fig. 02 · the problem

SharePoint holds files. It does not control documents.

Engineering documents scatter across SharePoint sites and shared drives. Nothing applies a number, nothing marks which revision is controlled, and a Word or Excel file has no history at all. When compliance asks who approved a document, and against which revision, the answer is an email thread.

Lunr is an engineering document management system built for control. Every document is numbered, versioned, and workflow-driven, and every change lands on an audit trail you can hand to an auditor.

On a shared drive5 gaps
  • 01The same specification exists in three folders, and no one is sure which copy is the controlled one.
  • 02There is no numbering scheme, so an as-constructed PDF and its Word method statement carry unrelated names.
  • 03Approvals happen in email, and nothing records who signed off a document, or against which revision.
  • 04A Word or Excel file keeps no revision history, so an edit overwrites the last version with no way back.
  • 05When an auditor asks for the controlled copy and its full history, the answer is a folder and a hopeful guess.
fig. 03 · controlled documents and numbering

One numbering scheme, every format under control.

Book any document in and Lunr applies your numbering scheme, reads title-block tags into its metadata, and starts a revision history. A DWG, a PDF, a Word method statement, and an Excel schedule all sit under the same document control, each with a number, a discipline, and a current revision.

  • Automatic document numbering, applied to your register format as documents are booked in.
  • DWG, DGN, RVT, PDF, IFC, Word, and Excel, all held as controlled documents under one scheme.
  • Title-block and metadata tags read into each document, so you do not retype the number, discipline, or revision.
  • A full revision history on every document, with the superseded copy kept and marked, never overwritten.

fig. 04 · workflows and audit

Configurable workflows, on an audit trail that writes itself.

Run each document through a configurable workflow, from draft to review to approved, with the right reviewers on every stage. Every transition, tag change, and validation is written to an audit trail, so you can show who approved a document, against which revision, and when.

  • Configurable review and approval workflows, with reviewers and assignees set per stage.
  • Every workflow transition recorded, so an approval is tied to a named person and a revision.
  • A full audit trail on every controlled document, filtered by lifecycle, revisions, or validation.
  • Export the record at any time for an ISO 19650 or compliance audit.

fig. 05 · search

Find any document by the words inside it.

XRAY runs OCR and full-text search across every document, so a search reaches inside a scanned PDF, a Word specification, an Excel schedule, and a CAD sheet alike. Search a document number, an asset tag, or a clause, and Lunr returns the controlled copy, whatever format it lives in. Deep XRAY re-scans a dense drawing tile by tile, so nothing is missed.

  • OCR and AI full-text search across DWG, PDF, Word, Excel, and scanned images.
  • Find a document by a number, a tag, or a phrase printed inside it, not just its file name.
  • Deep XRAY re-scans a dense sheet tile by tile, so no note on the drawing is missed.
  • Filter by metadata, discipline, tags, and revision to narrow a large register fast.

fig. 06 · transmittals and handover

Issue transmittals, and take handover complete.

Issue tracked transmittals that record what went out, to whom, and against which revision. Validate every handover and submittal package against a manifest, so a missing O&M manual or as-constructed drawing is caught on upload. Turn a redline into a change request or an RFI without leaving the browser viewer, no native application needed.

  • Issue tracked transmittals, with a record of every document sent and received.
  • Validate handover and submittal packages against a manifest, so a gap is caught on upload.
  • Raise change requests and RFIs straight from a redline in the browser viewer.
  • Review DWG, PDF, and models in the browser, with no CAD licence and nothing to install.

fig. 07 · connectors and security

One document record, connected and secured.

Lunr holds the controlled record while your other systems run their own jobs. Read and write CAD through the connector APIs, tie documents to Esri GIS, and connect the facilities systems that run the estate. Staff sign in over SAML, external parties join as Collaborators, and your instance is hosted in Australia or the US. Every capability is included as standard, with pricing shaped to your organisation.

CAD read-write APIs

Read and write DWG and DGN through the connector APIs, so your CAD stays in step with the controlled record.

Esri GIS and ArcGIS

Tie documents to their place on the network, and open the controlled copy straight from the map.

Facilities and space

Connect Archibus, MazeMap, and SISfm, so the systems that run the estate share one document record.

SAML and OneDrive

Sign staff in over SAML with your identity provider, and bring documents in from OneDrive.

See every CAD, GIS, and facilities connector on the connectors page.

fig. 09 · questions

Questions teams ask about engineering document management.

What an EDMS is, how it differs from SharePoint, and what it takes to move your documents across.

01
What is an engineering document management system (EDMS)?
An engineering document management system, or EDMS, is software that holds an organisation's controlled engineering documents in one record, with document numbering, revision control, review workflows, and a full audit trail. It covers every format an engineering team produces, from DWG and PDF to Word and Excel, and replaces folders on a shared drive with a register where the current revision is clear and every change is logged. Lunr is an EDMS with more than 10 million documents under management.
02
How is an EDMS different from SharePoint or a shared drive?
SharePoint stores files. It does not apply a numbering scheme, it does not know which revision is controlled, and it keeps no audit trail of who approved a document. An EDMS adds document numbering, revision control, configurable approval workflows, XRAY full-text search, and a log of every change. The University of Canberra moved more than 20,000 documents off SharePoint onto Lunr for exactly this reason.
03
What file formats does an EDMS need to handle?
An EDMS should hold every format an engineering team produces, beyond CAD alone. Lunr keeps DWG, DGN, RVT, PDF, and IFC under revision control, along with Word and Excel, and treats each one as a controlled document with a number, a discipline, and a revision. You view drawings, models, spreadsheets, and documents in the browser, and search the text inside every format, scans included.
04
How does document numbering and revision control work?
Lunr applies your numbering scheme as each document is booked in, and reads title-block and metadata tags into the record so you do not retype them. Every document carries a full revision history. When a revision is superseded, the earlier copy stays on the record, numbered and marked, so no one mistakes it for the controlled version. Compare two revisions side by side, or overlay them to see what changed.
05
How do approval workflows and audit trails work in an EDMS?
Run each document through a configurable workflow, from draft to review to approved, with reviewers and assignees set for every stage. Each transition is recorded against a named person and a revision, so an approval is never a line in an email thread. A full audit trail sits behind every controlled document, filtered by document lifecycle, revisions, or validation, and you can export it for an ISO 19650 or compliance audit at any time.
06
Can you migrate documents from SharePoint or an existing system?
Yes. Import documents in bulk, and Lunr reads title-block tags from each drawing and the metadata on each file into the record, so numbering and discipline are populated as documents come in. Your numbering scheme applies automatically. Export all metadata, documents, and models whenever you need to, so the record stays yours.
07
Where is an EDMS hosted, and how is it secured?
Lunr is hosted in Australia and the US, and your instance sits in the region you require. Staff sign in over SAML with your identity provider, external parties join as Collaborators with controlled access, and every controlled document carries a full audit trail. More than 10 million documents are under management on Lunr today.
