Building Queensland was engaged by the State Government to prepare an options assessment for Paradise Dam. This report has recommended that the following further information be gathered in conjunction with implementing the Paradise Dam Essential Works:
• geotechnical assessment of the dam foundations and development of a 3D geological model (currently underway)
• further sampling and testing of the primary spillway’s roller compacted concrete (currently underway)
• an anchoring trial to confirm existing dam foundation capacity (currently underway)
• the refinement of option designs and cost ranges using this updated information.
In partnership, Building Queensland and Sunwater will ensure this information is collected as a matter of priority, allowing government to determine the best long-term option for Paradise Dam. This process will also include information on current and future water demand, the costs of improvements and other relevant information to inform a detailed business case (DBC) which is anticipated to be completed in late 2021.
