質問 # 30

Refer to the exhibit.
The exterior cast-in-place concrete wall of a heated building is insulated with polyurethane slabs.
The concrete will be warmest in the winter if the insulation is applied as shown in which of the following?

• A. D
• B. B
• C. A
• D. C

正解：A

解説：
To keep the concrete warmest in winter, place the continuous insulation on the exterior so the concrete mass stays inside the thermal envelope and sees interior temperatures. This reduces heat loss, limits risk of interstitial condensation at the concrete surface, and improves thermal lag. Option D shows all polyurethane insulation on the outside of the wall; A and B place some or all insulation inside, and C splits it-both allow more winter heat loss from the concrete.

質問 # 31
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.
Prior to completing the contract documents, the architect meets with the owner and confirms the scope of the new HVAC system is accurate for bidding. As a result of the meeting, the architect decides to include additional general notes on the site plan to assist the general contractor in bidding the related coordination of the new boilers being installed.
What note does the architect include?

• A. GC to coordinate location of fuel storage tanks.
• B. GC to coordinate results of city steam pressure and temperature test from utility company with boiler manufacturer.
• C. GC to coordinate gas service tie-ins with utility company.

正解：A

解説：
Comprehensive Detailed Explanation with all NCARB ARE 5.0 Project Development and Documentation (PDD) Study Guide References The project is rural with no public water or sewer; by context there is likely no city steam and possibly no natural gas main. New boilers therefore need a fuel source on site (commonly LP/propane or fuel oil), and the site plan should direct the GC to coordinate fuel storage tank location (clearances, protection, truck access, setbacks, fire code).
A presumes a gas utility service that may not exist.
B presumes a city steam utility (not present).
PDD Reference: Division 01 coordination notes; IMC/IFC for on-site fuel storage clearances and protection; site plan general notes best practices.

質問 # 32
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. Foundation Plan
• C. Main Floor Framing Plan

正解：C

解説：
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.

The architect is preparing the project manual.
What section should be included?

• A. 012300 Alternates
• B. 019113 General Commissioning Requirements
• C. 015000 Temporary Utilities
• D. 006113 Performance and Payment Bond

正解：C

解説：
Understanding the Context
When preparing the Project Manual in the Project Development & Documentation (PDD) section of the ARE 5.0 exam, you need to determine which specification sections are essential based on project requirements and conditions. The Project Manual organizes administrative and technical specifications into divisions, each serving a specific purpose.
In this case, because construction will occur while farming operations continue uninterrupted-and public water and sewer services are unavailable on site-temporary utilities (such as water, power, and possibly sanitation) are a critical component that must be clearly addressed in the Project Manual. These provisions ensure the contractor understands how to support construction without disrupting farm operations and without relying on permanent utilities.
Why "015000 Temporary Utilities" is Required
Section 01 50 00 - Temporary Utilities (often numbered 015000) is part of Division 01: General Requirements in the Project Manual. It specifies requirements for establishing and maintaining temporary utility services (like water, electric, lighting, heating, cooling, toilets) during construction. It helps ensure the design and construction team address logistical needs amid the distinctive site conditions-namely the absence of public utilities and the necessity of continuous farm operations.
As noted in a design and construction manual resource:
"Section 01 51 00 - Temporary Utilities. This section is generally included in all projects; however, it must be carefully written so as to be applicable to the specific project conditions." This directly supports inclusion of Temporary Utilities in the Project Manual for this project scenario.
Why Other Options Are Not Appropriate
* A. 006113 Performance and Payment BondThese forms pertain to contract security and bonding requirements, which would be located in Division 00 (Procurement and Contracting Requirements), not Division 01. The question focuses on which section should be included in the Project Manual being prepared at this phase; the key imperative here is the temporary utility needs, not bonds.
* B. 012300 AlternatesAlternates allow multiple pricing options for different project scopes, but there is no indication that alternate options (e.g., alternate spaces or functions) are being used in this design.
There's no mention of bidding alternates.
* D. 019113 General Commissioning RequirementsCommissioning provisions (often related to MEP system verification and performance) would only be required if commissioning is part of the project deliverables. The project brief doesn't indicate commissioning deliverables-only that mechanical and electrical systems are supported by the PEMB, and the focus here is continuity of operations and utilities during construction, not commissioning.

質問 # 34
What is the most destructive factor affecting the durability of mortar joints?

• A. Wind loading
• B. Expansion of moisture by freezing
• C. Efflorescence
• D. Location of control joints

正解：B

解説：
The most destructive factor for mortar joints is freeze-thaw cycling: absorbed moisture expands upon freezing (~9% volume increase), creating internal stresses that crack mortar and spall joints.
A: Wind loading affects wall stability, not directly mortar joint durability.
B: Control joints manage thermal/movement cracks but aren't the main durability factor.
C: Efflorescence is cosmetic and less destructive than freeze-thaw action.
PDD Reference: Masonry durability-Moisture management; ASTM C270 Mortar Specs; ARE 5.0 PDD

質問 # 35
An architect is coordinating the mechanical and structural systems in a building with exposed ceilings. The HVAC ducts are interfering with a large concrete beam in the open office area.

• A. Shift the HVAC ducts below the beam
• B. Relocate the beam to accommodate the ductwork
• C. Request the mechanical engineer to reroute the ductwork
• D. Increase the ceiling height

正解：C

解説：
In PDD, the architect must coordinate consultant drawings. When a conflict exists (here, duct vs. beam), the best course is to ask the responsible engineer (mechanical) to reroute the ductwork to clear the beam. As per ARE 5.0 Handbook Objective 3.1, the architect is expected to "coordinate building systems and their integration."

質問 # 36
Temporary shoring of a masonry wall should remain in place until what point?

• A. Foundations are backfilled
• B. Horizontal reinforcing is installed
• C. Mortar joints are struck
• D. Lateral bracing connections are complete

正解：D

解説：
(PDD) Study Guide References:
Temporary shoring in masonry construction supports walls until they gain sufficient stability. It should remain in place until:
The wall is laterally braced or tied back to a stable structure to resist wind and other lateral loads.
Mortar may have hardened but shoring removal depends on the overall stability.
Horizontal reinforcing and backfilling provide some support but do not replace lateral bracing.
Thus, temporary shoring should remain until all lateral bracing connections are complete, ensuring the wall's stability.

The owner has revised the pro forma and directed the architect to add two additional Type B units to the design. A code review for the project indicates that the building occupancy is R-2.
What should the architect do to meet the owner's required revisions?

• A. Change the 2nd Floor Unit 1BR-SW into two studios and change the 10th Floor Unit 2BR-E to two 1- bedroom units.
• B. Change the 5th Floor Unit 2BR-E to two 1-bedroom units and change the 2nd Floor Laundry to a 1- bedroom unit.
• C. Change the 10th Floor Unit 2BR-E to two 1-bedroom units and change the 7th Floor Unit 2BR-E to two
  1-bedroom units.

正解：C

解説：
Converting two existing 2-bedroom units into two 1-bedroom units each yields two additional dwelling units total, while keeping every unit on an exterior wall for light/vent and maintaining typical plumbing stacks
/egress.
A introduces two studios (size/layout risk) and alters a lower-floor stack; more coordination risk.
C converts a Laundry (likely interior and serving the building) into a unit-problematic for light/ventilation and building services.

質問 # 38
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 is dependent upon short interval scheduling.
• C. Retainage for site work is held until the end of the project.
• D. Site work must be completed linearly.

正解：D

解説：
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.

質問 # 40

Refer to the exhibit.
In the curtain wall systems shown, each of the aluminum mullions is designed to allow for which of the following?

• A. Capillary action
• B. Vertical expansion
• C. Surface tension
• D. Horizontal expansion

正解：B

解説：
1. Understanding the Diagram
The three sections in the exhibit show different curtain wall mullion profiles (vertical and horizontal sections) designed for glazing systems.
In curtain wall design, aluminum mullions must accommodate:
* Structural loads (wind, dead load of glass, seismic)
* Thermal expansion and contraction of metal members
* Building movement (floor-to-floor deflection, live load, creep, seismic drift)
2. Why Vertical Expansion is Relevant
* The vertical mullions in curtain wall systems span multiple floors and are typically anchored at one end and allowed to float/slip at the other end to accommodate vertical building movement.
* Movement can be due to:
* Thermal expansion of aluminum mullions (aluminum has a high coefficient of thermal expansion).
* Inter-story drift from lateral loads.
* Floor live-load deflection.
* The mullion joinery and connections at the anchors are specifically detailed to allow vertical sliding while maintaining weather seals.
3. Why Other Options Are Incorrect
* A. Capillary action - This refers to water movement in small spaces; curtain walls are designed with weeps and pressure-equalized cavities to prevent it, but that is not what the mullion's slip connections are for.
* B. Horizontal expansion - Horizontal movement is generally handled at horizontal mullions
/transoms or gasket joints, not the vertical mullion extrusion as shown.
* D. Surface tension - Refers to water behavior, not a structural or thermal movement design issue.

質問 # 41


An architect is designing a school building that features a flat roof with a low parapet wall in a wet climate region. The client wants to minimize maintenance requirements and focus on keeping water from the walls.
What parapet coping detail would be most appropriate for the architect to select for this project?

• A. B
• B. A
• C. C

正解：C

解説：
Understanding the Problem
The question addresses parapet coping design in a wet climate with a focus on:
* Minimizing maintenance
* Preventing water from running down the face of the wall
Parapet copings protect the top of the parapet wall from water penetration and are designed to shed water away from the wall below.
Analysis of the Options
A). Flat Coping
* A flat coping (Option A) has no slope and allows water to pool on the surface.
* This pooling increases the likelihood of infiltration and material deterioration over time.
* In wet climates, this is poor practice because standing water leads to freeze-thaw damage, staining, and faster degradation.
* Maintenance needs are higher.
B). Single-Slope Coping
* This coping (Option B) has a slope toward one side, which improves drainage.
* However, if sloped toward the inside of the parapet, it increases roof drainage load and risk of water penetration at roof/wall junction.
* If sloped toward the outside, water can run down the wall face, which the client specifically wants to avoid.
* This design might also stain exterior wall finishes over time.
C). Double-Slope (Pitched) Coping with Drip Edges
* This coping (Option C) is pitched toward both sides, with drip edges to break water runoff before it reaches the wall face.
* Water is shed away efficiently, and drip grooves prevent capillary action that would pull water back toward the wall.
* This is best practice in wet climates and greatly reduces maintenance by preventing staining and wall saturation.
* Recommended by NRCA (National Roofing Contractors Association) and referenced in Architectural Graphic Standards for parapet detailing.

* Content Area: Integration of Building Materials & Systems - Building Envelope Detailing
* Source Materials:
* Architectural Graphic Standards - Parapet Cap/Coping Details
* Building Construction Illustrated by Francis D.K. Ching - Water Management & Flashing
* NRCA Roofing Manual - Best Practices for Roof Edge & Parapet Design
* Key Principle: Parapet copings in wet climates should always slope to shed water away, incorporate overhangs with drips, and prevent water from cascading down the building face.

質問 # 42
Which of the following methods of mortar joint finishing has the greatest weatherability?

• A. Extruded
• B. Weathered
• C. Concave
• D. Raked

正解：C

解説：
Mortar joint finishes impact water resistance and weatherability:
Concave joint is the most weather-resistant. The joint is compressed and curved inward, forming a dense, compact surface that sheds water effectively.
Weathered joint slopes outward but is less compact than concave.
Raked joint is recessed and can hold water, less weather-resistant.
Extruded joint protrudes and tends to trap water and dirt.
Therefore, concave joints provide the best weather protection.

質問 # 43
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. Panic devices
• C. Lever handles
• D. Knurled knobs

正解：C

解説：
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.

質問 # 44

Refer to the exhibit.
An architect is designing a multipurpose room that will operate daycare services as well as exercise classes.
The multiple occupancies within the space utilize components of the same means of egress system.
What is the occupant load factor that should be used in calculating egress?

• A. 0
• B. 1
• C. 2
• D. 3

正解：D

解説：
Step-by-Step Reasoning
1. Identify the occupancies from the question:
* Day care services # Occupant load factor = 35 net (from table in the exhibit)
* Exercise classes # Occupant load factor = 50 gross (also from table in the exhibit, under "Exercise room")
2. Determine how to calculate the occupant load for multiple occupancies:
According to IBC 2018, Section 1004.1.2 (Areas without fixed seating) and NCARB PDD study materials:
When multiple occupancies share the same means of egress system, the occupant load for the whole space shall be the sum of the occupant loads of the various occupancies.
However, if the space is not divided and is used interchangeably (multipurpose), the most stringent occupant load factor is applied to the entire area.
3. Applying the code:
* The multipurpose room is used for both daycare and exercise.
* Since the same space is used for different functions at different times (not divided), the most restrictive occupant load factor (the smaller number) should be used.
* Smaller occupant load factor = 35 net (Day care) vs. 50 gross (Exercise room).
4. Why "net" vs. "gross" matters here:
* Net floor area excludes certain spaces like walls, corridors, mechanical rooms.
* Gross floor area includes the entire footprint.
* Even though "net" typically results in a smaller area, when calculating load factors, the smaller occupant load factor number results in a larger occupant load - making it more restrictive for egress.
5. Conclusion:
The correct occupant load factor to use for this multipurpose space = 35 net (Day care), as it results in the largest occupant load and is the most restrictive for egress design.

Refer to the exhibit.
For which of the following connections could diagonal bracing be eliminated?

• A. D
• B. B
• C. C
• D. A

正解：D

解説：
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.

質問 # 46

Refer to the exhibit.
It is required to cut a hole in the web of the beam shown.
Which of the locations would be best? Check the two that apply.

• A. Location 2
• B. Location 4
• C. Location 3
• D. Location 5
• E. Location 1

正解：A、B

解説：
Cutting holes in beam webs is common for running mechanical, electrical, or plumbing services but must be done carefully to avoid weakening structural integrity.
Holes should be located near mid-span supports (points of low bending moment and high shear) to reduce impact on beam bending strength.
Holes should not be located near areas of maximum bending moment (typically mid-span between supports), because this is where the beam experiences maximum tension or compression.
Locations 2 and 4 are at or near the beam supports (shear zones), and generally small holes can be cut there, following size limits and reinforcement guidelines.
Locations 1, 3, and 5 are closer to mid-span or areas of high bending stress, so holes here risk compromising the beam's moment capacity.
