Independent Electrical Engineering

Power system studies, built for the decisions that cannot wait.

HeirArc delivers PE-stamped arc flash, selective coordination, and short circuit studies for industrial, commercial, and mission-critical facilities. Scope is clear, fees are fixed, and the work moves online.

The right study starts with the question

Safety. Uptime. Equipment ratings. Or all three together.

Start with the outcome your facility needs. We will help identify the study, confirm the available data, and provide a fixed-fee scope before engineering work begins.

What do you need to know?

Three clear paths, with the short circuit model included wherever it supports the answer.

Personnel safety

Arc Flash

Know the incident energy at each location and put usable information on every panel.

Arc flash study
Uptime & selectivity

Coordination

Set devices so the closest protection clears a fault and the rest of the plant keeps running.

Coordination study
Design & equipment ratings

Short Circuit

Confirm available fault current and whether installed gear is rated to handle it.

Short circuit study
One model, complete answer

Need safety and uptime together?

The Complete Power System Study brings arc flash, selective coordination, and short circuit together—so the label on the door matches the settings sheet inside the gear.

A straightforward online workflow with practical information at every stage.

01 — Data

Share what you have

One-lines, nameplates, and existing device settings establish the scope. We tell you what is missing.

02 — Fee

Approve a fixed scope

The fee and deliverables are confirmed in writing before work starts. No hourly uncertainty.

03 — Delivery

Receive a sealed study

Follow progress by project ID, then receive a PE-stamped deliverable ready for its intended use.
