Maintenance and inspection of listed buildings with a moat from a ladder
on a pontoon are no longer possible, as a consequence of stricter rules
from the Health and Safety at Work Inspectorate. The Government Buildings
Agency has therefore been forced to look for other possibilities.
Possibilities which do be in force for regular returning conditions
also. In order to avoid a prejudiced approach, the problem to be investigated
has been split into three study areas: the workplace, reaching the
required height and support on the ground.
A range of workplaces are possible, but under these conditions, several
can be immediately excluded, as banned by the Health and Safety at Work
Inspectorate. These include standing on a ladder or working suspended in a
safety harness. Work in a suspended work bin is also not permitted. Work
on a scaffolding or on a raised workplatform is permitted. The preferred
choice of workplace depends on the duration of the work and the
possibilities for installing the chosen system.
In order to reach the specified height of 20 metres, use of a ladder is
not permitted. Scaffolding is less flexible, but on the basis of price
differentiation and depending on the frequency of use, it may still be the
best solution. However, the most flexible and compact solution is the
The final study component focuses on the system of supporting the device,
either on the ground or on a floating construction. It turns out to be
possible to create a floating construction, but for reasons of stability
and simplicity, a combination of direct support and floating emerges as
the most obvious choice.
By combining the solutions from these sub-problems, multiple possibilities
emerge. However, the type of work and the planned investment will
determine the preferred option, which will then be further elaborated.
