ChangeGuard eliminates scope gaps and contractual blind spots in construction projects before they become costly change orders, disputes, or delays.

We perform pre-construction risk analytics — performing cross-document analysis (drawings ↔ contract ↔ scope sheets) in minutes that takes senior estimators 40–80 hours manually.
From a single upload, ChangeGuard surfaces hidden financial exposure, drafts professional RFI language, and scores risk across 10 categories:

Omission, Ambiguity, Inconsistency, Interface/Coordination, Assumption/Risk, Compliance, Quantity/Measurement, Temporal/Scheduling, Responsibility/Resource, and Optimization.

Key results:

10× faster than manual review
Financial exposure quantified ($low–$high ranges)
Fully traceable findings with cryptographic provenance (VeriTrail + Merkle proofs)
Professional RFI-ready language included
Multi-pass verification + 10 hallucination pattern checks

Built for General Contractors (preconstruction managers & chief estimators), Subcontractors, and Owners who refuse to eat avoidable costs. Scope gaps discovered during construction cost 5–10× more to fix — we catch them in preconstruction.

Current status: Piloting with select GC teams. Enhanced architecture (multi-agent LangGraph, LazyGraphRAG, neurosymbolic Z3 verification, conformal prediction) targets 99%+ recall.
