Deck 5: Measuring Concrete Work

Question 1

Vertical finishes are measured in _______ of exposed surface of concrete.

A)cubic feet
B)linear feet
C)cubic meters
D)square feet

Answer 1

D

Question 2

The estimator measures the surface area of the concrete that comes into contact with the forms; this is known as the ____.

A)contact area
B)displacement area
C)adsorption area
D)footing area

Answer 2

A

Question 3

Grout to anchor bolts and base plates is measured in cubic feet or cubic meters.

Answer 3

True

Question 4

Screeds can be measured in square feet or square meters as the plan area of the slab, though some estimators prefer to measure the length of the individual screed strips.

Question 5

Do not adjust the quantity of concrete for reinforcing steel and insets which displace concrete.

Question 6

Slab finishes are measured in ____.

A)square inches of plan area
B)square inches of exposed surface
C)square feet or square meters of plan area
D)square feet or square meters of exposed surface

Question 7

In general, you should calculate the volume of concrete from the dimensions given on the drawings with adjustments for "add-on" factors.

Question 8

Concrete is classified in terms of the use to which the concrete is put.

Question 9

Where there is an opening in a form system of less than 100 square feet, a deduction is made from the total area of the forms.

Question 10

Welded wire mesh shall be measured in plan area with an additional ____% included for overlaps.

A)5
B)10
C)15
D)20

Question 11

Expansion joints are measured in ____, stating the size of joint and the type of material used.

A)linear feet or linear meters
B)cubic feet or cubic meters
C)linear inches
D)cubic inches

Question 12

Linear inserts such as waterstops are measured in cubic feet or cubic meters.

Question 13

Finishes are first classified in terms of what is being finished; they are then separated by type of finish.

Question 14

Because only the ____ of formwork is measured, the estimator does not have to be concerned about the design of the forms at the time of the takeoff.

A)depth
B)height
C)volume
D)area

Question 15

Deduct for openings in the concrete that are less than one cubic foot (0.05 cubic meters)of volume.

Question 16

Preparing a quantity takeoff of concrete work requires the estimator to measure a combination of items-some of which are shown on the drawings, while others are to be inferred from the drawings.

Question 17

Saw cuts for concrete are measured in ____.

A)linear feet or linear meters
B)cubic feet or cubic meters
C)linear inches
D)cubic inches

Question 18

Concrete shall be measured in ____ net in place.

A)cubic feet
B)cubic yards
C)metric tons
D)linear feet

Question 19

Because the concrete is detailed on the drawings, it makes sense to begin the takeoff by measuring the volume of concrete in an item.

Question 20

Bulkhead forms are measured to the perimeter of the window openings, and they are the same width as the wall.
