Tier III 2.2mw Site – Data Centre Design

The site was a 1990’s “mothballed” 1,000m2 (net technical) data centre built for an American financial institute. The M&E equipment was originally designed to provide approx. 700 w/m2 power capacity, and the M&E infrastructure was not designed to achieve TUI Tier III resiliency or “concurrently maintainable”.

The new site owner employed a Design & Build Contractor to upgrade the site to 1.5kW/m2 and to meet The Uptime Institute, Tier 3 design topology requirements.

Saradan Design & Management was retained by the site owner as Building Services Consultants to assist in the redesign of the sites M&E infrastructure, oversee the fit out works, commissioning and IST.

Space on site was at a premium due to the lower original M&E plant requirements, this required some creative thinking to “shoehorn” everything in.

Total redesign of the ME systems including “knocking through” rooms to fit in all services.
