MEP Shop Drawing Review Calibrated to Each Discipline
Helonic is an AI construction drawing analysis platform for MEP Engineers doing Shop Drawing Review.
Submittals from MEP subs arrive every week. Helonic reviews each at the depth the contract requires.
What is shop drawing review for mep engineers?
Shop drawing review for MEP engineers is the comparison of equipment submittals, coordination drawings, and fabrication shop drawings against the contract documents before fabrication. Mechanical equipment submittals carry hundreds of pages; electrical gear submittals carry detailed manufacturing drawings; plumbing fixture submittals carry product cuts plus installation details. Helonic was built to review each submittal type against the contract documents at the depth the design engineer would do under ideal conditions.
How does Helonic help mep engineers with shop drawing review?
Every submitted product checked against the schedule and specification for compliance.
Equipment selection verification
Every submitted product checked against the schedule and specification for compliance.
Performance specification compliance
Submittal performance data checked against specified performance (cfm, btuh, kW, GPM, etc.).
Coordination submittal review
Coordination drawings submitted by subs checked against the latest design drawings.
Substitution request handling
Manufacturer substitution requests handled with basis-of-design comparison and acceptance criteria.
Why does MEP submittal review get compromised?
MEP submittal review gets compromised because contract deadlines force surface-level review of packages that need a full spec comparison. The pressure to return submittals fast - contractually within 14 days - pushes engineers to surface-level review. Helonic does the comprehensive comparison in the background so the engineer's review time is focused on judgment calls.
How do MEP engineers review shop drawings?
Helonic indexes the submittal in the project context.
Upload submittal alongside contract documents
Helonic indexes the submittal in the project context.
Run automated verification
Performance specs, equipment selections, coordination - all checked.
Review deviations
Findings ranked by severity; engineer focuses time on judgment items.
Stamp and return
Draft comments generated; engineer edits, stamps, and returns to GC.
What issues does Helonic catch in shop drawing review for mep engineers?
Helonic flags these shop drawing review issues when mep engineers review a set:
AHU-1 submittal shows cooling capacity 280 MBH but specification requires 300 MBH
Electrical switchgear submittal shows fault current rating 65 kAIC but feeder design assumes 100 kAIC
Plumbing fixture submittal lists low-flow lavatory at 1.5 gpm but spec requires 1.0 gpm max for LEED
Fire sprinkler shop drawings show 130 head spacing for light hazard at 12'-0" but supply analysis based on 12'-6"
Substitution request for VAV box manufacturer not approved equal in spec
Coordination drawing shows ductwork at elevation conflicting with structural beam at grid B-4
Which Helonic features matter for shop drawing review?
Helonic includes Mechanical equipment selection verification when mep engineers run this workflow.
Mechanical equipment selection verification

Substitution request basis-of-design comparison
What do practitioners say about shop drawing review for mep engineers?
“MEP engineers told us submittal review is where they cut corners under deadline, and where they most regretted cutting corners when problems surfaced later. They wanted help with the mechanical comparison so they could focus on the judgment.”

What do mep engineers ask about shop drawing review?
Does it handle multi-document submittals?
Helonic indexes the full submittal package (cover, equipment cuts, coordination drawings, certifications) and reviews each component.
Can it generate the review stamp?
Helonic generates the comments; the engineer applies the stamp. Stamp language matches firm conventions.
What about as-built coordination drawings?
Helonic reviews as-builts submitted at closeout at the same review depth, with focus on documenting actual installed conditions vs. design intent.
