United Steelworkers Building
The United Steelworkers Building, originally named the IBM Building and also known as the I.W. Abel Building or Five Gateway Center, is a highrise office building in Downtown Pittsburgh, Pennsylvania. It was built by the Equitable Life Assurance Society in 1961–64 as part of the Gateway Center project which redeveloped a large portion of the area known as the Point. The building is listed on the National Register of Historic Places as a contributing property in the Pittsburgh Renaissance Historic District and has been designated as a Pittsburgh landmark by the Pittsburgh History and Landmarks Foundation. The building was designed by Curtis and Davis, a New Orleans-based architecture firm, with structural engineers Worthington, Skilling, Helle & Jackson. The design of the building, featuring a load-bearing steel diagrid exoskeleton, was highly unusual at the time and helped pioneer the use of diagrids and framed tube construction. History The building was developed by the ...

Boulevard Of The Allies
The Boulevard of the Allies is a mostly four-lane road in the U.S. state of Pennsylvania, connecting Downtown Pittsburgh with the Oakland neighborhood of the city. Because of its lengthy name, locals sometimes refer to it as simply "The Boulevard". Some sections are part of Pennsylvania Route 885. The road begins in Downtown Pittsburgh at its intersection with Commonwealth Place and an offramp from Interstate 279. The road continues east through Downtown passing Point Park University and the former Art Institute of Pittsburgh building to Grant Street where it becomes elevated to transition from the flat plain of Downtown to the bluff that Oakland sits on. Before reaching Oakland, it passes by Duquesne University and Mercy Hospital along the edge of a cliff several hundred feet above the Monongahela River with views of the city's South Side neighborhood and includes partial interchanges with Interstate 579 and Interstate 376. At its interchange with I-579, the road is split; ...

World Trade Center (1973–2001)
The original World Trade Center (WTC) was a large complex of seven buildings in the Financial District of Lower Manhattan in New York City. It opened on April 4, 1973, and was destroyed in 2001 during the September 11 attacks. At the time of their completion, the Twin Towers—the original 1 World Trade Center (the North Tower) at ; and 2 World Trade Center (the South Tower) at —were the tallest buildings in the world. Other buildings in the complex included the Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC. The complex contained of office space. The core complex was built between 1966 and 1975, at a cost of $400 million (equivalent to $3.56 billion in 2022). The idea was suggested by David Rockefeller to help stimulate urban renewal in Lower Manhattan, and his brother Nelson signed the legislation to build it. The buildings at the complex were designed by Minoru Yamasaki. In 1998, the Port Authority of New York and New Jersey decided ...

John Hancock Center
The John Hancock Center is a 100-story, 1,128-foot supertall skyscraper located in Chicago, Illinois. Located in the Magnificent Mile district, the building was officially renamed 875 North Michigan Avenue in 2018. The skyscraper was designed by Peruvian-American chief designer Bruce Graham and Bangladeshi-American structural engineer Fazlur Rahman Khan of Skidmore, Owings and Merrill (SOM). When the building topped out on May 6, 1968, it was the second-tallest building in the world after the Empire State Building, and the tallest in Chicago. It is currently the fifth-tallest building in Chicago and the thirteenth-tallest in the United States, behind the Aon Center in Chicago and ahead of the Comcast Technology Center in Philadelphia. When measured to the top of its antenna masts, it stands at . The building is home to several offices and restaurants, as well as about 700 condominiums, and at the time of its completion contained the highest residence in the world. The buildi ...

Curtain Wall (architecture)
A curtain wall is an outer covering of a building in which the outer walls are non-structural, utilized only to keep the weather out and the occupants in. Since the curtain wall is non-structural, it can be made of lightweight materials, such as glass, thereby potentially reducing construction costs. An additional advantage of glass is that natural light can penetrate deeper within the building. The curtain wall façade does not carry any structural load from the building other than its own dead load weight. The wall transfers lateral wind loads that are incident upon it to the main building structure through connections at floors or columns of the building. A curtain wall is designed to resist air and water infiltration, absorb sway induced by wind and seismic forces acting on the building, withstand wind loads, and support its own weight. Curtain walls may be designed as "systems" integrating frame, wall panel, and weatherproofing materials. Steel frames have largely given w ...

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 ...

Labor Union
A trade union (labor union in American English), often simply referred to as a union, is an organization of workers intent on "maintaining or improving the conditions of their employment", ch. I such as attaining better wages and benefits (such as holiday, health care, and retirement), improving working conditions, improving safety standards, establishing complaint procedures, developing rules governing status of employees (rules governing promotions, just-cause conditions for termination) and protecting the integrity of their trade through the increased bargaining power wielded by solidarity among workers. Trade unions typically fund their head office and legal team functions through regularly imposed fees called ''union dues''. The delegate staff of the trade union representation in the workforce are usually made up of workplace volunteers who are often appointed by members in democratic elections. The trade union, through an elected leadership and bargaining committee, b ...

Train Shed
A train shed is a building adjacent to a station building where the tracks and platforms of a railway station are covered by a roof. It is also known as an overall roof. Its primary purpose is to store and protect from the elements train cars not in use, The first train shed was built in 1830 at Liverpool's Crown Street Station. The biggest train sheds were often built as an arch of glass and iron, while the smaller were built as normal pitched roofs. The train shed with the biggest single span ever built was that at the second Philadelphia Broad Street Station, built in 1891. Types of train shed Early wooden train sheds The earliest train sheds were wooden structures, often with unglazed openings to allow smoke and steam to escape. The oldest part of Bristol Temple Meads is a particularly fine – and large – example, designed by Isambard Kingdom Brunel with mock-hammerbeam roof. Surviving examples include: * Ashburton, Devon, England (station closed) *Bo'ness, Falki ...
