13.1.2
The PC’s TWC or TWC should verify 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. The implementation plan should include
definition of the regular inspections which are required during the lifetime of the temporary works.
13.1.3
The implementation plan should be developed taking into account the site conditions, programme,
original design brief and the construction phase plan, and using the drawings, specification and
methodology supplied by the designer.
13.1.4
The implementation plan should define hold points at which the structure is to be checked for
conformity and who is authorized to do so, including issuing permits to load or unload (release the
hold point), signing of checklists, etc., by the PC’s TWC, the TWC or the TWS, and how the results of
these inspections are to 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 according to the terms of the individual’s
appointment.
13.1.5
The PC’s TWC or TWC should verify that the guidance on the implementation of the design provided
by the designer or supplier, including any relating to residual risks [see 7.1.4c) and 12.6], is
incorporated into the implementation plan. The design residual risks should be addressed in the
method statement.
13.1.6
The design documentation and method statement should be followed but those responsible for work
on site should compare conditions experienced on site during construction with those assumed by
the design and take appropriate action if it becomes apparent that they are different.
13.1.7
At all stages during fabrication/pre‑fabrication, construction/erection, use and dismantling of the
temporary works, the information being used should be checked to verify that it is correct, and that
the work carried out is in accordance with the design details (drawings/sketches) and is as specified.
NOTE 1 This is necessary to confirm that the completed structure will function as intended and to establish that
the temporary works are safe to use, but also to facilitate remedial work if this proves necessary; it is often difficult
to do this later.
NOTE 2 Details of checking procedures for falsework are given in BS 5975-2:2024, Clause 12.
13.1.8
Prior to bringing temporary works into service, a final inspection should be carried out to verify that it
has been constructed in accordance with the requirements of the design and any subsequent approved
modifications. The results of these inspections, together with any requirements for improvement,
should be recorded by the person identified in the implementation plan. For complex or innovative
designs, a decision should be taken as to whether an inspection is to be carried out by the TWD.
NOTE It might be necessary to carry out inspections of the temporary works at points during assembly/erection.
13.2 Loading and unloading temporary works
13.2.1
13.2.1.1
Loading (bringing into use)
As a means of exercising control over bringing the temporary works into use, a formal procedure for
giving permission to load or proceed to the next stage in the implementation sequence should be part
of the implementation plan.
NOTE In simple cases a single “permit to load”, when the temporary works has been checked, might be appropriate.
In complex or larger cases, permits might be required at different stages, both as regards loading or for different areas
or for excavation. It is normally desirable to limit the period of validity of the permit, as subsequent modifications or
changes in circumstances (e.g. soil wash-out under footings) can occur; for example, a permit to load for a falsework is
normally valid for 24 hours. The area over which loading can take place, and to what extent, is set down in the permit,
e.g. it might be “reinforcement only”.
