Yanco Creek Modernisation Large Regulators (Parts 1B, 2A and 2C)

⁠⁠⁠Parts 1B, 2A and 2C of the Yanco Creek Modernisation project (the subject of this request for Expressions of Interest) relate to the construction of four new regulators

Project goals

Parts 1B, 2A and 2C of the Yanco Creek Modernisation project is part of the wider SLAM (Sustainable Diversion Limit Adjustment Mechanism) Program to improve environmental water flows.

SDLAM seeks to address both current critical water shortages, as well as establish infrastructure and processes which ensure the future environmental and economic sustainability of the Murray-Darling Basin. The objective of the SDLAM Program is to achieve similar or improved environmental outcomes for rivers, wetlands and wildlife using less water as part of the Murray-Darling Basin Plan. Project goals are to,

• improve the efficiency of how water is delivered (for example, building and improving water management structures
• deliver more efficient water use practises to save water for the environment
• remove constraints (and physical barriers) that impact the ability to deliver water into the Murray Darling Basin and where it is need most

Scope

As part of the SDLAM Acceleration Program, DCCEEW is delivering the Yanco Creek Modernisation project, which will upgrade infrastructure to enable smarter use of water in the Yanco Creek system in south-west NSW.

Parts 1B, 2A and 2C of the Yanco Creek Modernisation project (the subject of this request for Expressions of Interest) relate to the construction of four new fully automated and remotely operated regulators.

Expressions of Interest (EOI) are invited from organisations wishing to be pre-registered to tender for the proposed contract for the Yanco Creek Modernisation Large Regulators.

The core structure of the regulators is similar and includes:

• a regulator structure including concrete piers with maintenance bulkhead slots, providing housing for gates and operating system, concrete apron downstream of the structure, concrete wingwalls upstream and downstream of the structure, fixed concrete crest weir across a portion of the crest and automated lay flat gates (to be supplied by the Principal, refer to section 3.5.1 below) across the rest of the crest of the structure to assist with flow management
• a fishway comprising a low turbulence ‘keyhole’ type vertical slot fishway with allowances for variable headwater to provide upstream fish passage and automated sidewinder gates within the vertical slot fishway to allow for variable headwater conditions
• regulator access from a trafficable deck (Hartwood Regulator only) and a pedestrian walkway access part way across Wanganella and Hartwood Regulators structure for maintenance
• regulator automated controls comprising an electrical control house and Supervisory Control and Data Acquisition (SCADA) control system (A control hut for housing switch boards, telemetry equipment and SCADA system, Telemetry mast (Tower)
• crushed rock maintenance pads, access and turnaround areas adjacent to the structure
• rock beaching upstream and downstream of structure for erosion protection.
• sheet pile cut-off walls beneath the structure
• fencing of the structures to prevent public access
• signage

The project also involves the following elements:

• Power supply to the regulators provided by a mix of underground and overhead electricity cables connecting the structures to the grid.
• Permanent access tracks for maintenance, and some additional tracks to support construction only
• Track upgrades, including a new drainage culvert at the Hardwood site (also enabling works).
• Replacement of the existing Forest Creek block bank, which is associated with the Hartwood Regulator and is in a degraded condition, with a similar earthen structure in the same location.
• Construction of the Wanganella flood bypass channel to reduce potential upstream flooding impacts from the Wanganella Regulator. The channel is to enable flood waters to drain between the billabongs in the Wanganella Reserve during flood events.
• Extension of an existing privately owned borrow pit on lot 56 / DP756322 near Hartwood Weir to provide material for the construction of Hartwood Regulator and Forest Creek block bank.
• Principal provided borrow area on Conargo/Wanganella Road for the Wanganella regulator

Additional details/instructions

A mandatory tender briefing and site visit will occur on Thursday 26th June.
