“By using shallow heavy plate girders
we’ve been able to incorporate one extra
floor level into the planning envelope.”
Steel supports metal
decking to form the
composite floors
where many of the tenants have chosen to
remove the suspended ceiling and expose the
structure,” explains WilkinsonEyre Director
Oliver Tyler.
“This has led to an architectural approach,
whereby the structural steel frame and
steel decking forming the floors has been
exposed. This has resulted in much closer
attention being paid to steel connections and
the detailing and setting out of services and
their penetrations through the beams.”
The design team say that greater care
than normal has been paid to the detail and
location of column splice joints, beam-tocolumn
connections and the detail of steel
suspension hangers.
“Great care has also been taken in
working with McL&H and Severfield to
specify the black paint finish, taking into
account the exposed nature of the steel
within the finished building,” adds Mr Tyler.
For stability, the building features one
concrete core, which is offset and positioned
along the southern elevation. This not only
maximises the available floor space on each
level, but also creates an ‘active’ front to the
building, as the core contains a scenic lift
and staircase, which will be visible through
the glazed cladding.
“The position of the core is also about the
massing of the structure as it is located in
the portion of the building that reaches the
maximum height,” explains Ms Gillies.
