Engineering Services
Field-verified electrical data becomes a documented model, defensible calculations, and clear actions for owners and qualified workers.
Electrical safety study
Arc Flash Studies
We verify site data, build the electrical system model in SKM Power*Tools, evaluate the hazards, and turn the results into a usable safety package.
See why, when, and what you receive →Typical study package
- Short-circuit, equipment-duty, coordination, and incident-energy analysis
- Updated one-line diagram and documented system model
- Complete engineering report with prioritized recommendations
- Equipment-specific arc flash and shock hazard labels
Our field service standard
Prepared to respond when site conditions change.
Rapid triage, clear communication, and disciplined mobilization are built into every field engagement. For urgent site needs, we align safety, access, evidence, tools, and escalation before the crew arrives.
