BIG FOOT SYSTEMS SUPPLIES SUPPORT FOR
ACOUSTIC SCREENING - HATTON WALL, LONDON
Big Foot Systems has supplied custom support for acoustic
screening on the rooftop of a development of luxury flats,
offices and retail outlets at Hatton Wall in Holborn, London.
The acoustic screening surrounds a group of condensers and
plant on a PVC membrane and green roof which effectively
blocks plant noise from the surrounding private homes.
Big Foot’s technical team designed a system which would
support the heavy acoustic screening using supports which
were designed to ensure the pressure exerted by their feet
did not exceed the limit of the lightweight roof. Calculations
established the size of frame required and the number and
size of foot bases in contact with the roof needed to ensure
the cumulative weight was dispersed evenly over the roof area
and was within workable loads of the roof build up. Dynamic
forces were also taken into account as the structure had to
withstand the high winds created due to funnelling by the
surrounding buildings. The framework installed was therefore
wider than the screens they supported, affording a greater
degree of protection against ‘tipping’. Big Foot’s customised
system proved the ideal solution, offering project specific non-
penetrative support.
“The normal ways of fixing screens to our supports had to be
modified to allow the panels to fit. Normally, we would hang
panels from our posts or A-frames but the weight and space
meant that this wouldn’t have worked” explained Ashley
Simmans, Big Foot Systems Site Engineer. “We designed and
tested a new set of bracketry alongside contractor Bespoke
Acoustic Solutions to allow the panels to sit on top of our
supports which worked well. Installation was completed within
a matter of days.”
