CO Risk Sentinel is a predictive claims and dispute analytics layer for large contractors, insurers, and sureties monitoring project change risk. Today, disputes around COs and scope changes are spotted only when lawyers arrive, long after patterns were visible in logs, RFIs, and meeting minutes. Risk Sentinel ingests data from project management platforms, email, field apps, and scheduling tools, then uses LLMs plus pattern recognition to flag emerging claim scenarios (constructive acceleration, cardinal changes, cumulative impact) early. It creates a risk score per project and per owner, with explainable factors and recommended interventions. - Early-warning dashboards for execs, sureties, and carrier claims teams tied to CO density, response times, and dispute language. - Playbook recommendations (e.g., documentation checklists, formal notices) tuned to contract type (AIA, NEC, FIDIC, bespoke). - Benchmarking across portfolios to show which PMs/owners drive higher claim rates and why. - Evidence pack builder that auto-compiles COs, RFIs, schedules, and correspondence into chronologies for negotiation or mediation.
