The designer should liaise with the PD to provide all necessary information relevant to any temporary
works or temporary condition(s) to the PC through the PD.
Temporary works designers
General
8.4.1.1
TWDs and TWDCs (temporary works design checkers) should confirm that the design details
and outline methodologies are accurately translated into the design output, and that the design
follows appropriate engineering principles. This includes any assumed construction methods,
sequences, temporary works requirements, and loads to be either imposed on or supported by the
permanent works.
8.4.1.2
TWDs and TWDCs should confirm that the design output adequately describes the design in a design
check certificate or other suitable form of record (see 13.7.5).
8.4.1.3
8.4.2
Where the category of design check is not specified by the contractors' procedures or the client, the
TWD, in consultation with the TWC, should advise the minimum category of design check (see 13.7).
Lead designers (in relation to temporary works design)
8.4.2.1
Where a temporary works scheme involves design contributions from more than one designer, one of
the designers should undertake the role of lead designer, and manage the design interfaces. The name
of the nominated lead designer should be recorded. The lead designer for a temporary works scheme
might not necessarily be the principal designer. On completion of the design, a single design certificate
should be issued (see 13.7.5).
8.4.2.2
The lead designer should ensure that:
8.4.2.3
8.5
a)
there is a distribution of design tasks amongst appropriate designers, especially where the
design of temporary works is an integral part of the permanent works methodology;
b)
the communication of design data between organizations is controlled and any iterations are
completed to the required levels;
c)
design contributions from all designers are compatible with each other;
d)
they have a holistic understanding of the whole design;
e)
the design output is complete and clearly communicated; and
f)
the principal designer and TWC are informed about significant residual risks associated
with the design.
The same approach, as outlined in 8.4.2.1 and 8.4.2.2, should be taken where the check of a temporary
works scheme involves contributions from more than one design checker.
Principal designers
In relation to temporary works, the PD should ensure that:
a)
b)
there is a coherent construction method which identifies all key temporary conditions and
temporary works;
the finally agreed construction method, sequence and temporary works are not deleterious to
the permanent works design;
