             •      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:

Floating Pontoons Deck Load                              3 kPa or 4.5 kN
Maximum Wave Height                                      400mm wind wave
                                                         300mm boat wake
