Sequences
Before any demolition take place planning is needed by the local authority. The survey of the site is need to ensure the condition of the existing building, it is important for further checks carried out in case of any adjacent building; it is important to consider to inspect the site before any works take places and examine the type of plant and machinery whether this machinery are allowed on the site that ground condition may not support heavy machinery. It is important to note that the site is adjacent to the reservoir. At present there are many issues with the existing building such as water damages, issue of walls, windows, gutters and downpipes and drainage problems.
It is helpful to reduce outdoor and indoor air quality problem from the construction. It is also to notice that renovation process is helpful to maintain the comfort for the well-being of the construction workers and occupants.
Sustainable architecture seeks to minimise the negative environmental impact of the building by enhancing efficiency and moderation in the use of materials, energy, and development space, most simple or ecological design material & resource. It is important to find sitting of cellars and basements, walls note any structural damage and cracks and before any work starts proper check is needed before any structural is dismantling. It is essential to verify the age of building or if the structure is on preservation list. Due to heavy flooding the building needs Inspection, to verify if any floor in danger, and what type of ground are the building, soil and particularly clay condition. The existing public services to locate drains, gas, water, telephones lines, electricity, and etc arrangement will be needed to diversion or removal or whether remain for protection. Also permission is required from the local authority in case of road closure and traffic diversion
Building regulations, building act, CDM regulation, according to the building act 1984, demolition is controlled and it should be given the prior notice to the local authority. It is the duty of the local authority that in the notice clearly specification and condition must be met. The procedure of the demolition meet the condition of the construction design and management regulation 1994 and health and safety plan should be prepared. Demolition waste used steel, concrete, wood glass and metals and energy consumption for demolition. Extreme noise can be dropping by use silencer machinery’s, jackhammer, and compressors against noise and minimise the number of people working on site. The use of water to control dust which is helpful to cool down dust level and to minimise the release of dust into environment and control emissions and disturbance of neighbouring properties. Therefore, under the CDM regulation it is important to assess the environmental impact and fossil fuels is used and air pollution emission related with demolition waste. Under the demolition, CO2 is reducing and it is not stated that there is no particular areas that is achieving air quality standards. There is large urban areas with extreme traffic and areas influenced through emission from heavy and powerful sources and air pollution levels is more than the predetermined by the EPA to save the health of human and welfare. Demolition method is done manually, as per CDM regulation it is important to assess to avoid the injuries.
It is important to help to complete demolition by reaching the target of nil landfill. The waste exchange is helping to reduce the reliance on co2 producing fossil fuels for the future.
From a complete lifecycle assessment perspective, construction, operation and demolition and reuse of building involve a chain of economic activities which is provided the goods and services compulsory to build, sustain and in due course convert assets.
Zero landfill is helpful for the environment because all the construction waste to be 100% recycle and reuse which is more eco-friendly for the organic components. It is to be needed to conserve the existing wood natural areas also repair damage areas on the way to provided good environment and support diversity.
According to the new technologies are constantly developed to complement the green structures. The objectives of the green buildings is more eco-friendly and avoid all impact which is harmful to the environment. It is important to use efficiently energy, water and other resources. It is to be protecting occupant health and improving employee productivity. It is also important to reduce waste and pollution to make environment eco-friendly.
The Demolition
processBefore Demolishing of any structure the site and the building must be investigated according with AS2601, Demolition work plan must be prepared under AS2601 which describe the Demolition method and Demolition techniques, which one of the basis think of investigation. One of the most factors is take account in the location all utility services such as Gas, Water supply pipes and communication cables. After completion of safety plan, the demolition contractor can start demolition work, no demolition work commence until the safety plans arrives.
The safety plan must specially address:
Risk management process
Site investigation report
Training to be provided to workers
Emergency procedures
Emergency procedures under Health & Safety
In the case of serious injury the demolition contractor must provide for first aid require and other medical attention. The emergency procedures addressed in the demolition safety plan. All work should be in the contact, site sign and contact number of emergency also need to display.
Reduce procedures were concern following area:
Working at heigh
Spaces of scaffold
Hazards substances
Before starting Demolition work should avoid risk arising from any potential explosive, the hazards must identified assumed and controlled, with using Code of Practise for control of work place hazards.
Before starting Demolition the site should be examine under risk
Fire and explosion
Toxic, radio activity
Dust control
Avoid asbestos
Reduce noise
