NEW QUESTION # 23
A revolving door is to be mounted in the facade of a building. Story drift is limited to 0.002 times story height in any direction. The door can tolerate a maximum departure from vertical of 1/4 inch.
What is the maximum height the door can be to accommodate the story drift?
- A. 9 ft
- B. 10 ft
- C. 11 ft
- D. 8 ft
Answer: B
Explanation:
Given:
Maximum story drift ratio = 0.002 × story height (H)
Maximum door tolerance (max lateral displacement allowed) = 1/4 inch = 0.25 inch Since the door can tolerate up to 0.25 inch displacement, the maximum height to prevent exceeding drift is about 10.4 ft.
But check options-since 10.4 ft is closest to option B: 9 ft or option C: 10 ft?
The maximum height to accommodate the drift is just over 10 ft, so option C: 10 ft is correct.
Correction to Verified answer: C. 10 ft
Summary:
Max drift = 0.002 × H
Max drift # 0.25 inch
Solve for H # 125 in = 10.4 ft
Door can tolerate max 10 ft height to not exceed drift

NEW QUESTION # 24
A family-owned apple farm in the Upper Midwest is taking advantage of a change in the local zoning code that added a new Agri-Tourism class in the existing farm zone. This allows the Owner to build a new facility on their existing site. The building will be open to the public and include a brewery, distillery, tap room, and market. The architect is ready to submit the drawings to the Owner for the 50% construction documents review.
To accommodate a compressed construction schedule, the Owner will be utilizing a design-build process. The Contractor has submitted the Pre-Engineered Metal Building (PEMB) shop drawings to the Architect for review, due to the lead time on this critical path item. Once construction begins, farming operations must be able to continue uninterrupted.
Key project information includes:
* Brewing and distilling will operate year-round.
* Brewery will initially include four fermenting tanks. Owner has requested space for at least two additional tanks. Potential expansion will be based on future sales.
* Distillery will produce 16% alcohol, which is classified as a flammable liquid. Fire separations are required.
* Tap Room is designed with seating for 300 people, not including exterior patio seating. It will have views to the working orchards and the historic buildings on site.
* Tap Room is scheduled to be open from August through November. Owner would like options to extend operating dates based on popularity.
* The Market area will feature local farm products and is not conditioned.
* Entire building will be fully sprinklered.
* Selected building materials are low-maintenance, as requested by the Owner, for durability and to reflect the nature of a working farm.
* Mechanical and electrical systems will be hung from the building structure. These loads are included in PEMB shop drawings.
* Public water and sewer is not available at the Project Site.
* Occupancy sensors are included to reduce utility costs and achieve energy conservation requirements.
The following resources are available for your reference:
* Architectural Drawings, including plans, elevations, sections, and schedules
* Consultant Drawings, including structural, HVAC, power distribution, and plumbing
* PEMB Shop Drawings
* Design and Construction Schedule
* Specification Excerpts, showing relevant spec sections
* IBC and ADA Excerpts, showing relevant code and accessibility sections
* After reviewing the documents, the architect discovers a coordination issue in the corridor.
Which modification is required?
- A. Add exit sign at door number 15.
- B. Relocate supply and return air diffusers.
- C. Add access panel for shut-off valves.
Answer: C
Explanation:
At 50% CDs with early PEMB coordination and compressed schedule, typical cross-discipline clashes in corridors involve above-ceiling valves/dampers that lack required access from a public space. Plumbing and mechanical codes require accessible, labeled access panels for isolation/shut-off valves (and similar devices) located in concealed spaces so they can be serviced without disrupting operations-critical here because farm work must continue during construction/operation.
Exit sign at door #15 (A) depends on egress analysis; not a generic coordination issue.
Relocate diffusers (B) is a comfort/layout decision, not a compliance coordination issue unless they conflict with lights/sprinklers.

NEW QUESTION # 25
A significant advantage of glass-fiber-reinforced concrete panels over architectural precast concrete panels is which one of the following?
- A. Increased strength
- B. Decreased weight
- C. Increased quality control
- D. Decreased fabrication time
Answer: B
Explanation:
Glass-fiber-reinforced concrete (GFRC) panels offer several advantages compared to architectural precast concrete panels:
GFRC panels are lighter due to their thin profile and use of fiber reinforcement, reducing structural load and facilitating installation.
Precast concrete panels are heavier and thicker.
Strength of GFRC is adequate but typically not higher than traditional precast.
Quality control and fabrication time are comparable or vary depending on the project and fabrication process.
Therefore, the significant advantage is decreased weight.

Per the current energy code, the building envelope requirement for walls above grade in this climate zone is R13 + R10c.i.
What specification section must be added to the project?
- A. Specification Section 072100: Thermal Insulation
- B. Specification Section 075419: Polyvinyl-Chloride (PVC)
- C. Specification Section 072119: Foamed-In-Place Insulation
Answer: A
Explanation:
The energy code requirement R-13 + R-10 c.i. (continuous insulation) for above-grade walls necessitates adding/confirming a thermal insulation section that covers both cavity insulation (R-13) and continuous exterior insulation (R-10) (e.g., rigid boards, mineral wool boards). Section 072100-Thermal Insulation is the correct overarching specification.
072119 Foamed-In-Place is a product-specific section and not required unless using SPF as the c.i.
075419 PVC is roofing.

NEW QUESTION # 27
An architect is designing a new poured-in-place concrete residential tower with individual condo units. The drawings specify exposed cantilevered concrete balconies with glass guardrail parapets. The exterior wall specifications have already been developed and established. They are now coordinating the specification requirements for construction of the balconies in the project manual.
Which items are required to be specified as part of the balcony scope? (Check the four that apply)
- A. Glazing system
- B. Door types
- C. Furnishings
- D. Floor finish coating
- E. Drainage
- F. Guardrail anchoring
Answer: A,D,E,F
Explanation:
In NCARB ARE 5.0 PDD, balconies are considered part of the building envelope and exterior assembly, requiring coordination between structural, architectural, and sometimes MEP elements. The project manual's specification sections for balconies should include all components integral to the balcony's construction and performance - not unrelated furnishings or general door types unless they are directly part of the balcony system.
Reasoning for each selection:
A). Drainage - REQUIRED:
Balconies must include drainage provisions to prevent standing water, freeze-thaw damage, and leakage into units. This is part of Division 07 (Thermal and Moisture Protection) in the CSI MasterFormat and directly tied to durability and code requirements.
B). Floor finish coating - REQUIRED:
The balcony surface finish must be specified for slip resistance, durability, weather resistance, and integration with waterproofing membranes. This is usually in Division 09 (Finishes) but referenced in Division 07 for waterproof coatings.
E). Guardrail anchoring - REQUIRED:
Structural anchorage details for the glass guardrail parapets must be specified to meet IBC load requirements (200 lb concentrated load per IBC 1607.8) and to ensure safety. This falls under Division 05 (Metals) or Division 05/08 integration.
F). Glazing system - REQUIRED:
Glass guardrails involve tempered or laminated safety glazing per IBC Chapter 24 and must be specified, including thickness, type, finish, and installation method.
Why the others are excluded:
C). Furnishings - NOT REQUIRED: Balconies may have furniture, but these are FF&E, not part of the construction scope in the balcony specification.
D). Door types - NOT REQUIRED: Doors leading to balconies are part of the exterior wall fenestration package, not the balcony construction section.

NEW QUESTION # 29
Which document is the most appropriate location for specifying the finish material for casework?
- A. Construction Drawings
- B. Project Manual - Division 06
- C. General Conditions
- D. Outline Specifications
Answer: B
Explanation:
Division 06 (Wood, Plastics, and Composites) of the Project Manual contains detailed specifications for finish carpentry and casework materials. This aligns with ARE Objective 2.1: Evaluate project manual sections for technical accuracy.
NEW QUESTION # 30
During plan review of an office building, the reviewer informs the architect of new regulations that require storage rooms greater than 150 sf be 1-hour fire rated. The proposed design has three 200 sf storage rooms that must meet the fire protection requirements. The architect needs to recommend how to meet this requirement with minimal effect on cost, time, and program.
- A. Make four 150 sf storage rooms and redistribute throughout the building.
- B. Construct storage rooms using metal studs and Type X gypsum board.
- C. Construct storage rooms using rated concrete masonry.
- D. Make six 100 sf storage rooms and redistribute throughout the building.
Answer: B
Explanation:
When new plan#review rules require 1-hour fire-resistance for storage rooms >150 sf, the least cost/time
/program impact is typically a 1-hour gypsum board assembly (metal studs with Type X on each side per UL
/GA listings).
A). CMU: durable but higher material and labor cost; heavier, slower to install.
C/D. Splitting rooms: Avoids the rating but disrupts program, adds doors/partitions, circulation, and can increase costs and complexity.

Refer to the exhibit.
Using metal stud framing, how many screws per stud are needed to connect the header if each screw is rated at 440 pounds for shear and 215 pounds for tension?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
Given:
Load (W) = 1,600 lb
Screw shear capacity = 440 lb per screw
Screw tension capacity = 215 lb per screw
Assuming worst case is shear capacity (usually governs):
If tension applies, 8 screws needed.
But typically, shear governs for header connection; since question likely focuses on shear, 4 screws would be safest.
If question expects minimal number to resist both, 8 screws would be correct.
Final answer: 4 screws (Option C) if shear governs; if considering tension also, 8 screws (Option D).
Since the question is ambiguous, and shear usually controls, C. 4 screws is appropriate.

Refer to the exhibit.
For which of the following connections could diagonal bracing be eliminated?
- A. D
- B. B
- C. A
- D. C
Answer: C
Explanation:
The diagrams depict metal stud or curtain wall connections to structural frames under wind loading. Diagonal bracing can be eliminated when the connection itself provides lateral restraint in both directions.
A: Shows a connection with angles or plates attached to resist both in-plane and out-of-plane forces, creating a moment-resisting connection that can handle wind loads without diagonal bracing.
B, C, D: These connections allow slip or have limited fixity-requiring separate bracing to resist lateral loads.

NEW QUESTION # 33
An architect is rehabilitating a historic federal landmark that requires repairs to a garden wall. The existing brick appears to be in good condition; the mortar shows significant signs of deterioration.
Which strategy should the architect propose to repair the damaged wall?
- A. Remove loose mortar by hand raking the joints prior to repointing.
- B. Completely remove deteriorated mortar with electric saws prior to repointing.
- C. Carefully remove all mortar and repoint all joints to achieve a uniform appearance.
Answer: A
Explanation:
(PDD) Study Guide References
For historic masonry rehabilitation, the accepted approach (e.g., NPS Preservation Brief 2: Repointing Mortar Joints in Historic Masonry) is to hand#rake deteriorated mortar to a proper depth (typically 2-2½× the joint width or until sound mortar is reached), avoid power#saw removal that can damage historic brick, and match the original mortar in composition, hardness, color, and tooling.
A is incorrect because removing all mortar for a "uniform appearance" is unnecessary and risks damaging sound joints.
B is incorrect because electric saws can chip and over#cut historic brick arrises, violating preservation best practices.
C is correct: careful hand removal of loose/deteriorated mortar followed by repointing with compatible mortar is the recommended method.
PDD References: Historic fabric protection under "Codes/Regulations & Standards-Historic preservation," detailing of masonry repairs in construction documents (Division 04), and QA/QC specifications for repointing.
NEW QUESTION # 34
Specifications and details for repointing deteriorated masonry joints in historic soft-brick buildings should result in which one of the following?
- A. An increased mortar strength over the original mortar
- B. A bond between the existing masonry and the new mortar that is stronger than the brick
- C. Deeper joint profiles
- D. The duplication of original mortar strength
Answer: D
Explanation:
Understanding the Problem
This question is about historic masonry restoration - specifically, repointing deteriorated mortar joints in soft-brick buildings.
Historic bricks, especially those made before the early 20th century, are often much softer and more porous than modern high-fired bricks. The mortar originally used was also softer, usually lime-based, which allowed for thermal movement, moisture permeability, and protection of the brick units.
Why the Correct Answer is "Duplication of Original Mortar Strength"
* Best practice in preservation (as outlined in the Secretary of the Interior's Standards for the Treatment of Historic Properties) is to match the original mortar in strength, composition, permeability, and appearance.
* A mortar stronger than the original can cause the softer brick to crack or spall under thermal or moisture stresses, because the brick will end up being the weaker link and take the damage.
* Duplication ensures that the new mortar works compatibly with the old masonry system - allowing for similar vapor transmission and structural flexibility.
Why the Other Options Are Incorrect:
* B. Increased mortar strength over the original mortar - This is harmful in historic soft-brick construction. Stronger cement-based mortars can trap moisture in the brick, leading to freeze-thaw damage and spalling.
* C. A bond stronger than the brick - This would cause the brick to fail first when stress occurs, which is undesirable in preservation work.
* D. Deeper joint profiles - Deeply raking out joints unnecessarily can damage surrounding brick edges and change the visual proportions; repointing depth should only be enough to remove deteriorated mortar (typically 2-2.5 times the joint width).

NEW QUESTION # 35
In an air-conditioned space in a tropical environment, roof insulation is being applied above a structural deck.
In order to avoid problems related to condensation, where should the vapor barrier be installed?
- A. Below the ceiling
- B. Above the insulation
- C. Below the insulation
- D. Below the structural deck
Answer: C
Explanation:
In a tropical climate, the interior is cooler and drier than the hot, humid exterior. The vapor drive is from outside # inside, so the vapor retarder must be installed on the warm/moist side of the assembly, which is below the insulation when the insulation is above the roof deck. This prevents moist exterior air from reaching cooler surfaces inside the insulation where condensation could occur.
PDD Reference: Psychrometrics & vapor drive principles, PDD "Thermal & Moisture Protection-Placement of vapor barriers," ASHRAE Handbook recommendations.
NEW QUESTION # 36
The building permit plan review for a small, two-story residential project with a crawlspace issues the following comment to the architect:
"No under floor access shown in plans. Please locate and note locations of under floor access." Site conditions will not allow access to the crawlspace from the exterior.
What drawing will the architect need to update to satisfy the reviewer's comment?
- A. Second Floor Framing Plan
- B. Main Floor Framing Plan
- C. Foundation Plan
Answer: B
Explanation:
Understanding the Reviewer's Comment
* The under-floor access refers to an access opening to the crawlspace.
* Crawlspaces are located below the main floor framing and above the foundation.
* The International Residential Code (IRC) Section R408.4 requires access openings to under-floor spaces, either from the exterior or the interior.
* If site conditions prevent exterior access, access must be provided from inside the building - typically through a framed opening in the main floor.
Why the Main Floor Framing Plan is Correct
* Main Floor Framing Plan shows the joists, beams, and floor openings above the crawlspace.
* The under-floor access opening (often between joists, covered by a hatch) must be framed into the main floor structure to allow entry to the crawlspace.
* This plan will clearly show the location and framing details of the access hatch for contractor reference.
Why the Other Options Are Incorrect:
* A. Second Floor Framing Plan - The crawlspace is not under the second floor, so no access opening would be framed here.
* C. Foundation Plan - Shows foundation walls, footings, piers, and crawlspace layout, but the actual framed access opening is in the floor system above, not in the foundation drawing. The note about providing access might be referenced here, but the physical location and framing would be shown on the main floor framing plan.

Before construction documents are complete, the owner requests a review of the timeline allowed for ASIs, RFIs, RFPs, and change orders as defined in the project manual.
Which section of the project manual is relevant to this request?
- A. Supplementary Conditions
- B. Section 01 35 16 Alteration Project Procedures
- C. Section 01 26 00 Contract Modification Procedures
- D. AIA Document A201
Answer: C
Explanation:
The owner's request for review of ASIs (Architect's Supplemental Instructions), RFIs (Requests for Information), RFPs (Requests for Proposals), and change orders relates to contract modifications.
Section 01 26 00 in the project manual typically covers Contract Modification Procedures, including timelines and processes for handling these changes.
AIA Document A201 is the general conditions but does not detail specific timelines.
Supplementary Conditions modify A201 but usually don't detail these timelines.
Section 01 35 16 is specific to alteration projects, not general contract mod procedures.

NEW QUESTION # 39
Which of the following is an advantage of using a glycol-cooled air conditioning unit for a computer room?
- A. Glycol is cheaper than water for cooling.
- B. It reduces the amount of heat exhausted from the computer room.
- C. Glycol units are a sustainable cooling solution.
- D. It allows for a greater distance from the computer room to the outside unit.
Answer: D
Explanation:
Glycol-cooled air conditioning systems use a glycol-water mixture as a secondary coolant instead of plain water. Glycol has lower freezing point and better heat transfer properties in certain conditions.
Advantages include:
Longer piping runs without freezing risk, allowing the chiller or cooling unit to be located further away from the computer room, useful for flexible building layouts.
Glycol prevents freezing in cold climates or exposed pipes.
It does not inherently reduce heat exhausted or is necessarily more sustainable than water cooling.
Glycol is generally more expensive than water.
Therefore, the primary advantage is the ability to locate the cooling unit farther from the space being cooled.

NEW QUESTION # 40
In the critical path method of scheduling for new construction, the site work portion is always on the critical path due to which of the following?
- A. Site cost is usually a high percentage of the total work.
- B. Site work must be completed linearly.
- C. Retainage for site work is held until the end of the project.
- D. Site work is dependent upon short interval scheduling.
Answer: B
Explanation:
In the Critical Path Method (CPM) scheduling, the critical path is the longest sequence of dependent activities that determines the project duration.
Site work typically involves grading, excavation, underground utilities, and foundation preparation.
Site work must proceed in a linear, sequential manner: earthwork must finish before foundation pours; utilities are installed before slabs.
These activities are dependent on each other and cannot be done in parallel or out of order.
Therefore, site work forms a continuous chain of dependent activities on the critical path.
Other options are less relevant to CPM critical path logic:
Site work costs or retainage do not influence CPM scheduling.
Short interval scheduling is a project control technique, not a CPM determinant.

NEW QUESTION # 41
The client requests to limit daylighting in a second-story bedroom located in the northeast corner of a new house, especially in the mornings. The architect is considering options for the windows in terms of quantity, size, type, and location, and notes that emergency escape and rescue openings must provide a minimum clear opening of 5.7 square feet.
- A. Two 3' x 2' casement windows on the east wall
- B. One 3' x 5' double-hung window on the north wall
- C. One 4' x 4' fixed window on the north wall
- D. Three 2' x 2' awning windows on the east wall
Answer: B
Explanation:
Emergency egress requires minimum 5.7 sq ft clear opening (net).
Double-hung windows' clear opening is about half the sash area. A 3'×5' nominal size gives # 3×2.5 = 7.5 sq ft gross, ~6.25 sq ft clear # meets code.
North wall placement minimizes direct morning sunlight (vs. east wall).
A: 2'×2' awning # too small and awnings don't count for egress in most cases.
B: Fixed windows do not meet egress operability requirements.
C: Two 3'×2' casements on east wall # each only 6 sq ft gross, and east wall gets morning sun, opposite client' s goal.

NEW QUESTION # 42 
Refer to the exhibit.
An architect is working on an airport lounge project. The 9,000 SF floor plan includes an open, double-height space. Due to area limitations, all program requirements cannot fit within the 9,000 SF floor plan. A mezzanine level with one exit is being proposed to solve this programming constraint. There are adequate exits available on the main floor plan to pick up the additional occupant load from the mezzanine.
Which method of mezzanine construction should the architect design?
- A. 2,750 SF enclosed business center for 15 people
- B. 3,250 SF open dining area for 30 people
- C. 2,500 SF open lounge area for 20 people
Answer: A
Explanation:
Step-by-Step Reasoning
1. Mezzanine Area Limitations - IBC Section 505.2.1
From the exhibit:
The aggregate area of a mezzanine within a room shall be not greater than one-third of the floor area of that room/space.
Given:
* Main floor = 9,000 SF
* Maximum mezzanine size = 1/3 × 9,000 SF = 3,000 SF
2. Openness Requirements - IBC Section 505.2.3
From the exhibit:
A mezzanine must be open to the room below unless it qualifies for one of the listed exceptions.
3. Relevant Exception for Enclosed Mezzanine
Exception 1:
Mezzanines (or portions thereof) are not required to be open to the room if the occupant load of the enclosed space is not greater than 10.
Exception 3:
Mezzanines (or portions thereof) are not required to be open to the room if the aggregate floor area of the enclosed space is # 10% of the mezzanine area.
However - the scenario says:
* The mezzanine will have one exit (so it's not an open floor requiring multiple exits)
* The architect notes there are adequate exits on the main floor to handle additional occupant load from the mezzanine # This means it could be enclosed if allowed by exceptions.
4. Evaluate Each Option:
* A. 2,500 SF open lounge for 20 people
* Size < 3,000 SF # OK on area.
* Open mezzanine # Complies without needing an exception.
* But 20 occupants means more than 10 occupant load, so it can't be enclosed unless open - this one is already open, so fine.
* This works, but the question asks for which method should the architect design, and the key is the one-exit enclosed scenario.
* B. 2,750 SF enclosed business center for 15 people
* Size < 3,000 SF # OK.
* It is enclosed, and occupant load is 15, which is greater than 10. That means Exception 1 doesn't apply.
* But Exception 3 says: enclosed space can be allowed if enclosed area # 10% of mezzanine area.
Here:
* 10% of 2,750 SF = 275 SF.
* If the enclosed portion is the business center itself (full area enclosed), then it fails Exception 3.
* Wait: This would only be code-compliant as enclosed if the occupant load is # 10 (Exception 1) OR enclosed area # 10% of mezzanine (Exception 3).
* This option might work only if the mezzanine is considered enclosed but the occupant load doesn' t require multiple exits and is allowed due to adequate exit capacity on the main floor - this appears to be the intended IBC Exception 1 scenario, but since OL = 15 > 10, it technically fails Exception 1.
* The problem statement says "adequate exits available on main floor to pick up additional occupant load" - which would allow designing an enclosed mezzanine as long as total egress capacity is fine.
* C. 3,250 SF open dining for 30 people
* Size exceeds 3,000 SF # FAILS area limitation. Not allowed.
5. Conclusion
Given the constraints:
* Must fit within 1/3 floor area rule (# 3,000 SF)
* Must work with one exit and available exit capacity on main floor
* Option C fails on size
* Option A is possible but doesn't use the enclosed condition in the prompt
* Option B meets area limit, occupant load works with available exit capacity, and provides an enclosed use that matches the problem's "program requirement" scenario
NEW QUESTION # 43
Which of the following metals is best suited for embedments in concrete or masonry?
- A. Aluminum
- B. Stainless steel
- C. Cast iron
- D. Bronze
Answer: B
Explanation:
When metals are embedded in concrete or masonry, corrosion resistance is a critical factor due to the alkaline environment and potential moisture exposure.
Stainless steel has excellent corrosion resistance, making it ideal for embedments in concrete or masonry where long-term durability is required.
Bronze is corrosion-resistant but typically used for decorative or hardware applications, not structural embedments.
Aluminum corrodes readily in alkaline concrete environments and is not suitable for embedments without protective coatings.
Cast iron is susceptible to rust and corrosion in moist conditions and is generally avoided for embedded components.
Thus, stainless steel is best suited for durability and corrosion resistance in concrete/masonry embedments.

NEW QUESTION # 44
In the design of a barrier-free access route, door locksets should be equipped with which one of the following?
- A. Grip handles with thumbpieces
- B. Lever handles
- C. Knurled knobs
- D. Panic devices
Answer: B
Explanation:
For barrier-free (ADA) accessible routes, operable parts such as door hardware must be usable with one hand and not require tight grasping, pinching, or twisting of the wrist (2010 ADA Standards §404.2.7). Lever handles meet this requirement because they can be operated by users with limited grip strength or dexterity.
A). Grip handles with thumbpieces - Often require pinching or twisting; not compliant for barrier-free.
B). Knurled knobs - Non-compliant because they require twisting and strong grip; also typically used for hazardous rooms as a tactile warning.
D). Panic devices - Allowed in certain egress conditions but not the universal ADA hardware requirement for standard accessible doors.

NEW QUESTION # 45
An architect is designing a sub-surface drainage system that outfalls into a site retention pond. The recommended shape, size, and slope of the drainage lines need to be determined for primarily which of the following purposes?
- A. To obtain the desired velocity
- B. To increase the desired velocity
- C. To minimize the desired flow
- D. To maximize the desired flow
Answer: A
Explanation:
In subsurface drainage system design:
The shape, size, and slope of drainage lines are selected primarily to achieve a desired flow velocity that prevents sedimentation and clogging but does not cause erosion.
Minimizing or maximizing flow is not the goal; the system must convey the design flow efficiently.
Velocity must be balanced - too low leads to sediment build-up; too high causes pipe damage.
