MEP QA/QC That Reconciles Every Schedule, Every Time
Helonic is an AI construction drawing analysis platform for MEP Engineers doing QA/QC.
MEP sets carry the most schedules of any discipline. Helonic reconciles them all.
What is qa/qc for mep engineers?
QA/QC for MEP engineers is the schedule check Helonic runs across equipment, panel, and fixture lists before the MEP set is issued. Each schedule needs to reconcile with the drawings, the spec, the load calculations, and adjacent schedules. Helonic reconciles every schedule against the rest of the set and lists every mismatch.
How does Helonic help mep engineers with qa/qc?
Helonic matches every MEP schedule line to the plans and to the adjacent schedule, including a VAV listed in the schedule and missing on the plan.
Schedules matched to the plans

Equipment-to-circuit traceability
Each piece of mechanical equipment is traced to the circuit and panel schedule entry that is supposed to feed it.
Fixture-to-vent traceability
Each plumbing fixture is traced to a vent and a waste connection on the riser or the plan.
Device-to-zone traceability
Each fire-alarm device is traced to the zone and circuit shown on the fire-alarm drawings.
Why is thorough MEP QA hard to do by hand?
Thorough MEP QA is hard to do by hand because an MEP set can have 15 or more 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.
How do MEP engineers run set QA/QC?
Helonic indexes the mechanical, electrical, plumbing, and fire-alarm drawings with their schedules and specifications as one set.
Upload complete MEP set
Helonic indexes the mechanical, electrical, plumbing, and fire-alarm drawings with their schedules and specifications as one set.
Run schedule reconciliation
Equipment tags, circuits, fixtures, and devices are matched from each schedule back to the plans and to the neighboring schedule.
Review findings by severity
A missing VAV, a circuit that disagrees between the panel and the disconnect, or a fixture with no vent is cleared before the quieter mismatches.
Generate QA report
Helonic writes a QA record that names the schedule line and the plan sheet that disagree.
What issues does Helonic catch in qa/qc for mep engineers?
Helonic flags these qa/qc issues when mep engineers review a set:
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"

What do practitioners say about qa/qc for mep engineers?
“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.”

What do mep engineers ask about qa/qc?
Can it handle our schedule formats?
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?
Helonic works for design-build MEP submittals because schedules evolve faster and manual reconciliation falls further behind.
