Certified TIA-942 Design Consultant

The Certified TIA-942 Design Consultant (CTDC®) course is a three-day course, the participant will learn how to design an ANSI/TIA-942 compliant data centre. It will provide a clear understanding of the requirements of the ANSI/TIA-942 Standard and possible implementation variations.

EPI and EXIN work together with EXIN Accredited Training Providers (ATP’s) on the EPI Data Center certificates. Therefore you can only book your EPI exams at the official EXIN ATP’s.

Target group

CTDC is a course designed for any professional involved in designing, building, maintaining and operating mission critical data centres and those who wish to attend the CTIA® (Certi­ed TIA-942 Internal Auditor) course.


Data centres are at the core of many organizations. Downtime of the data centre could lead to major losses to the business. As a result, many organizations establish resilience at various levels such as the data centre facilities infrastructure and at the ICT layer. However, following the recommendations from various vendors, consultants and the public domain, information might result in under- or over-specification. Therefore it would be better to follow a commonly accepted standard as the basis for the design and build principles.


  • Participants must possess a valid data centre training certifi­cate such as CDCP® or any other approved equivalent.
  • Evidence of training of CTDC® by an EXIN accredited training provider.
