High speed Hi-Point dramatically cuts installation time
High speed Hi-Point
dramatically cuts
installation time
The roof installation programme for a multi-storey luxury
apartment block in Liverpool was dramatically cut to just
two days, thanks to the use of the new Hi-Point roofing
system from Kalzip.
At 27 storeys the residential development, which is part of the
mixed use Unity Project, presented numerous challenges, not
least because of its location in the heart of the city centre.
Owing to the scale of the project; speed of installation,
increased safety and reduced man-hours working at height,
were prime considerations for designers Dane Architectural
and main contractors Laing O’Rourke. The striking 1.5 degree
pitched Hi-Point gull wing roof, which sits 94 metres above the
ground, proved to be the ideal solution.
The full 22 modules, which were precision manufactured and
assembled by Kalzip under factory controlled conditions, were
lifted and bolted into position in just two days allowing
significant reductions to be made in both the roof installation
programme and the overall site time.
The frames for the roof sections were constructed from cold
rolled channel sections produced by Kalzip Construction and
Engineering Products, and, as whole life performance and
durability were also important factors in the specification of the
roof, the Hi-Point system was equipped with a fully insulated,
built up Kalzip system. Incorporating steel liner panels from
Kalzip Panels and Profiles the system was topped with 1.2 mm
clad stucco embossed Kalzip 400 aluminium standing seam
sheets. A range of Kalzip fabrications including verge and roof
flashings, mono ridge and verge capping details, were also
specified in a stainless steel finish to complement the wall
panels, all of which were manufactured by the Kalzip
Fabrication department.
The 398 square metre Kalzip standing seam roof also features
a 25 metre long thermoplastic polyolefin (TPO) walkable
insulated membrane gutter, produced in two modules for
connection on site. Fully recyclable, the TPO gutters are also
environmentally friendly and produce no harmful gas emissions
during the manufacture or the hot-air welding process.
