provided by the supplier or organization responsible for the standard solution.
14 Site considerations
14.1
Co-ordination, supervision and checking of work on site
14.1.1
Work on site should be the subject of careful direction, supervision and inspection and checks to
ensure that the temporary works is constructed safely in accordance with the design and specified
materials and equipment, and that only when all checks have proved satisfactory is the works loaded,
used, maintained, unloaded and then dismantled in accordance with an implementation plan.
14.1.2
The PC's TWC or TWC should ensure that a temporary works implementation plan is in place
covering the erection/assembly, use, unloading and dismantling of the temporary works including
what inspections, checks, hold points, permits and certification are required. This should include
defining the regular inspections which are required during the use (loading) of the temporary works.
NOTE 1 The implementation plan could consist of the method statement, task specific risk assessment, inspection
and test plan (ITP), checklists and other certification (for example, quality control check lists).
NOTE 2 The inspection and test plan can be used to define hold points, where works stops for an inspection or
testing to take place. A permit is used to release the hold point and allow work to continue.
14.1.3
14.1.4
The implementation plan should be developed taking into account the site conditions, programme,
original design brief and the construction phase plan and use of the drawings, specification and
methodology supplied by the designer.
The plan should define hold points at which the structure should be checked for conformity and who
is authorized to do so, including issuing permits to load or unload (release the hold point), signing
of quality control check lists etc. by the PC's TWC, the TWC or the TWS, and how the results of these
inspections should be communicated and acted upon. If the implementation plan has been produced
by others it should be approved by the PC's TWC or TWC.
NOTE A TWS may issue the permit for a defined scope and range of work as described in the individual's
appointment.
14.1.5
The PC's TWC or TWC should ensure that the guidance on the implementation of the design provided
by the designer or supplier, including any residual risks [see 8.1.4c) and 13.6], are incorporated into
the implementation plan. The design residual risks should be addressed in the method statement.
14.1.6
The design documentation and method statement should be followed but those responsible for work
on site should bear in mind the need to compare conditions experienced on site during construction
with those assumed by the design in order that appropriate action can be taken if it becomes
apparent that they are different.
14.1.7
At all stages during fabrication/pre-fabrication, construction/erection, use and dismantling of the
temporary works, the information being used should be checked to ensure that it is correct, and that
the work carried out is in accordance with the design details (drawings/sketches) and is as specified
to ensure that the completed structure will function as intended. This is necessary, not only to ensure
that the temporary works are safe to use, but also to facilitate remedial work should this prove
necessary; it is often difficult to do this later.
NOTE
Details of checking procedures for falsework are given in 20.4.
