a) Excavation of ground slab 100 mmTable 13 column two: 5.46 m³b) Excavation of foundation trenchTable 13 column three: 3.73 m³c) Reinforcement for foundation and ground slabMild steel rods 20 mm Ø , Table 12 column five: 214.0 m runMild steel rods 8 mm Ø , Table 12 column seven: 120.0 m runWelded mesh No. 65 or 66. Table 11 last column gives the amount for ground and roof slab. For thepurpose of this tender it is sufficient to divide this amount 2 = 68.5 m²d) Concrete as specified for foundation and ground slab. Table 13 columns two and three give theexact amount of excavation which is the same as for concrete: 5.46 m³ + 3.73 m³ =9.19 m³e) Brick wall in square metresTable 14 shows the square metres of water- proof plaster for the different sizes of reservoirs. This isthe same as the square metres of brick wall. The filling height of 3.45 m is equivalent to the height ofthe brick wall of 3.52 m. The table shows 82.9 m²Reinforcement for brick wall 10 mmØThis is the vertical reinforcement shown in drawing No. 2. Table 11 construction height 3.60 m,amount needed 89.0 m run.Reinforcement for brick wall 8 mm ØThis is the horizontal reinforcement, distribution shown in drawing No. 4. Table 12 shows theamount needed as 363.0 m run.f) Waterproof cement plasterShown in Table 14: 82.9 m²g) Reinforcement for roof slab and lintelMild steel rods 6 mm Ø for stirrups of the lintel cageTable 13 column seven: 43.0 m run.Mild steel rods 20 mm Ø main bars of lintel Table 13 column six: 42.50 m run.h) Formwork and concreting roof slab in m² Height of the slab 80 mmTable 13 column five: 49.80 m²i) Cement floor screedTable 14 last column: 44.20 m²1. Lime whitewash outside elevationTable 14 shows the square metre inside plaster for the proposed 7.50 m diameter and wall height3.52 m. The table shows 82.90 m² For the external elevation 5.5 m² have to be added (valid for allsizes): 88.40 m²76
