managing temporary works.
Control of risk
COMMENTARY ON 6.1.3
This clause relates to implementation risk and is not to be confused with the category of design check as
outlined in 13.7 and specifically Table 2, for example, the implementation risk for the same temporary
works structure erected in two different locations can vary significantly depending on proximity to
local assets, such as an adjacent railway line, thus justifying different levels of risk, and changing the
risk classification 3 in contrast the temporary works design might be unchanged requiring the same
category of independent design check.
6.1.3.1
The risks associated with temporary works can be considered to arise from their design, their
construction and use, and the consequences of their failure. Risks associated with design relate to the
complexity of the design. Mitigation of design risk is addressed through the selection of the category
of design check (see 13.7). Risks associated with the construction, use and removal of the temporary
works relate to such aspects as workmanship, materials, experience and manner of use. These are
termed execution risks. Risks associated with the consequence of failure of the temporary works come
from the location of the temporary works, and what might be affected by the failure. Execution risk
and consequence of failure risk combine to form an implementation risk.
6.1.3.2
To assess the risks associated with temporary works on a project, each item of temporary works
should be classified and appropriate procedures adopted to control the risks. The classifications used
should be
