Calculations Fill Fill = 16.075 – 2.5 – 2.5 = 11.075 m³ Total Fill = 11.075 m³ Reinforced Concrete for Skelton Columns = 4 × 0.25 × 0.25 × 2.40 = 0.600 m³ Beams = 4 × 3.75 × 0.25 × (0.60 – 0.12) = 1.800 m³ Slab = 4.25 × 4.25 × 0.12 = 2.1675 m³ Brick works

Total Skelton R.C. = 4.5675 m³

Brick = (4 × 3.75 × 2.40 ) – (1.00 × 1.20) – (1.00 × 2.20) = 32.600 m² Floor Tiles

Total Brick works= 32.600 m²

Floor Tiles = (4 × 4) – (4 × 0.125 × 0.125) = 15.9375 m² Total Floor Tiles = 15.9375 m² Sunday, March 21, 2010 2010 Sunday, May 16,

Calculations Plaster Ceiling Plaster = (4 × 4) – (4 × 0.125 × 0.125) = 15.9375 m² Walls Plaster = 4 × 4 × (3 – 0.12) – (1.20 × 1.00) – (2.20 × 1.00) = 42.68 m² Total Plaster = 58.6175 m² Painting Ceiling Painting = (4 × 4) – (4 × 0.125 × 0.125) = 15.9375 m² Walls Painting = 4 × 4 × (3 – 0.12) – (1.20 × 1.00) – (2.20 × 1.00) = 42.68 m² Corniche (‫)الكورنيشه‬ Corniche = 4 × 4 = 16.000 m

Total Painting = 58.6175 m²

Corniche = 16.000 m Cill (‫)الوزره‬ Cill = (4 × 4) – 1.00 = 15.000 m Corniche = 15.000 m Sunday, March 21, 2010 2010 Sunday, May 16,

Very important notes In External work: Brick works: in case of flat openings……………....Deduct all openings. in case of Curved openings…………..Deduct half openings only.

Plaster works: in case of openings less than 4m²……………......No Deduction. in case of openings more than 4m²……………....Deduct half openings only.
