We, Cardno (Qld) Pty Ltd, advise that the proposal to construct the works
described above has been checked by us. When the works are constructed in
accordance with the approved drawings and in the location shown, the proposed
works are structurally adequate for the anticipated usage in this location and
should comply with the design and safety provisions of the Prescribed Tidal Work
Code (Schedule 4A of the Coastal Protection and Management Regulation 2003),
based on the design criteria, and assumptions listed below.


Basis of Design Advice

           •    The works do not impose loads that would significantly affect existing
                structures.
           •    The works do not adversely affect the stability of the bed and banks in
                the near vicinity of the structure.
           •    Structural design criteria:


Maximum Wave Height                            600mm wind wave
                                               600mm boat wake
Wind Classification                            N3
Max. Current                                   1.4 m/s parallel to face of pontoon
Scour                                          Reasonable scour effects from flood flows and
                                               tidal flows have been considered
Debris Load                                    To AS 3962
Impact Loads                                   Minor loads without some damage to structure
Max Vessel Size berthed                        7.0 metres length (wet) & 3.1 metres beam (wet)
Relevant Codes                                 AS1170, AS 3962 and AS 3600, except where
