BS 5975‑1:2024
The designer should select the format of the design output, including the language, the units (for
specified anchorages, etc.), type of electronic or hardcopy drawings and any BIM material, all with
particular regard to the accessibility of the format for the end user(s). The design output should also
define the requirements for foundations (including simple tests to confirm bearing stratum capacity
or soil type), positions of components, the details of connections to other components, limitations for
loading and sequence of operations and anything else considered necessary.
NOTE 1 The designer’s calculations do not form part of the design output.
NOTE 2 Attention is drawn to the CDM Regulations 2015 [3], which require that any designer provides adequate
information about any residual risk associated with the design. There is also a requirement to coordinate the work
with that of others in order to improve the way in which risks are managed and controlled. This might include the
use of suggested construction sequences.
12.6.3
For complex schemes the temporary works designer should brief the site team on the key elements
and hazards identified during the design process.
12.6.4
Any British Standards or other design guidance, or software, used in the design should be
summarized separately from the design calculations and communicated to the TWDC.
NOTE For complex schemes the information may be presented in the form of a “design statement”, which may also
include: an idealized structure, method(s) of analysis, and the version of computer software, if any, used.
12.7 Design check
12.7.1
Prior to the commencement of the construction work, the proposed temporary works design should
be checked for concept, adequacy, correctness and conformity to the requirements of the design brief.
This check should be carried out by a competent person(s), independent from those responsible for
the design. The competence of the TWDC and their remoteness or independence from the TWD
should be greater where new ideas are incorporated or the temporary works are complex.
12.7.2
When the design has been completed, or is advanced to an appropriate stage, the design brief should
be provided to the organization/individual who is to carry out the design check, together with the
relevant design statement, drawings and specification, and associated information. The responsibility
for stating the independence of the design check category should be established at an early stage as
the category can affect the complexity and volume of design output. It should require input/advice
from the designer. The check category is unlikely to be known at the time of writing the original
register, but should be included when determined.
12.7.3
The following design checks should be undertaken for the categories given in Table 2.
NOTE The categories relate to the level of independence of the design check and are not related to the
classification of risk associated with implementation given in 5.1.3 and Table 1.
a)
For Category 0, the check should include verification that the application selected suits the limits
and conditions. The independence of the check should be established by the person selecting the
standard solution obtaining approval from a second competent member of either the site or
design team. The degree of formality should be determined by the organization.
b)
For Category 1, the check should include verification both that the simple design suits the site
conditions and that relevant technical information has been interpreted correctly. Approval
should be obtained from a competent member of the design team. The degree of formality
should be determined by the organization.
c)
For Category 2 and Category 3, the checker should carry out the check without reference to the
designer’s calculations, using only the design brief, including its associated information, and the
design output.
