be responsible for all the temporary works in the area allocated, irrespective of which organization
carries out the temporary works in the area (see 9.3.2.5).
The principle remains (see third principle in 5.1.1.10) that only one PC9s TWC should be responsible
for a specific area at any one time. The interfaces should be clearly established and a lead PC9s TWC
should be appointed to manage the interfaces between the areas.

It is extremely rare that a building project would justify more than one PC9s TWC.
Responsibilities where a contractor co-ordinates their own temporary works
General
Certain specialist sub-contractors, such as reinforced concrete (RC) frame contractors, ground
workers or demolition contractors, have the experience and competence to organize their temporary
works and have management capability, often including specialist temporary works design facilities;
they can, therefore, be deemed competent to co-ordinate their temporary works.
Where a client appoints a contractor directly, for example an M&E contract, and that contract involves
temporary works, then the temporary works should be controlled and managed.
Both the managing sub-contractor appointed by the PC and the client9s contractor should manage
their own works responsibly. The lines of responsibility are shown in Figure 3. The contractor should
appoint a TWC with a responsibility to the PC9s TWC. They should also co-ordinate their temporary
works with or through the PC9s TWC to ensure no temporary works is affected adversely by any other
temporary works or plant or other adjacent activities. Where necessary the contractors should also
appoint their own temporary works supervisor(s) to manage the day-to-day site activities.
The relationships between the PC and contractor (i.e. a PC appointed sub-contractor or a client
appointed contractor), including the roles of PC9s TWC and TWC are summarized in Figure 4, but the
full details of the relationships, actions and responsibilities are as outlined in Clauses 7, 9 and 11.
