Gnosis is cloud-based contract administration software for civil engineering and construction teams in New Zealand, Australia, and the United States. It centralizes contracts, schedules of rates, payment claims and certificates, variations, extensions of time, RFIs, notices, NCRs, transmittals, subcontracts, purchase orders, programmes, reports, timesheets, and audit history. Jurisdiction-specific rulebooks apply contract terminology, working-day calendars, tax, retention, and approval requirements for NZS 3910, AS 4000, and AIA/EJCDC workflows. Gnosis Intelligence can extract data from contract documents and spreadsheets, flag over-claims and deadline risks, and draft documents for human review. Contractors, principals, and reviewers can be invited to scoped contract records.
