Quiénes somos
Ofrecemos servicios TIC para mejorar la seguridad contra incendios, la seguridad humana y la seguridad eléctrica a nivel mundial, garantizando el cumplimiento y reduciendo riesgos.
PFS TECO, an NFPA Global Solutions company provides independent third‑party comprehensive support for modular construction projects from QA manual review to final inspections for industrialized modular structures and equipment enclosures evaluated under applicable codes, standards, and state or local approval programs.
Our compliance support services help manufacturers align regulatory expectations, support approval processes, and demonstrate readiness for jurisdictional review, inspection, and market deployment.
Industrialized modular structures and equipment enclosures may be reviewed under different regulatory pathways depending on jurisdiction, classification, and intended use. Requirements and approval processes can vary significantly between state programs and Authorities Having Jurisdiction.
When regulatory expectations are not clearly aligned early, manufacturers may face inconsistent interpretations, changing documentation requirements, and late-stage review issues. These challenges often result in approval delays, redesign, or jurisdiction specific rework, particularly when the same structure is deployed across multiple locations.
Clear documentation and early regulatory coordination help reduce uncertainty and support a more predictable plan review and inspection process, while final approval authority remains with the applicable AHJ or state program.
Our industrialized modular structures and equipment enclosures compliance services are scoped based on the regulatory pathway and approval framework established by the applicable Authority Having Jurisdiction or state modular program.
Manufacturers typically engage these services prior to fabrication or during regulatory review, including when structures require evaluation under state modular programs or local building code pathways.
These services are commonly used by manufacturers of industrialized and prefabricated systems, including equipment enclosures, modular data centers, battery energy storage systems (BESS), utility and energy structures, skidded systems, and other specialized assemblies.
Key Capabilities Include
A well‑aligned compliance approach can help streamline plan review, reduce late‑stage design changes, and improve coordination between manufacturers and reviewing authorities. This supports more consistent interpretation of requirements and reduces jurisdiction‑specific rework.
For manufacturers operating across multiple states, consistent documentation and review practices support greater standardization and repeatability, helping manage schedules, control costs, and maintain confidence throughout the approval and inspection process.
ANSI National Accreditation Board
Applicable standards are determined based on classification, use, and deployment location.
Classification is determined by the applicable state program or Authority Having Jurisdiction based on design, use, installation, and deployment. We support this process by evaluating applicable requirements and documenting information used by AHJs or states to determine the appropriate approval path.
Early engagement during design is recommended. Addressing regulatory considerations before fabrication helps reduce the risk of redesign, approval delays, and jurisdiction‑specific issues later in the project.
Yes. We support AHJs and state programs through plan review, technical evaluation, and inspection support aligned with their review processes. Final approval decisions remain with the AHJ or state authority.
Yes. We support manufacturers operating across multiple jurisdictions by helping align documentation, review scope, and inspection practices with varying state and local requirements. Recognition of prior approvals varies by state and is subject to jurisdictional acceptance.
Manufacturers of prefabricated or industrialized systems such as equipment enclosures, data centers and telecom shelters, skidded systems, battery energy storage systems (BESS) and utility structures, industrial process modules, and other specialized assemblies requiring jurisdictional evaluation.
