Youngs Creek, Cordeaux, Bridge Maintenance Works

Scope of works:
Works are required to protect the bridge abutments due to scouring from water. Works involve:
1. Remove built up soil from the bridge deck
2. Construct cross banks across the width of the bridge approaches to restrain water to the bridge deck
3. Regrade the existing table drains on both sides of the approaching roads and line with basalt/sandstone spalls
4. Temporary removal of existing guardrail (if necessary) and form spoon drains (mitre drains) in line with the existing drainage tracks to deviate water from table drains away from the bridge by using basalt/sandstone spalls and bio-degradable geo textile underlay
5. Fill void underneath headstock with no-fines concrete
6. Remove sandbags and place un-grouted boulders to all the sides of bridge abutment to stabilise the existing surface and reduce the water velocities
7. Reinstate existing guardrail posts using no-fine concrete
