Question 1

Wire "ladder" reinforcing is required in every third course of blockwork.

Accepted Answer

Wire "ladder" reinforcing is not universally required in every third course of blockwork; the requirement depends on the specific building codes, structural design, and engineering requirements of the project.

Question 2

Masonry work does not include scaffolding and hoisting.

Accepted Answer

Masonry work often involves working at heights, so scaffolding and hoisting equipment are commonly used to ensure safety and accessibility.

Question 3

Estimating the costs of masonry work involving products other than standard bricks and concrete blocks can proceed in the same way as with standard bricks and concrete blocks, and is mostly the task of the general contractor.

Accepted Answer

Estimating the costs of masonry work involving non-standard products requires specialized knowledge and expertise, and may involve additional costs for the materials themselves and specialized labor. It is not just the task of the general contractor, but may involve consultation with subcontractors and suppliers with expertise in these specific products.

Question 4

The units of measurement for masonry are generally the number of masonry pieces such as concrete blocks or, in the case of bricks, the number of thousands of clay bricks.

Accepted Answer

Masonry is generally measured in terms of the number of pieces such as concrete blocks or thousands of clay bricks.

Question 5

Bond beams are measured as "____" the blockwork in which they are required.

Accepted Answer

Bond beams are additional layers of reinforced concrete that are placed horizontally within the masonry walls to increase their structural strength. The measurement of bond beams is generally done as "extra over" the blockwork, which means that their dimensions are added to the actual height and width of the blockwork. This ensures that the bond beams fit snugly within the walls and do not interfere with the overall dimensions of the structure.

Question 6

All of the following are categories of masonry work EXCEPT:

Accepted Answer

Flood protection is not a category of masonry work, whereas fire protection, walls and partitions, and facings are all common categories within the field of masonry.

Question 7

Estimators need to be familiar with the definition of the scope of work for the masonry trade in their ____.

Accepted Answer

The scope of work for the masonry trade may vary based on the geographical location, such as seismic requirements in earthquake-prone areas or wind load requirements in coastal regions. Estimators need to be aware of these variations in order to accurately estimate the cost of a masonry project.

Question 8

Masonry work is now typically performed by subcontractors who supply the labor, materials, and equipment required to complete the work.

Accepted Answer

Masonry work is commonly subcontracted to specialized contractors who handle all aspects of the job.

Question 9

The main factors affecting the measurement of brick masonry are the size of the brick units, the size of the joints between bricks, the wall thickness, and the pattern of brick bond utilized.

Accepted Answer

The size of the brick units, the size of the joints between bricks, the wall thickness, and the pattern of brick bond utilized are the primary factors that affect the measurement of brick masonry.

Question 10

When laying brick, a(n)____ course may be required above openings.

Accepted Answer

A soldier course is typically used above openings such as windows and doors to provide added support and strength to the structure. Bricks are laid vertically with the narrow side facing out, creating a sturdy and visually appealing design.

Question 11

Bricks are available in a great number of sizes, but the Common Brick Manufacturers Association has adopted a standard size with the nominal dimensions of ____.

Accepted Answer

The Common Brick Manufacturers Association has adopted a standard size with the nominal dimensions of 2 1/4 by 3 3/4 by 8 inches.

Question 12

For the volume of mortar per square foot of wall area, the volume of brick plus joints is calculated times the volume of brick per square foot of wall area.

Accepted Answer

The volume of mortar per square foot of wall area is calculated by subtracting the volume of bricks from the total volume of bricks plus joints per square foot of wall area.

Question 13

Mortar is measured in cubic yards or cubic meters.

Accepted Answer

Mortar is a construction material used for bonding building blocks like stones, bricks, and concrete masonry units together. It is typically measured in volume, with common units being cubic yards or cubic meters, depending on the metric or imperial system being used.

Question 14

Masonry work includes construction with clay bricks, concrete bricks and blocks, clay tiles, and natural and artificial stone.

Accepted Answer

Masonry work involves using these materials to construct walls, floors, and other structures.

Question 15

A typical example of the kind of work item that is related to masonry work but may not be included in the quote from a subtrade is the item of ____ during construction.

Accepted Answer

Temporary-bracing masonry work is not typically included in the quote from a masonry subtrade because it is considered a temporary support during construction and not a permanent part of the finished structure. Foundation, reinforcing, and finishing masonry work are all essential components of a masonry project and would be included in the quote from the subtrade.

Question 16

According to The Building Estimator's Reference Book, a 4-inch (102 mm)wall with 1/4-inch (6 mm)brick joints and laid in running bond will have ____ bricks per square foot of wall area.

Accepted Answer

According to The Building Estimator's Reference Book, there are 7.5 bricks per square foot of wall area for a 4-inch (102 mm) wall with 1/4-inch (6 mm) brick joints and laid in running bond. However, since the question specifies only counting whole bricks, the answer would be 7 bricks per square foot of wall area. Therefore, the best choice is C (7).

Question 17

Trade rules in some locations require the subcontractor supplying reinforcing steel to the project to supply the rebar for the masonry work.

Accepted Answer

In some locations, trade rules require the subcontractor supplying reinforcing steel to also supply the rebar for the masonry work.

Question 18

In accordance with the general principles followed in the measurement of the work of other trades, masonry work is measured "____."

Accepted Answer

Masonry work is typically measured net in place, meaning the measurement is taken of the actual installed masonry units in their finished position, including any necessary mortar or grout. This method allows for a more accurate measurement of the actual amount of masonry work completed.

Question 19

Calculating the number of masonry units involves a ____-stage process

Accepted Answer

The answer of Calculating the number of masonry units involves...

Question 20

There are more variables to consider with concrete blocks than with clay bricks.

Accepted Answer

The answer of There are more variables to consider with...
