Method-Driven Modules

Every module solves a specific pain

Six specialist modules, each aimed at a concrete problem in the structural workflow. Tenzor orchestrates them — or bring your own orchestrator (Claude Code, Copilot, Codex, or any MCP-compatible client).

Available

Tenzor

Workflow orchestrator

The pain

You juggle Excel, Tedds, Mathcad, ETABS, email, and Bluebeam across every project. You retype the same values between tools. Your firm’s standards live in a senior engineer’s head — you re-explain them to every new junior, every project.

What Tenzor does

One conversational interface that coordinates your specialist modules with your approval on every step, and remembers your preferences and firm standards across every project.

  • Stop retyping values between tools
  • Standards and preferences persist across projects
  • Human approval before anything runs
  • Drives from your browser or your IDE

CalcModule

Computation engine

The pain

Every junior rebuilds the same ACI, ASCE, and AISC checks from scratch. PEs burn review time catching basic scope errors instead of exercising engineering judgment. Spreadsheets drift firm-to-firm and person-to-person.

What CalcModule does

Validated calculators that show every equation, cite the provision they implement, and declare exactly what they cover and do not cover. Project parameters auto-propagate across a package.

  • Validated methods per code edition
  • Scope statements on every calculator
  • Basis of Design auto-fills downstream calcs
  • Consistent PDF output across the firm

DocModule

Deliverable package builder

The pain

Two hours in Acrobat on every calc package — cover pages, tables of contents, page numbers, re-ordering sections. Another two hours on every revision. Formatting drifts across project teams.

What DocModule does

One-click PE-ready packages from templates. Cover page, TOC, and external PDFs bundled and paginated automatically.

  • Multi-calc PDF bundling
  • Auto cover page and TOC
  • External PDF integration
  • Drag-and-drop reordering

ModelViewer

Model inspection module

The pain

You open ETABS just to review a model someone else built. Peer reviewers get blocked by license seats. Clients and project managers cannot preview what you built without installing the software.

What ModelViewer does

Browser-based 3D model review. Open any ETABS .e2k file without opening ETABS.

  • 3D model in the browser, no install
  • Section / material / load display modes
  • No extra ETABS seats for reviewers
  • Shares import cache with AuditModule

Available

AuditModule

Review and analysis kernel

The pain

PEs hunt for the same mistakes in every ETABS model — drift, torsion, irregularities, missing diaphragms. Some mistakes reach construction anyway. Junior engineers do not know what to check first.

What AuditModule does

An automated QA/QC pass that runs before the PE opens the model. 36 domain rules with code citations, statistical anomaly detection per element class, and LLM cross-validation — surfaced as a narrative report with a 3D heatmap.

  • Catches scope errors before the PE sees them
  • Code citations on every finding
  • Statistical outliers flagged per element class
  • Narrative report plus 3D anomaly heatmap

Available

ImportModule

Import module

The pain

Tier 1 reports arrive as scanned PDFs — someone re-keys deficiency lists, cost estimates, and metadata into the project template. Large ETABS models crash the browser. Geotech reports sit unread on a shared drive.

What ImportModule does

LLM extracts structured findings from PDF reports. Multipart streamed upload handles ETABS models up to several gigabytes. Downstream modules load the extracted data on demand.

  • LLM Tier 1 report extraction
  • 200 MB to 5 GB .e2k upload
  • Background parsing, no browser blocking
  • Shared cache feeds ModelViewer and AuditModule

The Assurance Stack

Trust infrastructure under every calculation

Four layers that make AI-assisted engineering output legally defensible and PE-stampable. Not aspirational. Shipping today.

Available

Method-Encoded Calculators

Every calculator explicitly implements code methods with cited provisions and scope statements — "this calc covers / does not cover". Code editions (ACI 318-19, ASCE 7-22, AISC, ASCE 41-23, ASME A17.1) are tracked as first-class metadata on every run.

Available

Engineering Safety Net

Post-execution consistency checks, range-catalog validation, and cross-calculator conflict detection run automatically after every calculation. Findings surface inline with suggested fixes.

Available

PE Review Workflow

Multi-round reviews with inline comments, reviewer checklists, notifications, and a persisted audit trail of every round. Approved calculations carry a digital signature block on the PDF.

Available

Audit-Grade Governance

Append-only audit records on every calculation run. Scope statements on every calculator. Code-edition and assumption fields tracked on every result. Immutable history built for deposition-grade defensibility.

Dual-Channel Distribution

Work in your browser. Or in your IDE.

Every module, calculator, governance rule, and Safety Net check works identically from both channels. No feature is built for only one surface.

For AEC professionals

Brain Web UI

Zero installation. Looks like chat, ships like an engineering platform.

  • Natural-language chat with human-in-the-loop approval
  • 3D model viewer with anomaly heatmap
  • Drag-and-drop package composer
  • Inline PE review with audit trail
  • Project memory that learns your preferences

For power users

MCP in your IDE

Any MCP-compatible client can drive the same tools via API-key scoped access.

  • list_calculators, get_schema, run_calculation
  • list_projects, search_memory, add_memory
  • list_packages, run_package, get_report_pdf
  • API-key scoped per-module entitlements
  • Works in Cursor, Claude Code, Codex, any MCP client
Get an API key

Both channels authenticate against the same project, memory, and audit trail. Switch mid-project; every action is logged to the same immutable record.

Research Preview — Design Partners Welcome

Design Studio —
From architectural intent to structural options

The next major capability we're building on the Tenzor trust stack. Upload 2D architectural drawings or an existing structural model. Get a 3D BIM with provenance, multiple structural scheme options — gravity and lateral systems sized for your seismic zone — ranked by cost, embodied carbon, structural depth, and schedule. Your judgment, amplified by an options engine that never skips the code check.

Multimodal ingestion

PDF / DXF / IFC / Revit plans parsed into an IFC 4.3-aligned BIM. Every element carries provenance back to the source drawing.

Generative schemer

Proposes scheme families (SCBF, BRBF, SMF, PT + shear wall, CLT, base-isolated) filtered by ASCE 7-22 system, height, and SDC rules.

Analysis ladder

T0 closed-form triage across thousands of options. T1 surrogate for ranking. T2 OpenSeesPy or ETABS round-trip only on the final 3–5.

Options engine

Pareto ranking across cost, embodied carbon, structural depth, schedule, and code-margin reserve. Every accepted scheme passes a deterministic code check.

Upload architectural plans

Get a 3D BIM and multiple structural scheme options sized for your seismic zone. Mark up where columns and shear walls should go — drawn in-canvas or imported from Bluebeam.

Upload an existing structural model

Round-trip with ETABS / SAP / RAM / RISA / STAAD. "Keep the gravity, explore the lateral." "Find a lower-carbon variant at equal performance." "Evaluate this design under ASCE 7-22."

Frequently Asked Questions

Common questions about Tenzor Intelligence, engineering modules, and how we handle codes.

Because each one has a defined method, deterministic behavior where it matters, and engineering accountability attached. "Agent" implies autonomous AI behavior; our modules are validated computation with human-in-the-loop approval on every step. The word "module" maps to engineering practice; "agent" maps to AI hype.
