Extract Design Guide Roadside signs p51

8.2.2 Sign posts
For signs less than 1m² in area, the post size is generally 50NB x 3.2mm CHS. Refer to Appendix. B for determination of post sizes suitable for larger signs or heights.

8.2.5 Posts in sleeves
There are certain situations where it is advisable to install the post into a sleeve inserted into the footing, such as:
1. Where a sign is located on an urban median strip where it may be struck frequently.
2. Where it may need to be removed occasionally, to accommodate the swept path of over-dimensioned vehicles when turning.

This arrangement is only appropriate for small posts up to 50mm nominal bore (60 O.D. CHS Posts). Details of a typical sleeve assembly are presented in Drawing No. 1368 (Appendix D). Variations on the basic theme are just as effective. "I would consider that your Smart Sustainable Foundations have an 'as-of-right' approval on this basis" John .C.Douglas Qld MR
