Quintiles took out a long-term lease to create a new clinical trials unit on the 13th floor of Guy's Hospital in London. CBS was contracted to design and install the plumbing, heating, ventilation and cooling systems for the refurbished floor. Central heating and cooling from the hospital proved insufficient, so CBS supplemented it with additional fan coil units. A building management system was installed to control both the central systems and fan coil units. The refurbishment was completed on time, on budget, and to the satisfaction of both the client and landlord.

1. case study
Guy’s Hospital
Quintiles is one of the world’s leading
providers of pharmaceutical services,
helping to deliver new drugs and cures
for some of the most challenging
diseases.
To increase their capability to perform
this important work, Quintiles recently
took out a long-term lease for the 13th
floor at Guy’s Hospital London - in order
to create a new unit for clinical trials.
The floor needed a total revamp, and so
started with a strip-out all the way back
to the external walls. With everything
removed, the project could then start
with an empty shell.
CBS were called in to design and install
the plumbing, heating, ventilation and
cooling for the new clinic. An important
condition laid down by the hospital was
that any new climate control equipment
would have to use existing services
-presenting some real challenges.
The services available were hot and
chilled water in the central risers, fed
and controlled from a main boiler house
and chiller plant. These circuits provided
heating or cooling duty that could then
be fed into ductwork to provide the
desired temperature for the floor.
However, CBS’ Project Managers
calculated that these centralised services
would provide insufficient heating and
cooling for the floor.
So in order to supplement them, CBS
installed additional Trane fan coil units
around the perimeter. These fan coil
units were fed with the chilled water
from the central riser but also had high
efficiency electric heaters installed,
enabling them to produce additional
heating and cooling as required.
The next challenge CBS faced was how
to give the Quintiles staff control over
their heating and cooling sytems. This
was made difficult by the conditioned air
from the central plant being controlled by
a different system to the additional fan
coil units.
A solution was quickly found and CBS
installed a BMS (building management
system) which was designed specifically
for the installation. This had the ability to
control the additional Trane units as well
as the fan coils around the central riser.
This unique method of local control
made the best use of the building’s
existing plant and given the constraints
laid down by the landlord, worked
suprisingly well.
This was the first installation in which
Guys hospital have ever given one of
their tenants the ability to manipulate
the services from the main plant. The
system also gave Quintiles the ability, via
a touch screen at the nurses station, to
additionally control the extraction of stale
air and the lighting of the floor.
The entire refurbishment of the floor was
finished on time, on budget and to both
the client and landlords specification.
In fact, Quintiles were so happy with the
finished results of the project, that shortly
after completion they hired a film crew
to capture their new facility for corporate
marketing purposes.

2. Local.
Dependable.
Professional.
Safe & Secure
Push fit fittings were used for
all water pipework throughout
the installation. Not only did
this make the installation safer,
as no soldering was required,
but the fittings are also
incredibly strong - Rated for
up to 16 bar of pressure.
ENSURING COMFORT
It was calculated that the
services coming from the
central plant would be
insufficient. So Trane fan coil
units where installed around
the perimeter of the floor
to provide supplementary
heating and cooling.
PEACE OF MIND
Due to the nature of the
building, an advanced water
leak detection system
was fitted underneath the
raised floor. This would
automatically alert the nurses
station and the floor below if
ever there was a problem.
