Heritage Roof Works -
The first package won by McNealy
Brown as part of the St Pancras Station
Refurbishment included the Heritage
walkways to the main Barlow Shed
Roof.
The package consisted of three main
elements, being the Lateral Walkways
each approx 197 linear metres to each
side of the building, the Radial Access
Walkways following the roof line at
each gable end of the building, and
Parapet Handrails at the main roof
eaves, again running the length of the
building and resin fixed through
existing stone copers - all polyester
powder coated finish.
All details closely copied the original
‘Barlow’ design, the lateral walkways
being mounted on cast aluminium
brackets incorporating various
tolerance to combat roof movement
from its’ initial build.
All walkways were fitted with a
proprietary tested & commissioned
‘Mansafe’ system.
The walkway infills and stair
treads were galvanised open
steel flooring and the
balustrades designed to suit a
horizontal loading of
0.36kN/lin.m.
The walkway posts were
spaced to suit the main roof
trusses and incorporated
clamped handrail and
fabricated balustrade panels
housing ornamental feature
castings replicated from the
original design, this requiring
further weld testing and
certification for dissimilar
metals.
At the north end and to each
side are the main access
towers to the roof where
walkway platforms were built
around the towers and
included a retractable
extending walkway with
lockable gates extending over
the end of the building to
access the maintenance gantry
over the new transition roof.
