(4) If there is a possibility of settlement of any standard, the standard shall be provided with a foundation of such size and of such strength as to spread the load from the standard over a large enough area to prevent settlement.
(5) If splices are necessary in round pole standards, butt jointed double poles shall be used instead of single poles and the double poles shall break joint at least 9 feet, poles being secured together with 2 rope lashings at the base and 1 rope lashing on each side of each butt joint.
(6) When necessary as a protection against the impact of trucks or other heavy moving equipment, the bases of standards shall be protected from displacement by bumpers.
(7) Sawn timber standards shall be butt jointed with 2 (two) 3-feet lengths of 4 inch by 2 inch timber fixed 1 on each side of the butt joint and bolted through with 4 5 / 8 inches diameter bolts, fitted with washers and nuts, spaced at 9 inch centres.
