Example 5.1 Using the cost information provided in Table 5.1, prepare an EXCEL file and your professional res report for the cost calculation of the structural engineering work shown in the sketch attached Figure. Assume that all site works except the excavation for footing have been completed. - All concrete to be 20MPa. - Floor slab to be placed on a sand bed and PVC membrane which runs up the edges of the slab. - Slab reinforced with one layer of F72 mesh. - Finishing of slab allowed for in rate for placing concrete. (Slab to be cured.) - No reinforcement in footings but 2/U bolts 500mm long to be cast into all footings. - All frame members to be 250 UB37 (wt 37Kg/m ) Lateral bracing (M10 tie rods) follows the pitch of the roof. (Steel density =8t/m3.) > Purlins and girts (wall supports) to be 10251 at 1200mm centres (wt 3.3Kg/m ). (BHP C10019) Building to be clad completely with 0.62mm galvanised steel sheeting. - Three doors and 15 windows to be provided. - All doors and all windows are the same size. (Do not deduct the area of doors and windows from the steel cladding area.) - Allow \$7000 for site establishment and 10% for contingencies. \begin{tabular}{|c|c|c|} \hline Item & Unit & Unitrate$ \\ \hline 1.
