Its location is equally
novel, taking up the railway arches between London Bridge and Cannon
Street stations on the south bank of the Thames. Because of the
nature of this site, the PIPE2000 underfloor heating, which was
installed by A G Manly & Co, is designed to remove any dampness
as well as providing the first stage of space heating.
Should the ambient temperatures fall to very low
levels, the underfloor heating will be supplemented by a variable
air volume air conditioning system. An additional benefit of the
underfloor heating is that it allows Vinopolis to make use of the
maximum floor space for display purposes.
Low pressure hot water (LPHW) from the modular
boilers in the plant room supplies both the air handling units and
the underfloor heating system. For the underfloor heating, the flow
temperature of the LPHW is reduced to 60°C by mixing with cold
water before being introduced to the to the vaults via a central
trench. The trench divides via PIPE2000 manifolds into secondary
trenches to serve each arch.
In all, some 3000m2 of heated floor are served
by the system, which is embedded in a flowing anhydrite screed,
supplied ready-mixed to site.
Isocrete Gyvlon is a self-levelling, pump-applied
anhydrite screed that is ideal for fast track contracts as it can
be applied at rates of up to 3000m2/day, depending on the nature
of the project. It is free flowing and fast curing, allowing trafficking
within 24 hours and has virtually no risk of cracking and curing.
The main contractor for the project was Sir Robert
