4.4 DESIGN GUIDANCE AND OUTPUT
4.4.7
The following documents provide a source of reference for the British Standard’s (BS’s)
and Euro Norms (EN’s) that are applicable to temporary works systems.
PAS 8812 provides guidance
on
the
application
of
European standards to the
design of temporary works
and aimed at structural and
geotechnical designers of
temporary works, procurers,
local authorities and safety,
quality
and
compliance
managers.
It
aims
to
establish a unified approach
to
design
during
the
construction
process
for
temporary works.
4.4.8
TWf2014:01
provides
general guidance to the
temporary works designer,
and others such as clients,
PD’s and contractors on the
application of EN’s (and BS’s)
to temporary works.
ICE Temporary Works Principles of design and
construction provides an
authoritative
and
comprehensive guidance on
temporary
works
for
practising engineers working
for a contractor or builder, or
a design consultant, or those
intending
to
gain
the
technical elements of skill
needed to perform effectively
in these roles.
To ensure the strength and stability of any temporary works structure, there are three
fundamental aspects that need to be considered. These are:
Foundations
Structural
integrity
Stability
the ability of the ground to carry the loads transmitted
from the temporary works structure without failure or
excessive deformation or settlement
the ability of the temporary works structure itself to carry
and transmit loads to the ground via the foundations
without failure of the structural elements, including fixings
and connections (e.g. by buckling, bending, shear,
tension, torsion) and without excessive deflection
the ability of the temporary works structure to withstand
horizontal or lateral loading without sway, overturning or
sliding failure (stability may be inherent in the temporary
works structure itself or provided by an existing structure,
e.g. the permanent works or a structure being
demolished) there will also be projects where the
temporary condition of the permanent works will require
temporary works to ensure stability.
