Compliance with the 2024 Ontario Building Code (OBC) is critical for site safety and legal occupancy. At empcontracting.ca Inc. your construction contractor in London, Ontario, we ensure every project adheres to the rigorous standards set out in Division C, Part 1 regarding site protection and prescribed notices.
Site Safety and Physical Barrier Requirements
The OBC mandates that active construction sites implement temporary or permanent physical barriers to protect occupied areas from falling debris, tools, and machinery. This is a vital requirement for mixed-use developments or phased renovations where parts of a building remain in use during construction.
Fall Protection and Horizontal Safety Nets
According to Clause 1.3.5.1.(11), safety nets and horizontal fall protection systems must extend no less than 3 meters from the face of the building. These systems are mandatory for exterior construction on unenclosed storeys and must be located immediately below the active construction floor to mitigate risks of falling materials.
Fire Department Approvals and Professional Reviews
Before any permit is issued or occupancy is granted, specific administrative hurdles must be cleared. If a municipality assigns fire safety enforcement to the Fire Chief, the Chief Building Official will not issue a permit until the fire department has approved the drawings. Furthermore, a professional engineer or architect must review the construction prior to occupancy to certify that the building is safe for its intended use.
Prescribed Inspection Notices under Article 1.3.5.1.
Project success depends on timely communication with building officials. Permit holders are legally required to provide notice at several key milestones to allow for mandatory inspections:
Critical Notification Milestones
- Footings: Readiness to construct footings and substantial completion of foundations prior to backfilling.
- Structural Framing: Completion of framing and rough-in for HVAC and piping systems.
- Building Envelope: Completion of insulation, vapour barriers, and air barrier systems to ensure thermal efficiency and moisture control.
