Five recurring causes, lessons from Victoria and a better standard for project delivery.
Municipal infrastructure is essential to public safety, economic growth and quality of life. When major projects cost far more or take much longer than first presented, residents pay through higher debt, interest, taxes, deferred maintenance and delayed public benefits.
Cost and schedule overruns are rarely caused by one surprise. They usually develop through a chain of early decisions: immature design, expanding scope, delayed approvals, poorly allocated risk and unclear accountability.
Summary
Cost overruns do not always prove incompetence; infrastructure projects contain genuine uncertainty. However, many failures arise from foreseeable management problems: committing too early, expanding scope without trade-offs, delaying decisions, mismatching procurement to risk and failing to establish clear accountability.
Residents should not have to wait until a project is complete to learn that its budget or schedule has failed. They deserve realistic estimates, transparent choices, visible performance and early corrective action.
What Residents Should Be Able to See
- The approved budget and current forecast at completion.
- The approved completion date and current forecast opening date.
- Contingency committed, spent and remaining.
- Major risks, trends and responsible mitigation owners.
- Change orders, their causes and decisions required from Council.
- The accountable executive responsible for delivery.
The Five Recurring Causes
- Premature commitments – firm budgets and completion dates are announced before design and investigations are sufficiently complete.
- Scope growth – individually reasonable additions accumulate without a transparent reset of cost, schedule and operating implications.
- Decision delay – repeated reconsideration exposes projects to inflation, remobilization, changing codes and continued maintenance of aging assets.
- Weak risk and procurement strategy – contracts, contingencies, supply chains and quality controls do not match project complexity.
- Unclear governance – responsibility is fragmented and public reporting focuses on past spending instead of the forecast at completion.
Lessons From Victoria
Johnson Street Bridge
- A replacement first discussed at approximately $40 million ultimately cost more than $105 million.
- The expected September 2015 opening moved to March 2018.
- Key problems included incomplete design, contractual disputes, overseas steel defects, rework, low early contingency and uncertainty over responsibility.
- The lesson: do not procure a complex, one-of-a-kind asset until design, risk allocation, inspection and quality assurance are sufficiently mature.
Crystal Pool Replacement
- Council approved a $69.4-million replacement budget in 2017; in 2025, voters authorized borrowing of up to $168.9 million for the current, broader project.
- The figures are not directly comparable because scope, financing, price year, codes and project requirements changed.
- The history illustrates how prolonged decisions expose taxpayers to inflation, escalation, redesign and continued maintenance costs.
- Important qualification: as of August 2026, the City reported the active project within its approved scope and budget, with minor schedule challenges.
- Concept estimates should not be presented as construction ready prices.
- Complete geotechnical, utility, environmental, hazardous material and site investigations before fixing the construction budget.
- Disclose estimate ranges and design maturity rather than offering false precision.
- Require independent cost, schedule, risk and constructability reviews before construction authorization.
- Extra rooms, finishes, sustainability features, parking, technology and stakeholder requests can each add design, construction and operating costs.
- Every material change should disclose its purpose, capital and lifecycle cost, schedule effect, risks and funding source.
- If the total budget must remain fixed, identify what will be reduced, deferred or removed.
- Delay increases labour and material costs while studies, estimates and designs become outdated.
- Aging facilities continue to require maintenance and emergency repair while public benefits are postponed.
- Council should set decision dates and reopen settled questions only when materially new evidence appears.
- Allocate each risk to the party best able to understand, price and control it.
- Evaluate relevant experience, quality systems, financial capacity, suppliers, staffing and recovery options, not only the lowest initial bid.
- Set contingency from identified risks and report how much is committed, spent and remaining.
- Strengthen oversight of remote or specialized fabrication where inspection and correction are difficult.
- Assign one accountable executive, a qualified project director and an integrated delivery team.
- Define who controls scope, approves changes, accepts risk and certifies quality.
- Report the current forecast at completion, forecast opening date, contingency, risks, change orders and corrective action.
- Trigger an independent recovery review when cost, schedule or contingency thresholds are exceeded.
Ten Practical Reforms
- Use formal stage-gate approvals from concept through design, procurement, construction and commissioning.
- Show estimate ranges and confidence levels until design is mature enough for a reliable construction budget.
- Require independent cost, schedule, constructability and risk reviews for major projects.
- Establish a clear baseline scope and transparent approval for every material change.
- Compare forecasts with the actual performance of similar completed projects.
- Choose procurement models based on project risk and complexity, not habit or the lowest apparent price.
- Maintain risk-based contingency and prevent it from becoming an informal source of added scope.
- Assign one accountable executive and publish a clear governance structure.
- Publish a standardized quarterly dashboard focused on forecast cost, schedule, risk and corrective action.
- Complete post-project reviews and publish lessons so mistakes are not repeated.
