GC Coordination Review for the Issues Design Teams Missed
GCs catch coordination issues in the field. With Helonic, you catch them at the documents.
General contractors are the ones who eat the cost when coordination issues surface in the field. A ductwork-vs-beam conflict that the design team missed becomes a change order, a delay, and erosion of trade relationships. GCs running their own coordination review catch the issues at the document stage - when they're still cheap to fix.
Why GCs run coordination review the design team should have done
The GCs we work with consistently describe the same experience: they discover coordination issues in the field that the design team's review didn't catch. The reason isn't design-team incompetence - it's that design teams don't get to walk the building during installation. GCs do, and they know exactly which patterns recur. Helonic encodes those patterns and lets GCs run pre-construction coordination review.
GC coordination workflow
Upload all discipline drawings
Architectural, structural, MEP, FP, civil - all indexed together.
Run GC-perspective coordination
Cross-discipline conflicts surfaced with field-installation lens.
Pre-construction coordination meetings
Use findings as agenda for sub-trade coordination meetings before mobilization.
Track resolution through construction
Each finding resolved either through design revision or pre-installed coordination decision.
How Helonic helps
GC-perspective coordination logic
Coordination logic built around field-installation patterns, not just drawing-review patterns.
Above-ceiling clarity before installation
Plenum congestion identified before the field discovers it.
Sub-trade pre-construction coordination
Use Helonic findings to inform pre-construction coordination meetings with sub-trades.
Owner relationship protection
Catching coordination issues at document review prevents the disruption that erodes owner trust.
Key features for this workflow
Cross-discipline conflict detection on 2D drawings
Above-ceiling plenum analysis
Field-installation pattern recognition
Sub-trade boundary clarification
Pre-installation coordination prep
Coordination meeting agenda generation
Example issues Helonic catches
Real-world issues detected by AI analysis, specific to general contractors running coordination review:
Corridor plenum at grid B-2: 24" supply duct + 8" sprinkler main + 4" conduit rack require 36" total; available plenum 24"
Mechanical room equipment access blocked by structural beam at grid C - equipment cannot be installed without disassembly
Sprinkler head at light fixture obstruction within 4'-0" - NFPA 13 violation requires relocation in field
Fire damper required at 2-hour wall penetration not shown on either mechanical or fire protection drawings
Cable tray at 9'-6" AFF conflicts with conduit rack at 9'-4" AFF - physical conflict above corridor
Plumbing waste line slope from grid A to riser conflicts with structural beam below - invert too high
What construction professionals told us
“The general contractors we talked with all described the same realization: by the time their superintendent discovered a coordination conflict in the field, the cost to resolve was 10–20× what it would have been at design. They wanted that resolution to happen at design, with their team driving the process.”

FAQs
Should we share findings with the design team?
Yes - most GCs share findings collaboratively and the design team welcomes the extra coordination layer. Some GCs use findings as private bid-stage risk assessment instead.
What about BIM coordination?
If the project has a current federated BIM model, BIM coordination is the primary tool. Helonic complements BIM by catching items in disciplines that aren't fully modeled.
Can it work on issued-for-construction documents?
Yes - running on IFC docs surfaces the items the design team's coordination didn't catch, which is when GC-side coordination becomes most valuable.
