MRWA HAS APPROVED THE USE OF CHS POSTS ON STATE ROADWORKS VIEW ANNEXURE 601
You can install CHS posts from 2.3 wall thickness as shallow as 150 mm depth and you can install a solid steel bar (recommend minum 650 mm depth footing). NB: It is the size of the concrete footing that must be altered to suit the item and conditions.
Traffic/ Parking signs
You can install traffic and parking signposts from small keep left signposts through to large double posted signs- no limit. Refer MRWA Spec 601. Keep Left signs can be installed from 150 mm depth in solid concrete islands and footpaths.
Any size or weight
As the Smart Sustainable Foundations create a self-healing shield between the footing and the item, there is no limitations upon the size, and weight of item you can install. Large double signs can be secured from 350 mm depth.
“ Our selection is not based on price alone, we also took into consideration the safety & saving aspects.The Smart Sustainable Foundations allow quick replacement of posts with no further effort required to the base, (providing a significant cost benefit in replacing the damaged sign post by re-using the existing footing ) and reduces risk of injury to employees by reducing time spent on traffic islands exposed to traffic.”
