Question 1

The ____ is the base of the foundation system and is used to displace the building loads over the soil.&#10;A) veneer&#10;B) footing&#10;C) grade beam&#10;D) anchor bolt

Accepted Answer

The footing is the base of the foundation system and is used to displace the building loads over the soil. Veneer is a decorative exterior finish, grade beam is a type of foundation for load-bearing walls, and anchor bolts are used to attach structures to the foundation.

Question 2

Pressure-treated lumber can be used to frame both crawl space and basement walls.

Accepted Answer

Pressure-treated lumber is resistant to rot and insect damage, making it suitable for use in damp and dark environments such as crawl spaces and basements. Therefore, it can be used to frame walls in both of these areas.

Question 3

The most typical type of foundation used in residential construction is a(n) ____ foundation.&#10;A) grade beam&#10;B) piling&#10;C) veneer&#10;D) spread

Accepted Answer

Spread foundations are the most common type of foundation used in residential construction. They are relatively simple and inexpensive to construct and can be designed to accommodate a wide range of soil conditions. Grade beams and pilings are used in specific situations where the soil is not suitable for a spread foundation, and veneer foundations are primarily decorative and not used for structural support.

Question 4

A(n) ____ foundation system uses beams placed between vertical supports to support structural loads.&#10;A) veneer&#10;B) piling&#10;C) continuous&#10;D) grade beam

Accepted Answer

The answer of A(n) ____ foundation system uses beams placed...

Question 5

Fill material can be compacted to increase its bearing capacity.

Accepted Answer

Compaction increases the density and therefore the bearing capacity of fill materials such as soil or gravel.

Question 6

The IRC and EPA have mapped the continental United States by county and identified areas where there is a high risk of exposure to ____.&#10;A) asphalt emulsion&#10;B) termites&#10;C) radon&#10;D) coarse-grained soil

Accepted Answer

The question mentions that the IRC and EPA have mapped the continental United States by county to identify high-risk areas of exposure to a certain substance. Among the options listed, radon is the only substance that is commonly mapped by county in the United States. Radon is a colorless, odorless gas that occurs naturally in the soil and can seep into homes through cracks and other openings. It is a known carcinogen and can pose a significant health risk if levels are elevated. Therefore, the correct answer is C) radon.

Question 7

To provide added support for a foundation in unstable soil, a(n) ____ may be used in place of the foundation.&#10;A) grade beam&#10;B) anchor bolt&#10;C) nested joist&#10;D) stem wall

Accepted Answer

A grade beam is a reinforced concrete beam that spans between foundation pads to provide added support to the structure above. It can be used in place of a traditional foundation in unstable soil conditions as it distributes the weight of the structure over a wider area, reducing the stress on the soil. Anchor bolts are used to secure the structure to the foundation or grade beam, nested joists are used for flooring systems, and stem walls are typically used in conjunction with a foundation.

Question 8

The texture of the soil does not affect its ability to resist the load of the foundation.

Accepted Answer

The texture of the soil plays an important role in determining its ability to resist the load of the foundation. Soil with a fine texture like clay will have higher bearing capacity than soil with coarse texture like sand. Therefore, the texture of the soil does affect its ability to resist the load of the foundation.

Question 9

With stepped wall construction, the foundation walls may not step more than _____ in one step.&#10;A) 12&#34; (300 mm)&#10;B) 18&#34; (450 mm)&#10;C) 24&#34; (600 mm)&#10;D) 30&#34; (750 mm)

Accepted Answer

In stepped wall construction, the foundation walls may not step more than 24" (600 mm) in one step. This is to ensure structural integrity and proper load distribution.

Question 10

Adding 3/8&#34; (9.5 mm) of Portland cement parging to the exterior side of a wall will _____ proof it.&#10;A) water&#10;B) damp&#10;C) erosion&#10;D) ice

Accepted Answer

Adding 3/8" (9.5 mm) of Portland cement parging to the exterior side of a wall helps to damp proof it by creating a barrier against moisture penetration.

Question 11

Foundation walls are dimensioned face to center.

Accepted Answer

The answer of Foundation walls are dimensioned face to center....

Question 12

Which of the following is often moved to a lot when an access road is placed in a sloping site?&#10;A) fill material&#10;B) anchor bolts&#10;C) footing&#10;D) radon

Accepted Answer

The answer of Which of the following is often moved...

Question 13

The ____ wall is the vertical wall extending from the top of the footing up to the first-floor level of the structure.&#10;A) wythe&#10;B) stem&#10;C) rafter&#10;D) foundation

Accepted Answer

The answer of The ____ wall is the vertical wall...

Question 14

Lateral soil pressure can bend a wall inward, thus placing the soil side of the wall in ____ and the interior face of the wall in ____.&#10;A) compression, compression&#10;B) tension, tension&#10;C) compression, tension&#10;D) tension, compression

Accepted Answer

The answer of Lateral soil pressure can bend a wall...

Question 15

Footings are made of poured concrete and placed so that they do not extend below the freezing level.

Accepted Answer

The answer of Footings are made of poured concrete and...
