12 Temporary works supervisor
12.1
General
The TWS should be aware that the PC9s DI defines the PC9s TWC lines of responsibility in relation to
each contractor9s TWC and/or TWS, which is employed on the site, using Figure 2 and Figure 3 for
guidance (see 5.1).
12.2
12.2.1
Role of the TWS
The TWS, where appointed, should be responsible to the PC9s TWC or TWC as appropriate. The
TWS should assist the PC9s TWC or TWC, as appropriate, in the supervision and checking of the
temporary works.
NOTE The line of responsibility is appropriate to the organization making the appointment and whether the
organization is approved to manage their own temporary works.
12.2.2
12.2.3
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 PC9s TWC are satisfied that:
a)
an individual TWS is competent and has been given the appropriate authority in respect of that
individual; and
b)
the risk classification (see 6.1.3 and Table 1) identified is low or very low.
The role of the TWS is to provide on-site support to the PC9s TWC or TWC for the control of temporary
works; as such the TWS should not be responsible for any design or design checking of temporary
works but should be responsible for the implementation of the PC9s or contractor9s procedure for the
control of temporary works.
NOTE This exclusion also covers the determination of specific loads; assessment of load paths; engineering checks
of any kind; determination of foundation capacity, etc.
12.2.4
The appointment of a person as TWS should not preclude them from carrying out design or design
checking if they are considered competent (see 5.2.1, 8.4.1 and Table 2).
