Demolition Work Supervisor

Core Role Definition

The Demolition Work Supervisor is responsible for planning, coordinating, and overseeing all phases of a demolition project—from pre-demolition surveys to final site clearance. They ensure work is completed safely, on schedule, within budget, and in full compliance with OSHA (or local HSE) regulations, environmental laws, and structural engineering requirements.

Primary Responsibilities (By Category)

1. Pre-Demolition Planning & Engineering

• Conduct engineering surveys: Identify structural systems, adjacent building vulnerabilities, utility connections, and potential collapse patterns.

• Develop sequence of operations: Determine top-down vs. selective demolition, load path management, and shoring/bracing requirements.

• Utility isolation: Coordinate with utility companies to cap electric, gas, water, sewer, and communications lines.

• Hazardous materials inspection: Ensure asbestos, lead paint, PCBs, mercury, or mold are abated before mechanical demolition begins.

• Permit acquisition: Obtain necessary demolition permits, noise variances, street closure approvals, and air quality waivers.

2. Safety Management (Most Critical)

• Site-specific safety plan: Create and enforce a demolition safety plan including fall protection, dust control, and emergency evacuation.

• Personal protective equipment (PPE): Enforce hard hats, high-visibility vests, steel-toed boots, respirators (P100 or supplied air), hearing protection, and cut-resistant gloves.

• Exposure monitoring: Monitor airborne silica, asbestos fibers, and noise levels daily.

• Fire prevention: Ensure fire extinguishers, water supply, and hot work permits are in place—demolition sparks are a major fire risk.

• Structural integrity checks: Inspect partially demolished structures before each shift for cracks, leaning walls, or unstable floors.

3. Equipment & Tool Oversight

• Heavy equipment operation oversight: Manage excavators (with shears, crushers, or hammers), high-reach excavators (40–100 ft), skid steers, and cranes.

• Tool inspections: Verify that handheld tools (breaker guns, concrete saws, torches) are in safe working order.

• Lift planning: Supervise all crane lifts of heavy debris or steel beams; ensure rigging is certified.

• Dust suppression: Operate water sprayers, misting cannons, or foam systems to control visible emissions.

4. Work Execution & Monitoring

• Sequence enforcement: Ensure no worker enters a zone beneath active demolition or within the “danger zone” (1.5x height of structure).

• Selective demolition: Guide crews on removing non-structural elements before structural members.

• Debris management: Oversee sorting of concrete, rebar, wood, metals, and hazardous waste for recycling or disposal.

• Building collapse supervision: For implosion or mechanical collapse, enforce exclusion zones, warning signals, and post-collapse dust settlement periods.

5. Regulatory & Documentation Compliance

• OSHA (or local HSE) Subpart T – Demolition: Comply with 29 CFR 1926.850 (demolition specific).
  Example: Require engineering survey before any demolition begins.

• Recordkeeping: Maintain daily logs of equipment inspections, safety meetings, air monitoring, and near-miss incidents.

• Waste manifests: Sign off on hazardous waste disposal manifests (asbestos, lead-contaminated debris).

• Incident reporting: Report any injury, structural failure, or unplanned utility strike within required timeframes.

6. Team Leadership & Communication

• Daily toolbox talks: Conduct 10–15 minute safety briefings covering the specific hazards of that day’s demolition tasks.

• Signal person duties: Act as or designate a qualified signal person for crane and excavator operations.

• Coordination with other trades: Liaise with abatement contractors, structural engineers, utility companies, and local fire departments.

• Stop work authority: Empower all crew members—and exercise personally—to halt any unsafe demolition activity immediately.
