PILING
SLEEVING/CAPPING EXISTING PILE
Delete as required
1.1
Sleeving Concrete Piles
Where shown on the Drawings, the Contractor shall cut off the existing concrete pile and sleeve it with a new 305 mm x
305 mm x 12 mm pile. The pile shall be installed in accordance with Part 4 "Pile Driving", except that it shall be
driven to 1 m penetration below sea bed level.
Excessive marine growths shall be removed from the concrete pile prior to driving. After completion of the pile
driving, the gap between the concrete pile and the steel pile shall be filled with a high-workability neat cement slurry so
as to displace all water. A concrete plug shall be placed inside the steel tube to the level of the top of the pile and air
voids removed by vibration. The pile shall be sealed in accordance with Clause 300.4.9. Concrete shall be Grade N32
and comply with AS 1379 "The Specification and Manufacture of Concrete".

Underwater Noise From Piling
A diagram showing the Observation Zone and Shut Down Zone is provided in Appendix X.
If pile driving is to be undertaken during the migratory period for cetaceans and pinnipeds using South Australian
coastal waters (1st May to 31st October) the Contractor shall:
(a)Advise the Superintendent a minimum of 48 hours prior to commencing pile driving activities;
(b)At all times 30 minutes prior to and during pile driving, ensure observations are undertaken by a spotter to
determine if cetaceans/ pinnipeds are present within the 3km ‘Observation Zone’;
(c)Implement measures to minimise the noise generated by pile driving, eg by utilising vibro-piling (or other lownoise piling methods)instead of impact piling, where feasible;
(d)Provide a spotter to undertake pre-start visual observations for cetaceans and pinnipeds for at least 30 minutes
prior to commencement of pile driving activities and for the duration of pile driving activities. The spotter shall:
 Monitor and observe the locations and movement of cetaceans/ pinnipeds in the vicinity of the works in
accordance with this part;
 Upon observing a cetacean/ pinniped within the designated ‘Observation zone’, make a determination
as to whether the cetacean/ pinniped is likely to enter the ‘Shut Down Zone’, based on current direction
and movement. If so, piling must cease as soon as practicable
 Notify the Site Supervisor immediately when a cetacean/ pinniped is sighted and is within the
designated ‘Observation and/or Shut Down Zone’;
 Document sightings in a daily register, including date, time, approximate numbers of cetaceans/
pinnipeds and calves, location, directional movement, zone, stop work notification and timing of
notification to the Site Supervisor. This register is to be provided to the Superintendent upon request
and at the end of the pile driving.
(e)Notify the Superintendent when cetaceans/ pinnipeds come within the designated ‘Shut Down Zone’ of the works;
(f) Ensure that no pile driving activity is undertaken if a cetacean/ pinniped is present in the ‘Shut Down
Zone’.
