AI drawing review for electrical contractors
Verify panel schedules, coordinate conduit routing, and catch load calculation errors before installation begins.
What slows down electrical contractors
The recurring drawing problems behind most electrical field changes and RFIs.
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 Helonic helps
From panel schedules to emergency power, Helonic reads every electrical sheet in your set.
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.
Common issues we catch
The electrical conflicts and code gaps Helonic surfaces on every drawing set.
Panels & Circuits

- 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

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.
