Dear Sir,

                       RE:     Proposed Driveway/Parking Structure on,
                               Road Reserve adjacent to Lot 368 on CP P93115,
                               24 Currawong Crescent, PEREGIAN BEACH.
                               OUR REFERENCE: 21/8744


       We have been engaged to report on the stability of the above parking structure with particular
       attention to the imposed loadings and other actions specified for carparks in AS1170.1:2002
       Clause 3.8 (a)(1) Barriers for Light Traffic Areas. This requires the ability to withstand an
       accidental impact of 30 KN at a height of 0.5 metres above the surface from a vehicle parking
       and acting over a length of 1.5 metres.
       We are told the original structure was built in 1986 and renovated in 2003.
       The structure is currently being renovated again.
       At the time the original structure was built in 1986, the impact outlined above was to be
       resisted by tying the structure back to three concrete anchors each about 450mm in diameter
       and a 1 metre in length buried well beneath the structure. The attached drawing supplied by
       Mr. Colston shows details of the structure and the tieback arrangements. Investigation since
       has confirmed the presence of the concrete anchor blocks. We are assured fixed Wheel Stops
       will be provided.
       Based on the information supplied and our examination of the site we consider the finished
       structure will meet the requirements for carparks in Clause 3.8 of AS1170.1:2002.



Yours faithfully,
