ClauseChain is a contract-aware change-order copilot for subcontractors and specialty trades navigating complex GC and owner forms. Trade PMs regularly sign master subcontracts and then struggle to align CO language, notice deadlines, and backup with those terms, leading to rejected or underpaid COs. ClauseChain ingests the prime contract, subcontracts, and project-specific exhibits, then sits inside Outlook/Gmail and Procore to flag risk and non-compliance in real time as PMs draft COs or respond to directives. It suggests wording, attachments, and timelines that match client-specific requirements and local lien/notice laws. - Dynamic playbooks per GC/owner that encode “what gets approved here” based on historic outcomes. - Deadline watchdog that monitors written notice and pricing windows and alerts field/office when they’re at risk. - Jurisdiction-aware templates that auto-bake in lien, bond, and delay language appropriate to state/country. - Negotiation assistant that proposes redlines and alternative wording to preserve entitlement while staying within relationship norms.
