Data center consultants, designers, builders and auditors all play a critical role is designing, deploying and certifying data centers that conform to the ANSI/TIA-942 standard. Data center owners/operators need confidence and validation that the companies providing these services have the competencies, are stable and well established with a high success rate and holds the right certifications.

Auditors and Auditing Companies

Auditing is required for data centers to achieve ANSI/TIA-942 certification, and audits must be conducted by Conformity Assessment Bodies (CABs) that offer the following benefits and assurance: 

  • Have no conflict of interest and follow ISO audit policies, procedures and processes,
  • Employ competent and qualified auditors with appropriate experience and knowledge of the ANSI/TIA-942 standard and ISO requirements

Note that auditors cannot operate as individuals and must be affiliated and operating under a CAB to provide ANSI/TIA-942 validation and certification services.  If the company/certification body you intend to engage is not listed, they are likely not authorized. Contact to verify.

Consultants/Consulting Companies

When seeking conformity to ANSI/TIA-942, success relies greatly on the competence of consultants and designers and their level of knowledge and experience with the standard. There are many data center design and build companies, as well as organizations and individuals providing consultancy services, and data center owners/operators should avoid individuals providing these services as a “private” person and work with companies that are well-established entities with and have the staff, financial backbone, legal structure and insurance requirements in place. 

Data center owners and operators should adhere to three primary recommendations when evaluating potential consultants and consulting companies:

Validate the Expertise
Standards are living documents and the consultant and/or designer must be familiar with the current version of the ANSI/TIA-942 standard and hold a valid CTDC (Certified TIA-942 Design Consultant) certificate aligned with the current version. 

Verify Qualifications
Check certificates and/or license based on the requirements of the project and your region. Designing a data center requires a team of experts, and it should never be a single person. Designing electrical subsystems for a computer room is very different than designing an incoming high-voltage distribution system, and two may require separate licenses.

Confirm Experience
Ensure that the consultant’s experience is relevant to the project under scope and can be validated by checking on past projects and proving claims of certified data centers. You can validate ANSI/TIA-942 certified data centers at the link below.
