Expert Witness in USP <800> Compliant Pharmacy Design and Construction
Bernstein & Associates, Architects, through its principal William N. Bernstein, AIA, has provided expert witness services in matters involving the design and construction of USP <800> compliant pharmacies and hazardous drug compounding facilities and related properties. Attorneys litigating cases that involve construction defects, hazardous drug receiving and unpacking area defects, containment SCA (C-SCA) design failures, negative-pressure containment buffer room design failures, externally vented PEC integration problems, failures to maintain required negative pressure differentials, HEPA filtration and exhaust failures, gowning and anteroom layout defects, hazardous drug storage and segregation failures, surface contamination and cleanability failures, spill-response and containment failures, accessibility violations, fire safety and egress issues, water infiltration and building envelope failures, phased-construction disputes, and other claims related to the design and construction of USP <800> compliant pharmacies require an expert witness architect who understands both the applicable building codes and standards and the practical realities of how USP <800> is applied in the design, construction, and renovation of real hazardous drug compounding facilities.
About USP <800> Compliant Pharmacy Design and Construction
USP <800> compliant pharmacy design and construction encompasses hazardous drug handling and compounding facilities, including hospital oncology compounding suites, ambulatory infusion center hazardous drug compounding rooms, 503A pharmacy hazardous drug compounding facilities, 503B outsourcing facility hazardous drug suites, veterinary hazardous drug compounding facilities, and the support spaces that serve them, including hazardous drug receiving and unpacking areas, hazardous drug storage areas, containment segregated compounding areas (C-SCAs), containment buffer rooms (ISO 7, negative pressure), containment-only externally vented primary engineering controls (CSTDs, BSC Class II Type B2, CACI), anterooms (ISO 7, positive relative to ambient but accounting for the negative containment buffer room), gowning rooms, and spill-response stations.
The design and construction of USP <800> compliant pharmacies is governed by a complex framework of technical standards, including the applicable building code (for example, in New York City, the New York City Building Code), the International Building Code, ICC A117.1, NFPA 101 Life Safety Code, NFPA 99 Health Care Facilities Code, ASHRAE 170, USP General Chapter <800> for handling hazardous drugs in healthcare settings (which prescribes containment requirements, pressurization, PEC selection, external venting, and surface and material requirements), USP General Chapter <797> where the facility also performs sterile hazardous drug compounding, NIOSH hazardous drug list, ISO 14644 cleanroom classification standards, OSHA Hazardous Drugs requirements, state board of pharmacy regulations including state-level adoption of USP <800>, ADA requirements, and state and local department of health requirements.
Disputes commonly arise over construction defects affecting building envelopes, interior finishes, and hazardous drug handling spaces; hazardous drug receiving and unpacking area defects (which require negative pressure relative to ambient); C-SCA design failures including non-compliant negative pressure, air-change rates, and external venting; containment buffer room failures to maintain required negative pressure differentials relative to surrounding spaces; PEC selection problems (failure to use externally vented Class II Type B2 BSCs or CACIs for sterile hazardous drug compounding); HEPA filtration and exhaust design failures including non-compliant routing of exhaust to safe locations; gowning and anteroom layout problems that compromise the containment scheme; hazardous drug storage and segregation failures; surface materials that fail cleanability and decontamination requirements; spill-response and containment design failures; non-compliant accessibility features; inadequate fire-rated assemblies and egress; and disputes arising from phased-construction projects. Responsibility for compliance with the applicable standards is shared, in different ways, among the operator, the landlord, the design professional, the contractor, subcontractors, specialty vendors, and the party responsible for ongoing maintenance, and litigation in this area frequently turns on the allocation of responsibility for design decisions, construction means and methods, and post-occupancy maintenance.
Expert Witness Services Related to USP <800> Compliant Pharmacy Design and Construction
Expert witness services in USP <800> compliant pharmacy design and construction matters typically include a careful review of the project documents (drawings, specifications, submittals, RFIs, change orders, permits, certificates of occupancy, ICRA plans, department of health filings and approvals, lease agreements, commissioning reports, and as-built conditions) (along with cleanroom certification reports, environmental monitoring and wipe-sampling records, HEPA and exhaust certification reports, PEC certification reports, and HVAC validation documentation), a site survey to measure and document the conditions at issue, comparison of those conditions against the applicable building codes, life safety codes, USP <800> and (where relevant) USP <797> requirements, ISO 14644 standards, NIOSH hazardous drug list, accessibility standards, and industry standards of care, review of construction administration records and maintenance histories, and the preparation of clear, well-supported opinions regarding the cause of the defect or failure, the responsibility of the various parties, and the standard of care applicable to the design, construction, and maintenance of USP <800> compliant pharmacies.
An effective USP <800> compliant pharmacy design and construction expert witness must be able to explain technical requirements — USP <800> containment philosophy and the negative-pressure cascade, hazardous drug receiving and storage design, C-SCA design and limitations, containment buffer room design with negative pressure, primary engineering control selection (Class II Type B2 BSCs, CACIs) and external venting, HEPA filtration and exhaust routing, gowning and anteroom layout under USP <800>, surface and material requirements, spill-response design, fire-rated assembly construction, egress geometry, accessibility clearances, and building envelope detailing — in plain language to judges, juries, arbitrators, and mediators, and must have the credentials, written record, and courtroom-ready communication skills to render credible opinions.
Mr. Bernstein is a Yale-trained, NCARB-certified, LEED-accredited, registered architect. He has expertise in architectural design, engineering design, and construction as the founder/owner of an architectural firm, Bernstein & Associates, Architects, (1990-present) and as the founder/owner of a construction project management firm, Empire Projects, Inc.
