Code Compliance Verification at the Sub-Trade Scope Level
Helonic is an AI construction drawing analysis platform for Subcontractors doing Code Compliance.
Inspector flags fall on sub-trade installations. Verify your scope is compliant before installation.
What is code compliance for subcontractors?
Code compliance for subcontractors is a pre-install check for the trade-scope violations inspectors usually find, including panel clearances, sprinkler spacing, and plumbing slopes. Sub-trades who run their own compliance check catch these items before installation, when they cost minutes to fix instead of hours of rework.
Where do sub-trade compliance failures actually happen?
Sub-trade compliance failures we've reviewed across projects cluster around dimensional items that surface only when installed: panel clearances, sprinkler obstructions, fire damper installations, plumbing slopes. Helonic checks these dimensional items in the documents before installation.
How does Helonic help subcontractors with code compliance?
Checks scoped to codes affecting your trade scope.
Trade-specific compliance focus
Checks scoped to codes affecting your trade scope.
Pre-installation verification
Compliance items resolved before installation.
Inspector-readiness
Documentation supports clean inspections.
Rework cost avoidance
Pre-installation fixes are 10× cheaper than post-installation rework.
What issues does Helonic catch in code compliance for subcontractors?
Helonic flags these code compliance issues when subcontractors review a set:
Electrical panel clearance 32" - NEC 110.26 requires 36" - installation violation
Sprinkler at 4'-0" of light fixture - NFPA 13 obstruction
Plumbing waste slope 1/8"/ft for 4" pipe - IPC 704.1 verification
Mechanical disconnect not within sight of equipment - NEC 422 violation
Smoke detector at 35'-0" spacing - NFPA 72 30'-0" max
Fire damper installation at penetration without sleeve - UL listing violation

What do practitioners say about code compliance for subcontractors?
“Sub-trade project managers we talked with said failed inspections were their largest single source of unbilled overtime - rework had to be done fast to recover schedule. They wanted automated compliance checks pre-installation.”

What do subcontractors ask about code compliance?
Doesn't the design team verify this?
Helonic's sub-trade check verifies installation after the design team verifies documents. Both layers add value.
What about field-tolerance items?
Helonic flags items at field-tolerance boundaries so installation care is documented.
Can sub-trades push back on design issues?
Helonic flags document compliance items that would cause installation failure so sub-trades can push back via RFI to the design team.
