In a garden, the goal is to keep it clean of weeds. If you let the weeds grow, they can quite possibly take over the whole garden. Explosive demolition is the weed puller of buildings. It is key in keeping whole communities up to date. It may be hard to think that using explosives can actually make an area safer, but these professionals do it all of the time. If a building is not structurally sound, there is the chance that it can collapse at any time. This is why explosive demolition is so important because it basically weeds out the buildings that have the potential to harm people. Being an explosive demolition engineer takes hard work, critical thinking, and perseverance.
Explosive demolition is the method of choice when it comes to taking down larger structures with no collateral damage. Basically, if you remove the support structure of a building at a certain point, the section of the building above that point will fall down on the part of the building below that point. If this upper section is heavy enough, it will collide with the lower part with “sufficient force to cause significant damage” (Harris). There is alot of thinking involved in taking down a building and that is why it is such a long process. “A building implosion is actually one of the most precisely planned, delicately balanced engineering feats you'll ever see” (Harris). Some people may think that demolition engineers are just the people who blow up the buildings, but this is not true. In my opinion, demolition engineers are almost like “reverse architects.” “The demolition engineer has physically worked with, manipulated and pulled apart more buildings than probably most structural engineers will ever design in a lifetime”(Clark).

As the United States economy struggles through a sluggish time with the stock market dropping and unemployment rising, being competitive in the job market has become extremely important among professionals. Engineers are no exception. For most engineering firms, being competitive and successful requires obtaining design projects offered by companies in other fields. These projects can range from designing heating and ventilation systems for office buildings to water systems for cities to computer networks for businesses—the list of possibilities and disciplines is extensive. To get these jobs, engineers must make a bid proposal for the project. Bidding involves estimating the entire cost of the project, including the designing and building processes, as well as the materials and labor. Usually, the company with the lowest bid and the best plan gets the job. The ethical issue in this process is determining the cheapest building materials and construction procedures possible without compromising public safety.
When designing large structures such as bridges, ships, dams and various modes of transportation, engineers must determine what methods and materials should be used in order to design, construct, and maintain the structure for a long period of time. A strict code of ethics must be followed in order to reduce any possible damages and tragedies. Though this process is used to try and minimize any design errors and possible failures, unknown factors such as population increase, natural disasters, and insufficient manpower can cause the structure to fail. Such is the case for the I-35W Mississippi River Bridge and the Mianus River Bridge.
The attacks of September 11 were some of the worst ever experienced in the history of the United States. These attacks generated a widespread feeling of insecurity and uncertainty throughout America, compelling the government to revise safety measures and protocol pertaining to the wellbeing of the United States. However, some aspects of security under modification, such as building codes, are being questioned by many. The collapse of the twin towers, due to the impact from the airplanes, spurred a movement focused on strengthening the integrity of skyscrapers and other high-rise buildings throughout the United States. Though the terrorist attacks proved to be a tremendous tragedy, the application of measures this great is not seen as a proven necessity. The circumstances of the incident proved to be so extraordinary that dramatic modifications to the structure of building should not take place because of such an event. Therefore, the building codes of skyscrapers should not be changed due to the terrorist attacks of September 11.
This report will investigate the structural makeup of the commercial building we are working on as part of the Studio 2 module. The building has a single-storey basement that is to be used for car parking, with 5 upper storeys comprising of a café and open plan offices. This report investigates firstly the site that the building is situated on, secondly, the structural make-up of the building, thirdly the load trace and finally, materials used along with reasons for choosing them.
Structural Engineers are one of the many trained professionals who are classified under forensic engineering. Structural Engineers (SEs) deal with the frameworks and skeletons of buildings, bridges, towers, stadiums, tunnels, and even roller coasters; in short, virtually every aspect of our world’s built environment. SEs works with other engineers—mechanical, geotechnical, electrical, and civil—as well as urban planners and architects. SEs design the components of a structure that hold its contents—“contents” being people, vehicles, and other property. In buildings, SEs design roof framing, floor framing, arches, columns, frames, foundations, and walls. They work with a broad range of materials, including steel, concrete, wood, masonry, and aluminum. SEs must design structures to resist forces from gravity, earthquakes, high winds, water, collisions, and explosions. They develop their designs by performing a complex series of calculations and by utilizing computer programs. The primary duty of a structural engineer is to ensure public safety and to serve the client’s interests while abiding by the appropriate standards and legal codes, which are commonly refer to as building codes.

Punctuality, the sense of responsibility and the spirit of hard-working are three characteristics which play an essential role in the engineer’s career. In construction site, the quality of many building materials like concrete and mud can change within a short period. If we failed to use them before their self-deterioration punctually, the probability of failure would extremely increases and people would have to live or work in there under a big safety risk and potential financial loss. Also, the sense of responsibility is important. With increasing number of designing institutes have been established, all of engineers are facing a huge competition when participating the project bidding and trying their best so hard to minimize construction cost. Under this condition, we have the responsibility to ensure the quality of the project without being infected by fin...
Building structure and bridge structure, though built with well-considered design, may still have structural problem or even collapse with time. In this regard, the designer of the structure, which is the civil engineer, may have to bear of responsibility of professional negligence. Nonetheless, most of the engineers should be professional and have followed good control of structure quality, code of practice and good on-site supervision, despite the structure built may fail after the construction. To defense themselves, engineers involved should focus on their legal responsibility on the structure and other factors that lead to the failure of the structure.

The history of construction is a very complex subject regarding to the materials used, building techniques, modes of transpotation, machinery used, and workforce used. But with the passage of time mankind has excelled in every field of life. The eagerness to live a comfortable and lavish life has become more than a passion for people. They work hard to make their life style better. And with the advancement in every field of life there have been very rapid changes in the field of construction too. But still there is always space for something new.
Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in the understanding of physics and mathematics throughout history. Precise measurements are key in creating the magnificent structures seen today. Knowing all the minute details throughout every inch of a project is the first thing in an engineer’s mind. Questions such as “Is this 100% safe?” become priorities. The stability and safety of every idea that emerges from an engineer’s imagination need to be tested repeatedly and with accuracy. Having a background in mathematics and physics allow the analysis of every possible aspect when it comes to construction of houses, hotels, and every building that stands today. Regardless of the size of a project, every element is addressed. Using their creativity and backg...
