Capabilities and Experience – Data Centres
We provide Clients with a unique level of service due to our knowledge of all aspects of the data
centre, from IT hardware through networking to the power, cooling and protection systems, and
not least the physical envelope.
Tuckers Consultancy are able to draw on the knowledge and experience of Barry Shambrook,
John Laban and Phil Turnock who are all qualified instructors for the international DC
Professional education programme. They are augmented by our close knit team of
professionals located at our main office in Canary Wharf, London and a world-wide network of
contacts. We have network, mechanical and electrical design, CAD and BIM (Building
Information Modelling) expertise in house.
Our Consultancy services are tailored to the needs of our Clients and range from strategic to
detailed design, quality control, project management and operational training on new builds. For
existing facilities we can provide capacity reviews, resilience audits and energy efficiency
improvement studies.
Our advice is based on extensive experience but with reference to applicable standards and
recommendations such as ANSI/TIA 942, BICSi 002, Uptime Institute, ASHRAE TC 9.9, Green
Grid, the EU Code of Conduct and CEEDA.
Tuckers Consultancy have no partnership agreements with any vendor or manufacturer. Our
business model does not rely on selling products so we always take a completely independent
view on what is best for our customer.
Case Studies
New build data centre in existing building, South Essex
Our Client had to evacuate their data centre due to a major fire nearby and needed a new
facility within 3 months. Working closely with the Contractor we identified components that could
be obtained at short notice and put them together into a resilient and efficient design located in
a vacant office space that had the advantage of existing data links. We carried out an extensive
IST (integrated systems test) on a temporary power supply and repeated this on the live centre
when the permanent supply became available.
New data centre for Software Company in rural location
The Client on this project wished to incorporate a small data centre into the Grade 2 listed
building on their estate in rural Buckinghamshire. We worked with the Client to ascertain their
resilience and capacity needs, then developed a design that could be accommodated on the
existing power infrastructure with options for later upgrade. The heat rejection design was
particularly challenging due to aesthetic and noise planning restrictions.

Data centre within major office development, Canary Wharf
This firm had taken a leasehold on a purpose built 32 storey tower in Canary Wharf and wished
to incorporate their data centre on site. We worked with the Developer to develop the design of
the data centre and PoP (point of presence) rooms to provide a resilient space which can be
relocated elsewhere in future without disrupting the office networks. The power and cooling
systems were designed to contribute to the BREEAM Excellent energy efficiency rating of the
building, for instance the heat rejected from the data centre is used to heat the office space in
winter.
World-wide data centre strategy
Our Client is an international law firm who wished to consolidate their data centres in each
region into 3 main hub locations. We carried out surveys and provided objective resilience and
capacity evaluations on existing and new site options. We then advised on upgrades required
for the three selected sites in London, Frankfurt and New York, and signed off on completion.
Financial services data centre, City of London
This Client had their main data centre off shore but wished to incorporate a very high resilience
facility in their new London office for absolute minimum latency. Our design was restricted by
the building infrastructure, but by working in close co-operation with the Landlord’s advisors we
achieved the capacity and resilience required.
Defence Contractor facility design review
Our review of the intended design of this small but very important data centre identified some
critical single points of failure, operational restrictions and very poor energy efficiency that had
been driven by security requirements. We showed how improvements could be made to the
design at very little cost that would preserve the security but overcome the other problems.
Data centre energy efficiency surveys
We have recently carried out energy efficiency reviews of two data centres, both with capacities
of around 200 cabinets which have shown annualised PUE’s (in accordance with latest Green
Grid guidance) of around 2.2. In both cases adjustments to the UPS operation and incorporation
of CRAH unit fan speed control will improve PUE to around 1.5, resulting in annual energy
savings of around £80,000 per annum for a capital investment of around £60,000.
