During underpinning excavation, multiple technical and safety precautions are taken to ensure the home's stability and a secure worksite. This type of work requires close coordination between workers, engineers, and site managers.
Key precautions include:
- Alternate section excavation: to prevent settlement or loss of support.
- Temporary structural support: jacks, beams, and shoring are used to stabilize the house.
- Preliminary geotechnical analysis: to understand soil composition and adapt excavation methods.
- Engineered work plan: each phase is designed and approved by a structural engineer.
- Daily monitoring: constant checks on levels, support integrity, and progress.
- Site safety measures: restricted access, clear signage, and protective gear for workers.
These precautions ensure that the excavation is carried out safely—even beneath an existing structure. For more information on how the work is performed, contact Heneault Gosselin.
