When driving into a city the horizon is always very awe dropping, highlighted by the various high-rises and skyscrapers that outline the city. The Council on Tall Buildings and Urban Habitat (CTBUH) defines a high-rise building as “a building whose height of over 75 feet creates different conditions in the design, construction, and use than those that exist in common buildings of a certain region and period” (CTBUH). High-rise buildings exist in our civilization, mostly in our large cities, to save space and money. “In large urban areas, cost of construction is 87% cheaper to build up than it is to build outward” (NFPA). In urban areas, land space is limited and very valuable. Skyscrapers can house different purposes consisting of; office space, apartment living, and even entertainment purposes. These types of buildings present several unique challenges not found in traditional low-rise buildings; longer egress times and distance, evacuation strategies, fire department accessibility, smoke movement and fire control. Dr. W. Z. Black is a member of the American Society of Fire Safety and Engineers; He stated, “During an emergency, the multiple floors of a high-rise building require great numbers of persons to travel great vertical distances on stairs in order to evacuate the building” (Black). Based on the numerous issues and concerns found within high-rise buildings, it is evident that fire safety is a major problem.
High-rise buildings have garnered significant attention in
At the time of the MGM Grand Fire, it was not required that fire department personnel had to be part of the building construction plan review process. The fire department is now largely involved in the construction and plan review process before a building is built. Also, construction materials used are more fire resistant. Ventilation systems have also been improved, and are very helpful in removing the smoke, rather than allowing it to make its way to upper floors of a high rise structure, which was a large cause of loss of life in the MGM Grand fire due to smoke inhalation and carbon monoxide poisoning.
One of the innovations was the construction of skyscrapers. Before steel was used, a skyscraper was only considered four to five stories tall and was made out of stone. Very little light was able to get into the building because the structure would become unsafe if too many windows were put in. This made the building very dark, cold and damp. In 1885, with the innovation of steel, the first skyscraper, The Home Insurance Building, was built in Chicago, Illinois. This building paved the way for architects around the country to build taller and stronger skyscrapers into today’s times.
Steel fabrication: this is when steel is cut to the desire length generally on site and then weld them together to create the final building. This is generally labor intensive however it can reduce time.
No steel-beam high-rise had ever before (or since) completely collapsed due to fires! However, such complete and nearly symmetrical collapses in tall steel-frame buildings have occurred many times before—all of them due to pre-positioned explosives in a procedure called “implosion” or controlled demolition.

The focus of this assessment is to identify safety concerns about the physical structures of the University of Texas at San Antonio Downtown campus. Throughout the assessment there were several safety issues that were noted those which include but are not limited to lack of ramps, proximity of buildings, placement of cameras, parking lot safety, place of emergency evacuation chairs, placements of fire extinguishers and AED’s. It is very important to be aware of safety concerns students, faculty, and staff may encounter to keep the university not only safe but also secure.
Throughout this paper, I will examine eight disastrous events that led to the establishment of new buildings codes. The tragedies that took place during these events paved way for, new and improved codes that were implemented to help protect health, safety, and the natural resources that sustain us. The eight different events that I chose to research, I felt had the most significant impact in the development of some of the most commonly used building codes today. The first event that I will discuss is 9/11, 9/11 is one of the worst terrorist attacks on American soil. The second event is one of the largest hotel fires that ever broke out, which happened on November 21, 1980, at the MGM Grand Hotel in Las Vegas, Nevada. The third event that I
In other words, “Ordinarily, people think that wealth is increased and life is far more attractive and thrilling; for if this were not so, who would be drawn into New York, Chicago, Los Angeles, Detroit, Philadelphia…”(Mumford). The development of skyscrapers was only introduced for cities to boast about the amount of money they have, so then people would be captivated by a city's image and heighten their reputation. A consequence of this action is the establishment of multiple skyscrapers creates a safety hazard for the public. Namely, if there was ever an earthquake that was strong enough to cause the skyscrapers to break apart, people’s lives would be in danger as the people would be trapped inside or the debris would be crashing down upon the streets (Twenties in Contemporary Commentary, The). Public services such as policemen or firefighters were not equipped or prepared to handle these types of situations, if one was ever to occur. Skyscrapers were not only a waste of money, but a result of this impractical building could harm the lives of citizens living in
The lack of fire suppression in the buildings hampers property owners from being able to rent the commercial spaces on the first floor. If the use changes code
Wealthy Heights was developed by Dutch immigrants who flocked to the area to work for a greenhouse. They built simple and cottage-style small houses in the area (Figure 1). The closing of this greenhouse and suburbanization in the 1960s and 70s fostered the declination of this neighborhood. By the mid-1990s, many residential buildings were abandoned (City of East Grand Rapids, 2014; East Hills Council of Neighbors, 2005; Grand Rapids Historic Preservation Commission, 2007).
Multi-story parking facilities have been proven to be problematic and very susceptible to collapse during an earthquake. Multi-story
Green buildings could become one of the main factors to preserve our rapidly decaying environment. There is no easy way to define a green building, but a green building is essentially a structure that amplifies the positives and mitigates the negatives throughout the entire life cycle of the building (Kriss, 2014). There are many definitions for a green building, but all of them include the planning, designing, constructing, and operating of the building while taking into huge considerations of the energy use, water use, indoor air environment, materials used and the effect it has on the site the green building is being built on. The first green buildings dates back to as far as the 1970’s, when solar panels went from experiments to reality. Green buildings were not as popular as they are today due to their extremely high pricing. With technology rapidly growing, solar panels are becoming cheaper and cheaper, making the transition to creating green buildings more affordable. This is the primary reason for the increased growth of green buildings today. A modern company that is paving the way to the growth of green buildings named LEED, Leadership in Energy and Environmental Design, focuses primarily on new and effective ideas for environmentally friendly buildings projects. With more than 60,000 commercial projects worldwide and 1.7 million square feet being certified every day, LEED is one of the leading groups for promoting green buildings. LEED has popularized the entire
This is an analysis potentially applied to the Alfred P. Murrah building; the Murrah Building was relatively a low-risk building. In honesty, the building was not notable, it was not a landmark, nor was it of critical importance. But, the use of standoff distance should still be incorporated. The installation of bollards is relatively low cost. The benefits of standoff distance are not only that of protecting but that of a more public setting. It removes buildings from the street-fronts, opening the sidewalk for more potential public spaces (The National Capital Urban Design and Security Plan). While this concept is not applicable to all locations, such as densely packed New York City, it is certainly applicable to the more sparsely spaced Oklahoma city. The empty standoff distance is not the only usable space that would be able to benefit the public, bollards have even been designed to incorporate built-in benches. This adds daily

His first comprehensive city plan was La Ville Contemporaine (the Contemporary City) a project to house three million inhabitants designed in 1922. This was Le Corbusier’s first attempt to reconcile man, nature and machine (Fishman, 189). The city starts at the center with a transportation hub for busses, trains, cars and planes. Surrounding this hub there will be an organized cluster of 24 60-story skyscrapers. These glass and steel skyscrapers are cross-shaped. Each individual skyscraper is to be set within a large rectangular green space. The skyscrapers house the “brain” of the city. The city is beautifully geometric and symmetrical. Placing the skyscrapers in the city center reinforces the emphasis on capital as a means of creating a successful city. Because of the shape and mass of each skyscraper, they have more usable space than an entire neighborhood but also relieves density and congestion because of the organization (Frampton, 46).
