This
project typifies a temporary propping and shoring requirement
for a building refurbishment. The client's specification was
to provide temporary support to a wall that required to be
removed at ground floor level only.
The load bearing wall in question supported the buildings
roof, 1 floor level and at 350mm thick, a large self weight.
The structural engineer involved advised that due to uncertainties
in the quality of the material below ground floor level, the
temporary support would need to be designed to transmit vertical
and lateral loads down to ground level without exceeding the
specified maximum ground bearing pressure.
Pictures taken during initial survey of building.
Scaffolding
was erected both sides of the wall. Then four 'core drilled'
holes were drilled through the wall to allow insertion of
four I-Section beams, which would provide support during demolition.
Following scaffold inspection, the wall was removed at ground
level.
The
permanent steel structure was then installed, which enabled
the scaffolding to be removed.
