Excavated earth from foundation trenches shall not be placed within:
0.5 m of trench edge
0.75 m of trench edge
1.0 m of trench edge
1.5 m of trench edge
Which method of earthwork calculation gives the highest accuracy?
Mid-sectional area method
Mean sectional area method
Trapezoidal rule
Prismoidal formula
Minimum clear cover for reinforcement in columns shall be:
25 mm or bar diameter
30 mm or bar diameter
40 mm or bar diameter
50 mm only
In third class buildings, flooring is generally an earthen floor finished with gobri washing.
True
False
Distribution bars in slabs primarily resist bending tensile stresses.
True
False
Assertion (A): Prismoidal formula is preferred for high-value earthwork projects. Reason (R):
Because it provides higher accuracy in volume calculation.
Because it is the simplest method available.
Because it requires less data than other methods.
Because it is faster to compute than other methods.
Specifications describe the nature, class of work, __________ and workmanship.
materials
costs
duration
location
