BRITISH STANDARD
The contractor should have a company director responsible for the technical work of the company.
This person is effectively the DI and their duties include control of any temporary works. In very
small companies the same person might also take on the TWC role.
The temporary works is managed either by a TWC, or, more likely, the site would have a trade-based
supervisor handling the day-to-day site temporary works, i.e. performing the TWS role.
5.1.4.3
Projects with more than one contractor
If there is more than one contractor, one should be appointed as the principal contractor (PC); and
it is the PC who takes the responsibility for the site and all the construction on it, whoever carries it
out (see 5.1.1.12). The temporary works should be managed by the PC9s appointed TWC, known as
the PC9s TWC.
Depending on the size or accessibility of the site, the temporary works may be controlled either
directly by the PC9s TWC or by responsible TWSs [see Figure 2b)]. If the site is large, or there is
another site in the local area, then other TWSs could be incorporated into the TW control process.
The arrangement at Figure 2b) is common to many construction sites operating with their own staff.
5.1.4.4
PC with several sites
Small contractors, such as local house builders and many utility companies, operate with multiple
small sites, often with only a few operatives to each site; they should operate in accordance with
their organization9s procedures, including the control of temporary works, even where they are
undertaking routine work.
The PC9s TWC should be appointed by the organization to cover the group of sites, and may be based
in a regional office. The day-to-day control should be left to the responsible TWS on each site.
This procedure, shown at Figure 2c) is common practice with utility organizations and small
building companies.
5.1.4.5
PC appoints a sub-contractor
Where the PC appoints a sub-contractor to provide the labour, and possibly also the equipment to
be used for the temporary works, but retains the management role for the temporary works, the
contractual relationship changes. This is shown in Figure 2d).
The sub-contractor should manage their own work (see the first principle in 5.1.1.10) and should
appoint TWS(s) to assume day-to-day responsibility. The sub-contractor9s TWSs should report to the
PC9s TWC on all temporary works matters.
The management, design and control of the temporary works, along with any other temporary works
on the site, should remain with the PC9s TWC.
