Managing Strategic Risk in Long Term Infrastructure Projects

Thursday, 1 October 2026

Key takeaways

Infrastructure projects spanning five to thirty years face risks that cannot be eliminated at the planning stage. They must be governed throughout the project lifecycle
Strategic risks in infrastructure include political and policy change, cost escalation beyond contingency, demand forecasting error, supply chain disruption and regulatory change
Australian Commonwealth and state government infrastructure appraisal frameworks require risk assessment as a core element of the business case, but many projects underinvest in ongoing risk governance after approval
The projects that manage strategic risk most effectively are those that maintain active risk registers with executive level oversight, not those with the most detailed initial risk assessment
Risk management capability for infrastructure leaders requires both the technical skills to assess risk and the governance skills to escalate and communicate risk to decision makers

Strategic risk in infrastructure is the exposure to events or conditions that could fundamentally change whether a project achieves its intended outcome. These are not operational risks like weather delays or material shortages. They are the risks that alter the project’s viability: a change of government policy that removes the project’s mandate, a cost escalation that exceeds the approved budget by a factor that contingency cannot absorb, a demographic shift that undermines the demand assumptions the business case relied on or a regulatory change that requires the project to be redesigned after construction has commenced. The ANAO’s audit of cyber security readiness for the 2026 Census illustrates how strategic risks, including cyber risks, require active monitoring by oversight committees rather than one time assessment.

What types of strategic risk affect infrastructure projects?

Five categories of strategic risk recur across major infrastructure programs. Political and policy risk is the first. A project approved under one government may lose its mandate under the next. In the Federal context, the Department of Finance’s Commonwealth Investment Framework acknowledges this by requiring investment proposals to align with the government’s strategic objectives, but strategic objectives change with electoral cycles.

Cost escalation risk is the second. Long term projects face cumulative cost pressures from input price movements, scope changes, design revisions and supply chain disruption. The Infrastructure Australia assessment framework requires cost benefit analysis with sensitivity testing, but sensitivity testing at the business case stage cannot predict every cost escalation that will emerge over a twenty year construction program.

Demand risk is the third: the possibility that the population growth, traffic volumes or service demand that justified the investment do not materialise as forecast. Regulatory risk is the fourth: changes in environmental, safety or planning legislation that require design modifications after construction has commenced. Supply chain risk is the fifth: the concentration of critical materials or specialist contractors in markets that are vulnerable to geopolitical disruption or capacity constraints.

Why do projects underinvest in ongoing risk governance?

Most infrastructure risk management effort is concentrated at the business case stage. The risk assessment is thorough, the risk register is populated, the sensitivity analysis is rigorous. Then the project is approved. Once construction begins, the attention shifts to delivery: schedules, milestones, contract management and cost tracking. The risk register becomes a compliance document that is updated periodically rather than a governance tool that drives decisions.

The consequence is that strategic risks that emerge after approval are not identified, escalated or governed with the same discipline as operational delivery risks. A project steering committee that receives detailed reports on construction progress but superficial reports on strategic risk exposure is governing the wrong end of the problem.

How should infrastructure leaders govern strategic risk?

Active risk governance requires three practices. The first is a dedicated strategic risk register that is separate from the operational risk register and reviewed at executive or board level rather than at project team level. The second is trigger based escalation: defining in advance the conditions under which a strategic risk must be escalated to the sponsoring minister, the expenditure review committee or the cabinet. The third is periodic reassessment of the business case assumptions, comparing the demand forecasts, cost estimates and benefit projections from the original business case against current evidence.

The APMG Five Case Model describes business case development as an iterative process. The same principle applies to risk governance: the risk assessment that was adequate at the strategic outline case may be insufficient by the time the project reaches full business case, and wholly inadequate five years into construction.

How can professionals build this capability?

AcademyGlobal (AG), the Chartered Institute of Procurement & Supply (CIPS) Centre of Excellence for Australia, New Zealand and Southeast Asia, delivers programs that build strategic risk management capability. AG’s Strategic Risk Management courses address how to identify, assess and govern strategic risks in complex organisational environments. For professionals seeking foundational risk management skills, AG’s Risk Management Fundamentals provides the structured framework for risk identification, assessment and treatment.

The infrastructure projects that deliver on their promise are not the ones that eliminate risk at the planning stage. They are the ones that govern risk actively throughout the lifecycle.

Frequently asked questions

What is strategic risk in infrastructure?
Strategic risk is exposure to events that could fundamentally change whether a project achieves its intended outcome: policy change, cost escalation beyond contingency, demand forecasting error, regulatory change or supply chain disruption.
Why is risk governance often weaker after project approval?
Attention shifts to delivery: schedules, milestones and cost tracking. The risk register becomes a compliance document rather than a governance tool. Strategic risks that emerge after approval are not escalated with the same discipline.
How should strategic risk be governed differently from operational risk?
Through a separate strategic risk register reviewed at executive level, trigger based escalation criteria and periodic reassessment of business case assumptions against current evidence.
Does the business case risk assessment remain valid throughout the project?
No. Business case assumptions about demand, cost and regulatory settings change over time. Periodic reassessment is essential, especially for projects spanning five to thirty years.
Where can I build strategic risk management capability?
AcademyGlobal’s Strategic Risk Management courses address strategic risk identification, assessment and governance in complex environments.
