OSHPD Seismic Certification for Hospital Equipment: HCAI Pre-Approval Guide

Healthcare facilities in California operate under some of the most demanding seismic safety requirements in the United States. Hospitals, emergency centers, medical campuses, and other essential facilities must remain operational after major earthquakes, making the seismic qualification of nonstructural components and equipment a critical part of modern healthcare construction's seismic certification is one of the most recognized terms used by engineers, equipment manufacturers, contractors, and facility managers when referring to the seismic qualification process for healthcare equipment in California. Although the Office of Statewide Health Planning and Development (OSHPD) functions transitioned into the California Department of Health Care Access and Information (HCAI), the terminology remains widely used throughout the construction and engineering industries.

For healthcare projects, seismic certification is not limited to proving that equipment can withstand earthquake forces. It involves a complete engineering process that evaluates equipment performance, anchorage systems, support structures, installation conditions, and compliance documentation. The goal is to ensure that critical systems remain functional and safe when facilities are needed most.

Medical equipment manufacturers, structural engineers, MEP contractors, architects, and hospital administrators must understand how HCAI requirements interact with major engineering standards including ASCE 7-22, the California Building Code (CBC), International Building Code (IBC), ACI 318-19 Chapter 17, and ICC-ES AC156 shake table testing procedures.

A successful certification pathway requires more than equipment data sheets. It requires properly prepared seismic qualification documentation, engineering calculations, testing verification when required, and coordination between manufacturers and project teams.

Through technical engineering documentation and code-based analysis, projects can move through review processes with greater confidence and fewer compliance challenges.

What Is OSHPD Seismic Certification and Why Is It Required for Healthcare Equipment?

Understanding the Transition From OSHPD to HCAI

OSHPD seismic certification refers to the seismic qualification and approval processes historically associated with California healthcare facility construction. While OSHPD is no longer the active agency name for these responsibilities, many industry professionals continue using OSHPD terminology because it remains deeply established in healthcare construction specifications, manufacturer documentation, and engineering discussions.

Today, HCAI oversees healthcare facility planning, design review, and construction compliance throughout California. The agency maintains strict requirements to ensure hospitals and essential healthcare buildings achieve appropriate levels of seismic performance.

The transition from OSHPD to HCAI did not eliminate the need for seismic qualification. Instead, the regulatory framework continues to emphasize the importance of protecting nonstructural systems that directly affect hospital operations.

Unlike conventional commercial buildings, healthcare facilities contain numerous critical systems that must function after an earthquake event. These include imaging equipment, emergency power systems, medical gas systems, HVAC equipment, electrical distribution systems, and specialized patient-care technology.

A piece of equipment may be structurally strong, but its performance depends heavily on how it is connected to the building. Improper anchorage, insufficient restraint, or inadequate support design can result in equipment movement, failure, or operational downtime.

This is why OSHPD seismic certification requires consideration of the entire equipment system rather than only the equipment itself.

Role of HCAI in California Healthcare Construction

HCAI plays a central role in reviewing healthcare construction projects throughout California. Its oversight applies to hospitals, skilled nursing facilities, outpatient facilities, and other regulated healthcare environments.

Seismic compliance reviews typically evaluate whether equipment and building systems meet applicable structural and nonstructural design requirements. Engineers must demonstrate that equipment installations comply with governing codes and project requirements.

For nonstructural components, ASCE 7-22 Chapter 13 provides the primary framework for seismic design requirements. This chapter addresses components that are attached to buildings but are not part of the primary structural system.

Examples include:

HCAI-regulated projects often require detailed documentation showing that equipment has been appropriately qualified and anchored. Depending on the application, this may include manufacturer certification, shake table testing results, engineering calculations, and stamped drawings.

For equipment manufacturers entering the California healthcare market, understanding HCAI requirements early in product development can prevent approval delays. For project teams, selecting experienced seismic engineers helps ensure that equipment support systems are evaluated correctly from design through installation.

Understanding OSHPD OSP and OPM Pre-Approval Pathways

The two primary pathways associated with healthcare equipment seismic approval are OSP and OPM. Understanding the difference between these pathways is essential for manufacturers, engineers, and contractors working on HCAI-regulated projects.

The correct pathway depends on whether the equipment is a standardized manufactured product or a project-specific installation requiring site-based engineering evaluation.

OSHPD OSP Pre-Approval for Manufactured Equipment

OSHPD OSP pre-approval, now commonly associated with HCAI’s equipment approval process, allows manufacturers to obtain seismic approval for standardized equipment models before individual projects begin.

This pathway is especially valuable for manufacturers that supply equipment to multiple hospitals throughout California. Instead of repeating the same seismic evaluation for every installation, approved equipment can be referenced during future projects.

OSP approval typically requires documentation demonstrating that the equipment meets applicable seismic performance requirements. Depending on the equipment type, this may include:

For equipment requiring dynamic qualification, ICC-ES AC156 shake table testing is commonly used as a recognized method for evaluating seismic performance.

The AC156 protocol simulates earthquake conditions and measures whether equipment can maintain structural integrity and functional performance during seismic events.

Manufacturers must also ensure that the approved configuration matches the equipment installed in the field. Changes to dimensions, weights, internal components, mounting methods, or support conditions may require additional engineering review.

OSHPD OPM Pre-Approval for Project-Specific Installations

OPM approval is generally associated with project-specific equipment installations where engineering evaluation is required for a particular healthcare facility.

Unlike standardized OSP approval, OPM review often considers installation-specific conditions such as:

For example, a medical imaging system installed on a specific floor of a hospital may require evaluation of the supporting structure, anchorage design, and installation details.

A structural engineer may need to verify seismic forces, anchor capacity, concrete conditions, and connection details according to applicable standards.

OPM-related engineering frequently involves PE/SE stamped calculations and coordination between the equipment manufacturer, contractor, and project engineer.

The distinction between OSP and OPM is important because selecting the wrong approval pathway can create unnecessary delays during plan review and construction.

A well-planned certification strategy identifies approval requirements early, allowing manufacturers and project teams to prepare the correct documentation before submission.

Hospital Equipment Seismic Certification Requirements Under HCAI

Healthcare facilities depend on a wide range of equipment and support systems that must continue operating during and after seismic events. Unlike typical commercial buildings, hospitals are classified as essential facilities because interruptions can directly affect patient care, emergency response capabilities, and community recovery after an earthquake.

OSHPD seismic certification addresses the need to verify that critical equipment can withstand earthquake demands while maintaining structural integrity and, when required, operational functionality. The certification process considers not only the equipment itself but also the connections, supports, restraints, and building interfaces that influence seismic performance.

For engineers and facility managers, seismic qualification begins with understanding the equipment’s role, installation environment, and required performance level. Equipment that appears stable under normal operating conditions may experience significant dynamic forces during an earthquake. Without proper seismic design, equipment can slide, overturn, disconnect from utilities, or damage adjacent systems.

Medical Equipment Categories Requiring Seismic Qualification

Many categories of hospital equipment require seismic evaluation because they support essential healthcare operations. The specific approval pathway depends on the equipment type, installation conditions, and applicable HCAI requirements.

Common examples include:

MRI Equipment and Medical Imaging Systems

Magnetic resonance imaging systems, CT scanners, X-ray systems, and other diagnostic imaging equipment often require detailed seismic evaluation because of their size, weight, precision requirements, and connection to building utilities.

These systems may include sensitive internal components that require protection from excessive movement. Seismic restraints must be designed to limit displacement while avoiding interference with equipment operation.

Emergency Power and Electrical Equipment

Generators, switchgear, transformers, battery systems, and emergency electrical components are critical for hospital continuity. Their seismic qualification typically includes evaluation of equipment anchorage, structural supports, and connections.

Failure of emergency power systems after an earthquake can significantly reduce a hospital’s ability to provide uninterrupted care.

HVAC and Mechanical Equipment

Heating, ventilation, and air conditioning systems support infection control, operating rooms, laboratories, and patient environments.

Equipment such as air handling units, pumps, chillers, and mechanical systems may require seismic restraints, vibration isolation evaluation, and anchorage verification.

Medical Gas Systems

Medical gas piping and support systems are essential components of healthcare facilities. Their seismic design must consider movement, support spacing, bracing requirements, and connection integrity.

Fire protection systems must also comply with seismic bracing requirements established by standards such as NFPA 13.

Why Nonstructural Components Matter in Healthcare Facilities

A common misconception is that seismic safety focuses only on the building structure. In reality, many earthquake-related failures occur because nonstructural components were not adequately designed or restrained.

ASCE 7-22 Chapter 13 specifically addresses seismic design requirements for nonstructural components attached to buildings. These requirements recognize that equipment, architectural components, and mechanical systems can create significant risks if they fail during an earthquake.

For hospitals, nonstructural failures can result in:

A properly designed seismic system evaluates:

This approach ensures that seismic forces transfer safely from the equipment through anchors and supports into the building structure.

For hospital projects, seismic certification is therefore not simply a documentation requirement. It is part of a broader resilience strategy that supports continued healthcare operations after seismic events.

Codes and Standards Governing OSHPD Seismic Certification

Successful healthcare seismic certification requires coordination between multiple engineering standards. No single code provides every requirement for equipment qualification, anchorage design, testing, and installation.

Engineers must evaluate the relationship between building codes, seismic design standards, testing protocols, and project-specific requirements.

ASCE 7-22 Chapter 13 Nonstructural Component Design

ASCE 7-22 Chapter 13 is one of the primary references for seismic design of nonstructural components. It establishes requirements for components attached to buildings, including equipment, mechanical systems, and electrical systems.

The chapter addresses important design considerations such as:

For healthcare facilities, many components have increased importance because their failure can affect building functionality.

Engineers must determine appropriate seismic demands and verify that equipment supports and connections can resist these forces.

For example, an HVAC unit mounted on vibration isolators may require evaluation of both operating vibration performance and seismic restraint performance. A system designed only for vibration control may not provide adequate earthquake resistance without additional seismic restraint features.

California Building Code (CBC) and IBC Requirements

The California Building Code incorporates seismic provisions based on the International Building Code while adding state-specific requirements appropriate for California’s seismic environment.

Healthcare projects must comply with CBC requirements along with HCAI review standards.

The International Building Code provides foundational requirements related to:

Coordination between the IBC, CBC, and ASCE 7-22 ensures that equipment installations are evaluated consistently within the overall building seismic design framework.

ACI 318-19 Chapter 17 Anchor Design Requirements

Anchorage design is one of the most critical elements of equipment seismic certification.

ACI 318-19 Chapter 17 provides requirements for concrete anchoring systems, including:

A seismic anchorage calculation must consider factors such as:

Improper anchor selection or installation can compromise an otherwise compliant seismic system.

For this reason, PE/SE stamped seismic anchor calculations are often required to demonstrate that equipment connections satisfy applicable code requirements.

The Role of ICC-ES AC156 Shake Table Testing in Equipment Qualification

Shake table testing provides one of the most important methods for demonstrating the seismic performance of manufactured equipment.

While calculations can verify anchorage and support design, dynamic testing evaluates how equipment responds when subjected to simulated earthquake motion.

When Shake Table Testing Is Required

Not every piece of equipment requires physical testing. The need depends on factors such as equipment type, approval pathway, manufacturer requirements, and project specifications.

For many manufactured products, ICC-ES AC156 is widely recognized as an industry benchmark for seismic qualification testing.

Equipment commonly evaluated through shake table testing includes:

During testing, equipment is subjected to controlled earthquake simulations representing seismic demands expected in real-world conditions.

Engineers evaluate whether the equipment:

How AC156 Testing Supports HCAI Approval

ICC-ES AC156 testing provides manufacturers with documented evidence of seismic performance.

A complete qualification package may include:

For manufacturers seeking broader acceptance in California healthcare projects, AC156 testing can simplify the approval process by providing recognized seismic performance data.

However, testing alone does not replace engineering evaluation. Equipment installation conditions, anchorage design, and project-specific requirements must still be addressed.

A complete OSHPD seismic certification strategy combines testing when needed with engineering calculations, documentation review, and code compliance verification.

Seismic Anchorage Design for OSHPD Approved Equipment

Seismic anchorage is one of the most important components of healthcare equipment qualification. Even when equipment has successfully completed seismic testing or received manufacturer certification, the final installation must still demonstrate that the equipment can safely transfer earthquake forces into the supporting structure.

A complete OSHPD seismic certification process requires evaluation of the entire load path, beginning with the equipment connection points and continuing through anchors, supports, and the building structure.

The objective is to ensure that seismic forces are resisted without anchor failure, excessive movement, equipment overturning, or damage to surrounding systems.

PE/SE Stamped Seismic Anchor Calculations

PE/SE stamped seismic anchor calculations provide engineering verification that equipment anchorage complies with applicable codes and project requirements.

These calculations typically evaluate:

Under ACI 318-19 Chapter 17, engineers must evaluate various failure modes associated with concrete anchorage systems. These include concrete breakout, pullout failure, side-face blowout, bond failure for adhesive anchors, and steel failure.

For hospital equipment installations, anchor calculations must also consider the importance of maintaining operational reliability. A failure involving emergency power equipment, imaging systems, or critical medical infrastructure can significantly affect healthcare operations.

Engineers preparing seismic anchorage documentation must coordinate equipment data with structural conditions. Accurate information such as equipment weight, center of gravity, mounting configuration, and support geometry is essential for producing reliable calculations.

Panache Engineering provides PE/SE stamped seismic calculations designed to support HCAI-regulated healthcare projects, equipment manufacturers, and construction teams requiring technically complete engineering documentation.

Equipment Anchorage Systems and Hardware Selection

The selection of anchorage hardware depends on the equipment type, structural conditions, and applied seismic forces.

Common anchorage components include:

Each anchorage method has advantages and limitations depending on the installation environment.

For example, post-installed anchors may be practical for existing facilities or retrofit applications, while cast-in-place anchors may be preferred in new construction where embedment planning occurs during structural design.

Equipment support frames and steel assemblies must also be evaluated for strength and stiffness. In some cases, structural steel supports are required to distribute loads between equipment and the building structure.

Proper seismic anchorage design requires more than selecting an anchor size. Engineers must verify the complete connection system and ensure that all components work together as a reliable seismic load path.

Seismic Bracing Requirements for Hospital MEP Systems

Hospital mechanical, electrical, and plumbing systems are essential components of healthcare operations. Their seismic performance is directly connected to patient safety, facility functionality, and emergency response capability.

Seismic bracing requirements apply to many MEP systems, including piping, ductwork, conduit, cable trays, and fire protection systems.

ASCE 7-22 Section 13.6 and NFPA 13 provide important guidance for seismic restraint of these systems.

HVAC and Mechanical Equipment Seismic Restraints

Mechanical systems require careful coordination because many components perform two different functions:

  1. Control vibration during normal operation

  2. Resist earthquake forces during seismic events

A vibration isolation system designed only for operational performance may not provide adequate seismic restraint.

For example, air handling units installed on spring isolators may require additional seismic restraint systems to prevent excessive movement during earthquakes.

Mechanical equipment evaluations often consider:

Proper engineering ensures that vibration control and seismic protection work together without reducing system performance.

Electrical and Medical System Seismic Protection

Electrical and medical support systems are among the most critical components in healthcare facilities.

Examples include:

These systems require reliable seismic support because their failure can interrupt essential hospital functions.

Medical gas systems, for example, require careful attention to support spacing, connections, and bracing to prevent damage during seismic movement.

Electrical systems require evaluation of equipment anchorage, cabinet stability, and connection integrity.

A coordinated seismic design approach helps ensure that critical hospital systems remain available when they are needed most.

Common Challenges That Delay HCAI Seismic Approval

Many healthcare projects experience delays not because the equipment cannot meet seismic requirements, but because documentation, coordination, or engineering information is incomplete.

Understanding common approval challenges helps project teams avoid unnecessary revisions.

Incomplete Engineering Documentation

One of the most frequent issues involves missing or inconsistent documentation.

Common problems include:

For HCAI review, technical documentation must clearly demonstrate how equipment meets seismic requirements.

Engineering packages should provide a complete connection between testing data, calculations, drawings, and installation procedures.

Coordination Between Manufacturers and Project Teams

Successful certification requires collaboration between multiple stakeholders:

Manufacturers must provide accurate equipment information. Engineers must evaluate installation conditions. Contractors must install systems according to approved documents.

Poor communication between these groups can result in redesigns, approval delays, and construction conflicts.

Early involvement of seismic engineers helps identify compliance issues before they affect project schedules.
