8.2
BRITISH STANDARD
Designers' DI
8.2.1
Organizations carrying out permanent and/or temporary works designs should have a DI to ensure
that a procedure suitable to their organization is in place and managed.
8.2.2
The designers' DI should establish a procedure describing how the main items for which the designer
has responsibility should be managed. The main recommendations to be addressed, in addition to
those in 8.1, are as follows.
8.3
8.3.1
a)
Procedures should be appropriate to the type and complexity of work, and associated risks,
which the designer is to consider.
b)
Sub-consultants should have adequate procedures for managing the temporary works design.
c)
Any temporary works design commissioned by a PC or other organization should be initiated
with a design brief, from the PC9s TWC or TWC. The designer should prepare a design statement
or approval in principle (AIP) or equivalent where so required.
d)
Any temporary works design checker commissioned by a PC or other organization should be
provided with the design brief, design statement or AIP or equivalent where prepared and the
necessary drawings and other documents [as noted in 8.1.4c) but not calculations] before the
design check is undertaken.
e)
The designer should respond promptly and clearly to any request from the PC or a contractor,
appointed to manage part of the temporary works, for information or design criteria, in respect
of temporary works, to allow the TWD to complete the design and allow the PC or other
contractor to manage and discharge their responsibilities.
f)
The designer should liaise fully and clearly with all parties, initially with the TWC, but this may
be extended to cover other designers and/or design checkers.
Permanent works designers
Permanent works designers should address the buildability of the permanent works and identify,
and make provision for, any temporary works and temporary conditions required by their design and
their assumed method of construction. This should include:
a)
a proposed method and sequence of construction which should have no adverse effects on the
permanent works;
b)
deciding on and communicating the intended construction process, giving particular attention to
new or unfamiliar processes;
c)
considering the stability of existing structures and partially constructed/erected/ demolished
structures and, where this is not immediately obvious, providing information to show how
temporary stability could be achieved;
d)
identifying where standard industry details are not suitable, and where detailed structural
design is to be carried out by others;
e)
considering the effect of the proposed work on the integrity of adjacent/existing structures,
particularly during refurbishment;
f)
ensuring that the overall design takes account of temporary works which might be needed, no
matter who is to develop those works;
g)
ensuring that consideration has been given to the availability of sufficient space required to
construct or maintain the structure; and
h)
clearly stating loads for which the structure has been designed including the proposed plant
installation loads and plant routes.
