9. Erection
i) Holes for straight posts will not be less than 450mm square and holes for struts not
less than 450mm long by 300mm wide. They will have vertical sides.
ii) The holes for staining posts will be filled up to a minimum of half their depth with
concrete. The concrete will be well rammed as filling proceeds. Before the
concrete has hardened the remainder of the hole will be filled with earth and well
rammed as the filling proceeds.
iii) Holes for intermediate posts will have vertical sides and be of sufficient size to
allow a 75mm surround of concrete. The concrete to be placed as for straining
posts.
iv) Straining posts will be provided at all ends and corners, at acute changes in level
and at intervals on the straight. Struts will be fitted to straightening posts in the
direction of each line of fence.
v) Line wires will be attached to intermediate posts by means of "hair pin" staples.
vi) Chain link mesh will be strained between each pair of straining posts by means of
stretcher bars and then attached to the line wires by wire ties 150mm apart on
