MEP Code Compliance Across Every Applicable Code Simultaneously
Helonic is an AI construction drawing analysis platform for MEP Engineers doing Code Compliance.
Mechanical, electrical, plumbing, and fire protection each have their own code thickets. Helonic walks all of them.
What is code compliance for mep engineers?
Code compliance for MEP engineers is the simultaneous check of IMC, IPC, NEC, NFPA, ASHRAE, and local utility requirements against the drawings. A single rooftop air handler can implicate IMC ventilation requirements, ASHRAE 62.1 outdoor air calculations, ASHRAE 90.1 efficiency requirements, NEC working clearances for the disconnect, IFC clearance requirements, and local utility standards. Helonic checks every applicable code against the actual drawings.
Why does MEP code compliance take so much review time?
MEP code compliance takes so much review time because it is thousands of small dimensional checks rather than a few big design decisions. The pre-permit review fails because the volume of small checks exceeds what manual review can cover consistently. Helonic runs the volume so the engineer can focus on the design decisions.
How does Helonic help mep engineers with code compliance?
IMC, IPC, NEC, NFPA, ASHRAE, IFC all checked in parallel against the drawings.
Parallel multi-code checking
IMC, IPC, NEC, NFPA, ASHRAE, IFC all checked in parallel against the drawings.
Adopted-edition awareness
Each code rule runs against the edition adopted by the project's AHJ - including any jurisdictional amendments.
Implementation-level checks
Beyond code summary verification - every dimensioned requirement (clearance, slope, spacing, capacity) checked sheet by sheet.
Energy code support
ASHRAE 90.1 prescriptive checks against equipment efficiency, envelope, lighting power density, and controls.
What issues does Helonic catch in code compliance for mep engineers?
Helonic flags these code compliance issues when mep engineers review a set:
Restroom exhaust fan capacity 50 cfm but IMC Table 403.3.1 requires 75 cfm for the occupant load
Sprinkler protection at obstruction within 4'-0" of head violates NFPA 13 8.6.5.1.1
Panel P-1 feeder breaker sized 200A but downstream load calculates 230A - NEC 230.42
Smoke detector spacing 35'-0" in office area violates NFPA 72 17.7.3.2 max 30'-0" for non-smooth ceilings
Roof-mounted equipment lighting power density exceeds ASHRAE 90.1 9.4.1 allowance for the building type
Plumbing vent through roof at less than 12" above roof per IPC 904.1 - minimum height not met
Which Helonic features matter for code compliance?
Helonic includes IMC ventilation and exhaust rate checks when mep engineers run this workflow.
IMC ventilation and exhaust rate checks
IPC fixture count and pipe sizing checks
NEC clearance, panel schedule, and feeder size checks
NFPA 13 sprinkler coverage and obstruction checks
NFPA 72 fire alarm device spacing checks
ASHRAE 90.1 prescriptive energy code checks
How do MEP engineers check code compliance?

What do practitioners say about code compliance for mep engineers?
“MEP engineers we interviewed described code compliance review as 'death by a thousand cuts.' Each individual check is trivial; the volume across an 80-sheet MEP set is what overwhelms manual review.”
Interviews with practicing MEP engineers including PEs across mechanical, electrical, plumbing, and fire protection.
What do mep engineers ask about code compliance?
What about local utility requirements?
Helonic supports custom rule packs for local utility, water authority, and gas utility requirements.
Does it check ASHRAE 90.1 performance-path compliance?
Helonic checks prescriptive items visible on drawings. Performance-path compliance still requires energy modeling, but Helonic can audit the modeling inputs.
Can it handle NEC over multiple editions?
Helonic supports NEC 2017, 2020, and 2023.

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.
