Ontario is investing ~$190 billion in public infrastructure over the coming decade—spanning hospitals, schools, highways, and transit GHD. As mechanical contractors, that means planning for systems that must deliver reliability and maintainability over 30+ years—not just pass inspection today. In this blog, we explore why lifecycle focus matters and how forward-looking mechanical trades add real value.
1. Why Infrastructure Requires Long-Term Mechanical Planning
When it comes to Ontario infrastructure, the mechanical trades play a unique role: systems they install must serve multiple generations. Unlike private projects where upgrades may occur every 10–15 years, hospitals, schools, and transit hubs often rely on their original mechanical systems for 30 years or more. Poor upfront planning leads to costly replacements that strain public budgets and disrupt essential services.
Several factors make lifecycle planning critical:
Extended Lifecycles
Public infrastructure projects are designed to last decades. Every replacement cycle comes directly from taxpayer dollars, so mechanical systems must be engineered to maximize lifespan and minimize disruption.Complex Procurement Models
Projects such as the Lakeridge and Trillium hospitals illustrate the risks of accelerated builds and public–private partnership (P3) delivery models. The Auditor General of Ontario has flagged quality assurance shortfalls, rushed regulatory handovers, and costly change orders in these environments. Mechanical planning suffers most when schedules are compressed.Special-Use Environments
Hospitals, labs, and long-term care facilities require specialized systems—negative and positive pressure control, strict air change rates, and built-in redundancy. Without forward-looking design, these facilities face compliance issues and potential risks to patient safety.
The bottom line: mechanical trades infrastructure isn’t just about installing equipment; it’s about designing systems that can withstand three decades of use while supporting critical community needs.
2. Mechanical Failure is Costly
When mechanical systems underperform or fail, the financial impact on public infrastructure is immediate and significant. Unlike cosmetic deficiencies, mechanical failures often trigger cascading effects—higher operating costs, emergency repairs, and premature replacements that undermine the original project budget.
Auditor General Findings
A recent review of Ontario’s long-term care homes under the accelerated build pilot revealed costs nearly 50% higher per bed compared to typical projects (from $287,000 to approximately $493,000 per bed). Much of this increase stemmed from procurement miscalculations, rushed schedules, and inadequate coordination of mechanical systems (Auditor General of Ontario).Lifecycle Cost Amplification
In mechanical trades infrastructure, a dollar saved upfront can become ten dollars lost in lifecycle costs. Poor planning in HVAC, plumbing, or BAS systems leads to premature failures and extended downtime—disrupting hospitals, schools, and transit hubs where reliability is non-negotiable.Risk Beyond Budgets
Failures in ventilation, heating, or cooling are not just financial burdens—they also compromise public safety and service delivery. A hospital with an unreliable mechanical plant risks patient health. A transit hub with faulty systems risks service interruptions that ripple across entire communities.
The evidence is clear: long-term mechanical planning may involve higher upfront investment, but it consistently prevents the much greater financial and operational costs of failure.
3. Key Principles for 30-Year Mechanical Design
Designing mechanical systems for Ontario infrastructure projects requires more than code compliance. To last 30+ years, systems must be engineered with serviceability, redundancy, and preventative maintenance in mind. These principles define how the mechanical trades can ensure long-term performance.
a) Design for Serviceability
Future maintenance should be planned at the design stage. Mechanical rooms need adequate space for technicians to maneuver, with features such as catwalks, crane beams, and modular components that can be replaced without shutting down entire systems.
Documentation is just as important as layout. Tagged pipes, labelled panels, and as-built digital models create transparency, helping operators manage systems efficiently throughout their lifecycle. Serviceable design reduces downtime, lowers operating costs, and extends the lifespan of mechanical infrastructure.
b) Build in Redundancy
Public facilities like hospitals, schools, and transit hubs cannot afford outages. Mechanical systems must include backup capacity to ensure continuity. Dual-fuel boilers, standby pumps, and redundant control systems are standard in mission-critical environments where failure is not an option.
Redundancy increases upfront costs, but the payoff is reliability. When one system fails, another immediately takes over—protecting patients, students, and commuters who depend on uninterrupted service.
c) Stay Ahead on Maintenance
Mechanical performance is a moving target. By leveraging Building Automation Systems (BAS), operators can track pressures, vibrations, leaks, and energy drift in real time. Proactive alerts enable preventative maintenance before small issues become costly breakdowns.
Long-term planning also requires specifying parts and materials that will remain available for decades. Choosing durable components and vendors with legacy support prevents the scramble to replace obsolete equipment halfway through a system’s lifecycle.
The takeaway: mechanical infrastructure designed with serviceability, redundancy, and proactive maintenance can reliably meet the 30-year expectations of Ontario infrastructure projects.
4. A2 Mechanical Group’s Approach
At A2 Mechanical Group, we know that Ontario infrastructure projects demand more than short-term compliance. Our work is rooted in lifecycle thinking—ensuring mechanical systems perform reliably for decades, not just through warranty. This approach guides every stage of our involvement, from bidding to execution.
Lifecycle Reporting at the Bid Stage
Every institutional bid begins with a mechanical lifecycle report. This report outlines inspection intervals, anticipated component replacements, and likely points of failure over a 30-year horizon. By mapping these risks early, we set clear expectations for owners and reduce the chance of unforeseen costs later.Strategic Procurement Partnerships
Our procurement strategy prioritizes vendors with a proven track record of legacy parts and aftermarket support. By consolidating lead suppliers, we minimize the risk of parts obsolescence and ensure that replacement components remain available long into the future.Modular, Serviceable Installations
During execution, we design and install systems in a modular format. This allows individual components—whether pumps, chillers, or control panels—to be swapped cleanly without major disruption. Serviceability is built in from day one.
Through these steps, A2 Mechanical Group bridges the gap between design intent and long-term performance, giving owners and operators confidence that their facilities will meet the 30-year benchmark.

6. What’s Driving This Need Now?
The demand for long-term mechanical planning in Ontario infrastructure isn’t just theoretical—it’s being reinforced by audits, procurement shifts, and the realities of aging assets. Several forces are converging to make lifecycle thinking more urgent than ever.
Audit Findings and Funding Gaps
The Auditor General of Ontario has repeatedly flagged risks in accelerated builds and pilot programs, especially in the long-term care and healthcare sectors. Rushed procurement and compressed timelines often result in mechanical coordination issues, inflated costs, and systems that don’t meet lifecycle expectations.Procurement Model Revisions
Agencies such as Infrastructure Ontario and provincial ministries are reevaluating procurement models to prioritize long-term value rather than lowest upfront cost. This includes closer oversight of design-build-finance-maintain contracts and a stronger focus on quality assurance throughout the mechanical scope.Aging HVAC Fleets and Digital Gaps
Many of Ontario’s public facilities are operating with HVAC systems installed 20–30 years ago. These systems face energy inefficiencies, maintenance backlogs, and a lack of modern controls. Building codes and occupant expectations have evolved, leaving legacy systems unable to meet 21st-century standards without significant upgrades.Industry Insights and Professional Consensus
Engineering and construction firms, including groups like GHD, emphasize the need for sustainability, resilience, and digital integration in public infrastructure. The mechanical trades are central to delivering these outcomes, making lifecycle planning a priority for the next generation of projects.
Together, these drivers point to a simple truth: the future of mechanical trades infrastructure lies in building systems that are durable, adaptable, and ready for decades of reliable performance.
Building Systems That Last Generations
Truly modern mechanical contracting isn’t about the fastest installation or the lowest upfront bid. It’s about designing and delivering systems that will serve communities reliably for decades. For Ontario’s public infrastructure—hospitals, schools, transit hubs, and long-term care facilities—mechanical systems are the backbone of safety, comfort, and efficiency.
By focusing on lifecycle planning, redundancy, and proactive maintenance, the mechanical trades help reduce long-term costs, extend asset life, and prevent the cascading risks of failure. This approach builds not only better buildings but also stronger public trust in how infrastructure dollars are spent.
