Conducting Infrastructure Due Diligence

When To Use

• Evaluating an infrastructure asset (toll road, airport, port, power plant, water/wastewater system, broadband network) for acquisition, concession bid, or refinancing
• Assessing condition and remaining useful life of physical assets before capital commitment
• Reviewing regulatory and permitting frameworks for greenfield or brownfield projects
• Conducting pre-close DD for PPP/P3 transactions or infrastructure fund investments
• Evaluating environmental liabilities, community impact, or social license risks tied to an asset

Inputs To Gather

• Asset description: asset type, location, age, original construction specs, and current operator
• Financial model / base case: projected revenues, O&M budgets, capex reserves, and debt service coverage
• Concession or contract documents: concession agreement, offtake/PPA, EPC/O&M contracts, government support agreements
• Technical reports: independent engineer (IE) reports, condition assessments, traffic/demand studies
• Regulatory filings: permits, licenses, tariff orders, rate-case history, environmental compliance records
• Insurance program: current policies, loss history, and pending claims
• Environmental / social data: Phase I/II ESA reports, EIS/EIA, community engagement records, land acquisition status
• Title and real property: ownership chain, easements, rights-of-way, encroachments

Workflow

1. Scope & Organize the DD Workstreams

Define workstreams aligned to key risk categories:

• Technical / Engineering: physical condition, design adequacy, deferred maintenance backlog, remaining useful life, seismic/climate resilience
• Regulatory & Permitting: current permits and expiration dates, pending proceedings, tariff/rate-setting mechanism, political/sovereign risk [VERIFY jurisdiction-specific regulatory bodies and approval timelines]
• Environmental & Social: contamination history, remediation obligations, emissions compliance, community opposition, resettlement or land acquisition disputes
• Legal & Contractual: concession terms (duration, handback conditions, termination triggers), EPC/O&M contractor performance, step-in rights, lender consent requirements
• Financial & Commercial: demand/traffic risk, revenue model sensitivity, counterparty creditworthiness, capex waterfall adequacy

Assign each workstream an owner, timeline, and materiality threshold for flagging findings.

2. Technical Asset Assessment

• Review IE report for asset condition ratings; cross-check against O&M logs and capital expenditure history
• Identify deferred maintenance items and estimate cost-to-cure vs. remaining concession or hold period
• Assess lifecycle capex needs — compare sponsor's base case assumptions against IE recommendations
• Evaluate technology obsolescence risk (e.g., toll collection systems, generation equipment, signaling)
• Check climate/natural hazard exposure: flood zones, seismic classification, wildfire risk, sea-level rise projections [VERIFY local climate adaptation requirements]

3. Regulatory & Permitting Review

• Map all required permits and licenses; confirm current status and renewal timelines
• Identify pending or anticipated regulatory proceedings that could affect tariffs, rates, or operating authority
• For PPP assets: review government payment mechanisms, availability payment formulas, and termination compensation clauses [VERIFY sovereign immunity and dispute resolution forum]
• Assess political risk — changes in government policy, re-nationalization precedent, local content requirements
• Confirm compliance with sector-specific regulations (e.g., FERC for US energy, OSHA for construction safety, FAA for airports) [VERIFY applicable regulatory regime by jurisdiction]

4. Environmental & Community Impact

• Review Phase I/II ESA findings; quantify known or potential remediation liabilities
• Check emissions permits, discharge limits, and compliance history against current regulations
• Evaluate community and stakeholder sentiment — review public comment records, media coverage, pending litigation
• For greenfield: confirm EIA/EIS approval status, land acquisition completion percentage, and resettlement plan adequacy
• Assess ESG alignment with investor mandates (GRESB score, TCFD disclosure readiness, IFC Performance Standards)

5. Contractual & Counterparty Analysis

• Abstract key terms from concession agreement: duration, handback conditions, performance benchmarks, force majeure, change-in-law protections
• Review EPC contract — liquidated damages adequacy, warranty periods, defects liability
• Evaluate O&M contract scope, KPIs, penalty/bonus mechanisms, and termination-for-convenience provisions
• Assess counterparty credit: offtaker/government creditworthiness, guarantor standing, political risk insurance coverage
• Confirm lender consent and intercreditor requirements for any change of control or refinancing

6. Synthesize Findings & Risk Matrix

• Compile workstream findings into a consolidated risk register with severity (high/medium/low) and likelihood ratings
• Quantify material risks in financial terms — impact on IRR, DSCR, and equity value
• Identify deal-breakers vs. mitigable risks vs. acceptable risks with pricing adjustments
• Prepare a DD summary memo suitable for investment committee presentation

Output

Produce a structured DD report containing:

• Executive summary with go/no-go recommendation and key risk flags
• Workstream reports (technical, regulatory, environmental, legal, financial) with detailed findings
• Risk matrix mapping each identified risk to severity, likelihood, mitigation strategy, and responsible party
• Condition precedent / closing checklist items flowing from DD findings (e.g., required consents, remediation escrows, insurance endorsements)
• Appendix of source documents reviewed, site visit notes, and expert interview summaries

Quality Checks

• Every material finding is traced to a source document or expert opinion — no unsupported conclusions
• Financial impacts are quantified where possible; qualitative risks include a clear rationale for severity rating
• All jurisdiction-dependent points (permit regimes, regulatory bodies, environmental standards) are marked [VERIFY]
• Concession/contract abstracts have been cross-checked against the actual executed documents, not summaries
• Handback and termination provisions are stress-tested against downside scenarios
• Report distinguishes between confirmed findings and areas requiring further investigation
• ESG/community risk section reflects current investor standards and is not treated as a checkbox exercise
