                                                                         TOO "NSULTING


1.0   Summary

      The proposed residence at 71 Seaview Terrace, Sunshine Beach comprises the
      following:

      •        Generally two living levels
      •        Access driveway at road level/roof level, ramping down to garage level
      •        External terraced areas, pool and access corridors
      •        Elevated timber and steel walkway and observation deck

      The Structural design of the project will consider the steep sandy nature of the site
      and will be carried out in accordance with the relevant Australian Standard Codes
      of Practice including but not limited to the following:

      •        AS/NZS 1170 Part I             Loading Code : Dead and Live
      •        AS/NZS 1170 Part 2             Loading Code : Wind
      •        AST'NZS 1170 Part 4            Loading Code : Earthquakes
      •        AS2159                         Piling Code
      •        AS 3600                        Concrete Structures
      •        AS 3700                        Masonry Code
      •        AS 4100                        Steel Structures
      •        AS2783                         Swimming Pool Code
      •        Building Code of Australia

      The maximum loading deflection criteria to be adopted for the development is as
      follows:

      a)         Horizontal (Lateral) movement (wind and seismic)
                 Total not greater than Height/500 (at maximum permissible stress loads)
                 Inter-storey not greater than Floor to Floor Height/5f0 (at maximum
                 permissible stress loads)
      b)         Horizontal (lateral) movement of retaining walls due to horizontal loads
                 from retained soil and surcharge - not to exceed height/500.
      c)         Vertical movement (dead plus live load)
                 Slab and beams are to be designed to achieve the following maximum
                 deflection criteria

                                Incremental Deflection
      General                   Span/500 or 15mm (whichever is less)

                                Long Term Deflection
      Slabs                     Span/500 or 15mm (whichever is less)
      Beams                     Span/500 or 15mm (whichever is less)
      Spandrel Beans            Span/500 or 15mm (whichever is less)

          Total allowable       20mm max to end spans
          (Slab I Beam)         20mm to internal spans
          Cantilever            Span/250 or 10mm (whichever is less)
          The structural framing system is to comprise a reinforced concrete frame utilising
          permanent reinforced concrete slabs, beams and columns. External decks and the
          garage floors are to be 40 MPa reinforced concrete slabs and beams. All piled
                                                                                           3
