MEP QA/QC That Reconciles Every Schedule, Every Time
MEP sets carry the most schedules of any discipline. Helonic reconciles them all.
MEP drawing sets contain more schedules than any other discipline - equipment schedules, fixture schedules, panel schedules, fire alarm device schedules, plumbing schedules. Each schedule needs to reconcile with the drawings, the spec, the load calculations, and adjacent schedules. Helonic performs comprehensive MEP QA/QC by treating the schedule reconciliation as a graph problem and surfacing every inconsistency.
How Helonic helps
Comprehensive schedule reconciliation
Every schedule cross-checked against the drawings and adjacent schedules.
Equipment-to-circuit traceability
Every mechanical equipment item traced to its electrical circuit and panel schedule entry.
Fixture-to-vent traceability
Every plumbing fixture traced to its vent and waste stack.
Device-to-zone traceability
Every fire alarm device traced to its zone and circuit.
MEP schedule density
An MEP set can have 15+ distinct schedules across mechanical, electrical, plumbing, and fire protection. Each schedule has hundreds of entries. The volume of cross-references is enormous, and human reviewers consistently underdeliver thorough reconciliation. Helonic does it at machine speed.

Example issues Helonic catches
Real-world issues detected by AI analysis, specific to mep engineers running qa/qc:
Mechanical equipment schedule lists VAV-12 but no VAV-12 shown on plans
Panel P-2 schedule shows circuit 14 feeding AHU-2 but AHU-2 disconnect schedule shows circuit 16
Plumbing fixture P-12 (lavatory) shown on plan but no entry in fixture schedule
Fire alarm device F-203 (smoke detector) shown on plan but missing from device schedule
Equipment ERV-1 in schedule but no electrical disconnect in panel schedule for it
AHU-3 condensate drain shown on mechanical at 3/4" but plumbing fixture schedule shows 1"
Key features for this workflow
Mechanical equipment schedule reconciliation
Electrical panel schedule reconciliation
Plumbing fixture and waste/vent schedule reconciliation
Fire alarm device schedule reconciliation
Equipment-to-circuit-to-panel traceability
Schedule-to-spec coverage audit
What construction professionals told us
“MEP engineers we talked with said schedule reconciliation was the QA task they most wanted automated. The volume was the issue - not the difficulty of any individual check, but the sheer number of cross-references.”

FAQs
Can it handle our schedule formats?
Yes - Helonic adapts to firm-specific schedule formats and column layouts.
What about schedules that span multiple sheets?
Helonic indexes multi-sheet schedules as single logical schedules and reconciles across the full schedule.
Does it work for design-build MEP submittals?
Yes - particularly useful for design-build because schedules evolve faster and manual reconciliation falls further behind.

He works directly with structural, MEP, civil, and fire protection engineers to translate the way they review drawings into AI systems that flag the issues that actually matter in the field. Before Helonic, he built machine learning pipelines for technical document understanding and has spent the last several years interviewing licensed design engineers and discipline leads to ground product decisions in real practice rather than industry assumptions.
