NEW CHAINLINK STANDARD FOR SPORTING FENCING GETTING CLOSER

The CE008 Australian Standard’s committee will meet in Sydney on 28th January 2010 to consider the comments received by Standards from interested parties regarding the proposed draft Australian Standard for Chain Link security and sporting fencing.

This new standard will incorporate both the existing AS1725-2003 Chain link fabric security fences and gates and new sections on tennis court fencing, cricket net enclosures and perimeter sports ground fencing.

The Association is represented on this committee by a number of members including Chairman Ray Otter, (VIC) Craig Gibbens, (NSW) Merv Just (NSW) and Peter Kurmis (SA)

IGNORANCE IS NO EXCUSE SO THEY SAY

Recently the Association was contacted by a contractor inquiring whether AS1725 -2003 Chain - Link fabric security fences and gates was still in draft standard form.
The contractor had just completed a run of several kilometres of chain link security fencing where the specification called for the fencing to comply with the current Australian Standard.
His sub contactor had spaced the intermediate posts at 4.00 metre centres. Evidently this spacing had been the norm locally prior to introduction of the 2003 standard. The client had been made aware the current Australian standard required intermediate posts to be spaced at 3.330 centres and insisted the posts be reposted at the correct spacing and was not prepared to compromise.
AS1725-2003 is the current chain link security fencing standard. It will be replaced once the current review is completed, likely to be in early 2010. Are you sure your subcontractors are aware of the installation requirements in the
Australian standard?
