31st Oct 01
Excavate the foundation (refer to Figure 2-6).
WARNING
Do not place excavated earth within 1 m of the excavation
edge.
Erect the concrete shuttering to produce the required base.
Position the cable ducts (if low level cable entry method is in use). Ensure
that they are positioned so that they face towards the cabinet entry point.
Make the foundation from 20 mm mix concrete with the cable ducts (If
used) mounted in position. If required, locally thicken the areas around the
foundation bolts.
CAUTION
Ensure the concrete is laid to give a water run off with
tapered edges. Where a field site, other than an already
permanent hard standing, is laid, the foundation must
have a bevelled finish.
To avoid over stressing the cabinet, use a spirit level or
theodolite to check that the concrete plinth surface is level
to 3 mm across diagonals.
