11 Temporary works supervisor
11.1 General
The TWS should be aware that the PC’s DI defines the PC’s TWC lines of responsibility in relation to each
contractor’s TWC and/or TWS employed on that site, using Figure 2 and Figure 3 for guidance (see 4.1).
11.2 Role of the TWS
11.2.1
The TWS, where appointed, should be responsible to the PC’s TWC or TWC as appropriate. The TWS
should assist the PC’s TWC or TWC, as appropriate, in the supervision and checking of the temporary
works. The line of responsibility should be appropriate to the organization making the appointment
and whether the organization is approved to manage their own temporary works.
11.2.2
A TWS should only be authorized to issue a permit to proceed, e.g. load (bring into use) or unload
(take out of use), if the DI of their organization and the PC’s TWC are satisfied that:
a)
an individual TWS is competent and has been given the appropriate authority; and
b)
the risk classification (see 5.1.3 and Table 1) identified is low or very low.
