How to Prepare for Demolition Excavation

Contrary to popular belief, demolition is not just about blowing stuff up and watching everything go down. In fact, non-implosive types of demolition can also be done depending on your situation. Demolition is a complicated process that requires careful planning. Since you’ll be taking down existing structures to prepare for new residential or industrial projects, it’s only reasonable that you take the necessary precautions. Proper preparation is essential to ensure safety, efficiency, and compliance with regulations.

In this blog, we will walk you through what demolition is all about and the steps you must take if you’re going down this road.

What is Demolition?

What is Demolition

Demolition is the process of removing and discarding any kind of existing structure, whether it is an old building, huge wall or equipment. It’s not necessarily done to facilitate construction, but rather, demolition is enforced because:

  • The building is no longer safe to occupy,
  • it has outlived its usefulness and requires too many repairs to certain areas or
  • the owner intends to sell the land once it is cleared

If a building or structure isn’t demolished when it needs to be, it could be hazardous for the people who live there or are nearby. Careful planning is required to ensure the demolition process is done safely.

Demolition Methods

Demolition Methods

Many factors must be considered when preparing to demolish an existing structure. These include the construction, location, materials, strength, and potential dangers that could result from a faulty demolition. To ensure a safe demolition procedure, you must decide on the best demolition method for your case before moving forward with your plan.

There are two main types of demolition methods:

Non-Explosive Method

The non-explosive method makes use of both mechanical and manual equipment. It works best for tearing down houses and other medium-to small-sized buildings. This procedure involves the use of:

  • Sledgehammers
  • Bulldozers
  • Wrecking balls
  • Standard and high-reach excavators

Explosive Method

The explosive method involves detonating explosives to destroy the building’s structural supports and cause it to collapse. It is best suited for dismantling a building or structure of great height. There are two ways to do this:

  • Falling like a tree (the building is demolished and made to fall sideways)
  • Falling into its own footprint (i.e., the building is imploded and collapses on itself)

The Demolition Process

As with anything else in life, planning is an essential part of any endeavour. Planning well can save you a whole lot of trouble and stress down the road. In the construction industry, things might go awry if proper planning and safety protocols are not followed. As such, here are some of the steps to be undertaken to ensure a safe and efficient demolition excavation process:

Research and Compliance

Start with doing a bit of research first. You don’t want to go into the project without any piece of critical information. Familiarise yourself with local and state regulations governing demolition and excavation in your area. Regulations may vary, so it’s crucial to understand the specific requirements in your area.

Hire Professionals

Unless you own an operated business in construction or civil works, it is not advisable to do demolition and excavation projects on your own. You need to hire a licensed demolition contractor with enough experience. Make sure that you get a highly experienced team to work with you, as this is a dangerous procedure to be accomplished. You need expertise when it comes to this endeavour. Don’t just do it on your own.

Conduct a Site Assessment

Before initiating any project, it’s essential to understand your existing structure better. Conduct a thorough site assessment. Identify existing structures, utilities, and potential hazards. Obtain accurate blueprints or as-built drawings to understand the site’s layout and any hidden challenges. This assessment will serve as the foundation for developing a detailed demolition plan.

Obtain Necessary Permits

Demolition and excavation require various permits from local authorities. Obtain the necessary approvals to ensure compliance with safety and environmental regulations. This may include permits for demolition, excavation, dust control, and waste disposal. Please ensure proper permits are acquired to avoid hefty fines, costly delays and legal issues.

Develop a Demolition Plan

Talk with your hired contractor regarding crafting a demolition plan. It would be best to create a comprehensive plan outlining the sequence of activities, safety measures, and environmental considerations. The plan should detail the demolition methods, equipment to be used, and waste disposal procedures.

Dust Control and Asbestos Removal

Since you’ll be demolishing a building, there might be unintended consequences when it all blows up. Before starting the process, identify and remove any hazardous materials, such as asbestos, lead-based paint, or other contaminants. It’s also important to note that demolition generates dust, which can pose health and environmental hazards. Implement effective dust control measures to minimise airborne particles and comply with air quality regulations. Hiring licensed and fully insured professionals to remove and dispose of these materials is crucial to prevent health risks and environmental damage.

Disconnect Utilities

Coordinate with utility providers to disconnect gas, water, electricity, and other services before demolition begins. This step is essential to ensure the safety of workers and prevent damage to utilities during excavation. Clearly mark the location of utility lines to avoid accidental damage.

Reuse or Salvage Old Materials

Before you call in the experts to do their job, assess if any materials can be salvaged and reused. Salvaging materials not only contributes to sustainability but can also be cost-effective. Prioritise the recovery of valuable materials like bricks, lumber, or metal and plan for their proper storage and transport.

Establish Safety Protocols

Safety should be a top priority during demolition excavation. Develop and enforce strict safety protocols, including the use of personal protective equipment (PPE), fall protection measures, and emergency response plans.
