manufacturer’s instructions. Where loads are increased or hop-ups are used, additional
bracing is required. Each proprietary system varies with manufacturer and system, and
the manufacturer’s instructions must be carefully followed to ensure that the scaffold is
erected safely.
To aid the flow of work, ‘hop-up’ scaffolding units can be used to increase the height
that the workforce can access at each lift (Figure 2.5 and Photograph 2.8). These can be
used between the standards or can be used between the internal standard and wall, providing
a platform that is closer to the area of work and not reducing the width of the standard
platform.
Proprietary scaffolds have the benefit of rapid erection and disassembly; however, their
use is limited to relatively standard operations due to the size of the components. Where
loads are known to be considerable and the scaffolding arrangement is complicated due to
specific project layout/geometry, then traditional scaffolding designed by a structural engineer
may provide a more flexible and appropriate solution.
Lateral stability – tying into the building
Independent, putlog and proprietary scaffold systems must be tied into stable parts of the
building structure to ensure that the scaffolding remains stable. Ties must not be linked to
