01
Bring the project in
Start with PDF drawing sets, CAD/BIM data, schedules and specifications, then tell EngCalcs what you need designed.
AI-native engineering workspaceBuilt for Australian practice
Bring the project. EngCalcs understands, calculates and keeps it current.
EngCalcs interprets drawings, CAD/BIM data and engineering intent, turns them into a structured project model, then plans and runs the calculation chain. When the design changes, EngCalcs traces the impact and re-runs affected calculations for engineer review.

From project information to engineering output
Understand the design. Calculate it. Keep it current when the design changes.
EngCalcs uses AI to interpret project information, reconcile it into a structured engineering model and decide what needs to be designed. When source geometry or specifications change, the dependency graph shows what is affected and the relevant calculation chain can be re-run. The maths remains deterministic, versioned and reviewable.

02
AI builds the project model
EngCalcs extracts geometry, member tags, levels, materials, openings, notes and relationships, then reconciles them across drawings and models.
03
AI plans the design workflow
The AI identifies design tasks, chooses the required calculation engines, maps dependencies and asks only for missing or uncertain inputs.
04
Deterministic engines run
Standards-based engines execute the engineering maths. Results do not rely on LLM arithmetic.
05
Revisions propagate
When architectural or model data changes, EngCalcs identifies affected inputs, marks dependent calculations stale and re-runs the calculation chain for review.
06
Engineer reviews and issues
Inputs, assumptions, references, formulas, warnings, revisions and provenance remain visible before anything is issued.
Drawings, CAD and BIM
The project model should not care where the geometry came from.
EngCalcs is designed around a common internal engineering model. PDF drawings can be interpreted visually and geometrically, while CAD/BIM sources can contribute richer object, property and relationship data.

Cross-source reasoning
A beam is more than a line on one drawing.
EngCalcs can combine information from several project sources before deciding what a structural element actually supports.

The calculation graph
The model and calculations stay connected.
Once EngCalcs understands the project, the design becomes a graph of sources, extracted facts, assumptions, calculations and downstream dependencies.
- Every extracted value can retain its drawing/model source
- AI identifies the calculation modules required for each design task
- Outputs become typed inputs to downstream calculations
- Architectural and model revisions identify affected calculations automatically
- Dependent calculations can be re-run against the revised design

Why AI belongs here
AI handles interpretation and coordination. Code handles engineering maths.
The useful AI work happens before and around the calculation: understanding project information, reconciling sources, identifying missing data, decomposing the design and coordinating linked calculations.
01
Multimodal project understanding
AI combines drawing text, geometry, schedules, notes and model objects instead of treating each page or file in isolation.
02
Cross-sheet reasoning
Architectural, structural and roof information can be reconciled to understand what an element is actually supporting.
03
AI workflow planning
EngCalcs decomposes the design problem into the calculation chain required to solve it.
04
Deterministic calculation engines
The AI never invents the final engineering maths. Versioned engines execute the standards-based calculations.
05
Revision-aware design
Architectural and model revisions are compared against the project model so EngCalcs can identify which calculations are affected and re-run the dependent chain.
06
Connected calculation graph
Outputs from one calculation become typed inputs to the next, preserving source and dependency information.
07
Transparent review
Every extracted input, assumption, formula, warning, reference and override remains reviewable.
Deterministic calculation engines
The AI does not get to make up the maths.
Each calculation engine is versioned, standards-referenced and independently reviewable. EngCalcs orchestrates them as one workflow while preserving the workings. Wind, steel, concrete, timber and hydraulic calculation engines are already available.

For engineering teams
AI assistance without giving up reviewability.
Engineers remain responsible for the design. EngCalcs gives teams a consistent way to understand project information, plan, calculate, review and issue work while keeping assumptions, overrides and provenance visible.
