Question 1

The most widely used type of asphalt shingle is the 3-tab (triple-tab) strip shingle. What is the approximate weight per square?

Accepted Answer

235 pounds

Answer

Explanation:
The approximate weight per square for a 3-tab asphalt shingle is typically around 235 pounds. This type of shingle is commonly used in roofing applications due to its durability, affordability, and ease of installation. Understanding the weight of different roofing materials is essential for contractors to ensure proper load-bearing capacity and structural integrity of buildings.

Question 2

What is the approximate weight of a bundle of twelve 20' ft #6 rebars?

Accepted Answer

360 Ibs.

Answer

Explanation:
The approximate weight of a bundle of twelve 20-foot #6 rebars is calculated by multiplying the weight per foot (1.502 lbs) by the length of each rebar (20 feet), then multiplying by the number of rebars (12).

Weight per foot: 1.502 lbs
Length of each rebar: 20 feet
Number of rebars: 12

Total weight = (1.502 lbs/ft * 20 ft * 12) = 360.48 lbs

Question 3

What is the name of a non-load-bearing exterior masonry wall?

Accepted Answer

Curtain Wall

Answer

Explanation:
A curtain wall is a non-load-bearing exterior masonry wall that is primarily used for aesthetic purposes and to provide weatherproofing for buildings. Unlike load-bearing walls, which support the weight of the structure above them, curtain walls are supported by the building's framework or structural components. Understanding the different types of walls used in construction is essential for contractors to ensure proper planning and execution of building projects.

Question 4

Foundation plates or sills resting on concrete or masonry foundations shall be bolted or anchored to the foundation with steel bolts or approved anchors, bolts shall be embedded not less than _______ into concrete or masonry.

Accepted Answer

7 inches

Answer

Explanation:
Foundation plates or sills resting on concrete or masonry foundations must be bolted or anchored to the foundation with steel bolts or approved anchors. These bolts should be embedded not less than 7 inches into the concrete or masonry to ensure proper anchoring and stability of the structure. Understanding foundation requirements is essential for contractors to ensure structural integrity and compliance with building codes and standards.

Question 5

The SE corner of the property is at elevation 1,422.75 ft. The property is 275 feet wide east to west. The property sits on a 3% downslope. What is the elevation in the SW corner of the property?

Accepted Answer

1414.50'

Answer

Explanation:
Slope Calculation:
Run x Slope = Rise (or Drop)
275' wide x 3% slope = 8.25' drop
1,422.75 - 8.25' = 1414.5' elevation
