Attention: Mark Lewis
Dear Mark,
8 THE ANCHORAGE, NOOSAVILLE - RENOVATED JETTY
APPLICATION NO. 132002.220015
RESPONSE TO INFORMATION REQUEST
We refer to the Operational Works application above and Noosa Council’s Information Request dated 12 February
2020.
ITEM 1.
Issue:
The submitted plan is annotated “concept for discussion” and does not include sufficient engineering detail for the
existing and proposed works.
Advice Required:
Provide engineering design plans for the proposed works. The plans must be prepared by a Registered Professional
Engineer of Queensland (RPEQ) and include sufficient detail for construction and demonstrate compliance with the
Watercourses Works Code of the Noosa Plan.
Response:
Preliminary structural engineering plans attached.
It is proposed to retain the existing concrete piles, as our engineering inspection and concrete testing have indicated
that these are in fair condition and suitable to be reused in the construction of the renovated jetty.
We are currently finalising the structural details for the non-standard elements of the new jetty framing, which
generally includes the interface between the concrete piles and new timber framing.
We are also ensuring that the design of the extended 8m long finger is suitable for mooring a larger design vessel
than in standard designs.
It is anticipated construction issue plans can be provided by Friday 6 March 2020 for approval by Council.
Attachment(s):
Preliminary Structural Engineering Plans for the proposed jetty at 8 The Anchorage, Noosaville 7609-S001 –
7609-S010
ITEM 2.
Issue
The “existing” and “proposed jetty diagrams indicate a section of decking between the 2 “finger” jetties. This section
of decking is not shown on the approved plans dated 14 March 2002 and is not in accordance with the current

Advice Required
Provide amended plans with the section of decking removed or alternatively provide justification to retain the decking
section.
Response:
The section of decking between the fingers is proposed to be retained for the following purposes:
To serve as a connection point for a future boat lift between fingers;
To conceal lighting cables run between fingers; and
To more easily walk between fingers when launching kayaks.
ITEM 3.
Issue
The submitted plan includes a notation to retain a pile that currently supports the “wing” on the existing jetty. It appears
from the plan that this pile will not be required for the proposed jetty.
Advice Required
Provide justification for the retention of the pile.
Response:
Our engineering inspection and concrete testing has indicated that the existing piles are suitable to be reused.
The pile supporting the existing “Y” shaped jetty head is proposed as one of the three piles supporting the western
side of the shorter timber finger (two new timber piles to be driven). The existing concrete piles are around 1350mm
apart, so the final width of this finger may be slightly over 1500mm wide once timber framing and decking is added.
Should you have any queries in relation to this response, please do not hesitate to contact me at our office.
Yours sincerely,
BLACK & MORE
