GC-Side Shop Drawing Review Before the Design Team Sees It
Don't waste design-team turnaround time on submittals that obviously don't comply. Filter them first.
GC shop drawing review is a filter, not a substitute for design-team review. The design team has limited turnaround time for submittal review (typically 14 days). When the GC sends submittals that obviously don't comply with the contract documents, that turnaround time gets used returning the submittal for resubmittal. Better: filter at GC-side first, return for resubmittal before the design team sees it.
How Helonic helps
Pre-design-team filtering
Submittals with obvious non-compliance returned to subs for correction before consuming design-team review time.
Schedule protection
Avoid the 14-day resubmittal cycles that compound across multiple submittals.
Sub-trade accountability
Document submittal quality issues to improve sub-trade submittal discipline over time.
Design-team relationship
Don't burn design-team goodwill with low-quality submittals.
Why GC pre-filtering submittals matters
The GCs we work with describe a recurring pattern: a submittal goes to the design team, comes back marked 'Revise and Resubmit,' and the schedule absorbs another 14 days. If the same issue had been caught at GC-side review before submission, the resubmittal cycle would have been a day instead of a month. Helonic enables systematic GC-side filtering.
GC submittal pre-filter
Upload submittal received from sub
Helonic indexes the submittal against contract documents.
Run automated compliance check
Material, dimensional, specification compliance all checked.
Return to sub if non-compliant
Send back with auto-generated comments before consuming design-team review time.
Forward to design team if clean
Submittals reaching design team are pre-filtered for obvious compliance.
Example issues Helonic catches
Real-world issues detected by AI analysis, specific to general contractors running shop drawing review:
Steel fabrication shop drawing shows beam B-12 length 35'-2" but contract drawing shows 35'-6"
Plumbing fixture submittal shows model with 1.5 gpm flow but spec requires 1.0 gpm max for LEED compliance
Light fixture submittal shows L-3 type but spec basis-of-design is L-3a with different photometry
AHU submittal shows cooling capacity 280 MBH but spec requires 300 MBH
Door hardware submittal substitution request for cylinder type not approved equal in spec
Casework submittal P-Lam color doesn't match the finish board approved at FRC
Key features for this workflow
Submittal-to-contract-document comparison
Material specification compliance verification
Dimensional verification against drawings
Substitution request identification and flagging
Submittal completeness audit

What construction professionals told us
“The general contractors we interviewed all described the same realization about submittal review: filtering at GC-side saved more schedule than any other single coordination practice. They wanted automated filtering that didn't depend on senior GC engineers having time to do it manually.”

FAQs
Does this replace design-team review?
No - final review still rests with the design team. GC-side review filters obvious issues so design-team time goes to design judgment.
What if the design team wants to see all submittals?
Some design teams require all submittals to come through them. GC-side review still adds value by helping the design team triage efficiently.
Can subs use this themselves before submitting?
Yes - some GCs encourage subs to run Helonic on their own submittals before delivery to reduce return-and-resubmit cycles.
