Question 6

A 24-foot long serpentine garden wall was originally designed to be double wythe, built from standard bricks. The client would like to know the cost difference to build the wall out of decorative concrete masonry units, also of a standard size of 8” x 8” x 16”. The concrete masonry unit wall will have the same footprint, size, and shape. The concrete masonry units are $2.10 each and the bricks are 80 cents each. The wall in both cases is 16” tall with a concrete cap.

Considering only the given difference in material costs, what is the cost difference between the two walls?

Answer 6

Incorrect - the answer is 270.00

To answer the question, we need to find the number of concrete masonry units and the number of bricks that will be needed to build the wall. Drawing a picture can help. Keep in mind that nominal sizes are implied in this question.
First the concrete masonry units: The wall is 24’-0” which is 288” long. Since a concrete masonry unit is 16” long, there will be 18 units for each course. Since the wall is 2 courses high, we will need 36 concrete units to build the wall.
Now the bricks: Find how many standard bricks at 8” long are needed to build the 288” long wall. 288” divided by 8” is 36 bricks. That is just one wythe and one course. We have 2 wythes and 6 courses, so multiply 36 times 12 for 432 bricks.
Now calculate the costs and then the cost difference: 36 concrete units at $2.10 each totals $75.60. 432 bricks at $0.80 each totals $345.60. Subtract $75.60 from $345.60 for a cost difference of $270.00.

Question 7

Answer 7

Light output is measured in lumens.

Question 8

For the design of new hostess area at a restaurant, a decorative brick wall is proposed. The bricks should have a uniform appearance and will be laid up with narrow joints.

Answer 8

Type FBX requires the highest level of manufacturing precision, meaning they are the most suitable for an application where the joints are narrow, providing little tolerance for variations in size and shape. FBX bricks also have the lowest tolerance for chippage, providing the uniform appearance that is called for.

Incorrect. Type FBS is general purpose face brick and has a wider size variation than this application calls for.

Incorrect. Type FBA permits a greater variance in size and shape among bricks, making it unsuitable for an application with tight joints.

Incorrect. NW is a brick grade, not a brick type like the other answers. NW brick is for use in locations with negligible weathering.

Question 15

An existing exterior wall of a small library is constructed with 4” nominal lumber at 12” on center, and batt insulation between the studs. The resulting U-value of this assembly has been measured to be 0.25. An architect has been retained to increase the thermal performance of the building, and they have determined that the best way to do this is to add 2” of continuous rigid insulation to the exterior of the home. The rigid insulation has an R-value of R-4 per inch.

What is the resultant U-value of the assembly after the additional rigid insulation is added?

Answer 15

0.083
Correct. To find the answer, first find the total R-value of the rigid insulation based on the R-value per inch given in the scenario.

4 x 2 inches = 8

The rigid insulation has an R-value of 8. Next, find the R-value of the existing wall by taking the reciprocal of the U-value.

1 / 0.25 = 4

Now add the R-value of the rigid insulation to the R-value of the existing wall.

4 + 8 = 12

Finally, to find the U-value of the proposed assembly, take the reciprocal of the total R-value.

1 / 12 = 0.083

Question 48

It is estimated that an 18-foot-long steel column having a cross-sectional area of 30.8 square inches will bear an axial live load of 900 kips. Using the formula L=(PxL)/(AxE) where P is the axial load, L is the length in inches, A is the cross-section area in inches, and E is the modulus of elasticity of steel (29,000 kips / sq. in), what will be the change in height of the column?

Answer 48

The column will shorten by the following equation. L = (P x L) / (A x E) where L= change in length [in] P = 900 kips L = 18 ft = 18 x 12 in = 216 in ``` A = cross section of the column = 30.8 sq. in ``` E = modulus of elasticity for steel members = 29,000 kips/ sq. in Thus, L = (900 x 216) / (30.8 x 29,000) L = 0.2176 in

Question 50

The following graphic depicts the ceiling plan for an office. The lighting requirements for the office are to have an even 40 footcandles of light on the desk surface which is assumed to be 3 feet above the floor. The ceiling is 9 feet high. The ceiling is a 2 by 2 lay-in grid. Drag the lights on the left and place them in their appropriate locations on the ceiling plan to meet the lighting requirements. Use the minimum number of fixtures that will meet the requirement.

Answer 50

9 ft high ceiling – 3 ft work plane = 6 ft from the light fixture to the desk surface. Following the 40 footcandles graph line, we can see that at a vertical distance of 6 feet below the light fixture, there are 40 footcandles of light at a horizontal distance of 2 feet from the fixture. This means that no part of the office should be more than 2 feet horizontally from a light fixture. Therefore, light fixtures should be no more than 2 feet from the wall, and there should be no more than 4 feet between fixtures, or 2 feet on each side.

These codes will require the building to be more airtight than the architect previously has designed. Which of the following must accompany a more airtight building envelope?

Answer 52

High quality weather barrier Correct. An airtight wall cannot dry out because there is no air flowing through it. Having a high quality weather barrier helps keep the wall dry. Weather barriers are placed on the outside of buildings and they work to prevent bulk water intrusion into the wall while allowing moisture from inside the wall to diffuse back out. High-efficiency furnace Incorrect. High efficiency furnaces may accompany this building type, but will not contribute to a more airtight building. Attic ventilation Incorrect. Attic ventilation is required by code and will accompany this building type but this is not a response to buildings becoming more airtight over the years. Attics are ventilated to keep cold roofs cold in the winter and to remove moisture and heat in the summer. Increased insulation Incorrect. Increased insulation wouldn't make the building anymore airtight than before. It would increase thermal performance with a higher R-value.

Question 53

An architect is designing a building in a humid climate that subjects the building to great swings in temperature. The architect would like to use a curtain wall system. What is a primary concern that the architect needs to account for in the design of the facade?

Answer 53

Thermal expansion and bowing of the curtain wall skin Correct. The curtain wall will bow outwards due to thermal expansion under hot summertime conditions. Twisting of spandrel beams due to thermal expansion Incorrect. Twisting might occur, but do to the weight of the curtain wall, not thermal expansion. Structural stresses due to irregular floor plans Incorrect. No information was given regarding the floor plan. Differential foundation settling Incorrect. We do not have enough information to know if there will be differential settling.

Question 54

The specification writer asks the architect what level of specifications they are expecting at the construction document submission. What should the architect tell the specification writer?

Answer 54

Three-part specifications Correct. This is appropriate for construction document level development, but the owner–architect agreement should be referenced. Performance specifications Incorrect. Performance specifications are a type of specification; the question is asking what level of specifications should be provided. Outline specifications Incorrect. This is more appropriate for earlier phases of the project. Basic material systems and system selection Incorrect. This is appropriate for schematic design.

Question 55

A frameless glass door is proposed for an executive office. The door has glass sidelights on both sides for a minimal aesthetic. Which type of hinge should be specified?

Answer 55

Pivot Correct. Pivot hinges located at the top and bottom of the glass door provide a minimal look and work well for a heavy glass door. Mortise Incorrect. Mortise hinges do not provide a minimal aesthetic on glass doors. Butterfly Incorrect. Butterfly hinges are used for cabinetry. Piano Incorrect. A piano hinge is continuous and would not achieve a minimal aesthetic.

Question 56

The joints within the laminations of a glue-laminated beam must transfer stresses from one piece of wood to another. Which type of joints are used within the laminations of glue-laminated beams? Check the two that apply.

Answer 56

Scarf Correct. A scarf joint transfers both compressive and tensile strength from one lamination to the next. Finger Correct. A finger joint transfers both compressive and tensile strength from one lamination to the next. Butt Incorrect. Butt joints are not used within the laminations of glue-laminated beams. Rabbet Incorrect. Rabbeted joints are not used within the laminations of glue-laminated beams. Dado Incorrect. Dado joints are not used within the laminations of glue-laminated beams. Mortise and tenon Incorrect. Mortise and tenon joints are not used within the laminations of glue-laminated beams.

Question 57

Transitions between different building elements require special attention to prevent water and/or air infiltration. What elements should be included at the sill condition in a masonry veneer wall backed up by concrete masonry units (CMU)? Select the four that apply.

Answer 57

Vinyl weep insert Correct. Weeps allow moisture above the through-wall flashing to be vented from the wall cavity. Through-wall flashing Correct. Through-wall flashing is located below the window frame sill and provides a path for moisture that infiltrates through the veneer out of the wall cavity. Cavity drainage material Correct. Cavity drainage material is employed above through-wall flashing to ensure that mortar droppings do not interfere with the flashing or weeps venting the wall cavity. Polyurethane sealant Correct. Sealants are employed at the perimeter of window frames and adjacent masonry to retard against the intrusion of moisture. Soldier course Incorrect. A soldier course is a decorative element not associated with ensuring the integrity of the wall’s watertightness. Brick tie Incorrect. Brick ties are required for anchoring the veneer to the CMU substrate and are part of the wall structure and are not associated with the wall’s watertightness.

Question 58

A change was made in the field that is contrary to the design intent provided in the construction documents. The architect has rejected this change but the owner approves of it. Does the contractor have a responsibility to change the work to meet the design intent?

Answer 58

No, the owner approves of the change and, as long as it doesn’t violate code, the owner has the last say Correct. The owner has the final say when it comes to nonconforming work. No, the contractor has the ability to change the work as he or she sees fit once the building is being constructed Incorrect. The contractor must build to the intent of the drawings. Yes, It must meet the design intent of the drawings. No exceptions. Incorrect. There is room for exceptions as long as the correct sign-off is followed. It is up to the architect to determine whether it should be changed back to the original design intent Incorrect. It is the owner’s decision.

Question 59

The architect is trying to select the best masonry joint based on waterproofing. Which of the following joints should they select?

Answer 59

Weather-struck Correct. Weather-struck joints are sloped to allow rainwater to run off, so they would be the best choice. Dry Incorrect. Dry joints mean there is no mortar. In terms of providing the most weather-resistant wall, dry joints are not the best choice. Flush joint Incorrect. Flush joints mean the face of the mortar is flush with the face of the masonry, so they are less water resistant than other kinds of joints. Flush joints are for when a stucco coating is to be applied over the masonry. Raked Incorrect. Raked joints mean the face of the mortar is set back from the face of the masonry. This would allow water from rain to sit on the masonry, eventually leading to water infiltration problems in the wall.

Question 60

A proposed retaining wall abuts the property line. Which type of retaining wall should be used?

Answer 60

L-type cantilever Correct. An L-type cantilever retaining wall is a vertical stem wall and a slab base that looks like an L. It is constructed this way so that the wall may abut a property line or other obstruction. T-type cantilever Incorrect. A T-type cantilever type wall is not appropriate for a zero lot line location. This is because the base slab has both a heel and a toe and thus cannot position the vertical face to be on a property line. Counterfort Incorrect. A counterfort type wall is not appropriate for a zero lot line location. This is because the base slab has both a heel and a toe and thus cannot position the vertical face to be on a property line. Battered Incorrect. Battered is a word used to describe a retaining wall with a vertical face that slopes or steps back.

Question 61

An architect has been asked to assist on the redevelopment of an urban neighborhood to make it more pedestrian-friendly. What ratio of street to building is most likely to accomplish this?

Answer 61

1:1 Ratio Correct. This brings the facades closer to the street and has the narrowest ROW. 2:1 Ratio Incorrect. This would make for a 100' ROW and about a 44' building height. It feels wide and has much more street to building frontage. 3:1 Ratio Incorrect. This would allow for a park or boulevard down the center of the aisle, but feels very car-oriented. 5:1 Ratio Incorrect. This is not a typical ratio for street design.

Question 62

In the absence of a geotechnical report, during the initial excavation the presence of ground water is found 1 foot beneath the surface. In preparing the foundation details, the architect should provide what kind of protection at the exterior face of the stem wall?

Answer 62

Waterproofing Correct. Waterproofing is required when there's the presence of groundwater. You would also need to dewater the site therefore reducing the risk of hydrostatic pressure against the stem wall. Damp proofing Incorrect. Damp proofing is only required when there's no presence of groundwater. Flashing Incorrect. Flashing would not be appropriate below grade. Drainage Plane Incorrect. Drainage plane would be part of the waterproofing system.

Question 63

A steel beam is required for a renovation project where the load-bearing walls will be removed. The architect selects a beam based on the desired depth. The structural engineer runs the load calculations and selects a beam with more material located further from the neutral axis. The engineer's beam selection provides greater resistance to which of the following?

Answer 63

Bending Correct. Bending forces in a beam are resisted when more material is located farther from the neutral axis. This is why a deeper beam can carry more load.

Question 64

An architect is writing the specifications for a new mixed use building. While writing the architect has determined that for quality and price control it is best to use different types of specifications for the different building components. Which of the following exemplifies a performance-based specification?

Answer 64

Exhaust fans shall be rated for continuous operation at capacity of 500 CFM against a static pressure of 0.5 inches of water column and temperature of 150 degrees Fahrenheit. Correct. Performance specifications set forth the desired result, not the means of achieving it. Steel Shear Connector Studs shall conform to the requirements AISC 360 section M2, item 4 and AWS D1.1-10 Incorrect. This specification is an example of a reference specification. Toilet tissue dispensers to be Bobrick B-76867 Classic Series surface mounted for two rolls in stainless steel with satin finish. Quantity as shown in drawings. Incorrect. This specificationis an example of a proprietary specification. Sand for grouting shall be screened to pass a 30 mesh sieve with not more than 5% passing a 100 mesh screen. Sand shall be clean, washed, sharp, durable natural particles, free from soluble salts or organic impurities. Incorrect. This specification is an example of a descriptive specification.

Question 65

Following the bidding phase, the owner decides to value engineer the project due to budget overruns. The contractor suggests using vinyl windows, as opposed to the originally-specified aluminum-clad wood windows, and the team accepts. Six months after the windows are installed, it is determined that their U-value never met the code minimum. Who is at fault?

Answer 65

The architect Correct. The architect is responsible for specifying the original quality and allowing the VE change. The manufacturer Incorrect. The manufacturer would be at fault if the window assembly failed, but that isn't the case here. The owner Incorrect. The architect is the design professional in charge of the quality of materials. The contractor Incorrect. The contractor submits the substituted product to the architect for approval.

Question 66

An architect is designing a series of townhouses in a hot humid climate with heavy precipitation. The architect needs to detail the exterior wall in a way that keeps moisture out of the wall.

Answer 66

Pressure-equalized rainscreen Correct. In a hot, rainy, and humid climate, a method to control moisture is to use a pressure-equalized rainscreen. The rainscreen assembly includes a ventilated cavity that prevents moisture from getting into the wall. It is suitable for all climates, but especially ones with high levels of precipitation.

Question 67

The architect is designing a ramp in an assisted living facility and is checking the drawings for code compliance. Select the statements that are true regarding accessible ramp design. Select the three that apply.

Answer 67

Vertical changes of ¼ inches do not require ramping Correct. Ramps are required when height changes are greater than 1/2 inch. Accessible ramps are limited to a 30-inch rise before a landing is required Correct. Refer to ADAAG 405.6. A ramp landing required area may overlap a required door maneuvering clearance Correct. Door maneuvering clearances and ramp landings are allowed to overlap. Ramps in senior living facilities cause insurance premiums to go down Incorrect. Ramps in senior living facilities make insurance premiums higher because they are tripping hazards. Handrails, edge protection, and vertical posts may obstruct the minimum required width of an accessible ramp Incorrect. Protrusions into the required clear width of accessible ramps are not allowed. A ramp that rises 4” must have handrails. Incorrect. Handrails are required on ramps that rise more than 6 inches.

Question 68

Gas fireplaces are purchased and installed as a unit. HVAC air handling unit Incorrect. Air handlers are manufactured, purchased, and installed.

Question 69

An electrical circuit has a voltage supply of 10 Volts and a current of 5 mA. What is the resistance?

Answer 69

2000 ohms The current that will flow in a DC circuit is directly proportional to the voltage (V) and inversely proportional to the resistance (R) of the circuit (i.e., Ohm’s law). Ohm's law is often written as I = V/R or V = IR. To calculate the resistance, rearrange the equation and solve for R. R = V / I ``` V = 10V I = 5mA = 0.005A R = 10V / 0.005A = 2000 ohms ```

Question 70

The plans for a new community room show light switches in three different places, each serving a different entry point into the room. All serve the same group of overhead light fixtures. What type of switches should you see in the plans?

Answer 70

Three four-way switches Correct. Four-way switches are used when connecting three different switches to the same light or group of lights. Three three-way switches Incorrect. Three-way switches are used when two switches connect to the same fixtures. Three two-way switches Incorrect. Two-way switches are not used when more than one switch connects to the same fixture. Three one-way switches Incorrect. There is no such thing as a one-way switch.

Question 71

Expected level of quality is hard to convey in a construction project. Workmanship can vary and expectations among builders, suppliers, owners, and architects can differ. Which actions are likely to get the quality of workmanship that is expected? Check the four that apply.

Answer 71

Require samples or mock-ups Correct. Having samples and mock-ups establishes criteria by which the final product can be judged. Require a certain known manufacturer or supplier Correct. This can help guarantee a higher level of workmanship. Required conformance to applicable standards Correct. Referencing standards such as those published by ANSI gives an objective criteria to measure the work. Establish inspection requirements Correct. Work that passes certain inspection procedures provides an expected level of workmanship.

Question 72

The funding stipulations for a new museum require the building to achieve at minimum a LEED certification. The architect has neglected to include sustainable products and procedures in the material schedule and specifications, which are needed to achieve LEED certification. What is the potential consequence of this exclusion?

Answer 72

If the design team is contractually required to achieve a level of LEED certification, it could be considered as a breach of contract if points are missed. Correct. If specific information is not included in the specifications, the correct products to ensure LEED certification might not get incorporated.

Question 73

During the bidding process, the contractor prices out wood windows for a new school project. After receiving the bid, the owner wants to value engineer the windows. What is the cheapest option available?

Answer 73

Vinyl Correct. Vinyl would be the best option. Aluminum clad wood Incorrect. Aluminum clad wood would be the most expensive option due to it being a combination of aluminum and wood. Fiberglass Incorrect. Fiberglass would be the second cheapest option. Aluminum Incorrect. Aluminum would be the third cheapest option.

Question 74

A one-story building with a story height of 10 feet is being designed. One of the columns needs to be sized. The column will be select structural grade pine lumber. The allowable unit stress is 1450 psi. The column must carry a load of 16,000 pounds. Use the equation f=P/A where f is stress, P is load, and A is area. What is the smallest column that will support the required load?

Answer 74

Correct. To solve the problem, first rearrange the equation given to solve for A (area). A=P/f Now, fill in the values for P (load) and f (allowable stress). A=16,000/1,450. Solving for A, we get 11 square inches. A 4x4 column provides 12.25 square inches (3.5 inches times 3.5 inches) and is therefore the most efficient size that will carry the load.

Question 75

The design of a small cafe has a self-service area where patrons can help themselves to packaged snack items and pay for them at the cash register.

A structural engineer is designing wood beams for a ski lodge and needs to calculate the section modulus. Which of the following is used to calculate the section modulus of a piece of lumber? Check the three that apply.

Answer 77

Actual dimensions Correct. The section modulus is a property of a body’s cross- section—that is in part determined by the vertical dimension from the centroid to the top (or bottom, because they are the same). Vertical distance from the centroid to the top of the section Correct. The section modulus is the formula S = I/y, where y is the distance from the centroid to the top (or bottom). Moment of inertia Correct. The section modulus is the formula S = I/y, where I is the moment of inertia. Moisture content Incorrect. The section modulus is a property of a body’s cross-sectional shape; as a result, moisture content is not considered. Nominal dimensions Incorrect. Nominal means “named.” To calculate the section modulus we need actual dimensions, not nominal ones. Species Incorrect. The section modulus is a property of a body’s cross-sectional shape; species is not considered.

Question 78

An architect is assembling a drawing set. In addition to plans and elevations, the architect has included a sheet with wall sections. What information is conveyed in a wall section?

Question 80

The architect has specified that the copper roofing shall be installed with galvanized steel fasteners. What is the most likely outcome in this scenario?

Answer 80

Galvanic action will occur causing corrosion and deterioration of the fasteners Correct. The galvanized steel fasteners are the anodic metal in the galvanic couple. The anodic metal has the smaller surface area of the two. Together, this leads to corrosion of the anodic material.

Question 81

As a piece of wood loses its natural moisture, shrinkage occurs. Which type of shrinkage is most prominent in solid lumber?

Answer 81

Tangential Correct. Tangential shrinking is the most significant type of shrinkage. It is the type of shrinkage that occurs parallel to the growth rings. Radial Incorrect. Radial shrinking is the second most significant type of shrinkage. Radial shrinking is perpendicular to, or across, the growth rings. Cupping Incorrect. Cupping is not a kind of shrinkage. Cupping is a type of warping due to tangential shrinkage. Longitudinal Incorrect. Longitudinal shrinking is practically negligible. This type of shrinking affects the length of a piece of wood.

Question 82

The architect is coordinating with the electrical engineer on a voltage drop issue in the circuit that ties together three of the main offices. Which of the following could be causing the voltage drop in the circuit?

Answer 82

Impedance Correct. Voltage drop refers to the reduction in voltage or voltage loss due to impedance. Transformer Incorrect. Voltage is increased or decreased by transformers using induction coils. This is not voltage drop, which is voltage loss due to impedance. Fuse Incorrect. Fuses break circuits to protect against overcurrent; they do not cause voltage drops. Circuit breaker Incorrect. Circuit breakers are safety devices; they do not cause voltage drops.

Question 83

A shelf must be mounted at a height which allows a person in a wheelchair to use it from a side approach. Based on accessibility codes, what is the maximum height for mounting a shelf?
