Question 1 .5 points
The wire mesh used on the basement and over precast hollow core planks are roughly the same area. Both of these areas measure
16'10" by 25'4". Using 20% for lap and waste, calculate the amount of rolls of mesh needed if there are 750 sf in a roll.
Question options:
1.4 rolls
1 roll
2 rolls
0.7 roll
Question 2 2..5 points
To calculate the volume of a cast-in-place concrete slab on grade, the estimator should
Question options:
add 2 inches to the depth of the slab because of the uneven nature of the subgrade.
disregard openings in the slab on grade regardless of the size.
multiply the length by the width by the depth of the slab and divide by 27.
deduct the volume of the electrical conduit and plumbing pipes encased in the slab in order to not overstate the actual volume.
Question 3 2..5 points
When estimating cast-in-place concrete, the estimator must consider that
Question options:
concrete is always purchased and delivered from off-site; therefore, delivery is an additional cost to be considered.
the estimator must first design the concrete mix.
concrete is made up of cement, sand, aggregate, and water, and the quantity of each needs to be calculated.
when using ready-mix concrete, the amount of concrete required, and the type and amount of cement, aggregates, and admixtures must be
determined.
Question 4 2..5 points
, When estimating the concrete quantity of a continuous footing, the estimator should
Question options:
calculate the concrete volume for each section of the footing independently.
calculate the perimeter of the building as a good estimate of the length of the footing and multiply by the cross sectional area to obtain the
concrete volume.
for each size of footing, determine the total linear feet of the footing, calculate the cross-sectional area, and multiply these together to
calculate the volume.
not include a waste factor for the concrete since all of the pours are formed, and therefore the exact volume of concrete can be calculated.
Question 5 2..5 points
What is the total amount of reinforcement needed for the slab described below? The slab measures 23'4" by 27'0". Deduct 2" for cover
to the bars and use reinforcing bars with a weight of 0.376 pounds per foot. Reinforcing is at 12" apart in long and short directions. Add
10% for lap and waste. Round for final answer to nearest pound.
Question options:
524 pounds
480 pounds
630 pounds
476 pounds
Question 6 2..5 points
To calculate the volume of concrete for a drilled pier, the estimator must determine
Question options:
the soil conditions in order to determine how much additional concrete will be required to fill the voids left by the drilling operation.
the shaft diameter, length, bell diameter, and angle of the bell for each size of drilled pier.
only the diameter and overall length of the drilled pier because the bell is a standard size known by the drilling company.
the overall length, width, and height and multiply them together to obtain the volume of concrete.
