This workflow automates a high-stakes, repetitive bottleneck: manually cross-referencing supplier material specs against hundreds of municipal building codes. The operational upside is direct cost avoidance—eliminating the risk of failed inspections, rework, and project delays that can erase 5-15% of a project's margin. It replaces a fragmented, error-prone process involving PDFs, spreadsheets, and manual portal checks with a deterministic, auditable system. Implementation requires integrating with BIM tools (like Revit or Navisworks), supplier APIs, and municipal code databases, using orchestration frameworks like LangGraph to manage state and exceptions.
