Document control, on the engineer’s side of the desk.

Replace Excel, email chains, and the “which Rev is current” argument with routed reviews, sealed transmittals, and a hash-chained audit trail your lender will accept. Built for EPC and large-construction across power, infrastructure, building, and renewables.

Free while you pilot · no credit card · setup in under 15 minutes.

Review cycles cut from 14 days to 5.

Any document, found in 18 seconds. Every transmittal sealed with a hash-chained audit trail your lender accepts on the first pass.

Production data · owner@hnt.demo project · not benchmark fiction.

Handle. Navigate. Track.

Three things the platform actually does, named with the verbs your team already uses.

A review route, not an inbox.

Configure who reviews what, in which order, with what SLA — per project, not per document. The route runs itself; reviewers stamp codes (Code 1–4, EN, NE, RJ) and the workflow advances.

Configurable per project. Parallel and serial reviewers. Auto-escalation on SLA breach.

From signed contract to first transmittal in under two weeks.

  1. Spin up the project

    Pick a sector preset. Disciplines, doc types, numbering, and review codes load with it. Owner sets the SLA.

  2. Wire in the team

    Invite the EPC, the checker, the lender consultant. Roles + permissions are configurable per project.

  3. Route the first drawing

    Upload, route, redline, stamp a code, seal a transmittal. The audit chain starts at event #1 and never breaks.

Built for the sectors you deliver in.

Whether you’re running a 90 MW solar farm, a 22 kV substation, a hospital, or a refinery — the workflow is the same: route the drawing, stamp the code, seal the transmittal.
