- All the above
Answer: D
84. While estimating a reinforced cement structure, the omitted cover of concrete is assumed
- At the end of the reinforcing bar, not less than 25 mm or twice the diameter of the bar
- In thin slabs, 12 mm minimum or diameter of the bar whichever is more
- For reinforcing longitudinal bar in a beam 25 mm minimum or diameter of the largest bar which is more
- All the above
Answer: D

- 1000 m 3
- 1500 m3
- 2000 m3
Answer: C
86. While estimating the qualities for the construction of a building, the correct metric unit is
- Metre for length
- Cubic meter for area
- Square meters for volume
- Litre for capacity
Answer: D
87. Pick up the correct statement from the following:
- In order to check up the average depth of excavation, ‘Dead man’s’ are left at the mid-widths of borrow pits
- The earthwork calculation in excavation is made from the difference in levels obtained with a level
- The earthwork in excavation to form the road embankment includes the formation of the correct profile and depositing the soil in layers
- All the above
Answer: D
88. The brickwork is not measured in cu m in the case of
- One or more than one brick wall
- Brickwork in arches
- Reinforced brick work
- Half brick wall
Answer: D
89. Pick up the incorrect statement from the following:
- Lead is the average horizontal straight distance between the borrow pit and the place of spreading soil
- The lead is calculated for each block of the excavated area
- The unit of lead is 50 m for a distance up to 500 m
- The unit of lead is 1 km where the lead exceeds 2 km
Answer: D
90. The assumption on which the trapezoidal formula for volumes is based, is
- The end sections are parallel planes
- The mid-area of a pyramid is half the average area of the ends
- The volume of the Prismoidal is over-estimated and hence a Prismoidal correction is applied
- All the above
Answer: D
91. In the mid-section formula
- The mean depth is the average of depths of two consecutive sections
- The area of mid-sections is calculated by using mean depth
- The volume of the earthwork is calculated by multiplying the mid-section area by the distance between the two original sections
- All of the above
Answer: D
92. Pick up the correct statement from the following:
- The earthwork of cutting in trenches or borrow pits in fairly uniform ground is measured with the help of average depths of the dead men
- The earthwork in trenches or borrow pits in the irregular ground is measured by taking the difference in levels before and after the completion of work
- The earthwork in trenches or borrow pits, where neither a nor b is feasible, is measured from the fillings after the deduction of voids
- All the above
Answer: D
93. The cross-sections for a highway is taken at
- Right angle to the center line
- 30 metres apart
- Intermediate points having abrupt changes in gradient
- All the above
Answer: D
94. Referring to the given figure, pick up the correct statement from the following:
- The total length of the center line of the four walls is 20 m
- Length of the long wall out-to-out is 6.80 m
- Length of short walls in-to-in is 3.20 m
- All the above
Answer: D
95. Pick up the correct statement regarding the center line method of estimating a building
- The product of the center line of the walls and the area of the cross-section of any item gives the total quantity of the item
- The centre line is worked out separately for different sections of walls of a building
- The centre line length is reduced by half the layer of the main wall joining the partition wall
- All the above
Answer: D
