A Procore alternative built for the owner’s engineering record.
For the asset owners and document controllers who keep the operating record long after the build closes. Hold every drawing under revision control in one register across the asset’s whole life, validate each handover as it arrives, and search the text inside scanned sheets. Keep Procore for the construction project.

Procore is strong software, for the job it was built for.
Procore runs construction delivery well. It coordinates the builder, the subcontractors, and the consultants, tracks RFIs, submittals, and financials, and keeps the site moving. Plenty of teams should keep it for that. The claim here is narrow. Procore is built around the construction project, and an owner operating an asset for decades needs a document record that outlives any one build.
Lunr is built for the owner’s operating record. It holds the controlled drawing set across every project on the asset, while Procore runs the build.
Read why owners keep a permanent drawing record- Coordinating the build, with RFIs, submittals, and the day-to-day between builder, subcontractors, and consultants.
- Construction financials, budgets, change orders, and pay applications.
- Quality and safety on the active site, with inspections and observations.
- Schedule and field productivity while the project is being delivered.
Where a PM suite hits the edge of the owner’s record.
These are the specific points where a construction project management suite stops matching what an owner’s operating record needs. Each one is a job the operating record requires and a delivery platform was never meant to do.
Procore and Lunr, capability by capability.
A factual read of what each tool does for the owner’s document record. The two are not rivals for every row. Procore runs the construction project, and Lunr holds the controlled record for the asset’s operating life.

One register over the asset, not a document set per project.
Book a drawing in and Lunr numbers it, keeps its full revision history, and marks the previous revision as superseded. The register spans every project that touches the asset, so the current revision of every sheet sits in one controlled view, and the title-block fields come across as searchable metadata.
- One controlled register across the asset's whole life, showing the current revision and status of every sheet at a glance.
- Automatic document and version numbering, applied in your register format as drawings are booked in.
- Superseded revisions kept and marked, never deleted and never mistaken for the current sheet.
- Title-block tags read into metadata, so the drawing number, revision, and discipline become filters.

Open a DWG, DGN, or RVT in the browser, no CAD licence.
Procore views current construction drawings in its built-in viewer. An owner’s record holds more than that. In Lunr the Rift viewer renders DWG, DGN, and PDF at full fidelity, with layers, measurement, and markup, and it opens the legacy formats the asset carries as well. Models open in Foundry, point clouds in Nimbus.
- View DWG, DGN, RVT, and PDF in the browser, with no CAD licence and nothing to install.
- Toggle layers, measure, and mark up the drawing straight in the viewer.
- Open BIM models in Foundry and point clouds in Nimbus from the same record.
- Turn a redline into a change request or an RFI without leaving the viewer.

Search the words printed inside a scanned drawing.
An owner’s archive holds decades of scanned drawings that predate any construction platform. Procore captures metadata on the documents flowing through a project, but the text drawn inside a scanned sheet stays invisible to a search built around project documents. XRAY runs OCR and full-text search across every drawing, scans included, so a valve tag on a 1994 sheet is as findable as one saved this morning.
- OCR and AI full-text search across every DWG, DGN, RVT, PDF, and scanned image.
- Find a tag, a reference, or a note printed inside the drawing, not just the file name.
- Deep XRAY re-scans a dense sheet tile by tile, so nothing on the drawing is missed.
- Filter results by metadata, tags, and revision to narrow a large set fast.

Validate the handover on arrival, keep the audit trail for the asset’s life.
Procore packages the closeout record and exports it to an FM or CMMS system. Lunr sits on the receiving side. It validates each handover package against a manifest, so a missing as-constructed drawing is caught on upload rather than years later, issues tracked transmittals on the operating record, and keeps a full audit trail behind every approval, revision, and change.
- Validate each handover package against a manifest, and read title-block tags into metadata.
- Issue tracked transmittals, and run change requests that hold, forward, and close.
- Move drawings through configurable review and approval workflows.
- Keep a full audit trail on every controlled drawing, ready for compliance.

Bring the record across, keep Procore for the build.
You do not have to wait for a project to close or rebuild anything. Receive the handover and validate it, import the legacy back-catalogue, and read the title blocks into metadata. The owner’s record moves to Lunr, and Procore keeps running the construction project.
- 01Receive the handover
Point Lunr at the Procore closeout export and it validates the package against a manifest, so a missing as-constructed drawing is caught on upload rather than years later.
- 02Import the back-catalogue
Bring in the decades of scanned drawings that never lived in the project, and XRAY reads the text inside each sheet so the whole archive becomes searchable.
- 03Read the title blocks
Lunr reads the title-block tags from each sheet into metadata, so drawing number, revision, and discipline become fields you filter on, without retyping.
- 04Keep Procore for the next build
Run Procore for the active construction project and Lunr for the owner's operating record, side by side. Nothing forces an all-or-nothing move.

Questions owners ask about Procore and the engineering record.
What a construction PM suite does and does not do for an owner’s document record, and what it takes to bring the record across while Procore keeps running the build.
- Is Lunr a Procore alternative?
- It depends on the job. Lunr is not a replacement for construction project management. Procore coordinates the build, and it is good at that. Where owners reach for an alternative is the document record. A construction PM suite organises documents around the project being delivered, and an owner operating an asset for decades needs a controlled engineering record that outlives any one build. Lunr is that record, and most owners run it alongside Procore rather than in place of it.
- What is the difference between Procore and Lunr?
- Procore is a construction project management suite, and document management is one module inside it, tuned to delivering the current project. Lunr is purpose-built engineering document control for the owner's operating record. The difference shows up at the edges. Procore's register is shaped around a project, Lunr's spans every project that touches the asset. Procore exports the handover at closeout, Lunr receives and validates it. Procore captures metadata on project documents, Lunr runs OCR across the scanned back-catalogue that predates any project. Neither replaces the other, because they do different jobs.
- Can you use Lunr alongside Procore?
- Yes, and it is the common setup. Run Procore for the active construction project, with its RFIs, submittals, and financials, and keep Lunr as the owner's system of record. When a project reaches handover, the closeout package flows from Procore into Lunr, where it is validated against a manifest and booked into the controlled register. Procore keeps doing what it is good at, and the owner's record has a permanent home.
- What happens to drawings when a Procore project closes?
- At closeout Procore packages the record and exports it in PDF, Excel, or Zip, ready to load into an FM or CMMS system. That covers the transfer, but it leaves the owner with a static export rather than a living record. Lunr is where that package lands. It validates the handover on arrival, holds every sheet under revision control, and keeps the register current as later projects revise the asset, so the drawings stay live instead of sitting in an archive folder.
- How does Lunr validate a handover from Procore?
- Lunr checks each handover package against a manifest, so a missing as-constructed drawing is caught on upload rather than surfacing years later when someone needs the sheet. As the package lands, Lunr reads the title-block tags from each drawing into metadata, applies your register numbering, and records the whole transfer as a tracked transmittal with a full audit trail. The gap is found while the delivery team is still on hand to close it.
- Does Procore handle the owner's operating record after handover?
- Procore is built around the construction project. Its asset register and integrated handover package warranty and maintenance data for transfer, and its 400-plus integrations move that data into FM and O&M systems. What it does not set out to be is the owner's permanent engineering document control system across the operating life of the asset. For that, owners move the controlled drawing record onto a purpose-built system and keep Procore for delivering the next build.
- Can Lunr search inside scanned legacy drawings?
- Yes. XRAY runs OCR and full-text search across every drawing, scanned sheets included, so the text drawn inside a sheet is searchable, not just the file name or its metadata. This matters most for the back-catalogue an owner has carried for decades, the drawings that predate any construction platform. Search a valve tag, a title-block reference, or a note, and Lunr returns the sheet whether it was scanned from a 1994 archive or saved this morning.
Keep Procore. Give the record a home.
