Overview

Healthcare Structural Engineering

Healthcare facilities are not standard commercial buildings. The codes are stricter, the review process is longer, the mechanical systems are heavier, and the consequences of getting it wrong are measured in patient safety, not just dollars.

We provide structural engineering for hospitals, urgent care clinics, surgical centers, imaging facilities, pharmaceutical labs, and medical office buildings. Our work accounts for the unique loading conditions healthcare buildings present: heavy MRI equipment with strict vibration limits, radiation shielding walls that weigh three times what normal partitions weigh, elevated floor live loads for patient transport corridors, and rooftop mechanical systems that seem to multiply with every renovation.

Beyond the structural design itself, healthcare projects require navigation through regulatory review processes that commercial projects never see. Depending on the state, your drawings may need review by OSHPD, HFAP, The Joint Commission, or a state health department plan review office, each with their own submission requirements, timelines, and comment cycles.

Facility Types

Hospitals, Clinics & Specialized Facilities

Every healthcare facility type carries its own structural demands. A freestanding emergency department has different seismic performance requirements than a medical office building. A pharmaceutical cleanroom needs vibration criteria that a general clinic doesn't. We tailor the structural approach to match the specific facility classification and its intended use.

Specialized Design

Heavy Equipment & Shielding Engineering

Some of the most demanding structural work in healthcare happens in rooms that most people will never think about. An MRI suite, for example, requires a foundation that isolates the magnet from building vibration, a structural slab that can support equipment weighing 15,000 to 25,000 pounds, and coordination with the RF shielding enclosure that must remain continuous and uninterrupted.

Radiation therapy vaults present a different challenge entirely. Concrete shielding walls can be 4 to 8 feet thick, creating concentrated loads that often require independent foundation systems. The maze entrance geometry, designed to prevent radiation scatter, creates asymmetric loading conditions that need careful attention to lateral stability.

We coordinate closely with equipment vendors, radiation physicists, and MEP engineers to ensure the structural design supports every system in the room without conflicts. When equipment gets replaced with a heavier model five years later, we handle the re-analysis and structural modifications.

Code Compliance

Healthcare Code Requirements

Why healthcare structural engineering is fundamentally different from standard commercial work.

Risk Category IV Classification

Hospitals with emergency departments and surgical facilities are classified as Risk Category IV under ASCE 7. This means an Importance Factor of 1.5 for seismic design. The structure must be designed to remain operational after a design-level earthquake, not just prevent collapse.

FGI Guidelines Compliance

The Facility Guidelines Institute (FGI) publishes design and construction requirements adopted by most states. These go beyond IBC and address everything from minimum floor-to-floor heights that affect structural depth, to vibration criteria for imaging rooms, to specific corridor width requirements that constrain column placement.

State Agency Plan Review

In many states, healthcare projects bypass local building departments entirely. California's OSHPD (now HCAI), Texas HHSC, and similar agencies conduct their own plan review with stricter standards and longer review cycles. Submission packages must be thorough. Incomplete applications restart the clock.

Elevated Floor Live Loads

Standard office floors are designed for 50 psf live load. Hospital patient rooms require 40 psf minimum, but corridors serving patient areas jump to 80 psf. Operating rooms, mechanical spaces, and storage areas can require 100 to 150 psf. These variations create complex framing transitions within a single floor plate.

Vibration Criteria for Imaging

MRI and CT equipment manufacturers publish strict vibration criteria, often VC-C or VC-D on the vibration criterion curve. This means the structural floor system must limit velocity amplitudes to 4,000 or 2,000 micro-inches per second. Meeting this on upper floors of a multi-story building requires careful bay spacing, deeper beams, and sometimes isolated structural systems.

Progressive Collapse Resistance

Large healthcare facilities may trigger progressive collapse design requirements, particularly those tied to government funding or VA projects. The structure must demonstrate the ability to bridge over a removed column without disproportionate collapse, requiring redundant load paths and enhanced connection detailing.
