The average end area method of quantifying cut and fill is often used when dealing with
long, narrow tracks, such as roads. In this method, the site is divided into stations.
Station 00 + 00 is the beginning, and station 01 + 75 means 75 feet from the beginning
station - ANS-False
6 inches of topsoil is to be removed and stockpiled for the building in the following
picture. The topsoil is to be removed 8 feet back from the perimeter of the building to
allow for working around the building and sloping the sides of the excavation. How
many bey of topsoil need to be removed and stockpiled? - ANS-68 bcy
All exposed concrete surfaces require some type of finishing. For each finish,
estimator(s) need to analyze thoroughly the operations involved, material and
equipment required, and labor hours needed to do the work. - ANS-True
Concrete is estimated by the _______________ or by the _________________ and
then converted into cubic yards dividing the number by __________________. - ANS-
cubic yard (cy) - cubic foot (cf) - 27
When estimating footings for buildings with irregular shapes and jogs, the estimator
must be careful to include the ___________________ only once. - ANS-corners
In estimating quantities, the estimator makes no deductions for holes smaller than
___________________ sf or for the space that reinforcing bars or other miscellaneous
accessories take up. - ANS-2
__________________________ footings typically have projecting formed piers that
support the building structure. - ANS-Spread
When estimating footings, columns, beams, and girders, their volume is determined by
taking the __________________________ of each item times its
_________________________. - ANS-linear footage - cross-sectional area
Concrete slab information will most commonly be found on wall sections, floor plans,
and structural details. - ANS-True
, Using a waste factor of 8 percent, determine the number of cubic yards of concrete
needed to pour two of the spread footings in the following picture. - ANS-0.42 cy
Using the following picture, calculate the following:
A. Number of dowels.
B. Length of each dowel if it turns 9 inches into the footing. Allow for 2'' of cover at each
end. - ANS-A=4 and B= 51 inches
Using the following picture, calculate the following:
A. Number of horizontal footing bars (both ways).
B. Length of each horizontal bar. Allow for 2'' of cover at each end.
C. Total weight of horizontal bars if rebar #4 unit weight is 0.668 pounds per lf. - ANS-
A=8, B= 26 inches, C=11.6 pounds
A building requires a 100-foot-long by 83-foot-wide by 5-inch-thick concrete slab. Using
a waste factor of 10 percent, determine the number of cubic yards of concrete needed
to pour the slab. - ANS-128 cy
A building requires a 100-foot-long by 83-foot-wide by 5-inch-thick concrete slab.
Determine the number of rolls of wire mesh needed for the slab. There are 750 square
feet of wire mesh per roll. Add 12 percent for lap and waste. - ANS-13 rolls
A building requires a 100-foot-long by 83-foot-wide by 5-inch-thick concrete slab.
Determine the number of long and short bars for the slab. The slab is reinforced with #4
rebar at 12 inches on center both ways. - ANS-Number of long bars= 84 bars,
Number of short bars= 101
Reinforcing bars are listed (noted) by the bar number, which corresponds to the bar
diameter in _____________ of an inch. For example, a No.7 bar (deform ___________-
inch nominal diameter. - ANS-Eighth, 7/8
Reinforcing bars are taken off by linear feet. The takeoff (workup) sheet should be set
up to include the number of the bars, pieces, lengths, and bends. Because reinforcing
bars are usually priced by the hundredweight (100 pounds, cwt), the weight of
reinforcing required must be calculated. - ANS-True
The reinforcing used in concrete may be reinforcing bars, WWF, or a combination of the
two. What does WWF stand for? - ANS-Welded Wire Fabric
Which of the following statements is not TRUE for a WWF, which is designated on the
drawings in the following manner: 4 X 8 D 8 X D 11 - ANS-both wires are smooth.
Proper curing is an important factor in obtaining good concrete. The concrete cures with
the chemical combinations between the cement and water. Curing is the final step in the
production of good concrete, which can be done by the following method(s): - ANS-A,
B, C, D, and E
