In today’s environmentally conscious world, selective demolition is gaining popularity. Rather than demolishing the entire structure in one fell swoop, this method involves removing specific sections of the structure while leaving the structure intact. It’s an excellent choice for building remodels, upgrades, and extensions where recycling and reusing materials are desired to minimise the environmental impact of the demolition.
As with any type of demolition, this method entails a thorough examination of the structure of the building, the removal of hazardous materials, and the determination of recyclable materials. The following are the steps involved in a selective demolition procedure:
- Prepare the location
Mechanics, electricians, and plumbers turn off the electricity, turn off HVAC systems, and plug open piping. Additionally, crew members install a temporary lighting system and a trash chute to facilitate the sorting of recyclable materials.
- Remove non-structural elements
Labor forces destroy the structure’s architectural, mechanical, and electrical components, leaving only the shell.
- Remove materials and reinforce the structure
Additionally, shoring and temporary support were added to the structure. External sections of the building are demolished by removing floor beams, load-bearing walls, columns, and floor slabs.
- Sort debris
When the old building has been demolished and the materials can be reused, recycled, sold, or given away, the team then starts to build again.
What is the Process of Pre-Demolition?
Before a selective demolition in Geelong can be carried out, several factors must be considered. Each demolition project is unique, but typically includes the following steps:
- Building survey
Experts examine a building’s various characteristics, including its materials, intended use, construction method, condition, drainage conditions, traffic conditions, and compliance with applicable building codes and neighbouring communities. A study of these parameters will aid in determining the most effective demolition method.
- Hazardous material removal
Before the building is demolished, a team of experts is called in to remove dangerous materials, such as asbestos minerals, radioactive substances, flammable materials, and petroleum contamination.
- Selecting the demolition plan
Experts create a detailed plan outlining the scope of the demolition, the method by which it will be carried out, the equipment that will be used, and the amount of debris that will need to be cleaned up.
- Safety measures
Site personnel, supervisors, operators, and engineers are informed of potential hazards such as flammable materials and noise and dust exposure. Additionally, the demolition company must obtain the necessary permits.
The next step is to determine the safest and most cost-effective demolition method. Not all demolitions end in explosions; methods range from lethal blasts to non-explosive piecemeal removals. Implosions, excavators, wrecking balls, bulldozers, and selective demolition are just a few examples.
When a building reaches the end of its useful life, it must be demolished in an efficient and non-hazardous manner. To some, witnessing a demolition is awe-inspiring. Demolitions are critical to our communities’ growth and revitalization, and they are constantly evolving to be more cost-effective, safe, and environmentally friendly. However, successful demolition requires a high level of expertise and precision.
