For architects · residential & commercial builders · estimators · plan reviewers
Scan architectural plans into material takeoffs and building code audits in seconds.
Upload your proposed floor, framing, and foundation sheets. AutoPlan.systems runs parallel Jev 1.14.0 bounding-box and state calls to populate a structured building model, calculate itemized material takeoffs by floor and room, and flag IRC/IBC code violations before permit submission.
4 pre-loaded architectural sets + custom plan upload · ~0.2s per 128-question Jev batch · 100% deterministic takeoff arithmetic
Live Pipeline Snapshot · Project RES-2026-OAKWOOD (2-Story Residential + Deck)
From 2D framing & floor plans to itemized costs and IRC code remediation.
Drawn 2x8 #2 SPF @ 16" O.C. spans 15'-6", exceeding the 12'-3" maximum in Table R502.3.1(2). Reasoning Agent Fix: Upsize to 2x12 #2 DF-L (+$335).
Deck joists drawn at 24" O.C. under 5/4 composite decking (16" O.C. max) and Sonotubes drawn at 10"Ø × 30" deep in a 42" frost zone. Fix: 2x10 PT @ 16" O.C. + 16"Ø × 48" piers (+$492).
Sleeping room window sill drawn at 48" AFF with 4.6 sq.ft. opening (Code requires ≤44" sill & ≥5.7 sq.ft. clear). Fix: 36"×60" Casement @ 36" Sill (+$220).
Why Host Code + Jev Beats End-to-End LLMs
Jev perceives and judges in parallel. Deterministic host code does all the math.
Populates a live building model from your floor & framing plans.
Jev bounding-box localization (`GuardedBox`) scans each sheet against our reference library of symbols and assemblies—identifying occupancy (residential vs. commercial), number of floors, total square footage, rooms, walls, fixtures, lumber sizes, O.C. joist spacing, Simpson fasteners, beams, and Sonotube piers.
Instant material takeoff & multi-pivot cost rollups.
Host code—never a generative LLM guessing numbers—cross-references every extracted wall, joist bay, header, and room against our 3-tier pricing catalog. View live totals for the 1st Floor vs. 2nd Floor, Exterior Materials, Bathroom 1 Total, or Kitchen Total (broken down into Cabinets, Countertops, and Fixtures).
Checks every span, footing, door & egress window against code at once.
We serialize the extracted building state and run parallel Jev `Noul` and `Choice` batteries across IRC/IBC span tables, deck joist spacing limits, frost footing depths, Sonotube diameters, 32" door clear widths, and 44" bedroom egress window sill heights in ~200ms.
Code Book Reasoning Agent invoked only when a check fails or flags.
Passing elements settle immediately in Jev with zero LLM cost. Only failed or borderline flags wake the Building Code Reasoning Agent, which consults the IRC/IBC code corpus, confirms the violation, and offers 1-click engineering fixes with exact takeoff cost deltas.
