Uptime Tier to ANSI/TIA-942 Upgrade

It is common knowledge that the Uptime Institute Tier Topology guideline only addresses the electrical and mechanical infrastructure of a data centre. Although critical, data centre owners/operators have come to learn that the Uptime Institute’s Tier guidelines are missing some fundamental elements for today’s business critical environments. More and more customers are challenging their Uptime Institute Tier certified data centre operators on why they only have certified their power and cooling infrastructure and left out key elements such as security, network etc. 


TIA-942 is a complete data centre standard as it also addresses site location, architectural aspects, physical security, fire safety, telecommunications, to name a few.  The advantages of TIA-942 Conformity Certification far outweighs those of Uptime Institute Tier Topology Certification. 


3 key reasons why you should consider upgrading from Uptime to ANSI/TIA-942:


  1. Broader Scope
    The Uptime Institute Tier Topology covers only Electrical and Mechanical, whereas the TIA-942 covers the full data centre facilities (Electrical, Mechanical, Telecommunication, Architectural, Site Location, Fire Safety, Physical Security etc), which is critical for today’s mission critical data centres.   
  2. True Standard
    Uptime Institute Tier Topology is a guideline issued by a commercial organisation, whereas TIA-942 is a true Standard issued by an SDO (Standard Development Organisation) accredited by ANSI and applicable globally.  This brings great transparency which is important for any data centre owner/operator. 
  3. Lower Cost
    Uptime Institute assessments are performed by Uptime Institute consultants only and known to be very high-cost whereas TIA-942 assessments are performed by qualified auditors at very completive rates.


TIA-942 is a certifiable standard. EPI is incorporated as a CB – Certification Body and is therefore qualified to certify data centres to the TIA-942 standard.


3 types of upgrade packages. 

  • Uptime Institute Design Documents Certificate to ANSI/TIA-942 Design Certi­ficate
  • Uptime Institute Design Documents Certificate to ANSI/TIA-942 Facilities Certifi­cate
  • Uptime Institute Constructed Facilities Certificate to ANSI/TIA-942 Facilities Certifi­cate

Pricing varies depending on the size and target rating level of a data centre but are often at a fraction of the cost compared to Uptime Institute’s Tier Topology certification.
