The Safe Design and Execution of Demolition 2INTRODUCTIONAny job connected to the demolition of a building is known as work of construction under the regulations of work health and safety. When performing the demolition work, the necessities connected to construction work must be followed. Demolition means to dismantle a structure of load bearing or that is related to the physical integrity of the structure after the life ofserviceability by controlled and pre-planned methods but does not include the false work designed to provide the support, containment or access during construction. Also, it does not include the removal of telecommunication poles, power and lights. A structure is any constructedthing, whether movable or fixed, permanent or temporary and comprises the storage tanks, silos, chimney stacks, towers, sheds and buildings[CITATION Bui10 \l 1033 ]. The codes give the guidance on how risks associated with the demolition work can be managed and follows the systematic process such as; identifying the hazards, assessing the associated risks with the identified hazards if necessary, implementing the measures of control and reviewing and maintain the effectiveness of the control measures. Demolition of a house andthe structures are needed for many reasons, for example, the building design has a lifespan known as the design life. The building is constructed considering the lifespan and when the design life is over, the building is not safe for the neighboring buildings and living[ CITATION Chi141 \l 1033 ]. Old structures can be replaced by the new ones, the building can also lose its stability or, might have a damage, some of them are also demolished to construct the bigger ones.The top-down way is the self-descending grid structure made of the steel and work according to the hydraulic principle controlled by the systems automated. It assembled on the ground and its component of load bearing are mounted on top of the high rise building[CITATION
The Safe Design and Execution of Demolition 3Ric13 \l 1033 ]. The shape of the top way system modular can be adapted to the shape of any high rise building. it enables the work demolition and as the work proceeds, the platform of top way system, descends in the controlled manner and position on the floor down, the skyscraper is demolished floor by floor until the level of the ground is reached.Figure 1: Demolition processThe risk management processIdentifying the hazardsIdentification of the risk that is connected with the demolition work are the first things to do in the management process, examples include; unplanned collapse of the structure, falls from one level to another, objects that falls, the location of underground and above the essential services such as supply of water, gas, chemicals, telecommunication and electricity, exposure of the dangerous chemicals that may be available in the materials demolished or the ground where the work or demolition is to take place, dangerous noise from the plants and explosives used in the demolition and the building’s proximity being dismantled to other structures[CITATION Dan14 \l 1033 ].
The Safe Design and Execution of Demolition 4Figure 2 above shows the workplace where the demolition has to take place and the signs and posters are put to shows the people around that they should keep away because the site is dangerousAssessing the risksUnder the work health and safety regulation, the management of the risk is not important for the dismantle work but it is needed for the exact situation. For examples when dealing with explosives or asbestos[ CITATION Mik13 \l 1033 ]. In many cases, the assessment of risks will help in knowing the measures of control to be applied. It will enable the identification of workers whoare at the risks of coverage, regulate the processes and causes that are the root cause of the risks, identify the type of measures to be applied and check the efficiency of the obtainable measures of control. when doing the risks assessment there are some of the things that should be considered such as; the structural integrity of the building to be demolished, the demolition methods and its sequencing, work schedule, the workplace layout, the equipment and plants to beused exposure that it might cause UV or noise, number of the involved people and condition of the local weather[ CITATION Joh131 \l 1033 ].
