10.2.2.7
If the PC’s 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
PC’s TWC considers that they are under undue pressure to achieve production at the expense of
structural stability, they should seek assistance from their DI (see 8.2.3).
10.2.2.8
The PC’s TWC should raise with the DI any matters of concern that cannot be adequately resolved at
site level.
10.2.2.9
The PC’s TWC should verify that adequate checks have been completed to confirm the proposed
temporary works have no adverse effect on the permanent works. This should be either by a certificate
signed by the TWD and TWDC or by a statement that the temporary works design is in accordance with
the PWD’s sequence/methodology or by confirmation from the PWD that the proposed temporary
works have no adverse effects on the permanent works.
10.2.2.10
The PC’s TWC should have full authority to carry out their tasks including authority to stop the work
if it is not being carried out satisfactorily. The PC’s TWC should be responsible for the provision of
formal permission to load or progress beyond the hold point. The PC’s TWC should only permit work
to continue beyond any critical stage when it is to the standard specified.
10.2.2.11
The role of the PC’s TWC should not include a responsibility for carrying out any design or design
checking 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.
10.2.2.12
10.2.3
The appointment of a person as PC’s TWC should not preclude them from carrying out design and/or
design checking if they are considered competent and it is within their experience based on the
complexity of the project (see 4.2.1, 7.4.1 and Table 2).
Duties of the PC’s TWC
The PC’s TWC should:
a)
coordinate all temporary works activities;
b)
confirm that a temporary works register is established and maintained (see 5.2);
c)
confirm that information relevant to the temporary works has been received from the client,
principal designer and permanent works designer, as appropriate;
d)
confirm that a design brief is prepared (see 12.2) with consultation within the project team and
that it is both adequate and in accordance with the actual situation on site;
e)
confirm that any other temporary works in the vicinity are referenced in the design brief;
f)
confirm that any residual risks identified at the design stage, assumed methods of construction
or loading constraints identified by the PWD are included in the design brief;
g)
confirm that all temporary works designers and design checkers have been assessed as
competent to carry out designs and design checks;
h)
confirm that the design brief is issued to the TWD and that a satisfactory design is carried out;
i)
confirm that a design check is carried out by someone who was not involved in the original
design (see 12.7);
j)
where appropriate, confirm that information on the certified temporary works design is made
available to other interested parties, e.g. the principal designer and/or the designer of the
permanent works, and, where required, to the client;
k)
register or record the drawings, calculations and other relevant documents relating to the final
design;
