Sub-Trade Coordination Review That Prevents Back-Charges
Helonic is an AI construction drawing analysis platform for Subcontractors doing Coordination Review.
Conflicts between trades surface as back-charges. Catch them at documents.
What is coordination review for subcontractors?
Coordination review for subcontractors is a pre-install check for conflicts between their scope and adjacent trades. A ductwork-vs-conduit conflict in the corridor becomes a question of which trade reroutes - and which trade absorbs the cost. Helonic helps sub-trades identify cross-trade coordination items at the document stage, when they're easier to resolve through coordination meetings than back-charges.
How does Helonic help subcontractors with coordination review?
Cross-trade conflicts affecting your scope surfaced.
Trade-vs-trade conflict detection
Cross-trade conflicts affecting your scope surfaced.
Pre-installation resolution
Conflicts resolved through coordination meetings, not back-charges.
Back-charge prevention
Conflicts caught pre-installation rarely become back-charge disputes.
Trade relationship protection
Pre-installation coordination preserves working relationships.
Why do coordination conflicts cost subcontractors so much?
Coordination conflicts cost subcontractors because they often become back-charges, and the trade that installed the conflicting work absorbs the cost. The trade with the conflict in their scope absorbs cost; the trade with the conflict 'in someone else's scope' avoids it. Pre-installation coordination reverses the dynamic - both trades share visibility into conflicts before installation starts.
How do subcontractors catch trade-to-trade conflicts before install?
Helonic identifies trade-vs-trade conflicts.

What issues does Helonic catch in coordination review for subcontractors?
Helonic flags these coordination review issues when subcontractors review a set:
Your ductwork at 9'-6" AFF in corridor conflicts with sprinkler main at 9'-4" AFF
Your conduit routing conflicts with plumbing waste line at corridor C-3
Your mechanical equipment access blocked by structural beam at grid B-4
Your fire sprinkler obstructed by 24" duct within 4'-0"
Your cable tray conflicts with conduit rack from another sub at elevation 9'-4"
Your plumbing vent through roof conflicts with HVAC unit clearance

What do practitioners say about coordination review for subcontractors?
“Sub-trade project managers we talked with said back-charges were the most damaging form of project conflict - they damaged trade relationships and consumed PM time. They wanted automated detection of conflicts pre-installation.”

What do subcontractors ask about coordination review?
Should the GC or sub run coordination?
Helonic supports coordination at both levels: GC cross-discipline and sub-trade-specific. GCs run cross-discipline coordination; sub-trades run trade-specific coordination on their work.
What if BIM coordination already happened?
Helonic complements BIM by catching items missed in modeling or affecting trades not in the model.
How early should we run this?
Helonic is typically run by sub-trades 2-4 weeks before mobilization to allow time for coordination resolution.
