How is Commercial Demolition Done?
Commercial demolition is the complete or partial removal of unwanted commercial structures, such as hotels, malls, office buildings, and other properties alike. When you think about demolition, you might think it is simply knocking walls over and getting rid of the structure easily and quickly. However, there is a lot that goes into preparing an area for demolition. Additionally, many provinces require permits to demolish any structure. This is because it is a very dangerous job that requires safety measures to be taken care of before even starting the demolition process.
Since most commercial structures are much larger than residential buildings, there are special requirements for demolishing such structures. Additionally, commercial buildings might be located in high-traffic areas, which also require special safety measures to take place.
Before Starting the Demolition
It is of the utmost importance that the demolition of the commercial structure is done in a safe and stable condition, to prevent an unexpected collapse of part or all of the structure. The following needs to be taken into consideration: stability of the structure, position, depth and type of basements, wells, and underground storage, public access, boundary walls, and adjoining properties and structures.
Every local government is different when it comes to permits that are required to start the commercial demolition process. Calgary, for instance, requires a permit whenever you are demolishing or moving a building from a site. It can also include partial building demolition and reducing a building to its foundation and rebuilding. The process is fairly simple, but it needs to be thorough and accurate.
Before applying for a demolition permit, the building needs to be inspected by an asbestos removal company. If there is a sign of asbestos in the building, you need to have it professionally removed, as well as proof that the building has no asbestos. You must also submit a public tree disclosure statement. Additionally, there should be a construction sign with contact information outside the construction area.
Once you have done all the pre-requisites, you can prepare your application and submit it. This application process can be done online or in person. After the application has been submitted, you will book an inspection to get the permit approved.
Why Do You Need Asbestos Removal?
Asbestos is a naturally occurring mineral made up of heat-resistant fibers. The mineral is extremely toxic when its dust is inhaled or digested, in which the fibers can become permanently trapped in the body. Over the years, trapped asbestos can cause inflammation, and scarring, and lead to genetic damage. Additionally, exposure to the mineral can cause cancer and other health conditions.
Because of its dangerous qualities, asbestos should only be removed with proper professional equipment. However, this process can take time. Therefore, if professionals find asbestos in the building, plan for a week or more to get the mineral removed.
Commercial Demolition Checklist
Before starting the demolition process, a professional demolition company will make sure that the following checklist is taken care of:
- Work area is secured and considered an exclusion zone.
- Adequate public safety and access to roads and walkways.
- Fire risks are observed, and preventative plans are placed.
- Remove all utility services.
- Set up debris systems to ensure any debris is removed to prevent buildup.
- Ensure operators demolish floor by floor.
- Brace walls and floors.
- Remove ornamental stonework.
- Conduct a thorough inspection of safety gear, machinery, and equipment.
- Ensure operators are well informed, trained, knowledgeable, and supervised.
- Communicate demolition plans to all personnel.
How Long Does It Take?
Once the site is prepared and the essential demolition permissions are good to go, it will take about three to seven days to complete a commercial demolition. Of course, it all depends on the location and the size of the structure. For instance, it can take weeks to demolish a large building in the heart of the city.
How Much Does It Cost?
In Canada, the average cost of commercial demolition is around $5 to $10 per square foot. All in all, the larger the structure, the more expensive the demolition will be. However, size is not the only thing that comes to play when it comes to the cost of commercial demolition. The location of the structure and permits are also factors that can come to play in commercial demolition. Although demolition is an inexpensive profession in the construction industry, its dangers can increase costs. This dangerous job requires clear safety guidelines and the utmost care to follow them.
Where Does Waste Go After the Demolition?
After a building is demolished, there will be a lot of waste. This is another reason why it should be done by professionals who will know how to properly dispose of the waste. Additionally, these companies know how to properly separate and recover materials to cut costs and natural resource use.
Here are a few examples of where waste goes:
- Concrete is often crushed into gravel, which is used in new construction projects.
- Steel and scrap metal get processed and recycled to create new materials.
- Interior doors and beams are created out of decent condition scrap wood after the demolition.
- Sinks and toilets from the demolished building, if still in good condition, are taken to a salvage company. If they are not in good condition, the porcelain sinks and toilets are recycled with concrete, and stainless-steel fixtures are recycled with scrap metal.
