Client: Skanska
Location: 110 Bishopsgate, London
Completed: November 2010
Project Type
The Project
Working with Skanska, Fulcrum delivered a new gas supply to a
prestigious building in the center of London, Heron Tower.
About The Site
Heron Tower, also referred to as 110 Bishopsgate, is a
skyscraper constructed by Heron International in the City of
London. Now completed it is the tallest building in London at 230m
(755ft).
Our Approach
We worked in partnership with Skanska, the network National Grid
Gas Plc and Transport for London, as the gas service was installed
in one of the busiest areas of central London.
During the design, planning and construction, we maintained
communication with Skanska to ensure their requirements were fully
met and with Transport for London to minimise disruption to this
busy area during the installation.
The Technical Part
Skanska required a new gas connection to offices and the
restaurant Sky Bar situated on the 40th floor. To obtain the
correct operating pressure we incorporated the use of boosters and
compressors.
The service had to be designed to address engineering
difficulties surrounding the building's construction. For example,
the retaining walls at basement level were constructed in a manner
that meant that the gas service had to be reduced in size to pass
through pre-cast openings.
A Dedicated Delivery
Design Manager Steve Naylor:
"As the primary gas meter was to be located within the building
at basement level, we had to look at ways of elevating the pressure
for the equipment on the 40th floor.
Using experience obtained on previous projects of this nature I
proposed the use of boosters to the client. Using boosters, it
would elevate the meter pressure and we could design the system to
make allowances for the pressure drop over the 40 floors.
Reflecting the way boosters operate and how they can affect the
systems they are connected to, I submitted two designs to the
operating gas network, one for normal conditions and one for
boosted conditions. Both designs were analysed to determine
the rate at which the pressure would increase without affecting the
existing network, before approval was given for the boosted
option."
What Our Customers Say
"Correspondence with the design office was exceptional. We were
kept fully informed of the current progress with the design and
delivery of requirements. Liaison with the site agent was
good, and initial site discussions on dates and install were
progressive."
