Complex healthcare facilities demand more than successful construction, they require systems that can be safely accessed, inspected, and maintained for decades. On a recently completed 1.8‑million‑square‑foot university medical center, EEI Building Performance supported early, multidisciplinary BIM collaboration to help ensure long‑term access and maintainability across critical life‑safety and environmental systems.
The Challenge
During commissioning of an adjacent cancer hospital, the EEI project team uncovered a recurring issue:
- Fire and smoke dampers were difficult, to access for inspection and maintenance
- Systems had been designed and installed for constructability, with less focus on long‑term serviceability
- Limited access created ongoing operational and compliance risk
This experience led the client to require enhanced BIM coordination early in design, with participation from:
- EEI Building Performance (Commissioning Authority)
- Engineer of Record
- CMAR team
- Trade partners
The BIM‑Driven Approach
Rather than relying solely on clash detection reports, the team adopted a shared principle: diverse expertise leads to better outcomes. Key strategies included:
- Weekly, multi‑party BIM review sessions
- A dedicated BIM Manager facilitating real‑world service scenario discussions
- Custom model views focused on access, clearance, and replacement paths
Measurable Outcomes
Early and sustained BIM collaboration delivered tangible improvements, including:
- Standardized VAV access in patient areas for consistent maintenance clearances
- Coordinated prefabricated toilet rooms with accessible cleanouts
- Verified lift access and motor replacement paths for high‑bay exhaust fans
- Modeled pandemic‑mode damper motors to eliminate the need for scaffolding
- Resolved HEPA filter replacement conflicts and chilled‑water piping access issues
Key Takeaway
Access requirements must be clearly defined, reviewed, and enforced. When field installation deviated from the coordinated model, reduced access required corrective work reinforcing the importance of verification throughout construction. For owners delivering complex healthcare facilities, early, inclusive BIM collaboration supported by commissioning expertise, remains one of the most effective tools for creating safer, more maintainable, and more resilient buildings.
