Civil Coordination Across Site, Building, and Utilities
Civil coordination spans the property line. Helonic checks both sides.
Civil coordination is unique because it spans the boundary between site and building. Civil engineers coordinate with architects on grades, with MEP on utility tie-ins, with structural on foundation depths, and with landscape on planting and grading interface. Each interface is a place where coordination can break down. Helonic was built to verify all of them.
The boundary problem in civil coordination
Civil work meets building work at the property line, the building foundation, the utility tie-ins, and the accessible route. Each interface is documented twice - once by civil and once by the building-side discipline. When the documentation doesn't match, the field has to reconcile. Helonic surfaces the reconciliation items at design.

How Helonic helps
Site-to-building grade reconciliation
Civil finish grades cross-checked against architectural finish floor elevations and entry conditions.
Utility tie-in coordination
Civil utility stub-outs cross-checked against building MEP entry locations and sizing.
Accessible route continuity
Accessible route checked from public way through site to building entry - slopes, widths, surfaces all verified end-to-end.
Foundation-utility separation
Underground utilities cross-checked against structural foundation locations for required separations.
Key features for this workflow
Site grade to architectural FFE reconciliation
Utility stub-out vs. building MEP coordination
Accessible route continuity check across site and building
Underground utility vs. foundation separation
Landscape grading vs. civil grading interface
Fire access vs. building footprint coordination
Example issues Helonic catches
Real-world issues detected by AI analysis, specific to civil engineers running coordination review:
Civil finish grade at building entry 100.0' but architectural FFE 100.5' - 6" step at entry not coordinated
Civil 6" water service stub-out at station 1+30 but plumbing site entry shows 4" - sizing mismatch
Accessible route on civil shows 1:18 slope but architectural ramp at building shows 1:12 - total route exceeds 1:12 max for first 50'
Underground electric service on civil routes under footing F-2 - separation per NEC and structural requirements
Landscape grade at planting bed adjacent to building exceeds 8% slope per landscape spec but civil grading shows 5%
Fire access road radius at building turn 28' clear but apparatus requires 30' inside clear per IFC Appendix D
What construction professionals told us
“Civil engineers we talked with said the painful coordination moments were always at boundary conditions - site to building, civil to MEP, civil to landscape. They wanted automated checks that respected the boundaries.”

FAQs
Does this work for greenfield development?
Yes - greenfield benefits substantially because coordination is established at design rather than retrofit to existing.
What about phased site development?
Helonic handles phased work with explicit phase tracking and inter-phase coordination checks.
Can it check landscape coordination?
Yes - landscape drawings can be uploaded alongside civil for grade and planting bed coordination.

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.
