### On the main level of the exploratory wing what size and shape is the steel column at U and 11?

• A.

HSS 8x8x1/4”

• B.

HSS 12x12x1/4”

• C.

W8x31

• D.

HSS 6x6x5/16”

D. HSS 6x6x5/16”
Explanation
The correct answer is HSS 6x6x5/16". This indicates that the steel column at U and 11 on the main level of the exploratory wing has a hollow structural section (HSS) shape with dimensions of 6 inches by 6 inches and a thickness of 5/16 of an inch.

### For interior partition walls what is the maximum control joint spacing unless noted otherwise?

• A.

36'

• B.

30'

• C.

18'

• D.

24'

D. 24'
Explanation
The correct answer is 24'. Control joints are used in interior partition walls to prevent cracking and control movement. The maximum spacing between control joints is typically determined by the type of construction materials and the expected movement of the wall. In this case, unless specified otherwise, the maximum control joint spacing for interior partition walls is 24 feet. This means that control joints should be placed at intervals of no more than 24 feet to ensure the stability and integrity of the wall.

### On page S1.5, what size and spacing of the reinforcing steel is required for the CMU wall on line X from 7-11?

• A.

#5’s at 48” O.C.

• B.

#5’s at 24” O.C.

• C.

#5’s at 8” O.C.

• D.

#6’s at 24” O.C.

C. #5’s at 8” O.C.
Explanation
The correct answer is #5's at 8" O.C. This means that #5 reinforcing steel bars are required for the CMU wall, and they should be spaced at 8" on center. This spacing refers to the distance between the center of one bar to the center of the next bar. The smaller the spacing, the more reinforcement is provided, which helps strengthen the wall. The size of the reinforcing steel bars is not mentioned in the question.

### For the main level gymnasium wing along column line 15 from J to K what is the lap splice length for the 12” cmu wall with #5’s at 24” O.C.

• A.

28"

• B.

46"

• C.

22"

• D.

31"

A. 28"
Explanation
The lap splice length for a 12" CMU wall with #5's at 24" O.C. along column line 15 from J to K is 28". This means that the reinforcement bars (#5's) need to overlap by 28" at the specified location in order to provide sufficient strength and stability to the wall.

### What is the lintel depth in an 8” non supported brick cmu wall if the maximum clear span is 18 feet?

• A.

8"

• B.

16"

• C.

24"

• D.

32"

B. 16"
Explanation
The lintel depth in an 8" non-supported brick CMU wall is 16". This is because the maximum clear span is 18 feet, and the lintel depth is typically half of the clear span. Therefore, half of 18 feet is 9 feet, which is equivalent to 108 inches. Since the lintel depth is typically measured in inches, 108 inches is equal to 9 feet. However, since the given options are in inches, the closest option is 16", which is the correct answer.

### On the lower level of the south classroom what base plate is required for the intersection of column lines C and 25, and how far from the edge of plate is the center of the bolt?

• A.

1’6”x1’6”x1.5”, 1.5”

• B.

1’6”x1’3”x1.125”, 1.5”

• C.

11”x11”x3/4”, 1.75”

• D.

1’8”x1’8”x1.75”, 1”

A. 1’6”x1’6”x1.5”, 1.5”
Explanation
The correct answer is 1’6”x1’6”x1.5”, 1.5”. This base plate size is required for the intersection of column lines C and 25 on the lower level of the south classroom. The center of the bolt should be placed 1.5 inches from the edge of the plate.

### Concrete masonry units shall be what type?

• A.

Medium weight

• B.

Heavy weight

• C.

Normal weight

• D.

Lightweight

D. Lightweight
Explanation
Concrete masonry units are commonly used in construction for building walls and other structures. The weight of these units is an important consideration, as it affects the ease of handling and the overall load-bearing capacity of the structure. Lightweight concrete masonry units are specifically designed to have a lower density, making them easier to handle and reducing the overall weight of the structure. This makes them a popular choice for applications where weight is a concern, such as in multi-story buildings or in areas with poor soil conditions. Therefore, the correct type of concrete masonry units to be used is lightweight.

### On the main level of the exploratory wing what size and spacing of reinforcement is required for the CMU wall along line X from 7 to 11?

• A.

#6 at 24” O.C.

• B.

#4 at 48” O.C.

• C.

#5 at 48” O.C.

• D.

#5 at 24” O.C.

D. #5 at 24” O.C.
Explanation
The correct answer is #5 at 24" O.C. This means that size #5 reinforcement bars should be placed at a spacing of 24 inches on center along line X from 7 to 11. This ensures that the CMU wall has the necessary reinforcement for structural strength and stability. The combination of size #5 bars and a spacing of 24" O.C. is the most appropriate choice for this specific area of the exploratory wing.

### At a typical CMU wall corner what is the minimum required reinforcement?

• A.

2 #5's

• B.

6 #4’s

• C.

3 #5’s

• D.

3 #4’s

C. 3 #5’s
Explanation
In a typical CMU wall corner, the minimum required reinforcement is 3 #5's. This means that three number 5 steel bars are needed to reinforce the corner of the wall. The reinforcement helps to strengthen the wall and prevent cracking or failure under stress or load. The use of three #5's ensures that the corner is adequately reinforced to withstand the forces acting on it.

### What is the spacing for horizontal ladder type joint reinforcement unless noted otherwise?

• A.

24"

• B.

8"

• C.

16"

• D.

36"

C. 16"
Explanation
The correct spacing for horizontal ladder type joint reinforcement, unless noted otherwise, is 16". This means that the horizontal reinforcement bars should be placed 16 inches apart from each other. This spacing helps to provide structural support and prevent cracking or separation in the joints of the construction.

### The minimum f’m for masonry on this project is:

• A.

2500 psi

• B.

2000 psi

• C.

3000 psi

• D.

1500 psi

B. 2000 psi
Explanation
The minimum f'm for masonry on this project is 2000 psi. This means that the masonry used in the project must have a compressive strength of at least 2000 pounds per square inch. This requirement ensures that the masonry is strong enough to withstand the expected loads and provide the necessary structural support. A higher f'm value would indicate even stronger masonry, but in this case, the minimum requirement is 2000 psi.

### The masonry units shall be laid in a stacked bond unless noted otherwise.

• A.

True

• B.

False

B. False
Explanation
The statement "The masonry units shall be laid in a stacked bond unless noted otherwise" is false. This means that the masonry units are not required to be laid in a stacked bond unless specified otherwise. The correct answer is False.

### What is an acceptable slump for the grout used on this project?

• A.

10"

• B.

5.25"

• C.

3"

• D.

11.5"

A. 10"
Explanation
An acceptable slump for the grout used on this project is 10 inches. Slump refers to the consistency and workability of the grout, and a slump of 10 inches indicates that the grout has a relatively high water content, making it easier to pour and spread. This level of slump is typically suitable for projects where the grout needs to flow into tight spaces or fill voids effectively. It allows for better consolidation and ensures that the grout will properly fill the desired areas without excessive water loss.
