The PC9s TWC should control the other temporary works on the site, and liaise with other contractors,
to control the various interfaces.
NOTE For example, a RC frame contractor would not necessarily be aware that a ground work sub-contractor
was digging a trench across the site close to the RC frame construction.
5.1.5.3
Client-appointed contractor
Where a client appoints a contractor directly and where the work has a temporary works element,
such as installing M&E equipment, the implications for the site and the PC can be significant and the
effect on procedures should be considered to ensure the PC9s TWC can discharge their responsibility
in relation to temporary works (see 7.1.3).
The PC9s DI should confirm that the contractor9s procedure for the control of temporary works is
satisfactory and the client9s contractor should appoint a TWC to control their temporary works [see
Figure 3b)].
The TWC should report to the PC9s TWC and provide a method of communication to liaise between
the site and the other contractors for temporary works.
As there is no contract between the parties involved in the temporary works (see Figure 1), the
client should take into account that any such appointed contractor should be made aware of the
implications and the continuing role of the PC9s TWC on the project. This should be made clear to any
contractor appointed by the client at an early stage in the procurement/management process.
5.2
Training
COMMENTARY ON 5.2
Competence assumes a sufficient up-to-date knowledge of temporary works relevant to the complexity of
the project. Although it is desirable that temporary works is included in college and university courses,
detailed practical knowledge of the subject is gained through practice. This knowledge is gained by
observation, by CPD, or by experience, supplemented by regular training.
It is desirable that universities and colleges include temporary works within the syllabus for building,
construction and civil engineering courses.
Although detailed technical knowledge on temporary works has historically been considered necessary
for contracting staff, the experience and understanding of the effect of temporary works on design and
construction leads to a broader based understanding and a more informed student. This promotes
better design of permanent works and better informed engineers joining the construction industry.
A syllabus would be expected to include an introduction to the types of temporary works, both above and
below ground; an understanding of likely management processes to be adopted to control the temporary
works, with, where possible, indications of the cost implications of temporary works. Temporary works
involves assessment of risk, and it is expected that risk management would already be included in
the syllabus.
In addition to a general awareness of temporary works, the more commonly occurring temporary works
of trenches, scaffolding, backpropping, crane pad foundations, hoardings etc. might justify more detailed
coverage on most courses. It is desirable that the principles of stability of temporary works structures
are included in this syllabus.
It is also desirable that non-technical courses at colleges and universities for subjects such as quantity
surveying, building management etc. include awareness in temporary works. This significantly improves
the recognition of temporary works as an important element in construction, contributing to safer, more
economical construction.
