a)              WARRAGAMBA DAM RAISING STAGE 3A

In June 2016 the NSW Government announced the Hawkesbury-Nepean Flood Risk Management Strategy (the Strategy) to reduce the potential flood risk to life, the economy and social amenity in the Hawkesbury-Nepean Valley.

In support of this announcement, Infrastructure NSW (INSW) completed a ‘strategic’ program business case.  That business case recommended, as part of a portfolio of measures for the strategy, raising Warragamba Dam by around 14m for flood mitigation (the Project).  WaterNSW is leading the delivery of the next stage of the Warragamba Dam wall raising Project for Infrastructure NSW (INSW), who are managing the delivery of the strategy for the NSW Government.

This next stage of the Project (termed Stage 3a), is the development of a final business case for the construction of raising Warragamba Dam by around 14m.  The development of the final business case is being undertaken jointly with INSW.  To assist in completing the final business case, WaterNSW will be undertaking further investigations, optimising the concept design, additional water modelling, programming, cost estimation, completing an environmental impact statement and obtain planning approvals.  WaterNSW and INSW will jointly obtain all necessary legal and regulatory approval with the final business case being completed in mid-2019.

b)              BROKEN HILL PIPELINE

The Darling River and the Menindee Lakes Storages Scheme, located approximately 100km to the southeast of Broken Hill, provide the primary means of water supply drought security via the existing above ground Menindee pipeline.

Ongoing water supply security concerns and water shortages periodically affect Broken Hill. To secure the water supply requirements of Broken Hill and surrounding communities, the proposed solution has been adopted to source water from the Murray River near Wentworth and pumping via a 270 km pipeline to Broken Hill’s existing Mica Street Water Treatment facility and Stephens Creek reservoir inclusive of associated infrastructure. The intended completion for these works is late 2018.

WaterNSW are seeking to engage a suitable entity to undertake independent probity for these works.  Tenderers should note the following regarding the works:-

·        WaterNSW may have several tendering packages running at the same time

·        Several of these works may have very short lead times, so we need to be able to respond to these requests immediately

·        Reviewing best procurement model to use for the large value/complex capital projects

·        There maybe third parties to these works that need to be considered i.e. electricity providers

The type of works that maybe required includes but not limited to the following:

·        Ensure that probity issues are promptly identified and managed for stage 3a of Warragamba Dam Raising and Broken Hill Pipeline projects.

·        The Independent Probity Advisor, shall participate in the Request For Tender process (RFT). This shall include further post tender examination of offers, discussions with tenders and the final scoring/assessment of tenderers. However the probity advisor shall not sit on the tendering panel as a scoring member.

·        The Probity Advisor shall supply a report to be attached to Tender Evaluation report for each tendered package. As maybe requested by WaterNSW.

• The Probity Advisor maybe requested throughout the life of these projects to advise and assist on other probity matters which maybe requested by WaterNSW.

The Tenderer’s must be able to demonstrate a minimum of 5 years’ experience in providing probity advice for major government institutions on infrastructure projects with each having a construction value in excess of $100M in below table. Should the tenderer not be able to satisfy the above criteria, then WaterNSW reserve the right to consider the tenderer offer, as a non-conforming tender and may not proceed any further with the tenderer’s offer.
