    Hello Mates,

    I am part of a group reviewing our utility's assets handed over from developers.  Can you tell me if your utility requires developers to CCTV the pipeline assets and provide that cctv as part of the handover.  We have heard some utilities ask for a certain % of the handover pipeline assets to be cctv's and others do not require cctv at all.  If you are considering options in this space, please also let me know as I would be willing to share the our outcomes with you.

    If you do recieve cctv of your pipeline assets from developers, can you also tell me about some of the challenges you have encountered?  Thanks, in anticipation.

    Hi Anne Marie.

    I know that Shellharbour are seriously considering this as a condition of Development Consent and a condition for release of Occupation Certificate.
    Early days yet however.

    Also I commend you to look at "www.vapar.co", a couple of UTS graduates who have combined Civil Engineering, AI and Deep Learning to investigate 2 weeks of a Civil Engineer looking at hours of boring CCTV footage down to 2 Minutes !! with reports showing chainage of defects, types of defects and remedial measures.
    Amanda is a Civil Engineer and her partner Michelle is a "Mecatronics" Engineer. They will presenting a paper on their service at CIVENEX at the Hordern Pavilion on Thursday 14th March.
    Amanda's Contact details. (Use my name !).

    Hi
    At Auckland Council we (Development Engineers) require all new stormwater pipes to be cctv'ed.   We have required this for a few years now and there was no real resistance. ( I believe Watercare, our Wastewater managers, require them for wastewater systems)
    The reports provided by the operators are still fairly poor so when implementing I suggest you carefully define that the log sheets are in accordance with good std practice and complete. They should also be accompanied by a comment from the engineer as to the quality of the system ensuring they have viewed them and considered the quality.
    The council reviewing engineer should also have undertaken some training on the standard practice and codes used.  This should include gaining an understanding of what the defects may mean - poor bedding, pipe failure, loading, etc and a reality check on the size of the crack ( looks big on cctv) .
    Pipe supplies are often asked to comment and will suggest that many pipe cracks will self heal. Such advise should be obtained from somewhat independent to take the pressure off the supplier. Asset owners have a different view - no need for a cracked pipe and it is now being realised defects typically occur from a small group of drainlayers.
    With all this in mind I would go to the CCPA for advise and training. They are very approachable.
    The days of torch and mirror were easier.

    The reviewing takes time so you need to ensure you have the resources and filing system. Ours are now with the Asset groups for their records.​
