Graded
Calculate the volume of top soil to be removed in cubic yards if within
a 50ft X 50ft square requires an additional lowering of pad by 0.1ft?
Ans: 9.26 cubic yards
(50x50x0.1)/(27)
1 cubic yard = 27 cubic feet

Ans: Select the appropriate word for the definition.
laser projects a single line, for example a pipe laser
laser projects fixed or rotating
laser projects a beam that can be seen 360º around the
instrument
The GPS method which utilizes (internet or radio) connection between
base receiver and rover units for collecting or laying out point positions
immediately on site is called?
Ans: Real Time Kinematic

Ans: Match the conditioning effect with its description.
When a distance is to be laid out with a chain that is too short,
the point will be set closer than it should be.
When a distance between two points is measured with a chain
that is too short, the distance that is recorded will be larger or
more than the actual length of the line.
When a distance is laid out with a chain that is too long, the
point will be set farther than it should be.
When a distance between two points is measured with a chain
that is too long, the distance that is recorded will be smaller or
less than the actual length of the line.
The __________ is widely used in construction layout and is graduated
in feet, tenths, and hundredths.
Ans: engineer's chain
