Singer Building
The Singer Building (also known as the Singer Tower) was an office building and early skyscraper in Manhattan, New York City. The headquarters of the Singer Manufacturing Company, it was at the northwestern corner of Liberty Street and Broadway in the Financial District of Lower Manhattan. Frederick Gilbert Bourne, leader of the Singer Company, commissioned the building, which architect Ernest Flagg designed in multiple phases from 1897 to 1908. The building's architecture contained elements of the Beaux-Arts and French Second Empire styles. The building was composed of four distinct sections. The original 10-story Singer Building at 149 Broadway was erected between 1897 and 1898, and the adjoining 14-story Bourne Building on Liberty Street was built from 1898 to 1899. In the first decade of the 20th century, the two buildings were expanded to form the 14-story base of the Singer Tower, which rose another 27 stories. The facade was made of brick, stone, and terraco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philadelphia City Hall
Philadelphia City Hall is the seat of the municipal government of the City of Philadelphia. Built in the ornate Second Empire style, City Hall houses the chambers of the Philadelphia City Council and the offices of the Mayor of Philadelphia. It is also a courthouse, serving as the seat of the First Judicial District of Pennsylvania, and houses the Civil Trial and Orphans' Court Divisions of the Court of Common Pleas of Philadelphia County. Built of brick, white marble, and limestone, Philadelphia City Hall is the world's largest free-standing masonry building and was the world's tallest habitable building upon its completion in 1894. In 1976, it was designated a National Historic Landmark, and in 2006, was also named a National Historic Civil Engineering Landmark by the American Society of Civil Engineers.

Architectural Terracotta
Architectural terracotta refers to a fired mixture of clay and water that can be used in a non-structural, semi-structural, or structural capacity on the exterior or interior of a building. Terracotta pottery, as earthenware is called when not used for vessels, is an ancient building material that translates from Latin as " baked earth". Some architectural terracotta is actually the stronger stoneware. It can be unglazed, painted, slip glazed, or glazed. A piece of terracotta is composed of a hollow clay web enclosing a void space or cell. The cell can be installed in compression with mortar or hung with metal anchors. All cells are partially backfilled with mortar. By the late 19th century the version with a ceramic glaze, namely glazed architectural terracotta became more popular. Chemistry Terracotta is made of a clay or silt matrix, a fluxing agent, and grog or bits of previously fired clay. Clays are the remnants of weathered rocks that are smaller than 2 microns. They ...

City Investing Building
The City Investing Building, also known as the Broadway–Cortlandt Building and the Benenson Building, was an office building and early skyscraper in Manhattan, New York. Serving as the headquarters of the City Investing Company, it was on Cortlandt Street between Church Street and Broadway in the Financial District of Lower Manhattan. The building was designed by Francis Kimball and constructed by the Hedden Construction Company. Because of the area's sloping topography, the City Investing Building rose 32 stories above Broadway and 33 stories above Church Street, excluding an attic. The bulk of the building was 26 stories high above Church Street and was capped by a seven-story central portion with gable roofs. The building had an asymmetrical F-shaped footprint with a light court facing Cortlandt Street, as well as a wing to Broadway that wrapped around a real estate holdout, the Gilsey Building. Inside was a massive lobby stretching between Broadway and Church Street. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tallest Voluntarily Demolished Buildings
Voluntary building demolition is the decision by either the landowner or a higher government body to demolish a structure for any number of reasons, ranging from severe structural damage to the redevelopment of the land the building sits upon. Involuntary (or unplanned) building demolitions, such as the collapse of a building during a severe earthquake or by a terrorist attack, are not included in this list. Tallest voluntarily demolished buildings over 100 meters (328 feet) in height The demolition of especially high buildings presents unique challenges, especially when their location is within densely populated areas of their respective cities. Buildings in excess of 100 meters (328 ft) in height are most often deconstructed floor-by-floor down to the building's basement, as opposed to controlled Building implosion, implosion of the structure, which would most likely damage surrounding structures. Tallest voluntarily demolished buildings 50 meters (164 feet) to 100 meter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Skyscraper
A skyscraper is a tall continuously habitable building having multiple floors. Modern sources currently define skyscrapers as being at least or in height, though there is no universally accepted definition. Skyscrapers are very tall high-rise buildings. Historically, the term first referred to buildings with between 10 and 20 stories when these types of buildings began to be constructed in the 1880s. Skyscrapers may host offices, hotels, residential spaces, and retail spaces. One common feature of skyscrapers is having a steel frame that supports curtain walls. These curtain walls either bear on the framework below or are suspended from 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 skyscrapers' walls are not load-bearing, and most skyscrapers are characterised by large surface ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Observation Deck
An observation deck, observation platform, or viewing platform is an elevated sightseeing platform usually situated upon a tall architectural structure, such as a skyscraper or observation tower. Observation decks are sometimes enclosed from weather, and a few may include coin-operated telescopes for viewing distant features.

Stone Veneer
Stone veneer is a thin layer of any stone used as decorative facing material that is not meant to be load bearing. Stone cladding is a stone veneer, or simulated stone, applied to a building or other structure made of a material other than stone. Stone cladding is sometimes applied to concrete and steel buildings as part of their original architectural design. History Thin stone veneer was first developed in the late 19th century, but there were materials developed much earlier that foreshadowed its use. For instance, the ancient Romans built large structures out of Roman concrete, and sometimes used a form of stone veneer to face them. Parts of the Roman Coliseum were originally faced with marble veneer; the holes which once held the anchors for the veneer are still visible. Modern stone veneer first made its appearance in the late 1800s. The oldest of modern stone veneer product is now disintegrating. It was cut into thick portions and then hand tooled into the appropriate pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marble
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or Dolomite (mineral), dolomite. Marble is typically not Foliation (geology), foliated (layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for Marble sculpture, sculpture and as a building material. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shining stone", perhaps from the verb (), "to flash, sparkle, gleam"; Robert S. P. Beekes, R. S. P. Beekes has suggested that a "Pre-Greek origin is probable". This Stem (linguistics), stem is also the ancestor of the English language, English word "marmoreal," meaning "marble-like." While the English term "marble" resembles the French language, French , most other European languages (with words like "marmoreal") more closely resemb ...

Load-bearing Wall
A load-bearing wall or bearing wall is a wall that is an active structural element of a building, which holds the weight of the elements above it, by conducting its weight to a foundation structure below it. Load-bearing walls are one of the earliest forms of construction. The development of the flying buttress in Gothic architecture allowed structures to maintain an open interior space, transferring more weight to the buttresses instead of to central bearing walls. In housing, load-bearing walls are most common in the light construction method known as "platform framing". In the birth of the skyscraper era, the concurrent rise of steel as a more suitable framing system first designed by William Le Baron Jenney, and the limitations of load-bearing construction in large buildings, led to a decline in the use of load-bearing walls in large-scale commercial structures.

Steel Frame
Steel frame is a building technique with a "skeleton frame" of vertical steel columns and horizontal I-beams, constructed in a rectangular grid to support the floors, roof and walls of a building which are all attached to the frame. The development of this technique made the construction of the skyscraper possible. Concept The rolled steel "profile" or cross section of steel columns takes the shape of the letter "". The two wide flanges of a column are thicker and wider than the flanges on a beam, to better withstand compressive stress in the structure. Square and round tubular sections of steel can also be used, often filled with concrete. Steel beams are connected to the columns with bolts and threaded fasteners, and historically connected by rivets. The central "web" of the steel I-beam is often wider than a column web to resist the higher bending moments that occur in beams. Wide sheets of steel deck can be used to cover the top of the steel frame as a "form" or corrugated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caisson (engineering)
In geotechnical engineering, a caisson ( or ; borrowed from French ''caisson'', from Italian ''cassone'', meaning ''large box'', an augmentative of ''cassa'') is a watertight retaining structure used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is erected. Caisson engineering has been used at least since the 18th century, and was notably used in the construction of the Brooklyn Bridge, which was completed in 1883. Types To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is pref ...
