BIM Data Room

Share Revit, Navisworks, IFC — federated, watermarked, NDA-gated.

A secure data room for BIM coordination — Revit federations, Navisworks NWD/NWF, IFC exports, MicroStation, ArchiCAD, Tekla. NDA gates before any folder loads. Dynamic watermarks tied to viewer identity. Screenshot protection across desktop and mobile. Built for construction handover, AEC client delivery, infrastructure project finance, and construction-litigation evidence. $40 per admin per month on Peony Business — unlimited storage, unlimited rooms, unlimited counterparties.

What is a BIM data room?

A BIM data room is a virtual data room engineered for sharing Building Information Modeling files — Revit federations (.rvt, .rfa), Navisworks coordination files (.nwd, .nwf, .nwc), IFC neutral exchanges, ArchiCAD, Bentley MicroStation, Tekla Structures, COBie handover data — with external counterparties under NDA. The same external-review workflow as a traditional VDR (NDA gates, granular permissions, page-level analytics, audit trails, Q&A) but engineered so federated BIM uploads stay intact (no forced splitting that breaks reference dependencies), with dynamic watermarks tied to viewer identity, screenshot protection, and no download access for confidential coordination files.

Three things break when teams use generic tools to share BIM. First, cloud storage (Dropbox, Box, SharePoint, OneDrive) lacks NDA gates and dynamic watermarks tied to viewer identity, and SharePoint specifically has no native Revit preview and no per-room workspace isolation between client projects. Second, construction-execution platforms (Procore, Autodesk Construction Cloud) are built for day-to-day project workflows — RFIs, submittals, daily reports, BIM clash detection during the build — not for external owner/lender review of finalized handover packages or for litigation-evidence distribution to expert witnesses. Third, per-page legacy VDRs (Datasite, Intralinks) charge $0.60+ per page, rendering 80GB BIM federations as 64,000+ pages and billing $38,400+ in per-page fees alone.

Peony Business at $40 per admin per month delivers unlimited storage with NDA gates before any folder loads, dynamic watermarks stamping every model view with viewer name, email, IP, and timestamp, screenshot protection across desktop and mobile, visitor-group permissions segregating syndicate-bank-A from syndicate-bank-B in the same data room, and full audit trails on every page view.

Which BIM formats does Peony support?

Revit (.rvt, .rfa, .rte) — Autodesk's native BIM
Navisworks (.nwd, .nwf, .nwc) — clash detection and coordination
IFC (.ifc) — neutral exchange (buildingSMART)
ArchiCAD (.pln, .pla) — Graphisoft native
Bentley MicroStation (.dgn) — infrastructure-favored BIM
SketchUp (.skp) — early-design BIM
Tekla Structures (.db1) — structural BIM
Solibri (.smc) — model checking exports
BIM 360 / ACC exports (.zip federations)
COBie (.xlsx, .ifc) — handover data exchange

Federated BIM uploads preserve reference dependencies without forced file splitting. Native preview supported for IFC and most neutral exchange formats; proprietary formats (Revit, Navisworks) preview as PDF exports or download behind NDA gates with dynamic watermarks. Chunked parallel uploads handle individual files into the multi-GB range.

Who uses a BIM data room?

Construction handover & closeout

Owner and lender review of as-built Revit federations, Navisworks clash reports, drone progress videos.

AEC client delivery

Architecture and engineering firms sharing BIM coordination with developer clients under NDA.

Infrastructure project finance

Multi-bank syndicate review of BIM federations, point-cloud surveys, and concession agreements.

Construction litigation evidence

Distribution of as-built Revit, BIM clash reports, and CAD shop drawings to expert witnesses.

Should I use Procore, Autodesk Construction Cloud, or a BIM data room for external review?

  • Use Procore / ACC for active project execution. RFIs, submittals, daily reports, BIM clash detection during the build, subcontractor coordination. These platforms are built around the project-team workflow.
  • Use a BIM data room for external review. Owner handover, lender draw approvals, M&A diligence on AEC firms, claims-evidence distribution to expert witnesses. These workflows require NDA gates, dynamic watermarks, and bidder-track permissions Procore and ACC don't natively offer.
  • Use both. Most $100M+ projects do — Procore/ACC during execution, Peony for handover and external lender/owner review. They're complementary, not competitive.
  • Pricing: Peony Business at $40/admin/month — unlimited rooms across as many active and closed-out projects as you run. NDA gates, dynamic watermarks, screenshot protection, page-level analytics, audit trails included.

When is Peony NOT the right fit for BIM?

Use Procore / Autodesk Construction Cloud / BIM 360 instead if your workflow is active construction project management — RFIs, submittals, daily reports, BIM clash detection during the build, subcontractor coordination, change-order routing. Peony is the external review and handover layer, not the day-to-day project execution platform.

Use Solibri / Navisworks Manage / Revizto instead if your workflow is in-platform model checking and clash resolution. Peony shares finalized clash reports with external counterparties; it doesn't run the clash detection itself.

Use BIMcollab / Trimble Connect for issue-tracking workflows where the value is the comment thread, BCF round-trips, and issue resolution between coordinators. Peony is for sharing finalized models with reviewers under NDA, not for active coordination.

Use a geological data room (see /use-cases/geological-data-room) if your project is dominated by subsurface data — Leapfrog .lfview models, Vulcan resource models, well logs, seismic interpretation. BIM and geological models share workflow patterns but the file types and reviewer audiences differ.

"Peony has been great for sharing documents with investors, employees, and customers. It's easy to use, good value, and new features are constantly being added. Definitely recommend!"

Frequently asked questions

I'm a project executive at a $600M infrastructure GC closing out a transit-station build — owners and lenders want to review Revit federations and Navisworks clash reports. Files are 40GB+. What's the right setup?

For your $600M transit-station handover, Peony Business at $40/admin/month handles 40GB+ Revit federations (.rvt, .rfa, .rte), Navisworks NWD/NWF coordination files, IFC exports, and as-built drone walkthroughs without forced file splitting. Configure visitor groups so the owner sees the full package while each lender syndicate sees only the milestone subset relevant to their tranche. NDA gates require every external reviewer to sign before any model loads. Dynamic watermarks stamp every page (and every video frame in your handover walkthrough) with the recipient's identity. Audit trails log every view with timestamps — useful for project closeout sign-offs. Procore and Autodesk Construction Cloud are built for active project execution (RFIs, submittals, daily reports), not external lender/owner review of the finalized package; use them for the build, Peony for the handover.

I'm a partner at a 12-person architecture firm sharing 80GB of Revit models with developer clients across 6 active projects — how do I prevent client A from seeing client B's BIM data?

For your 12-person architecture firm, Peony Business at $40/admin/month covers 80GB+ unlimited uploads across as many client rooms as you run. Each client gets a separate data room scoped to their project; workspace permissions ensure team members assigned to client A cannot see client B unless you explicitly grant access. NDA gates require each developer client to sign your firm's confidentiality agreement before any model loads. Dynamic watermarks stamp every Revit view, drawing, and rendered image with the client's name and timestamp — useful when a developer leaks a competitor's plans and you need to trace which client room it came from. SharePoint has no native Revit preview and no per-room workspace isolation; Box Enterprise has no NDA gates or dynamic watermarks. Peony's flat $40/admin/month for a 6-admin firm is $2,880/year flat regardless of how many client projects.

I'm an MD at a $2B infrastructure debt fund evaluating a $400M port redevelopment — the sponsor's data room has 80GB of BIM federations, point-cloud surveys, and concession agreements. How do we share with 18 syndicate banks?

For your $2B infrastructure debt fund's port redevelopment evaluation, Peony Business at $40/admin/month handles 80GB+ uploads of Revit BIM federations, Navisworks coordination files, IFC exports, point-cloud surveys (.las, .e57), drone progress videos, traffic studies, and concession agreements with no per-GB surcharges. Configure 18 visitor groups for syndicate banks so each tier sees the diligence subset relevant to their commitment level. NDA gates require every syndicate participant to sign before any folder loads; dynamic watermarks tied to each banker's identity discourage cross-syndicate leaks; page-level analytics show which banks are running rigorous diligence — useful for allocations. Peony's 8-admin fund pays $3,840/year flat across unlimited concurrent deals; Datasite's per-deal pricing for an asset of this size runs $50K-$150K per transaction.

I'm head of M&A at a $1.5B AEC firm acquiring a 200-person MEP consultancy — their book of business is 25 active projects with shared Revit federations. Can we evaluate without violating their client confidentiality?

For your $1.5B AEC firm's MEP consultancy acquisition, Peony Business at $40/admin/month structures the diligence to respect client confidentiality during evaluation. The target uploads project files into NDA-gated visitor groups — your buy-side team signs a binding NDA before any folder loads. Dynamic watermarks stamp every page with your deal team's identity, and screenshot protection blocks captures of client-confidential MEP coordination. Audit trails log every view — useful when the seller's clients ask after close how diligence was handled. For projects where the seller's clients have specific NDAs prohibiting third-party review, those projects can be redacted or excluded entirely; visitor-group permissions handle this segmentation natively. Datasite's per-deal pricing for a transaction of this size runs $40K-$100K; Peony's 5-admin deal team pays $2,400/year flat across this acquisition and every concurrent add-on.

I'm a project superintendent at a $400M GC managing a stadium build — weekly drone progress videos plus BIM federation updates total 60GB+ over 18 months. How do we manage owner reviews?

For your $400M stadium build, Peony Business at $40/admin/month consolidates weekly drone progress videos, milestone Revit federations, Navisworks clash detection reports, and as-built drawings in one room with no per-GB surcharges across the 18-month build. The owner reviews progress against schedule directly in the data room — drone videos preview without download access; dynamic watermarks stamp every page with the owner-rep's identity. Lenders see a separate visitor group with just the milestone-completion documentation they need for tranched draw approvals. Procore handles your daily RFIs and submittals during execution; Peony handles external owner and lender review where you need watermarks, audit trails, and the closeout package. Use both — they're complementary.

I'm a senior associate at a 30-attorney construction litigation practice — we have 35GB of as-built Revit, BIM clash reports, and CAD shop drawings as evidence in a project-defect case. Should we use a data room or eDiscovery?

For your 30-attorney practice's construction-defect case, the answer is both. eDiscovery (Relativity, Everlaw) is built for early-stage review — collection, processing, privilege coding, and TAR/CAL review across the full document corpus. A BIM-capable data room like Peony Business at $40/admin/month is built for late-stage distribution — share curated BIM and CAD subsets with expert witnesses, opposing counsel, mediators, and clients with watermarks and audit trails. Upload 35GB of as-built Revit federations, Navisworks clash reports, and shop drawings; configure visitor groups so each expert sees only the subset relevant to their opinion. Watermarks burn the expert's identity into every drawing view; screenshot protection blocks captures of confidential as-builts. Audit trails log every view with timestamps — exportable for sanctions motions or work-product disputes. eDiscovery tools are not designed for external BIM distribution.

We're a developer evaluating a $250M acquisition of a half-built mixed-use project — the seller's data room must include current BIM federations, change orders, and contractor agreements. What should I require?

For your $250M half-built mixed-use acquisition, require five things in the seller's data room beyond just file support. (1) NDA gates that gate every folder before access — most cloud storage tools have none. (2) Dynamic watermarks tied to viewer identity on every Revit view, schedule, and rendered image — static watermarks don't trace specific viewers. (3) Visitor-group permissions so different bidders see different subsets and consultants can't see other bidders' Q&A. (4) Page-level analytics showing dwell time per drawing — useful for identifying which subsystem the seller's team is hiding versus showcasing. (5) Audit trails on every view, exportable for change-of-control sign-offs and post-close disputes. Peony Business at $40/admin/month delivers all five; legacy VDRs charge per-page on raw BIM data and tier upgrades on storage.

I'm a CFO at a 60-person geotechnical engineering firm — we deliver BIM coordination plus subsurface analysis (sometimes Leapfrog .lfview models) to infrastructure clients. How does Peony handle this mix?

For your 60-person geotechnical engineering firm, Peony Business at $40/admin/month handles the full mix — BIM coordination (Revit federations, Navisworks NWD/NWF, IFC exports) alongside subsurface analysis files (Leapfrog .lfview/.lfproj geological models, well logs, borehole data, drilling videos). For BIM-heavy projects, see the full BIM workflow on this page. For projects dominated by geological/subsurface work, see our /use-cases/geological-data-room page covering Leapfrog, Vulcan, Surpac, and seismic distribution. NDA gates, dynamic watermarks, screenshot protection, and full audit trails apply to both file types. Your 5-admin firm pays $2,400/year flat across all infrastructure clients — versus the per-project Datasite or Procore licensing that geotech firms typically split between BIM and geological tools.

Federated. Watermarked. NDA-gated.

Set up your BIM data room in under 5 minutes. NDA gates, dynamic watermarks, and screenshot protection on Peony Business at $40/admin/month.
