CCTV prior to development handover

  • 1.  CCTV prior to development handover

    Posted 05 March 2019 20:14
    ​Hello Mates,
    I'd like to hear from water utilities as to their current practices.  Are many requiring a full CCTV of pipelines for water/sewer/stormwater prior to handover or possibly a %?  We are considering our options and interested in the current practices.  I'd also be interested to hear from others considering a review of their practices and happy to share the information we gather.

    ​Hi Anne-Maree, Here at Fraser Coast Regional Council, we require all SWD DN300 and over and all Sewer pipes DN150 and over to be CCTV'd prior to handover. This has been standard for at least the last 15 years. We also pressure test water mains and vacuum test sewers as part of the hand-over. Any defects found are rectified and re CCTV'd. These records form the baseline for future checking and monitoring.

    ​Thanks Ian
    As a former development assessment engineer and stormwater engineer, the quality of infrastructure sometimes inherited by councils has bothered me.
    CCTVing is a very useful and informative process to satisfy achieving appropriate standards.
    How did you achieve the practice/protocol?
    Was it by policy or bylaw or by development approval conditions or by inclusion in codes within the planning scheme?

    Hi Guys

    Just a quick few notes.
    * WSAA Sewerage Code (S 22.7) includes formative text on teh scopeof CCTV inspection. So, if youre using the WSAA code as the technical refernce for the construction of sewer, this section will help;
    * Within South East Queensland (SEQ), teh CCTV requirements are boosted by additonal textural ammenmdnts to the WSAA Code. The format of the CCTV files is also specified in the SEQ Asset Information Specifciation. Both are available at www.seqcode.com
    * In parts of regional Queensland its common to find either the SEQ Code or the WSAA Code referenced as a technical standard in relevant Planning Scheme Policies and this provdies the formal "head of power" to require CCTV
    * Im aware that NSW and Victoria also use WSAA Codes a lot for the same reason

    Regards
    Chris A

    Hi Alan,

    At City of Launceston we have written conditions on the planning permits requiring the CCTV of pipelines and also refer to the document  'Tasmanian Subdivision Guidelines' that was produced through LGAT in consultation with Tasmanian Council's, although to the best of my knowledge only Brighton and Sorrell Council in the south signed on to.  It is also backed up by our Council taking a bond and bank guarantee to cover a 12 months defect period and having a policy not to sela plans of subdivision unless all the criticla works are completed.

    So the short answer to your question of Ian is really that we use a bit of everything and we haven't had a lot of resistance from our developers in the almost 20 years I've been here.

    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 Anne-Marree,

    One of our member councils have it as a requirement prior to handover:
    See:
    http://www.fnqroc.qld.gov.au/files/media/original/004/0e4/5e2/87c/CP1-Construction-Procedures---0317--Issue-7.pdf
    (and doc search CCTV for hold points etc)

    http://www.fnqroc.qld.gov.au/files/media/original/003/94d/30a/1ad/CRC_CCTV_of_Stormwater_Systems_Commentary_Guidelines.pdf

    These should help, but if you need anything else, just drop me a line and I'll see what I can do!
    Cheers

    Hi Anne Marie,
    ALL new sewerage systems, stormwater pipelines, rising mains should be CCTV prior to handover.
    This is to support all the other tests conducted to ensure that we are adopting a brand new pipeline system.
    We are using public monies and we must ensure that we have checks in place for the quality of the infrastructure constructed.
    WSA-02, WSA-03 and WSA-05 are the appropriate supporting Codes of Practice.
    Regards,
    R J Allen

    Hi Anne - Maree

    I am from Queanbeyan Palerang Regional Council we are adjacent the ACT. We have large urban release subdivisions that have been under construction since 2012 which in turn are introducing many KM of Sewer, Storm water and water infrastructure, we introduced now development specifications in 2012 and reveiwe them in 2017 - 2018 for all our planning areas.

    These specification have a detailed and onerous asset acceptance testing requirements for water and sewer infrastructure, which include the 100% CCTV and conduit reporting in line with WSAA requirements for all sewer and storm water infrastructure.

    Along side this we have vacuum testing of structure and air testing of lines along with proving balls to be pulled through the line to ensure there is no deformation of the lines.

    Cast insitu structures only require 25% of all structures to be tested as opposed to precast which will require 100%.

    CCTV is a good tool but is only effective when used as part of multi faceted asset assessment / acceptance regime.

    Our design and construction specifications are underpinned by WSAA standards for where the local specification may not cover the issue.

    Following is a link to our specifications: https://www.qprc.nsw.gov.au/Building-Development/Engineering-design-and-construction-specifications

    Happy to hear alternate ideas or methods.

    Cheers

    Hi Dirk and Ann Maree.

    I note that Queanbeyan - Palarang Specifications are based on the old AUS-SPEC Series, D1 to D12 etc.
    I also understand that the new AUS-SPEC sets that are updated and published each 12 Months will include a section on CCTV specifications and may also include the Artificial Intelligence, Machine Learning review system that speeds up the review process dramatically.

    Hi Anne Maree

    AUS-SPEC national local government specifications includes1859 CCTV inspections of drainage conduits.

    This specification is applicable to the CCTV inspection and reporting of stormwater drainage and sewerage conduits for conditional assessment for maintenance and asset management purposes. It can also be used for the acceptance inspection of new assets. It includes requirements for the reporting and inspection of drainage conduits and related maintenance structures by means of CCTV equipment. It is aligned with WSA 05 Conduit inspection reporting code of Australia and is a complimentary document to the IPWEA Practice Note 5: Condition assessment and asset performance guidelines - stormwater drainage.

    AUS-SPEC provides a range of specifications, for further information visit www.natspec.com.au/products/local-government-specifications

    Please feel free to contact me if you require any additional information.
