The Process of Demolition

Feb 16, 2021 | Resources

There’s more to the commercial demolition process than knocking everything down with hammers and wrecking balls. There’s no one-size-fits-all method, either. Every structure has different challenges and external factors that need to be taken into account, so experts need to be knowledgeable and well-trained in the process of demolition.


Surveying the Building


Demolition experts conduct a building survey and a structural survey, examining the various factors to help them determine the safest and most effective method of demolition. They consider the original construction of the building, the materials used, the current condition, building codes, drainage routes, shared walls, and how the demolition may affect people living nearby.


Removing Hazardous Material


Specialists are called in to remove dangerous materials before demolition starts. This includes asbestos minerals, radioactive substances, and flammable materials and liquids.


Developing a Demolition Plan


Using the information gathered during the survey, experts form a comprehensive plan to demolish the building, which includes things like:

  • Building location
  • Distances from surrounding road, buildings, and other structures
  • Safety measures to protect and keep out the public
  • Demolition method
  • Demolition waste disposal or recycling plan


Ensuring Safety


After ensuring the demolition crew has the proper permits, everyone on site, from the machinery operators to engineers to site supervisors, is briefed on the demolition plan process, as well as the potential hazards, like dust and noise. Everyone is equipped with the PPE needed to keep them safe, and emergency plans are reviewed.


Tearing it Down


After the preparation stages, much of the process depends on the method of demolition method chosen in the plan. At Landwehr Construction, we specialize in excavator demolition, a non-explosive method. Using tools, like shears, crushers, and hydraulic hammers, which attach to the arm of the excavator, the building is demolished from the top down. On the ground, workers with sledgehammers break down large chunks of material so the rubble can be more easily transported.
