subject to the approval of the Engineer.
Wire crates built in-situ, shall not be larger than 7.50 meter x 3 meter x
0.60 meter, nor smaller than 2 meter x 1 meter x 0.30 meter. Sides of
large crates shall be securely stayed at intervals of not more than 1.50
meter to prevent bulging.
The netting shall be made by fixing a row of spikes on a beam at a
spacing equal to the mesh. The beam must be a little longer than the
width of neeting required. The wire is to be cut to lengths about three
times the length of the net required.
Each piece is bent at the middle round one of the spikes and the
weaving commenced from one corner. A double twist shall be carefully
done by means of a strong iron bar, five half turns being given to the
bar at each splits.
The bottom and two ends of the grate or mattress shall be made at one
time. The other two sides shall be made separately and shall be
secured to the bottom and the ends by twisting adjacent wires together.
The top shall be made separately and shall be fixed in the same
manner as the sides after the crate of mattress has been filled.
Wherever possible, crates shall be placed in position before filling with
boulders. The crate shall be filled be carefully hand packing the
boulders as tightly as possible and not by merely throwing in boulders.
