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 reuse of temporary works;
n)
environmental information such as the location, altitude and topography of the site, the distance
from the nearest sea (shoreline) or large body of water, distances from the edge of town,
presence of any surrounding structures, tall buildings or terrain causing funnelling of the wind,
rainfall, water levels and current velocities;
o)
any requirements for cladding the temporary works with debris netting, signboards or
impervious sheeting;
p)
site investigation data and reports relating to the areas under and adjacent to the foundations of
the temporary works or proposed excavations, including information on all underground and
over‑head services;
q)
specific requirements, including any limitations on the staged construction of the works due to
positioning of construction joints, sequence of separate pours, rate of successive pours, timing of
post‑tensioning and removal of supports;
r)
any requirements for pre‑cambering or residual camber;
s)
loads that might be induced in the temporary works by permanent works that have been
completed, such as the application of staged post‑tensioning, load redistribution and any
movements of significance, including any settlements or deflections that can be anticipated from
the permanent works as load is progressively increased;
t)
any limitations stated by the PWD on the position and extent of loads imposed by the temporary
works onto elements of the permanent works which have been constructed; for example, loads
imposed by successive floors of multi‑storey construction onto lower floors or loading of
permanent foundations required to support the temporary works, or lateral loads on columns
from top restrained falsework;
u)
any limitations on the positioning of loads from temporary works over underground services or
voids, adjacent to excavations or retaining walls forming part of the permanent works;
v)
proposals for the protection of the temporary works, including its foundations, against
disturbance or impact;
w) limitations imposed by various authorities in relation to working within or adjacent to railways,
highways, watercourses, etc.;
x)
any environmental constraints placed on the site by the local authority or other body, for
example, a requirement by the local authority to limit noise to certain hours of the day;
y)
details of obstructions that might preclude or influence the position of the temporary works;
z)
requirements for design deliverables from the TWD and the format of the design output; and
aa) proposed level of design check category.
NOTE 2 The information required might need to be obtained from various sources, and might include data from
earlier site operations or details of existing structures. Certain information might be of direct relevance to both the
permanent works designer and the temporary works designer, such as site investigation information or where the
temporary works affects or takes support from the permanent works.
12.2.5
The TWD should be provided with a design brief, irrespective of whether they are from the
construction organization or not.
NOTE Some of the required information might only be available from other designers. Attention is drawn to the
responsibility of designers under the CDM Regulations 2015 [3] to cooperate with the PD and any other designer.
