Our Services

Everything From Detailing to Delivery

Whether you need a full shop drawing package or just connection calcs and PE stamps, our team handles every step — with AI checking quality at every stage.

Structural Steel Detailing

Complete shop drawing packages — anchor bolt plans, beam and column details, connection details, erection drawings, and bolting schedules. Every drawing AI-checked before release.

Learn More

Miscellaneous Steel Detailing

Stairs, handrails, guardrails, ladders, mezzanine platforms, and secondary framing — detailed to IBC and OSHA requirements with automated geometry verification.

Learn More

Connection Design & PE/SE Stamping

Primary and secondary connection engineering with real-time AISC 360, AISC 341 seismic, and Eurocode 3 checks. Stamped by licensed PE/SE engineers in all 50 states.

Learn More

BIM & IFC Export

Federated BIM models at LOD 200–400, IFC 4.x export, and clash coordination packages. Compatible with Revit, Tekla, Navisworks, and any OpenBIM workflow.

Learn More

Estimation & Takeoff

ML-powered quantity takeoff and cost estimation from your structural model. Accurate material weights, fabrication labor, and cost forecasts — before a single drawing is issued.

How We Use AI

AI That Makes Your
Deliverables Better

StruxBIM™ is our internal engineering platform — not software we sell. It runs at two fixed points on every project: at intake, to extract and verify the EOR's design data before our team starts modelling; and before delivery, to check every member and connection against AISC 360-22, ASCE 7-22, and IBC before any drawing goes to you.

Runs at intakeRuns before deliveryInternal — not for sale

Design Drawing Extraction

Vision AI

StruxBIM™ reads the engineer of record's PDF drawings using our AI extraction engine — trained on structural engineering drawings — extracting every member designation, grid line, connection type, and dimension into a verified data layer before our team starts detailing. Low-confidence extractions are flagged for manual engineer review.

Dual-engine: AI vision model + text extraction

Issue Detection Before Detailing

Rule Engine + AI

A rule engine checks extracted design data for completeness — missing grids, ambiguous members, absent connection details. Our AI model then analyzes for conflicts and constructability concerns. Detected issues are drafted into professional RFI emails to the EOR automatically.

Problems caught at intake, not after steel is cut

Pre-Delivery Drawing Verification

AISC 360-22 · ASCE 7-22 · IBC

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

99.7% code check accuracy

Accurate Estimates from the Model

Engineer-Verified

Our engineers extract material weights, bolt counts, weld lengths, and fabrication complexity directly from the structural model and apply regional cost data for an accurate BOM and cost forecast — before drawings are issued so there are no budget surprises at bid time.

How our technology works in detail
Why Zenith

Fabricators and Engineers Choose Us for a Reason

Our founders spent years in structural steel at other firms — detailing, designing connections, and watching the same preventable errors cost clients time and money. In 2026, we left to build something better. StruxBIM™ is the platform we built in stealth before we ever took on a client. We opened to customers in 2026 and our first projects came back with zero revision cycles.

Licensed PE/SE Engineers on Every Project

Connection calculations reviewed and stamped by licensed engineers registered in all 50 states. Multi-state projects handled with consolidated packages.

AI Catches What Manual Review Misses

Our AI platform scans every drawing for 80+ categories of common detailing errors — missing dimensions, incorrect edge distances, weld access conflicts — before any drawing leaves our desk.

Files Your Fabricator Can Open Directly

We deliver DXF, IFC 4.x, PDF, and Excel BOM. No format conversion on your end — files open natively in Revit, Tekla, AutoCAD, STAAD.Pro, or Excel.
