Rebated Concrete Coping , Plastering, Side Formwork To Drain Base, Concrete To Drain Base & Concrete Benching - 2E1

∴ Rebated concrete coping = 2 (Total drain length - Backlane - Entrance slab ) + P.C.slab at backlane = 2 (2359.22 - 614.09 - 707.19) + 123.30 = 2075.88 + 123.30 = 2199.18 m ∴ Plastering

= Total plastering - Entrance slab area top plastering = 4732.19 - 325.31 = 4406.88 m2

∴ Formwork to side of drain base = Side formwork of total drain base - Side formwork of entrance slab base = 1500.49 - (1106.14 x 0.15) = 1500.49 - 165.92 = 1334.57 m2 ∴ Concrete to drain base = Drain base concrete + Extra arising from entrance + Additional concrete from 345mm thk bwk = 375.13 + 137(2 x 0.15 x 0.15 x 4.037) + 19.84 = 375.13 + 24.89 + 19.84 = 419.86 m3 ∴ Concrete to benching = Concrete benching -Volume affected by entrance base detail +Additional conc.from 345mm thk bwk = 315.49 - 137 x 2 ( 0.23 x 0.168 x 4.037) + 22.22 = 315.49 - 42.74 + 22.22 = 294.97 m3 ∴ 230mm brickwork

= 230mm thk bwk + Additional bwk affected by entrance base detail = 3281.58 + 137 ( 2 x 0.168 x 4.037) = 3281.58 + 185.83 = 3467.41 m2
