and motorway services, we were engaged
once again to assist on this cinema project.
Kloeckner Westok provided free design
guidance and calculations to MPA who
were tasked with developing a cost-effective
clear span solution, which fulfilled the
requirement for significant building service
integration within the strict depth limits set
by the architect.
The Westok rafters over the cinema boxes
have 450mm diameter cells and they have all
been manufactured with a full string of cells
to future-proof the MEP integration of the
building.”
The cellular beams also have the benefit
of reducing the external cladding required
and also reducing heat loss through the
envelope.
Overall the structure gets its stability
from cross bracing hidden in each of the
boxes’ partition walls. All of them are
connected by the building’s main concourse,
or street, which adjoins the ground floor
entrance foyer.
The foyer area of the cinema has the
longest clear span in the structure at
20m-long, and this has been created by a
single 1.5m-deep truss weighing 4t.
“The Westoks over the foyer are cut from
UC sections to facilitate the wide flange/
shallow beam solution required in this area.
These beams were restricted to 450mm
maximum depth with sufficient bearing
required to carry the 200mm precast hollow
units,” adds Mr Callanan.
The concourse includes a first-floor
mezzanine level from where customers will
enter the screens. This floor has been formed
with steelwork supporting precast planks,
which SRS installed along with the steel,
using its on-site 40t-capacity mobile crane.
The mezzanine level culminates with a
7.5m-deep cantilevering concessions box
that sits directly above the main entrance.
The concessions box also features a 3m-long
curved glazed façade, which will offer
cinema goers uninterrupted views across to
Kilkenny city centre.
“The glazed cantilever is the shop
window of the cinema, and signposts the
main entrance to the building,” explains Mr
Dunlop.
Kilkenny cinema is scheduled to be open
in early 2019.
The design is based
around a series of
isolated boxes
