CivilStream is a construction closeout document management platform. It helps general contractors and builders collect warranties, lien waivers, and certificates of insurance from subcontractors. AI automatically extracts key details, tracks expirations, and keeps everything audit-ready.

How does CivilStream work?

Subcontractors submit documents through a simple portal or email. CivilStream automatically extracts key information like contractor names, expiry dates, coverage limits, and amounts. You get alerts before documents expire and dashboards showing who's compliant and who's missing paperwork.

Who is CivilStream for?

CivilStream is built for general contractors, commercial builders, and construction project managers who need to collect and track closeout documents from subcontractors. It's ideal for teams tired of chasing paperwork and managing compliance in spreadsheets.

What documents does CivilStream handle?

CivilStream handles warranties, lien waivers (conditional and unconditional), certificates of insurance (COIs), and other closeout documents. Automatic extraction works on PDFs, photos, and scanned documents.

Is my data secure with CivilStream?

Yes. Each company gets a private database and isolated storage. Your data is stored securely in a private environment with no cross-company access. We maintain audit trails for compliance.
