4. WHAT WILL DIFFER TO THE TEXT N. PRESTON, M. MARTIN CERT IV ESTIMATING 2012 The descriptions will be the same But some working out will be different So I suggest you make a new copy on a new P10 Then insert it into your text as a sample Also note, my items will all appear up the top of the page, YOU will continue yours as you now know, from page to page

5. FIRST ADDRESS BEAM SIZE N. PRESTON, M. MARTIN CERT IV ESTIMATING 2012 We assume the angle here is 45° Therefore the 200 width will equal the 200 height Therefore for ease of calculation, we use ½ this width and extend the base size to create a rectangle Making it now 500mm wide for future calc’s Similarly the central beam applies to both sides making it 600mm wide New beam width
