As we all know that every building and structure has its own lifespan which is commonly known as design life. Generally, a structure is considered to have a life span of 80 to 100 years and when this life is over, it is not safe to use those structures and buildings. Commercial demolition is required for various reasons, and besides the buildings being old, there are various other reasons for commercial demolition such as the structure has lost its stability or has any structural damage or maybe a small structure is demolished to create a bigger structure.
Commercial Demolition Process
There are different steps that are required in the process of commercial demolition which are:
a). Building Surveying
Following pointers are to keep in mind when processing for building surveying:
- Types of construction material used
- How the building is/was used prior and present during demolition
- The presence of hazardous materials, materials coming from toxic chemicals, wastewater and radioactive materials.
- The sensitivity of neighborhood with respect to the impact of commercial demolition contractors such as noise and vibrations.
- Shared facilities with nearby buildings
b). Structural Surveying
Following pointers are to keep in mind when processing for structural surveying:
- Method of construction used for creating the structure
- Condition of the building
- Structural system that is used in the design
- Structural position of the underground tanks, basement, and underground vaults.
- Removal of Hazardous Materials
Hazardous material such as petroleum contamination, asbestos materials and radioactive metals if found during the investigation must be removed. To go through this process, a team of specialized people is called for the removal of hazardous materials from the site before commencing commercial demolition.
- Preparation of A detailed plan before commencing the commercial demolition plan is made which consists of the following points:
- Time required for the entire process of commercial demolition
- The location of the building that is to be demolished
- The structural support systems of the building to be demolished
- A plan that consists of the details of the procedure for demolition
- A plan that shows the precautionary measures for the protection of the demolition team and the general public.
- The distances from the structure to be demolished to its nearby buildings and street
- Safety Measures
Before the demolition begins, all the workers, engineers and site supervisors are thoroughly briefed about the process of demolition and the potential hazards. All goods that are flammable are to be removed from the site and all flammable materials such as fuels; timber and wood etc. are kept in proper storage facilities. Furthermore, due to this process, many problems are faced by workers such as chemical exposure, dust exposure ventilation, heat stress, medical and first aid facilities, noise exposure, and sanitation issues. To overcome the above mentioned issues, safety measures are to be taken.
