Infrastructure Readiness as a Determinant of Healthcare Capital Success
Healthcare facility expansion is frequently driven by service line growth, population demand, and modernization initiatives. However, insufficient evaluation of underlying infrastructure systems before expansion introduces operational, financial, and strategic risk. Aging electrical, mechanical, plumbing, medical gas, and vertical transportation systems may lack capacity or redundancy to support new clinical loads.
Research from the American Society for Health Care Engineering, the American Hospital Association, and the U.S. Department of Energy indicates that deferred maintenance and aging facility systems contribute significantly to unplanned capital expenditures, energy inefficiency, and operational vulnerability.
This series examines the consequences of infrastructure misalignment and proposes a proactive assessment framework to support resilient healthcare growth.
As leaders in healthcare architecture, ARCHSOL has supported every major healthcare system in Arizona through comprehensive facility assessments designed to guide strategic expansion and long-term operational resilience. Our work extends beyond traditional design services to include detailed evaluations of existing infrastructure systems, clinical space utilization, and campus-level capacity. By analyzing mechanical, electrical, plumbing, and structural systems alongside evolving care delivery models, we help healthcare organizations understand how current facilities can support future growth.
Through these assessments, ARCHSOL provides healthcare leaders with clear insight into infrastructure readiness, system constraints, and opportunities for phased development. This approach enables hospital systems to align capital investments with clinical priorities while reducing the operational risks that can emerge when expansion occurs without a full understanding of underlying facility capacity. The result is a strategic roadmap that supports safe, efficient, and sustainable healthcare environments for the communities they serve.
The National Context: Aging Healthcare Infrastructure
The average age of U.S. hospital facilities exceeds 11 years, with many acute care campuses operating in buildings constructed several decades ago (American Hospital Association, 2023). The American Society for Health Care Engineering estimates that deferred maintenance costs in healthcare facilities nationally exceed hundreds of billions of dollars, reflecting accumulated infrastructure degradation and underinvestment (ASHE, 2022).
Simultaneously, healthcare delivery has become increasingly technology-intensive. Advanced imaging, robotic surgery platforms, expanded data systems, and infection control requirements place a higher demand on:
- Electrical distribution systems
- Emergency power capacity
- HVAC and chilled water systems
- Medical gas infrastructure
- IT and low-voltage networks
When expansion projects are layered onto aging infrastructure without comprehensive system validation, risk exposure increases across clinical, operational, regulatory, and financial dimensions.
| AZ Facility Type | Avg Opening Year | Avg Age (2026) |
| Short Term Acute | 1958 | 68 years |
| Critical Access | 1965 | 61 years |
| Psychiatric | 1988 | 38 years |
| Rehabilitation | 2005 | 21 years |
| Long Term Acute | 2000 | 26 years |
| System | Proxy Avg Opening Year | Proxy Avg Age 2026 |
| Banner Health | 1972 | 54 years |
| Dignity Health AZ | 1969 | 57 years |
| HonorHealth | 1977 | 49 years |
| Abrazo Health | 1984 | 42 years |
| Mayo Clinic AZ | 1987 | 39 years |
In many Arizona systems, the institutional age of major campuses exceeds 50 years. While patient towers may have been renovated or replaced, the backbone infrastructure often remains partially legacy. Central plants, chilled water distribution, medical gas mains, electrical switchgear, emergency power systems, and underground utilities frequently span multiple construction eras. Documentation is incomplete. Capacity assumptions are often based on historical loads rather than measured performance.
When expansion proceeds without validating these systems under current demand conditions, several risks emerge.
| Risk Category | Risk Description | Likelihood on Aging Campuses | Impact Severity | Operational Consequence | Mitigation Strategy |
| Capacity Overload | Existing electrical, chilled water, medical gas, or steam systems exceed redundancy thresholds under added load | High | High | System failure, shutdown risk, emergency capital spend | Pre-design capacity study, real-time load monitoring, central plant modeling |
| Deferred Maintenance Escalation | Expansion stresses equipment beyond useful life | High | High | Equipment failure during construction or early occupancy | Asset condition assessment, lifecycle modeling, integrate replacement into capital plan |
| Underground Utility Unknowns | Inaccurate or incomplete as built documentation | High | Medium to High | Change orders, schedule delay, safety risk | Ground penetrating radar, potholing, early site validation |
| Life Safety Non-Compliance | Phasing reveals legacy fire or egress deficiencies | Medium | High | Permit delays, accreditation exposure | Full life safety audit prior to design finalization |
| Infection Control Risk | Legacy HVAC and pressure relationships insufficient for expansion adjacency | Medium | High | ICRA failure, survey findings, patient risk | HVAC validation study, pressure testing, airflow balancing |
| Structural Capacity Limits | Existing framing not verified for vertical or equipment loads | Medium | High | Reinforcement costs, redesign | Structural load analysis, selective destructive investigation |
| Phasing Disruption | Temporary utility tie-ins impact ongoing operations | High | High | OR downtime, imaging disruption, revenue loss | Phasing simulation, redundancy staging, night or off peak tie ins |
| Regulatory Trigger Events | Expansion triggers a full code upgrade of adjacent areas | Medium | High | Increased scope and cost | Early AHJ engagement, code pathway strategy memo |
| Data Infrastructure Gaps | Legacy IT backbone insufficient for new smart systems | Medium | Medium | Clinical workflow inefficiency | IT backbone audit, network capacity validation |
| Financial Pro Forma Drift | Mid-construction infrastructure discovery changes budget | High | High | Capital committee re approval, board escalation | Early risk contingency modeling, transparent risk register |
Healthcare expansion succeeds when clinical vision is supported by infrastructure readiness. Before new space is planned, health systems must understand the true capacity, resilience, and condition of the systems that sustain operations. ARCHSOL approaches expansion planning through a comprehensive infrastructure readiness framework that evaluates electrical distribution, central plant performance, life safety systems, medical gas networks, structural capacity, and digital infrastructure before design decisions are finalized. By integrating facility condition assessment, infrastructure modeling, and phasing strategy early in the planning process, organizations can reduce capital risk, avoid mid construction discoveries, and align expansion investments with long term operational stability. For healthcare leaders planning future growth, infrastructure validation is not simply a technical exercise. It is a strategic step that ensures expansion strengthens the health system rather than exposing hidden vulnerabilities.
