Engineering document management software, surveyed for asset owners.
Thirteen products, in alphabetical order, each written the same way: the job it is genuinely good at, then how it sits against an asset owner’s drawing record. Lunr is one entry among them. Most of these tools were built for a design office, a delivery team, or the wider business, and the good ones are very good at that work.

13 products · what each is built for · where the drawing record fits
Six questions that decide where a drawing record lives.
Feature lists converge, and demonstrations run on clean data. These six axes separate the products that can hold an owner’s record from the ones that store its files. Put each question to every vendor on your shortlist, and test the answers against your own drawings.
Ask what happens to the superseded sheet, and whether an approval is tied to a named person and a revision rather than an email thread. A version history on a file is not the same as a controlled revision on a drawing.
Ask which of DWG, DGN, RVT, IFC, and PDF open without a CAD licence, whether external references resolve, and whether layers, measurement, and markup work for someone who has never held a CAD seat.
Most owners hold decades of sheets scanned from paper, and a scan is an image until something reads it. Ask whether search reaches the text drawn on the sheet, then test it on your own worst microfilm scan.
Ask whether an incoming package is checked against a manifest as it lands, so a missing as-constructed drawing or O&M manual is caught on upload rather than found years into operation.
Ask which country holds the data, where backups replicate, and who can reach them. Procurement, regulators, and security policies name countries, and cloud products differ on which regions they offer.
Ask what has to exist before a document controller can find a drawing: a Windows and SQL Server build, a desktop client rollout, managed workspaces, or a configuration programme covering metadata, security, and integrations.
The products asset owners actually shortlist.
Listed alphabetically, not ranked. Several of these are the right answer for a job an owner also has to get done, and running two systems that each do one job well beats forcing one to do both.
- Best for
Civil engineering and surveying offices, particularly those running 12d Model, that need worksharing, large survey datasets, and an ISO 19650 common data environment across the design team. Deploy on 12d's cloud, your own servers, or your own cloud infrastructure.
On an owner’s drawing recordBuilt around the office producing the work, and connected to the drafting and geospatial packages that office runs. Holding a finished set through decades of operation is a different job from worksharing a live project.
- Best for
Multi-party delivery on large capital works, where formal mail, transmittals, submittals, and review workflows have to run across every organisation on the job. Few tools coordinate that many parties as well.
On an owner’s drawing recordEach organisation owns its own data, so the owner holds what was sent to them. When the project closes the environment moves to read-only archive access, and revisions raised during operation need somewhere live to land.
- Best for
Design and construction teams working in the Autodesk toolchain. Autodesk Construction Cloud holds BSI Kitemark certification against ISO 19650, with versioning, status codes, revision identifiers, naming conventions, and permissions built in.
On an owner’s drawing recordStrongest where the project is Autodesk end to end. An owner's archive rarely is: DGN from one consultant, PDFs from another, and thousands of scans that predate both.
- Best for
Design and manufacturing teams authoring in Inventor, AutoCAD, or Revit who need check-in and check-out, dependency tracking across referenced files, and version control over work in progress, with links out to PLM and ERP.
On an owner’s drawing recordVault runs as a client-server product: the Autodesk Data Management Server and its SQL database on a Windows server, with a matching Vault client on each PC. That shape suits an authoring team, and it is heavy for operations staff who only need to open a sheet.
- Best for
Asset owners holding tens of thousands of drawings for decades: universities, utilities, energy companies, and government. The register runs in the browser, XRAY reads scanned sheets with OCR, handover packages are validated against a manifest, and instances are hosted in Australia or the US.
On an owner’s drawing recordShaped for the record after issue rather than the design work that produced it. Lunr does not run live CAD authoring, construction budgets, or field management, and it is a poor choice as a general business-wide content platform. Design firms keep their tools, and the owner keeps the record.
- Best for
Organisations wanting one governed document platform across the whole business, where content is classified by what a document is rather than where it was saved. Microsoft 365 integration is native, and deployment can be cloud, on-premises, or hybrid.
On an owner’s drawing recordA general document management system carries general document machinery. Reading a title block into a register, holding revision conventions on a sheet, opening DWG and DGN in the browser, and running OCR across large-format scans are drawing-specific jobs to ask about directly.

Meridian
Owner-operator EDMS · Accruent
Best forAsset-intensive owner-operators in process industries, where engineering document control has to tie into ERP, EAM, and asset management systems. Meridian Cloud runs on Microsoft Azure, Meridian Enterprise Server covers on-premises deployment, and Meridian Portal handles contractor exchange.
On an owner’s drawing recordA genuine owner-side engineering document management system, and a fair entry on any owner's shortlist. Weigh the implementation: the platform spans several products, and configuration effort scales with that surface.
- Best for
Large regulated enterprises standardising records, retention, permissions, and audit across every content type on one platform, often tied into SAP. Extended ECM for Engineering adds engineering handling on top of that platform.
On an owner’s drawing recordDrawings are one content type among many. The metadata model, security, workflows, and integrations all have to be configured first, so time to a working drawing register depends on that programme rather than on the drawings.
- Best for
Construction delivery. Contractors and owners run drawings, RFIs, submittals, budgets, schedules, and field collaboration in one place, with version control on drawings and a viewer inside the platform.
On an owner’s drawing recordOrganised around a construction project. The operating record afterwards, the archive from before it, and the engineering documents that never belonged to a project sit outside that frame.
- Best for
Engineering design offices coordinating live work in progress, particularly on Bentley toolchains such as MicroStation, OpenRoads, and OpenBuildings. ProjectWise 365 adds browser-based design review, transmittals, and issue tracking.
On an owner’s drawing recordDesign infrastructure brings administration with it: datasources, managed workspaces, and someone to run them. It is scoped to delivery, and an owner needs a record that outlives the project and the firms who worked on it.
- Best for
Office documents, policies, intranets, and general business collaboration. Most organisations already own it, and for Word, Excel, and PowerPoint it does the job well.
On an owner’s drawing recordA library applies no drawing numbering scheme and holds no register, so nothing marks which revision is controlled. CAD files with external references break when opened from a library, and search commonly reaches the file name rather than the text on the sheet.
- Best for
Engineering teams wanting deep desktop CAD integration alongside revision control, automated workflows, and audit traceability, across manufacturing, utilities, mining, and oil and gas. Deploy on your own Windows and SQL Server infrastructure, hosted by Synergis, or on the browser-based Adept Cloud.
On an owner’s drawing recordStrong on the CAD side of the record, and a real shortlist entry for owners. Check how much of what operations, facilities, and contractor users need sits behind a desktop client or a licence tier, and which deployment matches your hosting requirements.
- Best for
Delivery-side document control on large capital projects, and long established across Australian infrastructure, oil and gas, power, and mining. Built by Melbourne's QA Software in 1995, acquired by InEight in 2018, and now branded InEight Document.
On an owner’s drawing recordA project collaboration platform, so the transmittals, mail, and workflows are aimed at a delivery team running a job. The owner's long-lived register and the archive that predates the project need their own home.
Products change. Each entry reflects the vendor’s own documentation and public material at the time of writing, so confirm the detail that decides your case directly with them. Accruent Meridian has no comparison page here yet.
Start from the job, then pick the tool.
Most bad choices in this category come from buying for the wrong job. Find the row that describes what you are actually solving, and shortlist from there.
| The job | Where to look |
|---|---|
| Live design work in progress inside an engineering office | ProjectWise, 12d Synergy, or Autodesk Docs, chosen by authoring toolchain |
| Document exchange across every party on a capital project | Aconex or TeamBinder |
| Construction delivery, budgets, and the field | Procore |
| CAD work in progress with dependency tracking and check-out | Autodesk Vault |
| One governed platform for all business content | SharePoint, M-Files, or OpenText, by scale and regulatory load |
| The owner's drawing record through decades of operation | Lunr, Synergis Adept, or Accruent Meridian |
Owners commonly need two of these rows at once, one for delivery and one for the record. See how the two sit together on the comparisons hub, or read how a controlled record is put together in the document control guide.
Questions buyers ask about engineering document management software.
Which product suits which job, what to test during evaluation, and what implementation actually costs in time.
- What is the best engineering document management software?
- No single product wins every case, because the tools in this survey were built for different jobs. For live design work in progress, ProjectWise, 12d Synergy, and Autodesk Docs lead, chosen by authoring toolchain. For document exchange across every party on a capital project, Aconex and TeamBinder are the usual shortlist. For an asset owner holding the drawing record through decades of operation, the field narrows to purpose-built engineering document management such as Lunr, Synergis Adept, and Accruent Meridian. Decide which of those jobs you are buying for before comparing features.
- What is the difference between engineering document management software and a common data environment?
- Engineering document management software controls documents: numbering, revisions, review workflows, and an audit trail across the drawings and specifications an organisation keeps. A common data environment (CDE) is the shared information space a project team works in through delivery, defined by standards such as ISO 19650. Plenty of products do both to a degree. The practical question for an owner is what happens when the project closes, because a delivery environment has finished its job at that point while the owner's record has decades left to run.
- What should you evaluate when choosing engineering document management software?
- Six things decide it for a drawing record. Revision control: what happens to the superseded sheet, and whether an approval is tied to a named person and a revision. CAD format handling: whether DWG, DGN, RVT, IFC, and PDF open without a CAD licence. OCR of scanned drawings: whether search reaches the text drawn on a 1994 scan. Handover validation: whether an incoming package is checked against a manifest. Hosting jurisdiction: which country holds the data. Implementation effort: what has to be stood up before a document controller can find a drawing.
- Which engineering document management software suits an asset owner rather than a project team?
- Look for products built around a register the owner holds rather than a project that closes. Lunr, Synergis Adept, and Accruent Meridian are all shaped that way, and they differ mainly in deployment and reach. Adept is strongest where desktop CAD integration matters, Meridian where document control has to tie into ERP and EAM systems, and Lunr where the record has to run in the browser with OCR across a legacy archive and hosting in Australia or the US. Project platforms such as Aconex, Autodesk Docs, and ProjectWise remain the right answer for delivery.
- Can SharePoint work as engineering document management software?
- For the Office documents around a project, yes. For a drawing record, it leaves the hard parts to you. A document library applies no drawing numbering scheme and holds no register, so nothing marks which revision is controlled. CAD files with external references break when opened from a library, and search commonly reaches the file name rather than the text drawn on the sheet. Owners usually keep SharePoint for general business content and hold drawings in purpose-built engineering document management alongside it.
- Does engineering document management software need to read scanned drawings?
- For an asset owner, yes. Most owners hold decades of sheets scanned from paper, and a scan is an image until something reads it. Without OCR, a search reaches the file name and whatever metadata somebody typed, which is where an archive goes quiet. Test this during evaluation rather than taking it on trust: load your worst microfilm sheet, search for a valve tag drawn in a corner of it, and see what comes back.
- How long does engineering document management software take to implement?
- It tracks the shape of the product more than the size of the archive. Browser-based systems with bulk import and title-block parsing stand a register up quickly, because the metadata is read from the drawings rather than retyped. Client-server products add a Windows and SQL Server build, a client rollout, and version matching between the two. Enterprise content platforms are a configuration programme in their own right, covering the metadata model, security, workflows, and integrations. Ask each vendor what has to exist before a document controller can find a drawing.
- Where is engineering document management software hosted, and does the jurisdiction matter?
- It matters whenever procurement, a regulator, or a security policy names a country. Cloud products differ: some run in one global region, some let you choose, and some deploy on your own infrastructure. Lunr is hosted in Australia and the US, and an instance sits in the region you require. Ask each vendor where the data is stored, where backups replicate, and who can reach them, and get the answer in writing before you shortlist.
