Refer to the house plan. How many square feet is the foundation
slab? - ANSWER-1844 sq ft
Explanation:
The easiest way to solve for the area of the slab is to image a full
rectangle of the slab and subtract void areas from the area of the
slab.
Rectangle area: 28.167' x 71.5'= 2013.94 sq ftLeft void area:
6.667' x 1.83' = 12.2 sq ftCenter void area: 11.5' x 1.83' = 21.045
sq ftRight void area: 9.167' x 15' = 137.505Net area of the
foundation slab: 2013.94 - 12.2 - 21.045 - 137.505 = 1843.19 sq
ft.
Weather conditions may make placing concrete inadvisable,
including: - ANSWER-High winds and high temperatures
Refer to the house plan. How many cubic yards of concrete needs
to be ordered for the foundation slab that is 4 inches thick? -
ANSWER-23 cubic yards

Explanation:
The easiest way to solve for the area of the slab is to image a full
rectangle of the slab and subtract void areas from the area of the
slab.
Rectangle area: 28.167' x 71.5'= 2013.94 sq ftLeft void area:
6.667' x 1.83' = 12.2 sq ftCenter void area: 11.5' x 1.83' = 21.045
sq ftRight void area: 9.167' x 15' = 137.505Net area of the
foundation slab: 2013.94 - 12.2 - 21.045 - 137.505 = 1843.19 sq
ft.Traditional Method:Multiply the area of the slab by the thickness
of the slab (in inches).1843.19 x 0.333' = 613.78 cubic
feetConvert the volume into cubic yards.613.78 ÷ 27 = 22.73
cubic yards (rounded up to 23 cubic yards)Industry Method:Divide
the area by 81 to get cubic yards.1843.19 sq ft ÷ 81 = 22.76 cubic
yards (rounded up to 23 cubic yards)

In a beam not exposed to weather or soil; what is the minimum
coverage for #4 reinforcing bar: - ANSWER-1 inch
When welding bars on sight, special attention should be paid to

the materials to be welded
Explanation:
Not all alloys used in reinforcing bar are compatible.
What is the maximum spacing of the control joints in a slab that is
to receive a floor finish? - ANSWER-joints are not necessary
Explanation:
If the carpet, hardwood floor, or other floor finishes are to be
installed on the slab, the control joints are not necessary since the
floor finishes will cover unsightly cracks in the slab.
Finishing with a steel float: - ANSWER-Reduces risk of cracking.
