length of a jail wall whose cross-section is given in Fig-1, the basement (60cm x
40cm) and wall is of I Class brick work in cement sand mortar 1:6 finished with
12mm thick plastering both side above GL with CM 1:6, Foundation(90x30) is
CC 1:4:8. (All dimensions in the figure are in centimetres)
DATA:
1) CC1:4:8 (1m*)-20mmA ggregate @0.92cu.m, [email protected]., [email protected]
2) Brickwork in CM 1:6(1m’), - Brick @500no’s, [email protected], Cement @0.045cu.m
3) Plaster using CM1:6( 10077), — [email protected], Cement @0.30cu.m.

5 Prepare a detailed measurement of the any FOUR item of work listed for building (25)
plan shown in Fig-2 using CENTRE LINE METHOD.
(a) Earth work excavation in foundation (b) First class brick work in CM1:6 for
superstructures (c) Cement concrete (1:2:4) excluding reinforcement and
shuttering for Roof and lintel (d) Wood work for Door & Window frames (e )
painting of window grating
W2 (150cmx150cm) & D(120cmx210cm), Room size shown in the figure are
inside dimensions. (Assume any missing data —State the assumptions clearly)

6 a) A simply supported beam of size 450 x 230 having a span of 6m is supported ona (10)
30cm wall at both ends. The stirrups of 10mm diameter are provided at a spacing
of 150mm c/c. The beam have main bar of 3 no’s 20mm diameter at bottom
including one bend up bar and stirrup holders are of 2 no’s 16mm diameter at top.
Main & Stirrup holder reinforcement is provided with a cover of 25mm. Calculate
the total quantity of the reinforcement required for the stirrup for this beam. Also
prepare an estimate of tor steel reinforcement for stirrup including cutting,
bending , placing in position and binding, adopt the rate ೩5 Rs.95/kg. (Assume
any missing data —State the assumptions clearly)

b) Calculate the quantity of earth work for a portion of road of length 700m. (15)

Formation width of road is 8m, side slope in banking 2: 1 and 1:1 in cutting, road

has a down gradient of | in 150, formation level 160 at distance 0.
