installed to support the irregular column
lines.
On the exterior, the building is clad with
a concrete panel system which has required
numerous connections around the steel
frame’s perimeter. The panels, which weigh
up to 18t each, sit flush to the steelwork
and necessitated flat bolted connections for
the exterior steel splices.
All of the project’s lifting duties are being
carried out by the site’s tower crane.
“This is a typical inner city site with no
space for materials storage and so we had
between two and four steel deliveries every
week, which were immediately erected,”
explains Skanska Senior Engineer Nauman
Soomro.
“In order to keep the many neighbours
happy, which include residents, a hotel
and an art gallery, we were restricted to an
8am to 6pm window for deliveries, all of
which had to be made to the site’s one very
narrow pit lane.”
Bourne Steel completed the main steel
frame in June, but has been scheduled to
return later this year to infill the gap left
once the centrally-positioned tower crane
is removed.
32 Duke Street St James’s is due to be
completed in Spring 2019.
