20190520 - Structural Engineers Response to NSC RFI Letter - Received 26-02-2020 · 132002.220015.1

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,
