Demolition and Renovation of a 40 Story Building - Coursework Example

Demolition and renovation Demolition of a building refers to the act of bringing down a structure usingeffective means and equipments. Demolition requires high-level techniques that will have minimum dangers and cost effective as well. There are different types of demolition, building implosion, dismantling, and selective demolition. Building implosion requires the use of explosive materials that are in specific locations and the right type of explosives. In addition, implosion occurs inwardly and violently bringing down the building with a great impact. The explosives are set inside the building targeting particular support points of the building that if they were in tamper with it would result in collapsing of the building. This type of demolition is underutilization in areas with high population level and in large structures that require violent but effective means. The crew that is in charge of carrying out the demolition needs to study the building with great care so to ensure that the major support points have explosive set targeting them. The dismantling method utilizes the crane mostly, and it is in use to remove parts of walls in a building. It is a convenient way where there is needs to consider environmental pollution noise and external dangers to the public. However, it makes of use water sprinkling, sawing together with thermic lane. The principal purpose of water jetting is reducing the incident of fire outbreak and minimizing air pollution by the dust in production. Thermic lane is preferable when there is the need to destroy the reinforcement steel that is in place in the building or eliminating vibrations or dust production. Selective demolition is cost effective as it saves asset that can be underutilization again in a different project plan. The principal purpose of this method is keeping structures and damaging them would result in a loss to the owner of the building. In this case, the building is under demolition through implosion method due to the size and the location. The implosion uses the pressure inside the building and the pressure outside the building it is the collision between the inward pressure and the outward pressure. The pressure outside the building should be greater that the inward pressure to ensure that the building collapses inwardly eliminating the possible danger throwing structures to the nearby people or buildings. However, pressure is not the only factor in place; the method weakens the major supporting points and due to the higher force of gravity, the holding structures fail to support the significant weight hence falling significantly. Before the implosion process kicks off, the following will be ensured to be in the place i. Fire brigades ii. Load carriers iii. Medical team iv. Crew protective gear v. Working site to trigger the implosion vi. Perimeter wall vii. Police officials viii. Caution signs set in place ix. Enough explosives x. Cranes xi. An alternative route for the public The fire brigades will be responsible for jetting water around the implosion site after the building is demolished. The principal purpose of that is to eliminate the dust that will have been produced to avoid air pollution, which would be against the construction laws. The load carriers will be in charge of carrying the concrete materials after demolishing the building. The purpose of carrying the concrete materials and all other materials will be to create room for the reconstruction. The protective gear for the crew will protect them from the chemicals and dust pollution. This is important in ensuring the health standards is in place, which is in law with the construction regulations. On the other hand, the working site for triggering the implosion is a safety precaution in avoiding any fatal incident to the crew staff. The crew staff should maintain their safety as there is no one that is responsible for their health other than themselves. Any loss of a crew would destabilize the process since each crew staff is in charge of a specific sector in the implosion activity. The specifications of duties by the crew enable high level of accuracy as each staff has a particular single obligation to carry out. The perimeter wall acts as a caution to the public ensuring that no unauthorized personnel has the authority to go beyond the wall. It creates awareness that a dangerous activity is at motion hence no person should be within the perimeter wall. The caution signs provide a direct message to the business that is in place. It also assists in ensuring that the public understand the dangers in place if any violation of the signs occurs; hence, the public will take precaution obeying the set directions. The police officials have the responsibility of regulating movement near the implosion site by the public who do not read the caution signs but not arresting them. The presence of the police will create attention to the public for the major reason of deployment of police in the site. However, the security will be responsible for explaining the dangers of implosion and providing a solution as well. The principal purpose of checking if there are enough explosives is to make sure that the building utilizes exact number of the explosives to avoid any extreme explosion. It however, assists in ensuring that the building comes down with a single explosion process, which in turn simplifies the entire process of repeating the implosion procedure. The medical team will ensure that any victims that are affected by the implosion are attended to and receive the necessary medical procedures. However, they are to take blood samples of the public that are within a particular range to search if there would be any chemical infection or any medical problem because of the implosion. The cranes will dig up the demolished materials of the building to find any asset that is in condition of being recycled for the reconstruction. There are several dangers due to the use of building implosion and some of the dangers include Air pollution Air pollution is the major impact due to the use of the method as dust is in production significantly during the collapse. The dust in production may act as a major problem to the public inconveniencing locomotion of people freely. However, the possibility of having individuals with dust allergy serves as a deadly danger to the experts due to any fatal reactions of the individuals Noise pollution It is the process of producing harmful or dangerous noise to the public during working hours mainly. The explosives produce great noise due to the chemical reactions that take place to provide the necessary energy to deform support structures. After the support structures are in deformation, the building is likely to come down producing noise or a loud bang Loss of valuable structures The explosion is likely to destroy all assets that can be under salvage to be in utilization for the reconstruction process after the demolition process. The purpose of the implosion process is to bring down the structure but not to save any material. It is unlikely since it increases the cost of purchasing new structures that are to be used in rebuilding the building. The structures that would have been in salvage would have been restructured to different forms that would be useful at later stages Congestion of people The congestion will be due to establishment of the perimeter caution to be observed hence providing an alternative route that will have to accommodate the personnel and vehicles that will be using the route after diversion. The process of demolition will take place after a series of actions take place; i. Survey of the building The crew will first take note of the strategic points to place the explosives to avoid using excess explosives. The strategic support points act as the major weakening points to speed up the process of demolishing the structure. However, the purpose of surveying the building is to make sure that there are enough explosives that are in preparation to avoid the incident of deficit of the explosive devices that are brought along by the crew. ii. Preparing an alternative way for public The demolition process should not in any way inconvenience the public from carrying out their daily duties. However, it is against the law to inconvenience the public and hence the crew will identify the possible routes that both vehicles and public will use during the demolition process. It ensures that there is no exposure of danger to the public, dangers of exposure to dangerous chemicals, dust pollution and accidents from the falling parts of the building. iii. Training of the crew The crew will have to undergo the necessary training process to be sure and aware of the specific actions to carry out. However, specialization of the crew is vital to ensure that each person provides the best output to avoid mistakes that would have fatal outcomes to the crew and public as well. During the training process, the crew will agree on the possible ways of carrying out the process highlighting the potential dangers that the crew will have to contaminate avoiding exposure to dangerous materials and chemicals. iv. Setting of perimeter wall An important process is in accordance with the law to avoid exposing the public to harmful conditions during the demolition process. The crew will establish the dimensions around the building that will guarantee the public of the maximum distance that any parts of the buildings can fall. After determining the measurements, a perimeter wall will be in place set by the crew that will act as a safety caution. v. Establishing the working area The crew will have to identify a strategic position that will act as an operation area for observing the impact of the explosion to avoid exposing the crew to a fatal condition. The working site will serve as the detonation point for the explosives that will be done by the crew at the set time. The set time is important to make sure that the explosives trigger at the same time bringing the building down at almost the same time. It avoids the possibility of some of the particular support parts not breaking causing failure of the building to come down. vi. Establishing the medical team position The law requires there be an emergency team that will respond immediately to any accidents to occur due to the demolition of the building. The crew hence will have to make sure that the medical team is set to respond to tragedies. However, the medical staff will take blood tests from the crew to check if any personnel contain any infections due to the implosion. Due to the air pollution that is likely to happen, fire brigades would be in place to jet water around the building after collapses to eliminate dust pollution immediately. However, the medical team will be in place to carry any victims that get any injuries. In addition, the medical staff has the responsibility of taking blood samples from any nearby members of the public to ensure that the chemical let out by the explosives did not affect the public. In cases of chemical infection, a separate medical team carry’s the victims immediately to a medical facility that has the capacity of treating the infection to avoid any fatal results. Police will be present to make the process effective and ensure that the caution signs put in place by the implosion crew are followed to the letter. However, the police officials will be in charge of ensuring that the public do not reach the area of demolition after the process is complete. The main purpose of regulating the movement to the demolition site is to avoid exposure of the public to dust and the dangerous chemicals in emission by the explosives. The chemicals have enormous implications one of the implications being paralysis of a person or death. The crew will have protective gear that they are to wear during planting of the explosives in case the explosives go off during the planting process. The gear also serves the purpose of ensuring chemicals used to make the explosives do not affect the crew. In addition, the crew will have the protective gear during the implosion and after the implosion process. It ensures that, during the inspection period, the inspecting crew is not exposed to the chemicals and dust. The crew will be inspecting to obtain any asset that can be of value to be used again during the rebuilding process. The crew will use the crane to overturn the structures to identify any useful asset as well as clearing the area in preparation for the reconstruction. Load carriers will be present to carry the concrete materials out of the site to clear the place for the reconstruction. The cranes will load the carriers until all the concrete waste materials are moved out of the site. After the implosion, the rebuilding process will require the perimeter wall, the cranes, protective gear, materials to be used in rebuilding process and the medical staff. The boundary wall will ensure that the public is protected from any falling materials during the reconstruction process. It however, enlighten the public in the ongoing building process hence avoiding the region due to the possibility of having falling building materials that can cause fatal damages. The cranes will be taking materials of construction to high levels that essential human effort would be tiresome ; hence, the crane simplifies taking building materials. The protective gear will be protecting the constructors from hurting themselves and in case of falling no damages, or no huge damages will occur. The medical staff is critical to ensuring that while rebuilding any accidents that occur are dealt with immediately avoiding loss of life or worsening the already occurred damage to the victim. Minimum noise will be ensured to avoid violating the law since noise pollution inconveniences public performance of their duties. Air pollution will be at regulation to avoid breaking the construction laws or regulations. There are different types of demolition depending on the size of the building, cautions to observe, requirements such as if there is the need to save any asset from the building such as, steel or steel. Building implosion serves as the best type of demolition to big structures; it uses the law of pressure, gravity as well as weight. This law assumes that after weakening support points, the Centre of gravity force attracts the building downwards ensuring that the support joints can no longer hold the weight of the building. Dangers involved in building implosion include air pollution, noise pollution and inconvenience to public. Specific procedures have to be carried out before implosion for accuracy purposes and to act according to the OSHA construction procedures. Work cited "Latest News." City Environmental Services News.
