InfraCO Watchtower is an AI-native change-order oversight system for public infrastructure agencies (DOTs, transit authorities, municipalities) that face political and audit pressure over overruns. Today, agency engineers and consultants manually review thousands of COs per megaproject, often buried in PDFs and scanned attachments, making pattern detection and public reporting nearly impossible. Watchtower ingests all contract documents, inspector reports, contractor COs, and meeting minutes, then classifies and explains each change by root cause (design error, unforeseen conditions, scope addition, utility conflict, etc.). It generates dashboards for leadership and open-data summaries for the public. - Compliance checks against procurement rules, funding-source requirements, and internal policies. - Root-cause analytics across projects to feed back into design standards and procurement language. - Public-friendly reporting that turns technical CO logs into understandable visuals on why costs/time changed. - Anti-fraud signals that spotlight anomalous patterns in pricing, timing, and approval paths for audit teams.
