AI runs at two fixed points
on every project

At intake, StruxBIM™ reads the EOR's design drawings, flags every ambiguity, and drafts RFIs before our team models a single member. Before delivery, it checks every member and connection against AISC 360-22, ASCE 7-22, and IBC before any drawing goes to you.

Before detailing begins

Three AI capabilities run on the EOR's design drawings before our team models a single member. The goal: eliminate every ambiguity before it becomes a revision cycle.

Detailing does not begin until every critical RFI is answered and the extracted data layer is engineer-verified.
01

Design Drawing Extraction

Vision AI + NLP

StruxBIM™ reads the engineer of record's PDF drawings using a dual-engine pipeline — AI vision for raster/scanned PDFs, structured text extraction for vector PDFs — and builds a verified data layer covering every member designation, grid line, connection type, and dimension before detailing starts.

  • Extracts W-sections, HSS, angles, channels, and custom sections from PDF drawings
  • Identifies grid references, dimension strings, and general notes page by page
  • Confidence score per extracted item — low-confidence items flagged for engineer review
  • All extracted data reviewed and verified by an engineer before detailing starts
02

Ambiguity & Issue Detection

Rule Engine + AI

Two detection passes run over the extracted data. A rule engine checks for completeness against AISC 303-22 requirements — missing grids, ambiguous member labels, absent connection details. An AI model then analyzes the full dataset for constructability concerns and fabrication-critical gaps.

  • Flags member designations that don't match AISC naming conventions
  • Detects dimensional conflicts between plan views, elevations, and section cuts
  • Identifies members missing connection type, grid reference, or critical dimension
  • Every finding categorized by severity: Critical, Warning, or Info — with source page reference
03

Automated RFI Drafting

AI-Drafted

When an issue requires clarification from the engineer of record, StruxBIM™ drafts the RFI automatically. Each email is technically precise with full project context and a clearly stated question. Multiple findings are grouped into a single package to minimize EOR interruptions. Detailing does not begin until every critical RFI is answered.

  • Auto-numbered RFIs per project: RFI-001, RFI-002, and so on
  • Multiple findings grouped into one RFI package to reduce EOR interruptions
  • Full lifecycle tracking: Draft → Sent → Answered → Closed
  • RFI answers trigger a version snapshot — complete audit trail for every clarification
Before Delivery

Pre-Delivery
Code Verification

Before any drawing package goes to a client, StruxBIM™ runs our structural model through AISC 360-22, ASCE 7-22, and IBC. Every member is checked — not spot-checked. Every check returns the governing equation and utilization ratio. No drawing leaves without passing this gate.

AISC 360-22 — Member Checks
§E
Flexural and torsional buckling for columns, slender element reductions
§F
Yielding and lateral-torsional buckling for beams
§G
Web shear strength
§H
Combined axial and flexural loading interaction
ASCE 7-22 & IBC — Load & Deflection
ASCE §12.8
Equivalent lateral force seismic checks, storey drift limits
ASCE Ch.27
MWFRS wind pressure for enclosed buildings
IBC T.1604.3
Live load and total load deflection limits
No drawing leaves our desk without passing this gate. That's what first-pass acceptance means.
Standards Coverage

Which codes does

What We're Building Next

StruxBIM™ Roadmap

Honest extensions of what StruxBIM™ already does. We won't build what modelling software already handles well.

Drawing Revision Change Detection

Planned

When the EOR issues a revised drawing set, StruxBIM™ will automatically compare it against the previous extraction — flagging exactly which member designations, dimensions, or connection types changed, and which shop drawings are affected.

  • Side-by-side diff of Rev A vs Rev B at the member level
  • Change impact report: which shop drawings are affected
  • Auto-drafted revision notification to the detailing team

No other detailing service does this today. Be first to know when it ships.

No spam. We'll email you when this is ready for beta.

Pre-Detailing Cost Signal

Planned

Before modeling begins, StruxBIM™ uses the member designations and quantities already extracted at Step 01 to produce a rough cost range — traceable to the source drawing, sheet, and member. Early budget clarity without waiting for the full 3D model.

  • Cost range from Step 01 extracted member data — before modeling starts
  • Every line item traceable to source drawing, sheet, and member designation
  • Integrated with the verified data layer — not a standalone extraction

Model-Derived Quantity Take-off

Planned

Read exported model data (IFC, CIS/2, DSTV, Excel BOM) and automatically extract material weights, bolt counts, weld lengths, and fabrication complexity for an accurate cost estimate — before drawings are issued.

  • Reads standard export formats — not tied to any one modelling tool
  • Quantity summary by section type, grade, and connection category
  • Regional cost index applied for a market-rate cost forecast

Expanded Code Coverage

In Development

Extend StruxBIM™'s automated checks beyond AISC 360-22, ASCE 7-22, and IBC — adding AISC 341-22 seismic ductility automation and deeper IBC provisions.

  • AISC 341-22: seismic system type, overstrength, and ductility checks
  • Expanded IBC: wind-on-components, combined load combinations
  • Conflict detection when seismic and gravity demands interact

Project Communication Tracking

Planned

Full RFI and submittal lifecycle tracking — open vs. closed, revision approvals, who responded and when — so nothing falls through the cracks between submission and detailing.

  • RFI status board: Draft → Sent → Answered → Closed per project
  • Submittal log with revision history and approval signatures
  • Automatic nudge when an RFI has been unanswered past SLA
