Civil Code Compliance Across Site, Stormwater, and Accessibility
Helonic is an AI construction drawing analysis platform for Civil Engineers doing Code Compliance.
Civil work touches more code overlays than design-side disciplines. Helonic walks every one.
What is code compliance for civil engineers?
Code compliance for civil engineers is the site check Helonic runs on accessible routes, fire access, stormwater, and utility separations before the civil set is submitted. ADA for accessibility, IBC and IFC for fire access, local stormwater ordinances, utility-specific codes (water, sewer, gas), wetlands and floodplain regulations, and jurisdictional development standards. Helonic supports the full set against the drawings.
Why is civil code compliance so broad?
Civil code compliance is broad because one site plan has to satisfy ADA, fire access, stormwater, utility codes, wetlands, and local development standards together. The codes themselves are straightforward; the burden is verifying that every applicable code is satisfied on every relevant drawing across the entire site. Helonic handles the volume so the engineer can focus on interpretation.
How does Helonic help civil engineers with code compliance?
Helonic checks accessible routes, parking aisles, and curb ramps against the slope and landing dimensions those rules require.
ADA site accessibility compliance
Helonic checks accessible routes, parking aisles, and curb ramps against the slope and landing dimensions those rules require.
IFC fire access compliance
Fire-lane width, distance to the fire department connection, and turnarounds are checked against the fire code appendix and the local fire department standard.
Stormwater ordinance compliance
Volume, water-quality, and peak-rate numbers on the stormwater plan are checked against the ordinance and the drainage area on the drawings.
Utility code compliance
Water-main separation, sewer slope, and service clearances are checked against the utility standards named for the project.
What issues does Helonic catch in code compliance for civil engineers?
Helonic flags these code compliance issues when civil engineers review a set:
Accessible curb ramp at parking aisle: slope 1:11 computed from spot elevations - exceeds 1:12 per ADA 406.1
Fire department access road exceeds 150' from FDC with no turnaround - IFC Appendix D requires turnaround beyond 150'
Stormwater volume detained 0.42 ac-ft but local ordinance requires 0.52 ac-ft for the impervious area
Sanitary sewer slope at station 2+30 calculated 0.20% - local code requires 0.40% min for 8" PVC
Gas main depth at station 1+45 shows 24" cover but gas utility code requires 30" min in driving lanes
Wetland buffer at proposed parking expansion 12'-0" - local wetland ordinance requires 25'-0" min
Which Helonic features matter for code compliance?
Helonic includes ADA site accessibility check when civil engineers run this workflow.
ADA site accessibility check
IFC fire access road and turnaround verification
Local stormwater ordinance compliance

Local development standard compliance
How do civil engineers run a code compliance check?
Helonic loads the overlays that apply to the site: accessible-route rules, fire-access dimensions, the local stormwater ordinance, and the utility separation standards.
Identify applicable regulatory overlays
Helonic loads the overlays that apply to the site: accessible-route rules, fire-access dimensions, the local stormwater ordinance, and the utility separation standards.
Upload civil drawings
Grading, utility, paving, and erosion-control sheets are read as one civil set.
Run multi-overlay compliance
Curb-ramp slope, fire-lane length, stormwater volume, and pipe separation are checked together against those overlays.
Resolve and document
The engineer corrects the misses and keeps the sheet, the measurement, and the rule that failed.
What do practitioners say about code compliance for civil engineers?
“Civil engineers told us the hard part was breadth. One site has to satisfy a lot of overlays at once, and a person cannot hold every one of them on every sheet.”

What do civil engineers ask about code compliance?
Can it handle multiple jurisdictions on one project?
Helonic handles multiple jurisdictions on one project, applying the appropriate rule set per location (e.g., site work in one city, utility extension in another).
What about specific local development codes?
Helonic supports custom rule packs for jurisdiction-specific development standards. Upload the standard once; future projects in the same jurisdiction use it automatically.
Does it check NPDES requirements?
Helonic checks NPDES and CGP requirements against the SWMP and erosion control drawings.
