11.3.2
BRITISH STANDARD
Role of the TWC
11.3.2.1
The TWC should be the single point of contact for providing and receiving relevant information from
the PC9s TWC and the contractor9s site team for their organization's temporary works matters.
11.3.2.2
The TWC should be responsible for the implementation of the contractor9s approved procedure for the
control of temporary works.
11.3.2.3
The role of the 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.
11.3.2.4
The appointment of a person as a 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 5.2.1, 8.4.1 and Table 2).
11.3.2.5
When appointed, the TWC should co-ordinate the contracting organization's temporary works on site,
liaising with the PC's TWC and any PC's TWS (see 11.3.3) including the preparation of design briefs,
provision of information regarding any proposed TW designers and design checkers, inspection of
temporary works on site, provision of any design and design check certificates to the PC's TWC and
checking the erected temporary works on site before loading/unloading.
11.3.2.6
The TWC should be responsible to both their organization9s designated individual, for the
implementation of their organization's procedure, and the PC9s TWC (see 11.2) for ensuring that their
temporary works is managed and designed in accordance with the relevant procedures, drawings and
the specification.
NOTE
The PC's TWC remains ultimately responsible for the temporary works on the project/site.
11.3.2.7
The TWC should not be responsible for the day-to-day progress of the temporary works or other
project matters (e.g. commercial or programme matters). Where this is not possible, the PC's TWC
should recognize that the role of TWC overrides other responsibilities the individual might have
and should not put progress of the works above the safety of the temporary works. However, it is
recognized that this might not be possible on projects that have few or no engineering staff.
11.3.2.8
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, then they should seek assistance from the organization9s designated individual
and/or the PC9s TWC.
11.3.2.9
On larger sites the TWC may request that one or more temporary works supervisors (TWSs) be
appointed to supervise their specific temporary works (see Clause 12).
11.3.3
