entail, to enable them to carry out their duties in relation to the project recognise their
limitations and take appropriate action in order to prevent harm to those carrying out

the assembly on site of prefabricated elements to form a structure or the
disassembly on site of the prefabricated elements which, immediately before such

Design brief
A document that includes all data and requirements relevant to the design of the
temporary works.
Design certificate
A certificate issued by the designer to indicate that the design is satisfactory and
conforms to the design brief, and, where provided, the design statement.
Design check
An evaluation of the design to determine whether it conforms to the design brief and,
if applicable, design statement, and whether it is adequate to provide a safe
'engineered solution'.
Design check
certificate
A certificate for Category 2 and 3 designs (and potentially required by the organisation
for Category 1 designs) that confirms the design conforms to the design brief, states
the standards/technical literature used; and lists any constraints to loading conditions
imposed. It should be signed by the temporary works design checker and temporary
