10.3.2.8
If the TWC has responsibility for both checking the temporary works and progress of the construction
works, decisions should not be compromised by commercial or other pressures. If the TWC considers
that they are under undue pressure from site management to achieve production at the expense of
structural stability, they should seek assistance from the organization’s DI and/or the PC’s TWC.
10.3.2.9
On large or complex sites the TWC should request that one or more temporary works supervisors (TWSs)
be appointed where assistance is required in the supervision of temporary works (see Clause 11).
