Rft (open):tallowa Dam Landslide Remediation and Culvert Replacement - Sr01315
npws South Coast Branch, Seeks to Engage a Suitably Qualified Contractor to Deliver Landslide Remediation and Culvert Replacement Works Along Tallowa Dam Road in Morton National Park.
please Refer to the Following Attachments for a Comprehensive Overview of the Scope:
close Date: 23-nov-2026 3:00 Pm
Tallowa Dam Road sustained significant damage during the March 2022 flood event, resulting in an active landslide and failure of associated drainage infrastructure.
Geotechnical and hydraulic investigations undertaken in 2025 confirm that the site requires remediation of the landslide and replacement of damaged culverts.
Design of the works has been completed resulting in the scope being construction only. The design which shall be released as part of tender documents has been completed by PSM Consulting Pty Ltd. The design is considered complete and NPWS does not expect that there will be any significant design changes during or as a result of the procurement activity.
If the works are not undertaken, the affected section of Tallowa Dam Road will remain closed due to ongoing geotechnical instability, posing an unacceptable risk to public safety. This will restrict access to Tallowa Dam and surrounding areas within Morton National Park, impacting NPWS operations, emergency response capability, asset maintenance access and visitor use. Ongoing instability also presents a risk of further slope failure, which could result in additional damage to infrastructure, increased remediation costs, and prolonged disruption to park access.
