The CMC subcontractor has completed the additional acceptance testing required by geotechnical contractor, GHD. However, due to heavy rainfall and drilling contractor unavailability, installation of additional soil nails was postponed until 2025. To prevent collapses during the Christmas break, CMC covered the excavation with plastic sheeting.

Progress on the Blue Knob Road landslip project is progressing well. The soil nail installation at the first site is complete
and shotcrete works will commence shortly. Drilling is underway at Site 2 and 3 with soil nailing started at end of the
month and expected to continue throughout September

The drilling and soil nail installation at the first site are complete, and testing is scheduled for early August. Meanwhile, drilling has begun at the second site, and clearing and excavation work are underway at the third and fourth sites.

Work is progressing on the first of four landslip sites along Blue Knob Road. Contractor CMC is currently focused on the
site closest to Nimbin, where they are constructing two soil nail walls. Once this stage is underway, they will proceed to
establish the second site for excavation.

Works began to rectify the first of two landslip sites on Blue Knob Road in late May. The road will remain open under stop-go traffic control to have minimal impact on residents.
