NCARB ARE 5.0 Project Development and Documentation Exam Sample Questions (Q34-Q39):

NEW QUESTION # 34

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

Answer: B

Explanation:
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.

NEW QUESTION # 35
A construction detail for a window sill shows metal flashing terminating behind the exterior cladding. Which principle is being demonstrated?

Answer: B

Explanation:
Proper flashing is critical for water shedding and moisture protection. Flashing behind the cladding allows water to drain outward-addressing ARE Objective 3.3: Evaluate construction details for moisture control.


NEW QUESTION # 36

Refer to the exhibit.
In the diagram shown, what is the purpose of the pressure relief valve?

Answer: A

Explanation:
Understanding the Diagram
The diagram shows a water heater (WH) with labeled connections and valves.
Item 2 is the ASME pressure relief valve, piped to 6 inches above the finished floor.
Purpose of the Pressure Relief Valve in a Water Heater
* When water is heated, it expands.
* In a closed plumbing system, this expansion increases pressure inside the water heater tank.
* If the pressure rises above a safe limit, it can damage the heater, piping, or even cause an explosion.
* The temperature and pressure relief valve (T&P valve) automatically opens to discharge water when pressure or temperature exceeds safe limits, relieving the pressure caused by thermal expansion.
Why Other Options Are Incorrect:
* A. Regulate water pressure fluctuation - Pressure regulation is done by a pressure-reducing valve, not a relief valve.
* B. Vent the tank of accumulated air - Air elimination is done with air vents or bleeders, not the T&P valve.
* D. Relieve negative pressure when draining the tank - Negative pressure prevention uses vacuum relief valves, not T&P valves.

* MEEB (Mechanical and Electrical Equipment for Buildings) - Plumbing Chapter: Safety valves in hot water systems
* Code Reference:
* International Plumbing Code (IPC) Section 504.6 - T&P relief valve requirements for water heaters Key Point:
The ASME-rated relief valve's main role is to protect the water heater and piping by relieving excessive pressure due to water expansion from heating.


NEW QUESTION # 37
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?

Answer: D

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 # 38
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 wants to add a small storage closet with dimensions of 4'-0" L x 4'-0" W in the Laundry Room along column line 1. The closet will have access from the corridor only.
Which of the following documents require revision due to this addition? Check the three that apply.

Answer: A,B,E

Explanation:
Understanding the Context
The addition of a 4'-0" x 4'-0" storage closet accessible from the corridor is a design scope modification. Even though this might appear minor, in the context of a Design-Build project delivery method, any change in the scope or spatial layout directly impacts the contract documents. Since the delivery model combines design and construction responsibilities under a single entity, accuracy and clarity in the Owner-Contractor Agreements (AIA A101, A102, or A103) is critical.
Why A101, A102, and A103 Require Revisions
* A101 - Standard Form of Agreement Between Owner and Contractor (Stipulated Sum):This document defines the scope, cost, and responsibilities of the contractor. Adding a storage closet may alter construction cost, schedule, or scope, which must be formally revised and incorporated via an amendment or change order.
* A102 - Standard Form of Agreement Between Owner and Contractor (Cost of the Work Plus a Fee with GMP):Similar to A101, but applies to projects with a Guaranteed Maximum Price (GMP).
The addition of new work, even small, may affect the GMP or contingency usage. Therefore, it also requires formal documentation of the scope change.
* A103 - Standard Form of Agreement Between Owner and Contractor (Cost of the Work Plus a Fee without a GMP):Again, even though no GMP is involved, changes to project scope must be documented for cost tracking and accountability.
According to NCARB ARE 5.0 PDD Handbook - Section: Project Manual and Contract Documents:
"The architect must evaluate how any proposed revisions to the work affect the project's scope, schedule, and budget. These revisions must be incorporated into the contract documents and may require issuing an amendment or modification to the contract." Furthermore, under Objective 4.2 - Evaluate and address changes in scope of work and scope creep, ARE candidates are expected to know when and how revisions impact contract documents.
In design-build delivery, all these contract forms must reflect any changes, even minor ones, because the contractor holds responsibility for both design and construction execution. Failure to reflect the change may lead to contractual disputes or unaccounted costs.
Why Other Options Do Not Apply
* D. Building Systems Narrative:This narrative typically outlines the design intent and basis for HVAC, electrical, and plumbing systems. A minor storage closet accessed from a corridor would not alter system layout or equipment sizing, and thus doesn't necessitate a revision to this document.
* E. Initial Cost Estimate:While the estimate may eventually need updating during cost reconciliation, the question specifically asks which documents require revision. The initial estimate is a schematic- level document that doesn't necessarily need to be revised for such a minor addition.
* F. Specification Excerpts:Unless the closet introduces new materials (e.g., special finishes, fire- resistive construction, unique fixtures), the specifications remain unchanged. The closet is likely using standard finishes already defined elsewhere in the spec.
