NOTES

1. Dredging for interim navigation access
ONLY. No ongoing maintenance dredging.

2. Dredging is to be entirely within water
allocation area [NRS-RE-001]. Final location
& extent to be determined after pre-start
survey to accommodate channel movement
prior to works.

3. Middle channel presently dominant. Aerial
photo [Feb 2011] overlay is approximate
only

4. Itis anticipated that dredging works will
include enhancement [widening &
deepening] of existing channel. May involve
enhancement or creation of secondary
channel to provide alternative access if
required

5. Expected volume: < 20,000m°
6. Temporary navigation aids to be provided by
the Contractor throughout the works to the

satisfaction of Regional Harbour Master

7. Permanent navigation aids to be installed as
requires by Regional Harbour Master.

1.4. Waves
Hs 1m [nominal]
Potential wave conditions at the foreshore are expected to vary in
response to prevailing channel configurations.

2. Materials - Geotextile and Sand-filled Geotextile Mega-Containers

24; Containers to be fabricated using ELCOMax 1209RP geotextile (or equivalent). Expected lifetime
25 years.

2:2: Container length to be 20m [may be altered if necessary or preferred by contractor].

2.3: Containers to have suitably spaced filling ports [MIN 3 preferred] with "screw & glue" closure types.

2.4. Geotextile underlay to be ELCOMax 600R (or equivalent)

25s Geotextile flaps, where required, are to be of sufficient size to provide a 30m x 6m flap. Flaps are to
be fabricated using ELCOMax 600R (or equivalent). Flaps are to be adequately secured (e.g.
stiched) to the bottom of the container.

26; If flaps cannot be fabricated, may be replaced with separate geotextile fabric with 1m laps.

3. Filling of Containers
3.1. Excavation tolerances
Vertical +/- 0.2m
B12. Containers to be filled in accordance with manufacturer's specifications using either jetpump, dredge
or suitable alternative.
3:3. Design filled container dimensions as shown.
3.4. Finished container tolerances
Horizontal +/- 1.0m from design alignment [containers to be well butted together]
Vertical +/- 0.5m at any single point
+/- 0.3m averaged over 10m

4. Maintenance

4.1. Nominated geotextile is more robust than the standard geotextile, however may be subject to
damage from vandalism, vessel impact, anchors etc.

4.2. Structures to be inspected periodically and after all major events.

4.3. Any minor damage is to be repaired as soon as practicable.

4.4. Any major damage or deflation and the container is to be replaced.

4.5. If damage is an ongoing concern, consideration may need to be given to armouring the structures
[e.g. with rock].

46. Scour may require topping up with additional containers or placing of rock in scour holes

5. Monitoring
5.1. The natural system is highly variable. Monitoring is to be undertaken in accordance with ICM Report
"Option Review - Noosa River Spit" to determine the performance and impacts of the works.
5.2. Works may be modified or removed if monitoring indicates that this is necessary.
5.3. Implementation of later stages of the works to be undertaken as required.
