SmartChain Guardian solves a key construction-procurement challenge: monitoring contract compliance across fragmented supply chains. Step 5 of the procurement cycle—contract monitoring—is slow, manual, and reactive. Teams often detect late deliveries, quality failures, or specification mismatches only after delays occur. They also lack tools to proactively identify external risks such as supplier shutdowns, natural disasters, or regulatory disruptions. SmartChain Guardian delivers real-time internal monitoring and external risk detection through a multi-agent architecture built on IBM Watson Assistant, supported by two FastAPI microservices. At the foundation are three specialized sub-agents: • Contract Agent – Extracts delivery terms, quantities, and specifications from contract PDFs. • Warehouse DB Agent – Retrieves receiving logs, quality inspections, and inventory from a Supabase PostgreSQL database. • Risk Monitor – Scans global news (via NewsAPI + LLM classification) to detect supply-chain disruptions affecting materials such as cement, steel, copper, aggregates, and lumber. Two orchestrating agents combine these capabilities: • Internal Contract Monitoring Agent – Cross-checks contract terms with warehouse data to flag late or missing deliveries, quantity discrepancies, and quality-control failures. Produces evidence-based compliance reports. • External Risk-Scanning Agent – Correlates real-world events with specific suppliers, materials, and purchase orders to produce targeted risk alerts. Two backend microservices support the system: Warehouse DB Wrapper – Provides LLM-optimized contract and delivery status endpoints. News API Wrapper – Performs high-recall news search and LLM-based risk classification. This architecture enables proactive risk management, zero-hallucination reasoning, auditable compliance, and automated contract monitoring—reducing manual effort, preventing delays, and improving supplier accountability.
