Power Plant Demolition

Onyx Engineering provides end-to-end demolition services for industrial plants and processing campuses. Our approach emphasizes safety, regulatory compliance, minimal disruption to operations, and responsible waste management. From selective decommissioning and line clearance to full plant teardown, we tailor solutions to complex equipment, hazardous materials, and environmental controls.

why choose Onyx engineering

• Structured planning and sequencing: Detailed scoping, load-path analysis, and phased demolition to minimize downtime.
• Safety and compliance: ISO 45001:2018 and ISO 9001:2015, with RAMS, permits-to-work, and on-site supervision.
• Industrial-grade capability: Heavy process equipment, piping networks, multi-story facilities, and intricate utilities.
• Salvage and recycling: Opportunities to recover usable components and materials, reducing waste and cost.
• Environmental stewardship: Dust/noise control, containment of hazardous substances, and responsible decommissioning.

Demolition capabilities

• Process equipment removal: Reactors, boilers, distillation columns, heat exchangers, skids, and ancillary equipment.
• Plant and line clearance: Decommissioning production lines, cellular layouts, mezzanines, and ancillary structures.
• Mechanical and electrical decommissioning: Safe isolation and removal of piping, conduits, MCC rooms, and control systems.
• Structural and shell demolition: Interior stripping, envelope work, and load-path aware demolition.
• Hazardous materials handling: Containment and compliant removal of asbestos, lead-based paints, solvents, and other regulated substances when present.

Methods and equipment

• Equipment: Heavy demolition gear, remote-operated cutters, hydraulic shears, grinders, robotic systems, and cranes with specialized attachments.
• Techniques: Controlled sequencing, load-path management, selective dismantling, dust/mist suppression, and cross-system disconnections.
• Safety and QA: Site-specific RAMS, lift plans, lockout/tagout, QA/QC checks, air monitoring, and post-demolition validation.

Health, safety, and environment

• Permitting and compliance: Permits-to-work, utility disconnections, environmental controls, waste handling plans, and regulatory reporting.
• Dust, noise, and vibration control: Enclosures, misting systems, acoustic barriers, and vibration monitoring.
• Safe handling: PPE programs, confined-space considerations, respiratory protection, and emergency response planning.
• Training: Operator qualifications, toolbox talks, hazard identifications, and ongoing competency programs.

Applications

• Greenfield to brownfield transitions: Complete demolition or phased decommissioning to enable redevelopment.
• Equipment retrofits and upgrades: Clearing obsolete lines and machinery for new installations.
• Facility closures and site remediation: Demolition as part of site repurposing or remediation projects.
• Heritage and sensitive facilities.
