問題 #44
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.
The owner is concerned about elevated noise levels in the Tap Room when fully occupied. The current design utilizes a 2 x 2 acoustic ceiling tile system installed above the fans. An acoustical engineer recommends noise mitigation through limiting reverberation time (RT) to 2.0 seconds or less in the space. This can be achieved by the provided ceiling material options and their corresponding area.
What should the architect recommend that will minimize additional project costs while providing the recommended acoustical solution?
答案：A
解題說明：
1. Problem Summary
* Goal: Reduce reverberation time (RT) in the Tap Room to 2.0 seconds or less.
* Current design: 2' x 2' acoustic ceiling tile system (RT = 2.0 seconds) installed above fans.
* Constraint: Minimize additional project cost.
* Recommendation from acoustical engineer: Use materials to achieve target RT without redesigning the space.

3. Interpretation of RT Values
* Current 2x2 Acoustic Ceiling Tile: RT = 2.0 seconds # meets the target exactly.
* However, fans may reduce the acoustic performance by reflecting or scattering sound, so supplemental absorption may be needed.
* Adding Acoustical Sound Board (RT = 1.6) above the existing tile system will improve absorption and lower RT below 2.0 seconds.
4. Cost & Constructability
* Retaining the current ceiling layout and simply adding a layer above is:
* Least disruptive to current design.
* Avoids redesign of the ceiling cloud layout.
* Minimizes schedule impact (critical for design-build with compressed schedule).
* Replacing with wood fiber panels (1" or 2") would require removal of existing tile, redesign of suspension, and higher cost/SF.
5. Why Other Options Are Incorrect
* A. Remove fans: This addresses air movement, not RT. Removing them does not guarantee RT improvement and conflicts with HVAC design intent.
* B. One cloud + 1" wood fiber panels: Reduces coverage area and may not meet RT goal; also costly and disruptive.
* C. One cloud + 2" wood fiber panels: Even more costly, same redesign problem as B.
* D. Retain tiles and add sound board above: Achieves RT < 2.0, minimal disruption, cost-effective vs.
full replacement # best option.

問題 #45
In winter conditions, when the outdoor air is below freezing and the indoor humidity is maintained at 40 percent relative humidity for 24 hours a day, ice forms on the exterior surface of the stone facing.
Which of the following elements is missing from the building wall section?
答案：D
解題說明：
With outdoor below freezing and indoor RH ~40% continuously, interior vapor will migrate outward. If a proper interior-side vapor barrier/retarder is missing, moisture moves through the wall and can condense and freeze at the cold exterior stone, forming visible ice. Insulation, air spaces, or rain screens help heat/moisture management, but the symptom (ice due to vapor diffusion) points specifically to the lack of an interior vapor barrier in a cold-climate assembly.

問題 #46 
Refer to the exhibit.
What is the horizontal member indicated by the arrow in the wall-floor assembly?
答案：B
解題說明：
The arrow in the wall-floor assembly indicates a horizontal structural member attached to a wall, used to support the end of a floor joist. This is called a ledger.
Ledger: Typically a dimensional lumber or engineered wood member fastened to a wall that supports floor framing members (joists).
Fire block: Installed to limit fire spread in concealed spaces-often mid-wall or mid-stud cavity, not in this floor-to-wall position.
Girt: A horizontal framing member in a wall, usually in steel-frame or post-frame construction, not in conventional wood framing for floors.
Lateral shear plate: A metal plate for shear transfer, not applicable here.

問題 #47 
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?
答案：D
解題說明：
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.
