Silent Building Demolition Services

Onyx Engineering offers Silent Building Demolition Services designed for sensitive occupancies, heritage sites, and urban environments where noise and vibration must be minimized. Our approach combines low-noise equipment, vibration-control techniques, and strategic sequencing to deliver safe, compliant demolition with minimal disruption to occupants and surrounding communities.

Why choose Onyx for silent demolition

• Noise and vibration minimization: Specialized equipment and operating procedures reduce sound levels and ground-borne vibration.
• Community and site-friendly: Prioritizes area quietness, dust containment, and worker and public safety during daytime and restricted-hours work.
• Safety and compliance: ISO 45001:2018 health & safety and ISO 9001:2015 quality management, with site-specific RAMS, permits, and on-site supervision.
• Precision and control: Detailed planning ensures controlled knockdown sequences, preserving facades or non-targeted structures when required.
• Versatility: Suitable for vintage and sensitive structures, urban cores, and occupied facilities with strict access controls.

Our silent demolition capabilities

• Interior selective demolition: Removing non-structural elements with minimal noise and dust.
• Facade preservation and careful envelope removal: Reducing impact to historic or adjacent façades.
• Lightweight non-load-bearing structures: Timed collapses and dismantling methods that limit vibration and debris.
• Concrete breaking with low-noise methods: Use of silent demolition tools and anti-vibration techniques for targeted removal.
• Methods and equipment

• Equipment: Quiet-cutting systems, hydraulic shears, silent-mounted implements, electric or low-noise hydraulic breakers, and vibration-damping attachments.
• Techniques: Telemetered control, phased demolition sequences, and precision cutting to avoid overbreak and unintended loading.
• Safety and QA: Real-time monitoring of noise, vibration, and dust; comprehensive RAMS and post-demolition inspections.

Health, safety, and environment

• Permitting and compliance: Coordination with local authorities, noise ordinances, and environmental controls.
• Noise and vibration management: Temporary sound barriers, enclosures, misting for dust, and objective vibration monitoring.
• Safe handling: Lockout/Tagout, PPE, and site-specific RAMS; coordination with occupants for safe evacuation or shelter-in-place if needed.
• Training: Operator certification, toolbox talks, and hazard identifications with ongoing refreshers.

Applications

• Occupied buildings undergoing renovation or redevelopment
• Historic or heritage façades requiring careful deconstruction

1. Consultation and planning: Occupancy schedules, noise limits, and interface with adjacent structures.
2. Permits and coordination: Noise impact assessments, permits, and utility coordination.
3. Silent demolition operations: Phased removal sequences with continuous monitoring of noise and vibration.
4. Cleanup and handover: Debris containment, surface protection, and documentation.
