Show answer & explanationAnswer & explanation
Correct answer: D. A detailed demolition plan submitted to and approved by the building official.
IBC 3303.1 mandates that before demolition of a building or structure, a demolition plan shall be submitted to and approved by the building official. This plan outlines the procedures and safeguards for the demolition process.
Why the other options are wrong
- A. Temporary shoring and bracing are part of the *execution* of the demolition plan, not a prerequisite for *beginning* structural demolition; the plan must be approved first.
- B. While an asbestos survey is often required, it's typically an environmental regulation, not specifically a building code requirement for the demolition process itself, though it may be a prerequisite for permitting.
- C. Notification to the fire department may be required by local ordinances or for specific hazards, but it's not the universal *building code* prerequisite for *structural* demolition.
Demolition Plan Requirement
Before structural demolition of a building or structure can commence, a comprehensive demolition plan must be submitted to and approved by the building official, detailing the procedures and safety measures.
- Mandated by IBC 3303.1 for all structural demolition.
- Ensures worker and public safety.
- Covers sequence of operations, equipment, and protection measures.
- Approval is a prerequisite for obtaining a demolition permit.
Memory trick: Before the wrecking ball swings, a plan the official brings.
