Fluvial Knowledge Base

Document control, built for construction professionals. Fluvial replaces the shared drives, email chains, and revision spreadsheets that engineering, design, and site teams use to manage drawings, specifications, and reports — with one web-based system that knows how construction document control actually works.

Why teams choose Fluvial

  • Purpose-built for construction document control — document numbers, revisions, document types, transmittals, and approval sign-off work the way the industry expects, not like a generic file store.
  • Automatic metadata extraction — on upload, Fluvial reads the drawing title block and pre-fills the document number, name, and revision for you to confirm. Anything it can't read confidently is left for you to enter.
  • A single source of truth — every document has one authoritative current revision; superseded and withdrawn versions are retained but clearly marked.
  • Approval-gated issuing — a transmittal cannot be issued until every approval role your account requires (if any) has signed off.
  • Immutable transmittals with a full audit trail — issued transmittals are permanent snapshots, every significant action is logged, and the register exports to PDF and Excel.
  • Unlimited users on every plan — pricing is by active projects, never per seat. Recipients don't even need an account.
