OSHPD Pre Approval: OSP, OPM, and Seismic Compliance

Wiki Article

OSHPD pre approval remains an important search term for equipment manufacturers, structural engineers, contractors, and healthcare project teams working on seismic compliance in California. Although the former Office of Statewide Health Planning and Development is now part of the California Department of Health Care Access and Information (HCAI), the OSHPD name continues to appear in construction specifications, equipment submittals, engineering discussions, and preapproval searches.

For projects involving hospitals and other healthcare facilities under HCAI jurisdiction, understanding the applicable seismic approval pathway is essential to coordinating equipment qualification, anchorage design, supporting structures, and construction documentation. A product that has undergone seismic testing is not automatically compliant with every project requirement. Its qualification evidence must be evaluated against the applicable criteria, equipment configuration, mounting conditions, and intended installation.

The distinction between Special Seismic Certification Preapproval (OSP), preapproval of a manufacturer's certification for supports and attachments (OPM), and other applicable HCAI pathways can influence engineering scope, procurement decisions, and project schedules. Identifying the correct pathway early helps project teams avoid incomplete submittals, unnecessary redesign, and discrepancies between approved documentation and installed equipment.

Panache Engineering Inc., based in Arcadia, California, provides specialized structural and seismic engineering services for healthcare facilities, equipment manufacturers, MEP contractors, and engineering teams. Its capabilities include HCAI/OSHPD preapproval support, seismic anchorage calculations, nonstructural component design, seismic bracing, vibration isolation, and engineering documentation.

This guide explains how oshpd pre approvalrelates to HCAI requirements, how OSP and OPM differ, what technical information may be required, and how seismic qualification and anchorage design work together. It also outlines practical steps manufacturers and project teams can take to prepare for engineering review and obtain a project-specific proposal.

What Is OSHPD Pre Approval and How Does It Relate to HCAI?

OSHPD pre approval is a widely used industry phrase for approval pathways associated with seismic qualification and certain equipment or system applications in California healthcare construction. HCAI is the current agency name, while OSHPD remains familiar terminology among engineers, contractors, manufacturers, and healthcare facility professionals.

The distinction matters because an approval is not simply a general statement that a product is earthquake-resistant. It relates to a defined scope, supporting engineering evidence, and the requirements of the applicable HCAI program.

Why OSHPD Terminology Still Appears in Hospital Construction

Legacy terminology remains common in specifications, project records, procurement documents, and online searches. A contractor may request OSHPD-approved equipment, while a manufacturer may need clarification about the applicable HCAI preapproval program.

Project teams should identify the current program and its requirements rather than relying exclusively on older terminology or informal descriptions.

What HCAI Preapproval Is Intended to Establish

Depending on the program, preapproval may address the seismic qualification of equipment, the design of supports and attachments, or qualifying prefabricated components and systems. The documentation establishes the limits and conditions under which the approved design or certification applies.

Equipment identification, mounting details, seismic test evidence, calculations, and installation requirements may all form part of the technical evaluation.

When Preapproval and Project-Specific Engineering May Be Relevant

Not every hospital equipment item follows the same approval route. The appropriate approach depends on the equipment category, applicable regulations, project specifications, and installation conditions.

For example, a manufacturer developing a standardized electrical enclosure for repeated hospital installations may need a different scope of evaluation from a contractor installing a particular mechanical unit on a project-specific support frame.

Early coordination between the manufacturer, structural engineer, MEP team, and general contractor helps determine the required documentation before procurement and installation decisions become difficult to change.

What Is the Difference Between OSHPD OSP, OPM, and PCS?

Selecting the correct pathway is one of the most important early decisions in an HCAI-related seismic compliance effort. OSP, OPM, and PCS are distinct program designations, and their scopes should be confirmed against current HCAI requirements.

OSP: Special Seismic Certification Preapproval

OSP is associated with special seismic certification of qualifying nonstructural components and equipment. The engineering evidence may include seismic qualification testing, equipment configuration information, performance criteria, and supporting documentation.

A manufacturer seeking to use an OSP pathway should establish which product models, configurations, mounting conditions, and limitations are covered. A report for one configuration should not automatically be treated as evidence for every related product.

OPM: Preapproval of Manufacturer's Certification

OPM is associated with the preapproval of a manufacturer's certification for qualifying supports and attachments. Its engineering focus includes the support or attachment design and the way seismic loads transfer through the relevant components.

This distinction is important when equipment mounting systems, support frames, or anchorage assemblies are part of the compliance scope. An OPM designation should not be interpreted as blanket seismic certification for every device connected to the approved support.

PCS: Preapproved Prefabricated Components and Systems

PCS addresses qualifying prefabricated components and systems through a separate pathway. Its applicability depends on the type of assembly and the governing program requirements.

It should not be treated as interchangeable with OSP or OPM simply because all three may appear in healthcare construction documentation.

How to Identify the Appropriate Pathway

Begin by defining the product or assembly, its intended installation, and the compliance question that must be resolved. Determine whether the principal concern is equipment seismic certification, support and attachment design, or a prefabricated system.

Panache Engineering's HCAI OSP certification services, HCAI OPM certification services, and OSP, OPM, and PCS comparison guide provide relevant starting points for defining the engineering scope.

Which Equipment and Systems May Need OSHPD Preapproval?

The equipment involved in healthcare construction ranges from mechanical plant systems to electrical distribution equipment and specialized medical devices. Whether a particular product needs preapproval depends on the applicable HCAI requirements and project-specific compliance pathway.

Mechanical and HVAC Equipment

Chillers, air-handling units, pumps, and other mechanical equipment may require evaluation of their seismic performance, mounting arrangements, and supporting systems.

The engineering scope may involve the equipment enclosure, base frame, support structure, vibration isolation assembly, and connections to the building. For suspended equipment, the load path may also involve threaded rods, trapeze supports, seismic restraints, and structural attachment points.

Electrical and Emergency Power Equipment

Generators, switchgear, transformers, electrical enclosures, and uninterruptible power supplies can be important to continued healthcare facility operations. Their evaluation may involve equipment configuration, anchorage, internal components, and connections to supporting structures.

Where applicable, IEEE 693 may be relevant to electrical substation equipment qualification, but it is not a universal substitute for HCAI requirements or other governing criteria.

Medical Equipment and Specialized Installations

Imaging equipment, laboratory systems, and specialized medical devices may present unique mounting and operational constraints. An MRI installation, for example, can involve equipment-specific support requirements and vibration considerations in addition to seismic design.

The project team should confirm the required pathway for the specific device rather than assuming that all medical equipment has identical preapproval obligations.

Distribution Systems and Seismic Supports

Piping, ductwork, conduit, cable tray, and fire sprinkler systems require appropriate support and seismic restraint design where applicable. ASCE 7-22 Section 13.6 and NFPA 13 can be relevant to qualifying distribution systems and sprinkler bracing.

These requirements are related to, but distinct from, the preapproval of individual equipment assemblies. Coordination across equipment, distribution systems, and building attachments is necessary to achieve a coherent seismic load path.

What Are the OSHPD Preapproval Requirements for Hospital Equipment?

The requirements depend on the selected program, equipment category, applicable code edition, and intended installation. Nevertheless, several engineering principles apply broadly: identify the exact configuration, establish the governing criteria, provide adequate qualification evidence, and document the conditions under which the design is valid.

Equipment Identification and Configuration Control

The submission should clearly identify the manufacturer, model, dimensions, operating weight, center of gravity, mounting arrangement, and relevant configuration options.

Configuration control matters because changes to internal components, enclosure dimensions, base plates, mounting holes, or support frames may affect seismic response and attachment forces.

If a manufacturer intends to offer several related models, the engineering team must establish which models are covered by the available evidence and whether additional analysis or testing is needed.

Seismic Qualification and Performance Evidence

Depending on the applicable pathway, evidence may include shake table test reports, engineering analysis, documented acceptance criteria, and supporting calculations.

The evaluation should establish the relevance of the evidence to the proposed configuration and installation. A product description stating that equipment is earthquake-resistant is not a substitute for technical documentation demonstrating performance against the applicable criteria.

Drawings, Calculations, and Supporting Documentation

A technically useful package may include equipment outline drawings, mounting details, support and anchorage calculations, qualification reports, installation instructions, and product identification records.

For anchorage, the information should allow the engineer to identify the substrate, anchor type, embedment, edge distances, spacing, and applicable connection demands.

The exact submission requirements must be confirmed through the current HCAI program documentation.

Applicable Code Editions and HCAI Review Criteria

The California Building Code (CBC), referenced editions of ASCE 7, applicable HCAI requirements, and project specifications establish the design framework. The International Building Code (IBC) provides a model-code basis, but the code edition adopted for the project and its California amendments govern where applicable.

A design prepared using an assumed code edition may need revision if the project has different requirements. Confirming the governing criteria at the start reduces the risk of incompatible calculations and incomplete submittals.

How Does the OSHPD Pre Approval Process Work?

A structured workflow helps manufacturers and project teams identify engineering needs before procurement or construction activities become dependent on an unresolved approval question.

Step 1: Define the Equipment and Approval Scope

Identify the product, model family, installation conditions, and intended application. Determine whether the issue concerns equipment qualification, supports and attachments, a prefabricated system, or project-specific engineering.

The initial scope should also identify the parties responsible for product documentation, structural design, testing, and application coordination.

Step 2: Review Existing Qualification and Design Documentation

Gather available seismic test reports, calculations, drawings, installation instructions, and existing approval records.

The review should establish whether the documents correspond to the proposed equipment configuration and applicable criteria. Older documentation may still be useful, but its relevance must be evaluated rather than assumed.

Step 3: Complete the Required Engineering Analysis and Testing

Depending on the scope, the work may involve seismic qualification testing, analytical evaluation, anchorage design, support calculations, or detailed connection design.

For example, a manufacturer may have a qualifying equipment test report but still need engineering work to establish that a proposed mounting arrangement is appropriate for the project.

Step 4: Prepare and Submit the Application Package

The engineering team prepares the documentation required by the relevant program, using consistent equipment identification, drawings, calculations, and supporting evidence.

Submission procedures and required documents should be verified against the current HCAI instructions.

Step 5: Address Review Comments and Maintain Configuration Consistency

Review comments may require clarification, revised calculations, updated drawings, or additional evidence. Responses should address the specific technical issue and remain consistent across the document package.

If the equipment changes during review, the team should assess whether the change affects the qualification basis or application scope.

How Does ICC-ES AC156 Shake Table Testing Support Seismic Qualification?

ICC-ES AC156 provides acceptance criteria used in seismic qualification testing of nonstructural components through simulated earthquake motion. When applicable to the equipment and approval pathway, shake table testing can help demonstrate how a component responds to prescribed seismic excitation.

What AC156 Testing Evaluates

Testing subjects a defined specimen to specified motion and evaluates its performance against the applicable acceptance criteria. Depending on the equipment, relevant observations may include structural integrity, attachment performance, operational condition, and evidence of unacceptable damage.

The required test program must be established for the intended qualification. AC156 should not be assumed to apply identically to every product or to replace other applicable requirements.

Equipment Setup, Mounting, and Test Configuration

The tested specimen and its mounting arrangement must be documented carefully. Equipment mass, center of gravity, attachment locations, support stiffness, and mounting details can affect the response observed during testing.

A test result is meaningful only within the limits of its documented scope. If the proposed installation differs materially from the test setup, an engineering review may be necessary to establish whether the results remain applicable.

Test Reports and Engineering Interpretation

A test report should identify the specimen, configuration, test setup, applied motions, instrumentation where relevant, observations, and acceptance criteria. Engineering interpretation connects these findings to the intended application.

For manufacturers, a well-defined qualification record can also help maintain consistency across product models and future revisions.

When Additional Testing or Analysis May Be Necessary

Changes to the enclosure, mass distribution, mounting, or support arrangement can affect whether existing evidence remains relevant. Depending on the change and governing criteria, the appropriate response may be additional testing, analytical evaluation, or a documented determination that the existing evidence remains applicable.

Panache Engineering can support seismic qualification planning and related engineering coordination within an agreed project scope.

How Are Seismic Anchorage and Supports Designed for HCAI Projects?

Seismic qualification and anchorage design address different parts of the same engineering problem. Qualification evaluates equipment performance under defined conditions, while anchorage design establishes how the resulting forces transfer safely into the supporting structure.

Seismic Forces Under ASCE 7-22 Chapter 13

ASCE 7-22 Chapter 13 addresses seismic design requirements for nonstructural components. The applicable force calculations depend on parameters such as component importance, building response, installation elevation, and the governing design criteria.

The engineer must verify the applicable provisions and project assumptions rather than applying a generic force to every equipment item.

Anchor Design Under ACI 318-19 Chapter 17

Where applicable to the governing code and project, ACI 318-19 Chapter 17 provides requirements for anchoring to concrete. The design may require checks for steel strength, concrete breakout, pullout, pryout, and combined tension and shear.

Anchor selection alone does not establish capacity. Embedment, spacing, edge distance, concrete properties, cracked-concrete conditions, installation method, and the forces delivered by the equipment all affect the design.

Post-installed mechanical anchors and adhesive anchors must also have appropriate qualification and installation documentation for the intended application.

Supports, Bracing, and the Complete Load Path

The load path may extend from equipment mounting points through base plates, brackets, support frames, anchors, and the building's structural system. Each element must be evaluated for the relevant demands and connection conditions.

For mechanical and electrical distribution systems, seismic bracing design must be coordinated with the supported services, attachments, and surrounding construction. NFPA 13 requirements should be addressed where sprinkler systems are involved.

PE/SE-Stamped Calculations and Installation Details

Engineering calculations and drawings should clearly identify design criteria, load assumptions, connection geometry, anchor specifications, and installation constraints.

Panache Engineering provides PE/SE-stamped seismic anchorage calculations and related support design within the scope of applicable project requirements. Its seismic anchor calculation request form is a practical starting point for submitting project information.

What Documentation Should Manufacturers and Contractors Prepare?

A complete documentation package helps engineers assess the scope efficiently and reduces avoidable requests for missing information. The exact requirements vary by approval pathway, so the following checklist should be treated as a preliminary coordination aid.

Manufacturer and Equipment Information

Prepare the manufacturer name, model number, equipment dimensions, operating weight, center-of-gravity information, mounting details, and available configuration records.

Existing test reports and approval documents should be included where available. If several models are proposed, identify the differences between them instead of presenting the family as a single configuration.

Engineering and Test Documentation

Depending on the scope, the package may require equipment drawings, seismic qualification reports, anchorage calculations, anchor evaluation documentation, installation instructions, and the applicable design criteria.

Calculations should be traceable to the actual equipment configuration and proposed installation. If an anchor is attached to a steel support rather than directly to concrete, the design should document the relevant steel connection and load path as well.

Project-Specific Information

Provide the project location, equipment installation location, supporting structure details, concrete or steel substrate information, project specifications, and known HCAI review requirements.

This information helps distinguish a product-level qualification effort from a project-specific installation design.

Before submission, verify that the documents use consistent model identifiers, revisions, weights, mounting details, and code assumptions. The current program-specific HCAI checklist remains the governing reference for application completeness.

What Causes Delays or Revisions in OSHPD Preapproval Submittals?

Delays often arise from inconsistencies between the equipment, the engineering evidence, and the installation proposed for the project. Identifying these issues before submission is more efficient than resolving them after review comments have been issued.

Mismatches Between Tested and Proposed Equipment

A tested specimen may differ from the proposed model in mass, enclosure geometry, internal components, mounting locations, or support stiffness. These differences can affect the applicability of the qualification evidence.

Manufacturers should maintain clear configuration records and seek an engineering assessment when changes could affect seismic response.

Incomplete Anchorage Calculations or Connection Details

Calculations that omit anchor spacing, embedment, concrete properties, steel connection details, or load-transfer assumptions can be difficult to verify. Drawings that do not match the calculations introduce further uncertainty.

A coordinated engineering package should allow the reviewer to trace the relevant demands through the equipment attachments and into the supporting structure.

Incorrect Approval Pathway or Code Basis

Confusing OSP, OPM, and PCS can lead to a package that does not address the required technical scope. Similarly, using an incorrect code edition can affect calculations and documentation.

Confirm the applicable pathway, code basis, and submission requirements before investing in testing or finalizing the engineering package.

Uncontrolled Product Revisions

A change introduced during manufacturing or procurement can create discrepancies between the approved documentation and delivered equipment. Establish revision controls so that changes are documented and evaluated for their effect on the existing qualification or design.

For existing facilities, FEMA E-74 can provide useful guidance for assessing nonstructural earthquake risks and identifying mitigation opportunities. It does not replace project-specific engineering or HCAI preapproval requirements.

How Much Does OSHPD Pre Approval Cost, and How Long Does It Take?

Cost and schedule depend on the required approval pathway and the amount of engineering evidence already available. A product with complete, relevant qualification documentation may require a different scope from a new product that needs testing, analytical work, support design, and a complete documentation package.

Factors That Influence Engineering Costs

Important factors include equipment complexity, the number of models, the quality of existing test data, required analysis, anchorage design, drawing development, and anticipated coordination or review effort.

Testing costs, laboratory scheduling, and additional work arising from design revisions may also affect the total project budget. An estimate should distinguish engineering services from external testing costs and other project expenses.

Factors That Influence Schedules

The timeline depends on documentation completeness, engineering complexity, testing availability, application requirements, and review comments. Product changes during the process can create additional work.

Engineering preparation, laboratory testing, and agency review are separate stages. No universal schedule should be assumed for all equipment or preapproval programs.

What to Include When Requesting an Engineering Quote

A useful request includes equipment specifications, current drawings, weight and mounting information, existing qualification reports, project requirements, and the desired deliverables.

If some information is unavailable, identify the gaps clearly. This allows the engineering team to define assumptions, exclusions, and next steps.

Frequently Asked Questions About OSHPD Pre Approval

What is OSHPD pre approval?

OSHPD pre approval is a commonly used term for preapproval pathways associated with California healthcare facility construction, now administered under HCAI. The applicable pathway depends on the equipment, support system, or prefabricated assembly and the governing requirements.

What is the difference between HCAI OSP and OPM preapproval?

OSP concerns special seismic certification of qualifying equipment or components. OPM concerns preapproval of a manufacturer's certification for qualifying supports and attachments. Their scopes differ, so the applicable program should be confirmed before preparing the submission.

Is OSHPD pre approval required for all hospital equipment?

No. Requirements depend on the equipment, intended use, governing code, HCAI criteria, and project specifications. The design team should determine the applicable compliance pathway rather than assume every hospital item requires the same approval.

Does OSP preapproval eliminate the need for seismic anchorage calculations?

Not automatically. Equipment qualification and anchorage design address separate aspects of seismic performance. Project-specific anchorage calculations or installation details may still be necessary to demonstrate that the proposed connections and supporting structure satisfy the applicable requirements.

Does OPM preapproval certify the equipment itself?

OPM focuses on the manufacturer's certification for qualifying supports and attachments. It should not be treated as universal seismic certification for every device attached to those supports. The actual approval scope and limitations must be reviewed.

Is ICC-ES AC156 testing required for OSHPD preapproval?

AC156 is an established acceptance criterion for seismic qualification testing of nonstructural components. Whether testing is required, and whether existing test evidence is acceptable, depends on the applicable pathway, qualification criteria, and equipment configuration.

What documents are needed for an OSHPD preapproval application?

Depending on the program, documents may include equipment drawings, mounting details, engineering calculations, seismic qualification reports, installation instructions, product identification, and supporting technical information. The current HCAI checklist for the relevant program should be used to confirm requirements.

How long does OSHPD pre approval take?

The timeline varies with application complexity, documentation completeness, testing needs, and review comments. Engineering preparation, laboratory testing, and agency review are separate activities, so a project-specific schedule is more reliable than a universal estimate.

How much does OSHPD pre approval cost?

Costs depend on the engineering scope, equipment configuration, existing test evidence, number of models, anchorage requirements, and any additional testing or revisions. A detailed quote requires enough information to define the intended approval pathway and deliverables.

Can a manufacturer use existing seismic test reports for a new equipment model?

Possibly. The report's scope, specimen configuration, mounting conditions, acceptance criteria, and differences between models must be evaluated. Acceptance of existing evidence cannot be assumed without checking the applicable requirements.

Who can prepare seismic anchorage calculations for an HCAI-regulated project?

A qualified structural engineering professional can evaluate seismic demands, anchors, connections, and supporting structures against the governing criteria. Where required, calculations and drawings must be stamped by a professional appropriately licensed for the work in California.

How can Panache Engineering help with OSHPD pre approval?

Conclusion: Plan OSHPD Pre Approval Around the Complete Seismic System

OSHPD pre approval is best approached as a coordinated engineering and compliance process. Identifying the appropriate HCAI pathway is only the starting point. Equipment configuration, seismic qualification evidence, support and anchorage design, installation requirements, and documentation must all align with the applicable program and project criteria.

For manufacturers, early qualification planning can help establish a consistent technical basis across product models and reduce uncertainty during procurement. For structural and MEP engineers, coordinating the equipment with its supports and attachments helps maintain a traceable seismic load path. For general contractors and healthcare facility managers, confirming the approval scope before installation can reduce avoidable submittal revisions and construction delays.

The governing California Building Code edition, applicable ASCE 7 provisions, relevant ACI anchorage requirements, and current HCAI program criteria should be confirmed for each project. Where shake table testing is applicable, the test configuration and qualification evidence must correspond to the product and intended use. Where anchorage design is required, the engineer must evaluate the complete connection path rather than relying on equipment certification alone.

Panache Engineering brings together HCAI/OSHPD preapproval support, seismic qualification coordination, PE/SE-stamped calculations, bracing design, vibration isolation, and technical drawing capabilities. This integrated approach can help manufacturers, contractors, and design teams define a practical scope and coordinate the engineering deliverables required for their projects.

The next step is to identify the equipment or system, gather the available drawings and qualification records, and confirm the intended installation and compliance requirements. With a clearly defined scope, the project team can determine which engineering services are needed and request a proposal based on the actual work involved.
