Pine Tier DSR

Overview Hydro Tasmania is seeking a suitably qualified and experienced consultant to undertake a Dam Safety Review (DSR) of Pine Tier Dam. About Hydro Tasmania is required under the Tasmanian Water Management Act 1999 and the Tasmanian Water Management (Safety of Dams) Regulations 2015 to complete Dam Safety Reviews on all dams within its portfolio with a consequence category of 'significant' or above. This legislation requires that DSRs for dams in Tasmania be compliant with the current suite of Australian National Committee on Large Dams (ANCOLD) guidelines. The tender documentation outlines Hydro Tasmania's requirements for DSRs to assist consultants with tendering for this work. Each DSR will also have an accompanying dam specific scope as an annexure based on Hydro Tasmania's current understanding of the asset. This document should be read in conjunction with the dam specific annexure when the tender is being developed. Purpose Hydro Tasmania requires a suitably qualified and experienced Expert Team (as defined by the Tasmanian Water Management (Safety of Dams) Regulations 2015) to undertake a DSR of the dam in accordance with the process described in the ANCOLD Guidelines on Dam Safety Management (2003). A Safety Review is a procedure for assessing the safety of a dam, comprising, where relevant, a detailed study of structural, hydraulic, hydrologic and geotechnical design aspects and of the records and reports from surveillance activities. A Dam Safety Review should assess the integrity of a dam against known failure modes and mechanisms for the various types of dams in terms of safe acceptance criteria (engineering standards, dam safety guidelines) or risk management criteria. Consideration of both regulatory requirements and long-term business needs are seen as fundamental to ensuring the DSR deliverables meet all required criteria and that it remains the key reference document for the asset over the next 20 years.
