  1. Identify and produce estimated costs for projects Part Lesson 4 – Slab on Ground N. Preston, M. Martin Cert IV Estimating 2012

  2. Worked Example – From P 82 section 2 in text • Measure and extend in accordance with the ASMMBW Edition 5 • Specification Notes • • All concrete work to be 2OMPa • • I 0mm Diameter bar: 0.616 kg/m • • All stirrups to have 100mm hook end allowance to each end • • Allow one layers of F82 fabric to ground slab and one layer of4F 12TM trench mesh to edge beams • • Allow `Z' bar of 400mm long, 200mm and 300rnm cog ends at 500mm centres to all perimeter edge beams only • • Allow 50mm concrete cover to all reinforcement • • Allow steel trowel finish to all concrete surface • • All formwork to be Class 4 N. Preston, M. Martin Cert IV Estimating 2012

  3. First lets clarify No. ‘s • 10.000m • 4.400m • 500mm / 120mm • 200mm • 400mm / 200mm • 200mm / 400mm / 200mm • 200mm / 400mm N. Preston, M. Martin Cert IV Estimating 2012

  4. What will differ to the text • 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 N. Preston, M. Martin Cert IV Estimating 2012

  5. First address beam size • 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 N.
