G2Infrastructure Deal Requirements
These are not ordinary M&A processes. A single PPP tender can involve three rival consortiums, each with 15-30 advisers, competing over 12-24 months under strict procurement rules. Your VDR must handle this from day one.
- Sealed workspaces so rival bid groups never see each other
- Q&A workflows that scale to 1,000+ questions per process
- Native handling of drawings, CAD files, and GIS data
- Audit trails that survive a procurement challenge
Why VDR Choice Matters for Project Finance
Financial close depends on lender confidence. Lenders' technical, legal, and insurance advisers all work from the same room. A well-structured data room with clean disclosure staging can shave weeks off the path to financial close and reduce the risk of a bid protest derailing the entire procurement.
Infrastructure & Project Finance VDR Requirements
Infrastructure transactions, whether a greenfield PPP tender, a brownfield asset sale, or a refinancing, put demands on a data room that ordinary corporate M&A never does. Five requirements separate a workable platform from one that fails mid-process.
Consortium Bidding with Sealed Bid Groups
In a competitive tender, two or three consortiums bid against each other, and each consortium is itself a coalition: an equity sponsor, a construction contractor, an operator, lenders, and advisers. The data room must keep rival bid groups completely invisible to each other:
- Workspace isolation: Bidder A must never see Bidder B's users, questions, or activity, not even in a user directory or notification email
- Segregated Q&A: Questions and answers visible only to the asking consortium, with the option to broadcast anonymized answers to all bidders
- Conflict management: The same law firm or technical adviser sometimes appears on two consortiums behind ethical walls; permissions must handle that without leakage
Massive Q&A Volumes Across Adviser Workstreams
A mid-sized project finance process routinely generates 500-1,500 questions from lenders' technical advisers, legal counsel, insurance advisers, and model auditors. Without structured routing, deadlines slip and duplicate answers create disclosure risk. Look for topic-based routing, subject matter expert assignment, approval chains before answers publish, and full Q&A export for the disclosure record.
Drawing and CAD File Handling
Technical due diligence lives in drawings: general arrangement drawings, P&IDs, geotechnical surveys, as-builts. These arrive as DWG, DXF, and large-format PDF files that can run 200MB+ each. The VDR needs in-browser viewing for large-format documents, no forced conversion that destroys layer data, and bulk upload that does not choke on a 40GB drawing package.
Multi-Year Room Lifespans
A corporate M&A room lives 4-6 months. An infrastructure room opens at tender launch, runs through preferred bidder selection and financial close, and often stays live for construction-phase reporting and future refinancing. Plan for a 2-5 year lifespan, with pricing and archiving terms that reflect it. Per-page pricing models become ruinous at this duration; negotiate flat annual terms.
Government Procurement Compliance
When the counterparty is a ministry, municipality, or state-owned entity, the data room becomes part of the procurement record. Equal treatment of bidders must be demonstrable: identical document access timestamps, logged disclosure of every addendum, and audit reports a procurement authority can file. A losing bidder's challenge will subpoena exactly this evidence.

Standard Project Finance Data Room Structure
Lenders' advisers expect a recognizable index. Here's the structure used on most project finance and infrastructure processes:
Project & Contractual
- 1. Concession / PPA: Concession agreement, power purchase agreement, offtake contracts, direct agreements
- 2. Permits & Consents: Planning permissions, environmental approvals, grid connection, regulatory licenses
- 3. Land & Rights of Way: Title documents, easements, wayleaves, expropriation records, surveys
- 4. EPC & O&M: Construction contract, performance guarantees, operations and maintenance agreements, interface agreements
Financial & Diligence
- 5. Financial Model: Base case model, assumptions book, sensitivities, model audit reports
- 6. Insurance: Construction all-risks, delay in start-up, operational policies, insurance adviser reports
- 7. Lender DD Reports: Technical, legal, insurance, market, and environmental due diligence reports
- 8. ESG & Environmental: ESIA studies, Equator Principles compliance, stakeholder engagement, biodiversity plans
Structuring Tip
Mirror the index to the conditions precedent schedule in the facility agreement. When lenders' counsel checks CPs at financial close, every document should be findable by its CP reference number. This alone can save a week at close.
Security & Procurement Compliance
Infrastructure processes carry two compliance burdens most deals never face: procurement fairness obligations and government data residency rules.
Procurement Fairness
- Simultaneous document release to all bidders
- Logged addendum acknowledgments
- Anonymized Q&A broadcasts
- Exportable equal-treatment evidence
Data Residency
- In-country hosting for government counterparties
- EU data centers for EU-funded projects
- Critical infrastructure data restrictions
- Cross-border transfer controls
Security Baseline
- SOC 2 Type II and ISO 27001
- AES-256 encryption
- Multi-factor authentication
- Dynamic watermarking on drawings
Compare Infrastructure-Grade VDR Providers
Provider fit depends on the scale of the process and who sits on the other side of the table:
Large PPP Tenders & Core Infrastructure M&A
Intralinks and Datasite are the default on billion-dollar concessions and airport, port, and toll road processes. Both handle sealed multi-consortium structures, thousand-question Q&A volumes, and the multi-year lifespans government procurements demand. Expect premium pricing and negotiate flat annual terms.
Fund-Level Infrastructure & Energy Transition Deals
iDeals and Ansarada hit the sweet spot for infrastructure secondaries, renewables portfolios, and battery storage or hydrogen platform deals. Strong Q&A tooling and materially lower cost than the bulge-bracket platforms, with Ansarada particularly established in Australian and UK infrastructure processes.

Frequently Asked Questions
How do tender data rooms keep rival consortiums separated?
+
Enterprise VDRs create sealed workspaces per consortium: each bid group sees only its own users, documents, and Q&A thread. The seller or procurement authority sees everything; bidders see nothing of each other, including in user directories and email notifications. Test this before launch by logging in as a dummy user in each workspace, because a single misconfigured group can compromise the entire procurement.
How long does a project finance data room typically stay open?
+
Far longer than a standard M&A room. A tender room opens at RFQ or EOI stage and runs through preferred bidder selection, lender due diligence, and financial close, commonly 18-36 months total. Many sponsors then keep the room live as a construction-phase document repository and reopen it for refinancing 5-7 years later. Negotiate multi-year flat pricing upfront; per-page or per-month models get expensive fast at this duration.
How do you handle thousands of Q&A questions in one process?
+
Use topic-based routing: tag every question by workstream (legal, technical, insurance, financial model, environmental) and auto-route to a named subject matter expert with a response deadline. Add an approval step so counsel signs off before answers publish, and run weekly duplicate sweeps so the same question is not answered twice with different wording. Export the full Q&A log at close, since it forms part of the disclosure record.
Can data rooms handle CAD files and large-format drawings?
+
The infrastructure-grade platforms handle DWG, DXF, and large-format PDF viewing in the browser without forcing downloads. Check three things: per-file size limits (drawing sets routinely exceed 200MB), whether the viewer preserves zoom quality on E-size drawings, and whether watermarking works on drawing formats. If the platform converts CAD to flattened images, layer data is lost and technical advisers will demand native downloads instead.
What access do lenders' technical advisers need?
+
Lenders' technical advisers (the LTA or independent engineer) need the full technical folder: EPC contract and schedules, drawings, geotechnical and site surveys, permits, grid connection agreements, and the O&M contract. They usually also need the financial model's technical assumptions. Give them a dedicated user group with read access to those sections, Q&A rights routed to the sponsor's technical lead, and no access to competing bidder information or commercially sensitive pricing outside their scope.
