NCARB ARE 5.0 Project Development and Documentation Exam Sample Questions (Q90-Q95):NEW QUESTION # 90
Which of the following documents defines the responsibilities and duties of the contractor during construction?
  • A. B101
  • B. G702
  • C. A201
  • D. A101
Answer: C
Explanation:
A201 is the General Conditions of the Contract for Construction and outlines duties, rights, and responsibilities of the contractor. This includes site supervision, safety, and conformance with documents.
ARE Handbook Objective 1.4 focuses on interpreting contract documents.

NEW QUESTION # 91

Refer to the exhibit.
What is the purpose of the flexible connection in the fan coil shown?
  • A. To provide a field point of connection of the ductwork to the fan coil unit
  • B. To minimize sound transfer
  • C. To transition from the fan coil unit flange to the desired duct size
  • D. To insulate against heat transfer from the fan coil unit
Answer: B
Explanation:
Understanding the Diagram
The detail shows a fan coil unit suspended from the structure, with:
* Vibration isolators at the hanging rods to limit mechanical vibration transfer to the structure.
* Flexible duct connections between the fan coil unit and the rigid ductwork.
Purpose of Flexible Duct Connections
Flexible connections in HVAC duct systems are designed to:
* Prevent transmission of vibration and sound from the mechanical equipment (fan coil unit) into the rigid ductwork and building.
* Compensate for small misalignments between the ductwork and equipment.
* Accommodate minor thermal expansion/contraction movements.
Key Function in This Context:
Fan coil units contain fans that create vibration and noise. Without a flexible connection, this vibration would travel directly through the rigid ductwork into occupied spaces, increasing noise levels.
Why Other Options Are Incorrect:
* A. To provide a field point of connection - While the flexible connector does connect ducts, its purpose is not just convenience; it is specifically for vibration/sound isolation.
* B. To insulate against heat transfer - This is done with thermal duct insulation, not flexible connectors.
* D. To transition from flange to desired duct size - Transitions are made using sheet metal fittings, not flexible connectors.
NCARB ARE 5.0 PDD Study Guide References:
* Content Area: Integration of Building Materials & Systems - Mechanical Systems and Acoustics
* Sources:
* Mechanical and Electrical Equipment for Buildings (MEEB) - Vibration Control in Mechanical Systems
* Architectural Graphic Standards - Flexible Duct Connections for Noise and Vibration Isolation
* ASHRAE Handbook - HVAC Applications, Chapter on Sound and Vibration Control Key Point:
Flexible connectors in ductwork break the direct mechanical path for vibration and sound, reducing noise transfer from fans to occupied areas.

NEW QUESTION # 92
A project located in a rural area without municipal sewer access will most likely require:
  • A. Grease interceptor
  • B. Ejector pump
  • C. Septic tank and leach field
  • D. Oil-water separator
Answer: C
Explanation:
Where no public sewer is available, on-site wastewater treatment (septic tank + leach field) is required. This supports Objective 3.2, considering utility systems and site limitations.

NEW QUESTION # 93

Refer to the exhibit.
An architect reviews the construction manager's construction estimate for a typical precast wall system with aluminum storefront windows.
Click on the component in the axonometric detail that is missing from the system estimate.

Answer:
Explanation:

Explanation:

1. Reviewing the Construction Estimate
The listed components are:
* Architectural Precast Panels - exterior cladding
* Aluminum Storefront Windows - glazing system
* Prefinished Metal Sill Flashing - weatherproofing at sill
* Sealant - for joints between components
No line item appears for thermal insulation.
2. Identifying the Missing Element in the Axonometric Detail
Looking at the drawing:
* The detail shows precast concrete panel cladding outside.
* A storefront frame and glazing in the opening.
* There is a hatched layer behind the precast in the stud cavity area - this represents continuous insulation.
* The insulation is a required component for the wall to meet energy code R-value/U-factor requirements (per IECC or ASHRAE 90.1).
3. Why This is Critical
* Insulation is essential for thermal performance, occupant comfort, and energy efficiency.
* Omitting it from the estimate could cause:
* Noncompliance with code.
* Incomplete cost budgeting.
* Change orders during construction.
* In ARE 5.0 PDD, architects must check that all components of an assembly are represented in the cost estimate.
4. References
* NCARB ARE 5.0 Handbook - PDD Content Area 3: Integration of Building Materials & Systems
* Architectural Graphic Standards - Precast wall sections with insulation
* Building Construction Illustrated (Ching) - Continuous insulation in wall assemblies
* Energy Code References: IECC Table C402.1.3 for minimum continuous insulation requirements in exterior walls

NEW QUESTION # 94

Refer to the exhibit.
Which device allows for piping misalignment and isolation?
  • A. D
  • B. C
  • C. B
  • D. A
Answer: A
Explanation:
Understanding the Diagram
The image shows a pump installation detail with various vibration and alignment control devices:
* A - Typically a pipe hanger or suspension support to reduce strain on piping.
* B - Likely a flexible electrical conduit (for pump motor connection).
* C - Spring vibration isolators under the pump base to prevent vibration transmission into the building structure.
* D - A flexible pipe connector (also called a flex connector or braided flexible coupling).
Purpose of Flexible Pipe Connectors
Flexible pipe connectors (D in the diagram) are designed to:
* Absorb minor misalignment between connected piping systems.
* Reduce stress on pump flanges due to thermal expansion, settlement, or installation tolerances.
* Isolate vibration from the pump so that it is not transmitted along rigid piping to the building structure.
This makes them essential in mechanical systems where pumps, chillers, or other vibrating equipment connect to rigid building piping.
Why Other Options Are Incorrect:
* A. Pipe hangers/supports - Maintain alignment and support vertical loads but do not allow for misalignment or vibration isolation in the same way as flexible connectors.
* B. Electrical conduit/flexible connection - Relates to electrical supply flexibility, not piping alignment.
* C. Spring vibration isolators - Isolate vibration from equipment to the floor but do not address piping misalignment.
NCARB ARE 5.0 PDD Study Guide References:
* Content Area: Integration of Building Materials & Systems - Mechanical Systems Coordination
* Source References:
* Mechanical and Electrical Equipment for Buildings (MEEB) - Chapter on Vibration Isolation & Pump Installation
* Architectural Graphic Standards - Flexible Connector & Piping Details
* Key Point: Flexible connectors at pumps and equipment protect against misalignment, vibration, and stress transfer to the piping system.
