Data centres are at the core of many organisations. Downtime of the data centre could lead to major losses to the business. As a result, many organisations 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.

The ANSI/TIA-942 Standard specifies requirements and guidelines for the design and build of a data centre. It is intended for use by designers who need a comprehensive understanding of the data centre design. It encompasses Architecture, Mechanical, Electrical and Telecom requirements and guidelines, which are not always covered by other generic guidelines and so-called “standards”. Understanding the intent of the ANSI/TIA-942 Standard is of fundamental importance, not only for the successful implementation of the data centre, but also for its sustainable operations. In this 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. The course is well suited for all types of data centres, be it enterprise data centres or multi-tenant, third party data centres such as co-location, managed services and cloud service providers.

Duration: 3 Days


The primary audience for this course is any professional involved in designing, building, maintaining and operating mission critical data centres and those who wish to attend the CTIA® (Certified TIA-942 Internal Auditor) course.



Participants must possess a valid data centre training certificate such as CDCP® or any other approved equivalent. Please submit a copy of your certificate for verification upon registration for the CTDC® course.

Course Benefits
  • Learn to properly comprehend and apply the ANSI/TIA-942 Standard requirements and guidelines
  • Understand the proper intent of the ANSI/TIA-942 Standard to avoid both over- and/or under-investment
  • Align the selection of redundancy levels and infrastructure investments to the business requirements.
  • Understand the criteria and requirements for a highavailability data centre design and how to effectively establish the data centre from the perspective of the ANSI/TIA-942 Standard
  • Understand how the ANSI/TIA-942 Standard relates to various worldwide standards
Delivery Structure and Methods

The CTDC® course is lectured by an EPI Certified Instructor using a combination of lectures and question-and-answer sessions to discuss participants’ specific needs and challenges experienced in their own data centre environments. Participants are able to tap into the extensive experience of the trainer enabling them to validate and improve their own environments thus adding tremendous business value. The CTDC® course is approximately 80% lecture and 20% hands-on. CTDC® course is available in the following delivery methods:
• ILT – Instructor Led Training
• VILT – Virtual ILT
• TOD – Training On Demand

The classes are available on public schedule as well as private group training.


Certification exams are administered at the end of the last training day by an authorised training partner, either using paper-based or online format, depending on the country in which the course is delivered. The exam is a 90-minute closed book exam, with 60 multiple-choice questions. The candidate requires a minimum of 50 correct answers to pass the exam. Online exam results are known immediately and paper-based exam results will be known within one week.


Candidates who successfully pass the exam will receive the official ‘Certified TIA-942 Design Consultant’ certificate. The CTDC® certificate is issued for the ANSI/TIA-942 version current at the time, which the candidate tested for. The certificate itself does not expire and stays relevant only for the stated ANSI/TIA-942 version.
