AI drawing review for electrical contractors

Helonic is an AI construction drawing analysis platform for electrical contractors who review 2D PDF drawing sets.

Verify panel schedules, coordinate conduit routing, and catch load calculation errors before installation begins.

What slows down electrical contractors?

Electrical contractors lose margin when panel schedules, feeder sizes, and emergency-power sheets disagree before rough-in.

Panel Schedule Mismatches

Panel schedules frequently disagree with one-line diagrams and equipment power requirements, creating costly field changes.

Conduit Routing Conflicts

Conduit runs clash with ductwork, piping, and structural elements in crowded ceiling spaces and vertical chases.

Load Calculation Errors

Circuit loading exceeds panel capacity or wire sizing is insufficient for the connected loads shown on equipment schedules.

How does Helonic help?

Helonic reads panel schedules, one-lines, and floor plans together and flags load, routing, and emergency-power conflicts before install.

Panel Schedule vs One-Line Verification

Cross-reference panel schedules against one-line diagrams and riser diagrams to flag mismatched breaker sizes, missing circuits, and inconsistent load designations.

Conduit Pathway Coordination

Detect where conduit runs conflict with ductwork, piping mains, and structural elements. Identify congested pathways that will create installation problems.

Lighting Layout vs Ceiling Coordination

Verify that light fixture locations align with the reflected ceiling plan and do not conflict with diffusers, sprinkler heads, or structural members.

Power to Equipment Matching

Ensure that mechanical equipment schedules, kitchen equipment lists, and other power loads match the circuits and voltage shown on electrical drawings.

Emergency Power System Review

Check that emergency and standby power systems serve all required loads per code, with proper transfer switch sizing and generator capacity.

What issues does Helonic catch?

Helonic flags schedule-to-plan mismatches, conduit clashes, working-clearance misses, and emergency-power gaps before they hit the field.

Panels & Circuits

Circuit overloading beyond panel capacity
Missing homerun designations on floor plans
Breaker sizing mismatches with wire gauge
Incomplete panel schedule load summaries

Coordination & Code

Switch and outlet placement conflicts with furniture layouts
Emergency vs normal power separation violations
Conduit routing through fire-rated assemblies without firestop
Missing GFI protection in required wet locations

What return do electrical contractors see with Helonic?

Electrical teams bid and install with fewer panel and routing surprises because the set is reconciled before material is released.

Frequently Asked Questions

What does Helonic check before electrical rough-in?

It verifies panel locations, conduit routing, and clearance requirements, flagging NEC 110.26 working-space violations, panel conflicts, and conduit clashes with structure or other trades, each with the sheet reference, before rough-in.

Does it check NEC working space and clearances?

Yes. It flags where panel and equipment working clearances do not meet NEC 110.26 and related provisions as drawn.

Can it catch conduit and panel coordination conflicts?

Yes. It flags conduit routing and panel placements that clash with structure, ductwork, or plumbing, the conflicts that drive field rework.

Does it need a 3D model?

No. It works on the 2D electrical and coordinated PDFs you already have.

Code compliance automation (IBC, NEC, NFPA, IPC, IMC, ASCE)
Structural and MEP drawing review systems

How this page was researched: Coordination checks reference NEC (NFPA 70) clearance and working-space requirements, panel and conduit routing, and the electrical-structural interfaces verified before rough-in. Examples are drawn from Helonic's review of electrical sets against the base building set.
