Foundation plan review
Helonic is an AI construction drawing analysis platform for preconstruction teams using Helonic for foundation review.
Analyze foundation plans for coordination issues with underground utilities and structural elements. Helonic cross-references geotechnical recommendations, civil utility plans, and structural foundation drawings to catch conflicts before excavation begins.
Why does foundation review matter?
Foundation work is the first trade on site and the least forgiving, because a misplaced footing or sleeve is demolished concrete.
| Figure | What it measures |
|---|---|
| 5x | More expensive to fix foundation errors after pour |
| 20% | Foundations that have utility conflicts at construction |
| 100% | Footings checked against underground systems |
| Geo | Cross-reference of geo report bearing and depth |
How does Helonic go from foundation plans to a conflict report?
Helonic checks structural, civil, plumbing, and geotechnical against each other.
- Read foundation plans. The AI extracts every footing, grade beam, pile cap, slab edge, and depression from the structural foundation plan, including sizes, elevations, and reinforcement callouts.
- Overlay utilities. Underground plumbing, storm drains, site electrical, gas lines, and civil utility routing are mapped from their respective drawings and overlaid on the foundation layout.
- Check clearances. Every intersection of a utility with a structural element is checked for adequate clearance, proper sleeving, and whether the utility routing conflicts with reinforcement zones.
- Report conflicts. Conflicts are reported with exact locations, affected elements, and recommended coordination actions, such as re-routing a sewer line or adding a structural sleeve.
What foundation conflicts does Helonic check?
Helonic checks footing locations versus underground utilities, hold-down layouts versus architectural walls, and slab depressions versus structure.
- Footing vs utility conflicts. Identifies where underground plumbing, storm, or electrical lines pass through or under spread footings, continuous footings, or pile caps where excavation would undermine bearing capacity.
- Grade beam coordination. Checks that grade beams do not conflict with underslab plumbing routing, particularly at bathroom and kitchen core locations where dense plumbing runs converge.
- Pile cap layout verification. Verifies that pile cap locations and sizes match the structural column grid and that pile spacing does not conflict with deep utility trenches or adjacent footings.
- Foundation drain routing. Traces foundation perimeter drain routing to verify proper slope, outlet connections, and that drain lines do not conflict with footing steps or utility penetrations.
- Slab depression coordination. Maps all slab depressions (for tile, showers, ramps, equipment pads) and verifies they do not conflict with post-tension cables, underslab ductwork, or reinforcement schedules.
- Elevation consistency. Cross-references foundation top-of-concrete elevations across structural plans, architectural sections, and civil grading plans to catch inconsistencies that cause fit-up problems.
Why are foundation conflicts so expensive to fix?
Foundation work is the first major trade activity on site, and it is the least forgiving of errors. Once concrete is poured, correcting a misplaced footing or a utility conflict means expensive demolition, re-engineering, and schedule delays that cascade through every subsequent phase.
The challenge is that foundation coordination requires cross-referencing multiple disciplines (structural, civil, plumbing, and geotechnical) that are often designed by different firms on different timelines. Helonic automates this multi-discipline cross-check, catching the conflicts that fall between the gaps of individual design reviews.
