specific type of plan, showing the whole context of

14400-491: The framework above, rather than resting on load-bearing walls of conventional construction. Some early skyscrapers have a steel frame that enables the construction of load-bearing walls taller than of those made of reinforced concrete . Modern skyscraper walls are not load-bearing , and most skyscrapers are characterized by large surface areas of windows made possible by steel frames and curtain walls. However, skyscrapers can have curtain walls that mimic conventional walls with

14550-453: The full height of the building. A full set of construction details needs to show plan details as well as vertical section details. One detail is seldom produced in isolation: a set of details shows the information needed to understand the construction in three dimensions. Typical scales for details are 1/10, 1/5 and full size. In traditional construction, many details were so fully standardized, that few detail drawings were required to construct

14700-471: The glass façade skyscraper and, along with Norwegian Fred Severud , designed the Seagram Building in 1958, a skyscraper that is often regarded as the pinnacle of modernist high-rise architecture. Skyscraper construction surged throughout the 1960s. The impetus behind the upswing was a series of transformative innovations which made it possible for people to live and work in "cities in the sky". In

14850-465: The hundred-story John Hancock Center and the massive 442 m (1,450 ft) Willis Tower . Other pioneers of this field include Hal Iyengar , William LeMessurier , and Minoru Yamasaki , the architect of the World Trade Center . Many buildings designed in the 70s lacked a particular style and recalled ornamentation from earlier buildings designed before the 50s. These design plans ignored

15000-427: The internal plan arrangement, a precursor of the cutaway view. A montage image is produced by superimposing a perspective image of a building on to a photographic background. Care is needed to record the position from which the photograph was taken, and to generate the perspective using the same viewpoint. This technique is popular in computer visualization, where the building can be photorealistically rendered, and

15150-434: The latter part of the 20th century, all architectural drawings were manually produced, if not by the architects, then by trained (but less skilled) draftsmen (or drafters ), who did not generate the design, but did make many of the less important decisions. This system has continued with CAD drafting: many design architects have little or no knowledge of CAD software programmes, relying upon others to take their designs beyond

15300-416: The layers of different materials that make up the wall construction are shown. Construction details are drawn to a larger scale, in some cases full size (1 to 1 scale). Scale drawings enable dimensions to be "read" off the drawing, i.e. measured directly. Imperial scales (feet and inches) are equally readable using an ordinary ruler. On a one-eighth inch to one-foot scale drawing, the one-eighth divisions on

15450-409: The lobby are more ornate versions of those outside. The lobby originally contained a "palatial" bus terminal operated by the Baltimore and Ohio Railroad . The terminal was outfitted with marble surfaces and also contained waiting rooms and ticket offices. Buses would pull onto a revolving turntable within the terminal, which received boarding passengers on one side and deposited alighting passengers on

15600-457: The lower floors were used as offices and a bus terminal. The building was designated a New York City landmark in 1978, and was added to the National Register of Historic Places in 1980. The building is at 122 East 42nd Street in the Midtown and Murray Hill neighborhoods of Manhattan in New York City . It is bounded by Lexington Avenue to the east, 42nd Street to the north, and 41st Street to

15750-454: The lower levels of a skyscraper will be much larger than the material required within higher levels. This is not always visually apparent. The Empire State Building 's setbacks are actually a result of the building code at the time ( 1916 Zoning Resolution ), and were not structurally required. On the other hand, John Hancock Center 's shape is uniquely the result of how it supports loads. Vertical supports can come in several types, among which

15900-674: The most common for skyscrapers can be categorized as steel frames, concrete cores, tube within tube design, and shear walls. The wind loading on a skyscraper is also considerable. In fact, the lateral wind load imposed on supertall structures is generally the governing factor in the structural design. Wind pressure increases with height, so for very tall buildings, the loads associated with wind are larger than dead or live loads. Other vertical and horizontal loading factors come from varied, unpredictable sources, such as earthquakes. By 1895, steel had replaced cast iron as skyscrapers' structural material. Its malleability allowed it to be formed into

16050-435: The most complex encountered given the balances required between economics , engineering , and construction management. One common feature of skyscrapers is a steel framework from which curtain walls are suspended, rather than load-bearing walls of conventional construction. Most skyscrapers have a steel frame that enables them to be built taller than typical load-bearing walls of reinforced concrete. Skyscrapers usually have

16200-495: The nearby Graybar Building , Pershing Square Building , and 110 East 42nd Street, were hired to design the Chanin Building. Once the foundation had been laid, the first steel columns were installed in January 1928, with Irwin S. Chanin driving in the first rivet . The steel frame weighed an estimated 15,000 short tons (13,000 long tons) and was held together by 1.5 million rivets and 160,000 bolts. Crowds frequently stopped to observe

16350-424: The office. Chanin also decorated his offices with wrought brass and iron; etched glass; and several types of marbles, woods, and leathers. His reception room had complementary furniture and wall paneling, as well as recessed ceiling lamps. The reception room also contains illuminated panels depicting areas in which Chanin was an active developer, such as bridges, skyscrapers, Broadway theaters , and rapid transit. As

16500-477: The operations of the Lexington Avenue and 42nd Street Corporation, which operated the Chanin Building, in 1947. In subsequent years, the Chanin Building continued to attract tenants such as Guest Keen and Nettlefolds , a Howard Johnson's restaurant, and the Barry Goldwater 1964 presidential campaign 's New York state headquarters. In addition, the building hosted U.S. Chess Championships . Despite this success,

16650-469: The other six depict physical and mental attributes by which those objectives are attained. The base of the building bears black Belgian marble around the storefront windows, which are each made of plate glass . These storefront windows correspond to two bays on upper stories, allowing for wide displays. Directly above, a bronze frieze depicts scenes of evolution, ranging from simple organisms to more complex animals and plants. A second terracotta frieze runs

16800-460: The other. The coach terminal closed after the railroad discontinued all passenger service north of Baltimore in 1958. The third through 48th floors consist almost entirely of leasable office space, while the 49th and 50th floors contain the Chanin brothers' boardroom and offices. When completed, the 50th floor also had a small movie theater (known as the Chanin Auditorium), later converted into

16950-406: The performance of structures, types of materials, construction practices, absolute minimal use of materials and natural resources, energy within the structure, and a holistically integrated building systems approach. LEED is a current green building standard. Architecturally, with the movements of Postmodernism , New Urbanism and New Classical Architecture , that established since the 1980s,

17100-476: The pre-eminent pieces of American Art Deco—a gracefully ornamented, 56-story slab". The fifth edition of the AIA Guide to New York City , published in 2010, characterized the Chanin Building as being "classic style, rather than stylish ephemera. Such distinguished self-improvement seems beyond the grasp of current developers." The interior design of the building was also praised. Herbert Muschamp wrote in 1992 that

17250-719: The price of steel decreased and labor costs increased. The steel frames become inefficient and uneconomic for supertall buildings as usable floor space is reduced for progressively larger supporting columns. Since about 1960, tubular designs have been used for high rises. This reduces the usage of material (more efficient in economic terms – Willis Tower uses a third less steel than the Empire State Building) yet allows greater height. It allows fewer interior columns, and so creates more usable floor space. It further enables buildings to take on various shapes. Elevators are characteristic to skyscrapers. In 1852 Elisha Otis introduced

17400-421: The relationship between several sides of the same object, so that the complexities of a shape can be clearly understood. There is some confusion over the distinction between the terms isometric and axonometric. "Axonometric is a word that has been used by architects for hundreds of years. Engineers use the word axonometric as a generic term to include isometric, diametric and trimetric drawings." This article uses

17550-430: The ruler can be read off as feet. Architects normally use a scale ruler with different scales marked on each edge. A third method, used by builders in estimating, is to measure directly off the drawing and multiply by the scale factor. Dimensions can be measured off drawings made on a stable medium such as vellum. All processes of reproduction introduce small errors, especially now that different copying methods mean that

17700-474: The safety elevator at the E. V. Haughwout Building in New York City, allowing convenient and safe transport to buildings' upper floors. Otis later introduced the first commercial passenger elevators to the Equitable Life Building in 1870, considered by some architectural historians to be the first skyscraper. Another crucial development was the use of a steel frame instead of stone or brick, otherwise

17850-643: The safety elevator, allowing convenient and safe passenger movement to upper floors. Another crucial development was the use of a steel frame instead of stone or brick, otherwise the walls on the lower floors on a tall building would be too thick to be practical. Today major manufacturers of elevators include Otis , ThyssenKrupp , Schindler , and KONE . Advances in construction techniques have allowed skyscrapers to narrow in width, while increasing in height. Some of these new techniques include mass dampers to reduce vibrations and swaying, and gaps to allow air to pass through, reducing wind shear. Good structural design

18000-559: The same drawing may be re-copied, or copies made in several different ways. Consequently, dimensions need to be written ("figured") on the drawing. The disclaimer "Do not scale off dimensions" is commonly inscribed on architects' drawings, to guard against errors arising in the copying process. This section deals with the conventional views used to represent a building or structure. See the Types of architectural drawing section below for drawings classified according to their purpose. A floor plan

18150-512: The sketch stage. Draftsmen often specialize in a type of structure, such as residential or commercial, or in a type of construction: timber frame, reinforced concrete, prefabrication, etc. The traditional tools of the architect were the drawing board or drafting table, T-square and set squares , protractor , compasses , pencil , and drawing pens of different types. Drawings were made on vellum , coated linen , and tracing paper . Lettering would either be done by hand, mechanically using

18300-433: The south elevation on 41st Street, the entirety of the facade is set back at a uniform depth. The central bays of the eastern elevation on Lexington Avenue are set back at the fifth story, while the outer bays continue upward without setting back. According to one writer, this made the Lexington Avenue elevation appear as a "giant medieval two-towered facade". The subsequent stories form a jagged "pyramid", with setbacks above

18450-543: The south. The lot measures 125 feet (38 m) along 42nd Street, 175 feet (53 m) along 41st Street, and 197.5 feet (60.2 m) along Lexington Avenue. The building is assigned its own ZIP Code , 10168; it was one of 41 buildings in Manhattan that had their own ZIP Codes as of 2019. The Chanin Building is part of the Terminal City area around Grand Central Terminal ; directly to the west are 110 East 42nd Street and

18600-494: The speed of drafting allows many permutations to be tried before the design is finalized. On the other hand, CAD drawing encourages a proliferation of detail and increased expectations of accuracy, aspects which reduce the efficiency originally expected from the move to computerization. Professional CAD software such as AutoCAD is complex and requires both training and experience before the operator becomes fully productive. Consequently, skilled CAD operators are often divorced from

18750-423: The terms in the architecture-specific sense. Despite fairly complex geometrical explanations, for the purposes of practical drafting the difference between isometric and axonometric is simple (see diagram above). In both, the plan is drawn on a skewed or rotated grid, and the verticals are projected vertically on the page. All lines are drawn to scale so that relationships between elements are accurate. In many cases

18900-438: The title for six years. The design and construction of skyscrapers involves creating safe, habitable spaces in very tall buildings. The buildings must support their weight, resist wind and earthquakes, and protect occupants from fire. Yet they must also be conveniently accessible, even on the upper floors, and provide utilities and a comfortable climate for the occupants. The problems posed in skyscraper design are considered among

19050-687: The tube frame must be interrupted, with transfer girders used to maintain structural integrity. Tube structures cut down costs, at the same time allowing buildings to reach greater heights. Concrete tube-frame construction was first used in the DeWitt-Chestnut Apartment Building , completed in Chicago in 1963, and soon after in the John Hancock Center and World Trade Center . The tubular systems are fundamental to tall building design. Most buildings over 40 stories constructed since

19200-474: The tube structure was the Chestnut De-Witt apartment building, considered to be a major development in modern architecture. These new designs opened an economic door for contractors, engineers, architects, and investors, providing vast amounts of real estate space on minimal plots of land. Over the next fifteen years, many towers were built by Fazlur Rahman Khan and the " Second Chicago School ", including

19350-472: The upper rented to the lower classes. Surviving Oxyrhynchus Papyri indicate that seven-stories buildings existed in provincial towns such as in 3rd century AD Hermopolis in Roman Egypt . The skylines of many important medieval cities had large numbers of high-rise urban towers, built by the wealthy for defense and status. The residential Towers of 12th century Bologna numbered between 80 and 100 at

19500-460: The walls on the lower floors on a tall building would be too thick to be practical. An early development in this area was Oriel Chambers in Liverpool , England, built in 1864. It was only five floors high. The Royal Academy of Arts states, "critics at the time were horrified by its 'large agglomerations of protruding plate glass bubbles'. In fact, it was a precursor to Modernist architecture, being

19650-448: The waves on the floor, mailboxes, and elevator doors, extending the general Art Deco style from the outside inward. The lobby also contains other ornamentation such as terrazzo floors with bronze inlays, as well as tan marble walls. Originally, the floors had lozenge-shaped panels, but heavy pedestrian traffic wore down these panels over the years. Marble stairs lead to the basement where there are connections to Grand Central Terminal and

19800-604: The weight of the building. This development led to the "Chicago skeleton" form of construction. In addition to the steel frame, the Home Insurance Building also utilized fireproofing, elevators, and electrical wiring, key elements in most skyscrapers today. Burnham and Root 's 45 m (148 ft) Rand McNally Building in Chicago, 1889, was the first all-steel framed skyscraper, while Louis Sullivan 's 41 m (135 ft) Wainwright Building in St. Louis, Missouri, 1891,

19950-416: The whole length of the lower facade, presenting a dramatic collection of angular zigzags and curvy leaves. A bas-relief by Edward Trumbull , designed in the Art Deco style, wraps around the facade. The facade continues upward in relatively simple tones. The second and third floors include bronze-framed groups of triple-paned windows, with bronze Art Deco spandrel panels between the floors. Each grouping

20100-814: The world have more than 100 skyscrapers that are 150 m (492 ft) or taller: Hong Kong with 552 skyscrapers; Shenzhen , China with 373 skyscrapers; New York City , US with 314 skyscrapers; Dubai , UAE with 252 skyscrapers; Guangzhou , China with 188 skyscrapers; Shanghai , China with 183 skyscrapers; Tokyo , Japan with 168 skyscrapers; Kuala Lumpur , Malaysia with 156 skyscrapers; Wuhan , China with 149 skyscrapers; Chongqing , China, with 144 skyscrapers; Chicago , US, with 137 skyscrapers; Chengdu , China with 117 skyscrapers; Jakarta , Indonesia , with 112 skyscrapers; Bangkok , Thailand , with 111 skyscrapers, and Mumbai , India with 102. As of 2024, there are over 7 thousand skyscrapers over 150 m (492 ft) in height worldwide. The term "skyscraper"

20250-648: The world's tallest building for forty years. The first completed 417 m (1,368 ft) tall World Trade Center tower became the world's tallest building in 1972. However, it was overtaken by the Sears Tower (now Willis Tower ) in Chicago within two years. The 442 m (1,450 ft) tall Sears Tower stood as the world's tallest building for 24 years, from 1974 until 1998, until it was edged out by 452 m (1,483 ft) Petronas Twin Towers in Kuala Lumpur, which held

20400-432: The world's tallest building, New York took the lead by 1895 with the completion of the 103 m (338 ft) tall American Surety Building , leaving New York with the title of the world's tallest building for many years. Modern skyscrapers are built with steel or reinforced concrete frameworks and curtain walls of glass or polished stone . They use mechanical equipment such as water pumps and elevators . Since

20550-470: The world, although only partially iron framed, is The Flaxmill in Shrewsbury , England. Built in 1797, it is seen as the "grandfather of skyscrapers", since its fireproof combination of cast iron columns and cast iron beams developed into the modern steel frame that made modern skyscrapers possible. In 2013 funding was confirmed to convert the derelict building into offices. In 1857, Elisha Otis introduced

20700-650: The years immediately following World War II. Early examples include Edificio España (Spain) and Torre Breda (Italy). From the 1930s onward, skyscrapers began to appear in various cities in East and Southeast Asia as well as in Latin America . Finally, they also began to be constructed in cities in Africa , the Middle East , South Asia , and Oceania from the late 1950s. Skyscraper projects after World War II typically rejected

20850-475: Was "design[ed] in masses rather than in facades". The Chanin Building's massing was inspired by that of Eliel Saarinen's unbuilt proposal for Chicago's Tribune Tower . Though the building is primarily designed in the Art Deco style, the massing also exhibits design characteristics of the International Style . The lowest four stories occupy the entire land lot. Along the north elevation on 42nd Street and

21000-564: Was an American architect and real estate developer who designed several Art Deco towers and Broadway theaters. He and his brother Henry I. Chanin designed their first Manhattan buildings in 1924. They then built and operated a number of theaters and other structures related to the entertainment industry, including the Roxy Theatre and the Hotel Lincoln . Chanin believed the area around Grand Central Terminal had potential for growth because of

21150-515: Was declared complete on January 23, 1929, exactly one year after the first rivet had been driven into the building. It opened January 29 at an estimated cost of $ 12-14 million, with an informal opening attended by mayor Jimmy Walker . The Chanin Building thus became the first major skyscraper in Terminal City, and the third-tallest building in New York City behind the Woolworth Building and

21300-478: Was designed in the Art Deco style by John Sloan and T. Markoe Robertson of the firm Sloan & Robertson, with the assistance of Chanin's architect Jacques Delamarre. It incorporates architectural sculpture by Rene Paul Chambellan , as well as a facade of brick and terracotta . The skyscraper reaches 680 feet (210 m), with a 649-foot-tall (198 m) roof topped by a 31-foot (9.4 m) spire. The Chanin Building includes numerous setbacks to conform with

21450-580: Was difficult to clear, since its 5-foot-thick (1.5 m) walls had been designed to protect against "burglary, fire and assault". The process entailed clearing away 7,500 truck loads of brick, 1,000 of scrap metal, and 3,500 of loose earth. The official plans for the Chanin Building were filed with the New York City Department of Buildings in June 1927, at which point 60 percent of the warehouse had been demolished. Sloan & Robertson, architects of

21600-611: Was first applied to buildings of steel-framed construction of at least 10 stories in the late 19th century, a result of public amazement at the tall buildings being built in major American cities like New York City , Philadelphia , Boston , Chicago , Detroit , and St. Louis . The first steel-frame skyscraper was the Home Insurance Building , originally 10 stories with a height of 42 m or 138 ft, in Chicago in 1885; two additional stories were added. Some point to Philadelphia's 10-story Jayne Building (1849–50) as

21750-456: Was found in a piece of white terracotta crucibles unearthed in China, dated 7400 years ago. It shows 2 stilted watch towers (or light houses) with spiral staircase above water. The size of drawings reflects the materials available and the size that is convenient to transport – rolled up or folded, laid out on a table, or pinned up on a wall. The drafting process may impose limitations on the size that

21900-424: Was in 17th-century Edinburgh , Scotland, where a defensive city wall defined the boundaries of the city. Due to the restricted land area available for development, the houses increased in height instead. Buildings of 11 stories were common, and there are records of buildings as high as 14 stories. Many of the stone-built structures can still be seen today in the old town of Edinburgh. The oldest iron framed building in

22050-483: Was included, the building techniques involved being common knowledge amongst building professionals. Modern working drawings are much more detailed and it is standard practice to isolate select areas of the project on separate sheets. Notes included on drawings are brief, referring to standardized specification documents for more information.
