Deterministic Construction Intelligence

Every decision
should have
a receipt.

Lithic transforms BIM data into auditable, replayable and trusted construction decisions.

From model coordination and specification through procurement and delivery.

Construction projects generate thousands of decisions.

Most cannot be explained.

Lithic creates a complete chain of evidence from source model to final outcome.

Chain of Evidence

Every decision
should have a receipt.

Lithic creates a complete audit trail from source model to final outcome.

Every decision can be verified.

Cryptographic signatures bind input, rule version and output into a single auditable artifact.

Every result can be replayed.

Replay tokens reproduce identical outcomes for any past decision, on demand.

Every assumption can be traced.

Semantic contracts expose the exact inputs, defaults and constraints behind each result.

Engine, Not Opinion

Not AI Opinions.
Engine Decisions.

AI can interpret project information.

Lithic determines outcomes using deterministic rules, semantic contracts and auditable decision pipelines.

The same input always produces the same result.

Audience

Built for construction teams
that need proof.

Design

Coordinate models, validate intent against deterministic constraints — without abandoning fidelity.

Validate

Trace every calculation back to its source rule, model element and contract version.

Procurement

Replay any quantity, any specification, any decision — long after the model is locked.

Delivery

Bind product specifications to receipts that survive install, inspection and handover.

Operations

Receive a verifiable record of decisions made on your asset, from concept to operation.

Make decisions explainable

Construction runs on decisions.
Make sure yours are explainable.
