3 Intrductin These span tables have been prepared fr the use f Quickbuilt Systems ALYSPAN Structural Aluminium Beam fr attached pati, awning, and carprt designs nly. Fr the purpses f these tables, rfs are deemed attached t an existing apprved dwelling. Australian Standards The structural sectins cmply with the fllwing Australian Standards.

4 Rf Pitch Use recmmended minimum rf pitches as specified by rf sheet supplier. The span tables in this reprt allw fr a maximum rf pitch f 5. Psts These span tables are designed fr a minimum pst size f 50 x 50 x 2.5 mm and up t a maximum height f 3.0 m. Cnstructin Ntes General The fllwing guidelines shall be adhered t at all stages f cnstructin: Verify all setting ut dimensins with architect. Cntractr shall verify all dimensins, elevatins, prperty lines etc. n the jb site. D nt btain dimensins by scaling the structural elements. Shuld any ambiguity, errr, missin, discrepancy, incnsistency r ther fault exist r seem t exist in the cntract dcuments, immediately ntify in writing t the superintendent. Maintain the structure in a stable cnditin during cnstructin. N part shall be verstressed. Temprary bracing shall be prvided by the cntractr t keep the wrks stable at all times. All wrkmanship and materials shall be in accrdance with the requirements f current SAA cdes and the by-laws, rdinances r ther requirements f the relevant building authrities. here pati cvers are t be installed n an existing pati slab, the slab shall be in gd cnditin. Psts shall be lcated where the slab is free frm cracks, deteriratin, hneycmbing r where ther pr wrkmanship exists. It shall be the respnsibility f the cntractr t shre and brace as required. Structural Aluminium All wrkmanship and materials t be in accrdance with AS 1664 except where varied by cntract dcuments Structural aluminium shall be erected plumb and true t line. Temprary bracing shall be installed and shall be left in place until ther means are prvided t adequately brace the structure. 3
