Construction projects in the City of
London invariably have to contend
with a host of challenges, notably
the congested nature of the
square mile above ground and the myriad of
infrastructure that can be encountered below
ground.
100 Liverpool Street, which forms
an initial phase of the City’s Broadgate
redevelopment, is a case in point as this site
is situated adjacent to one of the nation’s
busiest railway stations - Liverpool Street
Station - with the terminus’s west entrance
even passing through the site along with a
shopping mall.
Below ground a mass of infrastructure,
including a Central Line tunnel, a disused
Victorian tunnel, various access routes and
substations are all present.
The project consists of two existing
buildings, 100 Liverpool Street and 8-12
Broadgate, which are being reconfigured into
a single structure. All of the substructure is
being retained as well as approximately 50%
of the original steel frames that extend up to
eight-storeys high.
New steelwork is being erected to knit the
structures together, replace the demolished
areas and add four new floors to the top,
creating a new 12-storey landmark building.

One of the first phases of the wider Broadgate redevelopment,
