13.1.5
13.2
BRITISH STANDARD
A designer includes anyone who specifies a design, design standard or design method, alters a design,
or specifies a particular method of work or material, or arranges for or instructs someone else to do
so. The designer should justify their requirements by identifying the associated risks and how they
might be mitigated.
Design brief
13.2.1
A design brief should be prepared to serve as the basis for subsequent decisions, design work,
calculations, drawings and design checks. All concerned with the construction should contribute
towards the preparation of the brief.
13.2.2
The brief should include all data relevant to the design of the temporary works including residual
risks introduced by the methodology chosen by the site team or by the PWD. It should be prepared
early enough to allow sufficient time for all subsequent activities, i.e. design, design check,
procurement of equipment and construction/erection of the scheme.
13.2.3
The preparation of the brief might involve relatively little work for the smaller scheme, but for major
work such as the construction of a large bridge or deep excavation a large amount of information
might be needed; the TWC should ensure that sufficient and comprehensive information is collated
before design work can commence or a programme for the construction of the temporary works can
be drawn up (see Annex G).
13.2.4
The following information should be taken into account for inclusion in the preparation of the brief:
a)
details of the organizations involved in the design of the scheme and their respective
responsibilities, including the name and contact details of the PC9s TWC, the TWC or both as
appropriate;
b)
appropriate details of the permanent works in an agreed format;
c)
appropriate clauses from the specification for the permanent works;
d)
statement of any requirement to design the temporary works in accordance with a particular
standard or guidance document;
NOTE 1 For example, in the case of falsework, whether the design method is to be in accordance with
Section 3 of this British Standard or BS EN 12812.
e)
information on any significant residual risk associated with the design of the permanent works;
f)
programme for the construction of the permanent works;
g)
programme for the various phases of the design, design check, any external approvals,
procurement and erection of the temporary works;
h)
the timing for the removal of the temporary works in relation to the ability of the permanent
works to be self-supporting;
i)
any requirements for access onto, under, or around the permanent works or temporary works;
j)
requirements for access for erection, maintenance, use and dismantling of the temporary works
and for other site activities;
k)
any requirements for public access, for example a requirement to keep a public footpath open;
l)
equipment and materials available for use in the temporary works;
m) proposals for any moving and re-use of temporary works;
n)
environmental information such as the location, altitude and topography of the site, the distance
from the nearest sea, rainfall, water levels and current velocities;
