9 Contractors9 procedures
9.1
9.1.1
Organizational interfaces
The design and construction of permanent works and the attendant temporary works often involves
several organizations, therefore introducing a number of organizational interfaces. Common
arrangements include the following and combinations thereof:
a)
equipment can be hired, with the supplier carrying out the design, or supplying the basic
design data;
b)
equipment can be erected using operatives who are not direct employees of the main
construction organization, e.g. the supplier of the equipment might also erect it; and
c)
use of a design produced by another organization.
9.1.2
When work is being carried out by different organizations, the organizational interfaces can be
manifested on site as physical interfaces between different phases of the scheme, e.g. it is common
for one organization to prepare and provide the foundations upon which another subsequently erects
the main temporary works structure. The physical interface in this example is particularly critical, but
in all cases the physical constraints and interface conditions should be clearly defined and the work
procedures adopted should take account of these interfaces.
9.1.3
The TWC should manage these interfaces and retain an overview of the whole scheme to ensure each
step of the procedure is completed and does not adversely affect the scheme.
9.1.4
Details of the interfaces should be included in the construction phase plan.
9.1.5
When work is being carried out at a number of small sites, a TWS with an appropriate level of
authority may be appointed for each individual site, under the overall responsibility of a single TWC.
9.1.6
Contractors are appointed by clients, or by other contractors to carry out the works. Where there
is more than one contractor appointed by the client, one contractor should be appointed PC. In all
cases the contracting organization9s procedures should recognize that, whatever the method of
procurement, the PC has ultimate responsibility for the safe execution of all temporary works on site.
9.1.7
The contractor9s procedure should cover the management of any temporary works and include
measures for ensuring that the roles of a TWC and TWS are carried out by competent individuals.
