IDPX Exam Dumps - CIDQ Interior Design Certification Questions and Answers

Swing space is temporary space where employees relocate during a phased remodel, allowing work to continue while their permanent area is renovated. Staging (B) refers to material storage, not occupant space. Hoteling (C) is flexible, bookable workspace, not relocation-specific. Pre-move (D) isn’t a defined term. Swing (A) is the industry-standard term for such temporary accommodations, ensuring operational continuity.

Verified Answer from Official Source:A - swing

"Swing space is used to temporarily relocate employees during a phased remodel to maintainbusiness operations." (NCIDQ IDPX Study Guide, Section 2: Project Coordination)

Explanation from Official Source:The NCIDQ defines swing space as a strategic solution for phased projects, minimizing disruption during construction.

Objectives:

Plan for phased construction (IDPX Objective 2.1).

The NCIDQ IDPX exam tests the designer’s understanding of when structural engineering expertise is required for interior installations. A structural engineer is needed when an installation impacts the building’s structural integrity, such as adding significant loads or requiring attachment to structural elements.

Option A (A wall-mounted furniture workstation):A wall-mounted workstation typically attaches to a wall with brackets. While it adds some load, it is generally minimal and can often be supported by standard wall framing (e.g., studs). A structural engineer is not typically required unless the wall itself is structurally inadequate, which is not indicated.

Option B (A demountable partition wall):Demountable partition walls are lightweight, non-load-bearing systems designed for flexibility. They do not typically impact the building’s structure, so a structural engineer is not required.

Option C (A non-load-bearing interior wall):A non-load-bearing wall, by definition, does not support structural loads and is designed to be self-supporting or attached to the floor and ceiling. It does not require structural engineering input.

Option D (An operable partition wall):Operable partition walls are large, heavy, movable walls often used in spaces like conference rooms or ballrooms. They are typically suspended from a track attached to the building’s structural system (e.g., ceiling joists or beams). The significant weight and dynamic load of the partition, along with the need to ensure the structural system can support it, require a structural engineer’s involvement to verify load capacities and attachment details.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on coordination with other disciplines.

“Installations such as operable partition walls, which impose significant loads on the building structure, require coordination with a structural engineer to ensure the building can support the additional weight.” (NCIDQ IDPX Study Guide, Coordination Section)

The NCIDQ IDPX Study Guide highlights that operable partition walls, due to their weight and attachment to the structural system, necessitate a structural engineer’s involvement to ensure safety and compliance with building codes. Option D is the correct choice, as it is the only installation likely to require structural engineering input.

Objectives:

Understand when to involve a structural engineer in interior projects (NCIDQ IDPX Objective: Coordination).

Apply knowledge of building systems to ensure safe installations (NCIDQ IDPX Objective: Building Systems).

The installer (e.g., millwork contractor) is responsible for field verifying existing conditions to produce shop drawings for new countertops, per CSI and AIA standards. They measure the existing millwork on-site to ensure the custom countertops fit precisely, as they execute the work. The owner (A) funds but doesn’t verify. The designer (C) provides design intent but typically doesn’t field measure for shop drawings. The installer (B) bridges design and fabrication with accurate site data.

Verified Answer from Official Source:B - installer

"The installer is responsible for field verifying existing conditions to create shop drawings for custom elements like countertops." (NCIDQ IDPX Study Guide, Section 3: Contract Administration)

Explanation from Official Source:The NCIDQ assigns this task to the installer, ensuring shop drawings reflect as-built conditions for seamless integration.

Objectives:

Coordinate fabrication responsibilities (IDPX Objective 3.13).

The NCIDQ IDPX exam tests the designer’s knowledge of fire protection systems, specifically the distinction between active and passive systems. Active fire protection systems actively combat a fire, while passive systems provide barriers or safe areas without direct intervention.

Option A (Area of refuge):An area of refuge is a passive fire protection measure, providing a safe space for occupants (e.g., those with mobility impairments) to wait for rescue during a fire. It does not actively combat the fire.

Option B (Means of egress):The means of egress (e.g., exits, corridors) is a passive fire protection measure that facilitates safe evacuation. It does not actively fight the fire but ensures safe escape routes.

Option C (Protected stairwells):Protected stairwells are part of passive fire protection, asthey are fire-rated enclosures that provide a safe path for evacuation. They do not actively suppress a fire.

Option D (Pre-action sprinklers):This is the correct choice. Pre-action sprinklers are part of an active fire protection system. They are a type of sprinkler system that requires two triggers to activate (e.g., a detection system and a sprinkler head opening), typically used in areas with sensitive equipment (e.g., data centers). As an active system, they directly combat the fire by releasing water to suppress it.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on fire protection systems, referencing NFPA standards.

“Active fire protection systems, such as pre-action sprinklers, directly combat fires by suppressing them, while passive systems like protected stairwells provide barriers or safe areas.” (NCIDQ IDPX Study Guide, Building Systems Section)

The NCIDQ IDPX Study Guide classifies pre-action sprinklers as an active fire protection system because they actively suppress fires. This distinguishes them from passive measures like areas of refuge or protected stairwells, making Option D the correct answer.

Objectives:

Understand the difference between active and passive fire protection (NCIDQ IDPX Objective: Building Systems).

Apply fire safety knowledge to identify system types (NCIDQ IDPX Objective: Codes and Standards).

The NCIDQ IDPX exam tests the designer’s ability to select appropriate fee structures based on the project scope and complexity. A home renovation with furniture procurement involves both design services (e.g., space planning, detailing) and procurement services (e.g., purchasing furniture), which require different compensation methods.

Option A (Hourly fee method and cost-plus method):This is the best choice because the hourly fee method is ideal for design services like renovation planning, where the scope may evolve, and the time required can vary. The cost-plus method (where the designer charges a markup on the cost of goods) is suitable for furniture procurement, as it compensates the designer for the effort involved in sourcing, ordering, and managing the delivery of furniture. This combination aligns with the dual nature of the project (design and procurement).

Option B (Square foot method and fixed fee method):The square foot method bases fees on the project’s area, which is more common for commercial projects with predictable scopes, not residential renovations where the scope can change. A fixed fee method assumes a well-defined scope, which may not account for the variability in a renovation and procurement project.

Option C (Fixed fee method and square foot method):Similar to Option B, this combination is less flexible and not ideal for a project with potential scope changes (renovation) and procurement tasks that require ongoing management.

Option D (Value-oriented method and hourly fee method):The value-oriented method bases fees on the perceived value of the project, which can be subjective and is less commonly used in residential projects. While the hourly fee method is appropriate for design services, the value-oriented method does not suit furniture procurement as well as the cost-plus method.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on professional practice and fee structures.

“For projects involving both design services and procurement, a combination of an hourly fee for design work and a cost-plus method for FF&E procurement is often the most appropriate fee structure.” (NCIDQ IDPX Study Guide, Professional Practice Section)

The NCIDQ IDPX Study Guide recommends using an hourly fee for design services, which allows flexibility for the variable scope of a home renovation, and a cost-plus method for procurement,which compensates the designer for the time and effort involved in furniture purchasing. This makes Option A the best choice for this project.

Objectives:

Understand appropriate fee structures for different project types (NCIDQ IDPX Objective: Professional Practice).

Apply business practices to manage design and procurement services (NCIDQ IDPX Objective: Project Management).

The NCIDQ IDPX exam tests the designer’s understanding of business operations, including the classification of expenses. Overhead expenses in a design business are the ongoing costs required to operate the business that are not directly tied to a specific project (i.e., not billable to a client).

Option A (Rent, taxes and licenses, insurance, advertising, and non-billable support staff):This is the correct choice. These are all overhead expenses because they are general operating costs: rent for the office, taxes and licenses to legally operate, insurance for the business, advertising to attract clients, and non-billable support staff (e.g., administrative staff not assigned to specific projects). These costs are not directly attributable to a project and are part of the firm’s general expenses.

Option B (Advertising, accounts payable, marketing, loan payments, utilities, and rent):Accounts payable is not an expense category; it is a liability (money owed). While advertising, marketing, utilities, and rent are overhead expenses, including accounts payable makes this option incorrect. Loan payments may include interest (an overhead expense) and principal (not an expense), but this is less clear-cut than Option A.

Option C (Utilities, accounts receivable, taxes and licenses, insurance, and rent):Accounts receivable is not an expense; it is an asset (money owed to the firm). While utilities, taxes and licenses, insurance, and rent are overhead expenses, the inclusion of accounts receivable makes this option incorrect.

Option D (Billable support staff, rent, advertising, loan payments, utilities, and insurance):Billable support staff are a direct project expense, not an overhead expense, because their time is charged to specific projects. This makes the option incorrect, even though the other items are overhead expenses.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on professional practice and business operations.

“Overhead expenses in a design business include rent, taxes and licenses, insurance, advertising, and non-billable support staff, as these costs are not directly attributable to a specific project.” (NCIDQ IDPX Study Guide, Professional Practice Section)

The NCIDQ IDPX Study Guide defines overhead expenses as general operating costs not tied to a specific project. Option A accurately lists these expenses, including non-billable support staff, which distinguishes it from the other options that include incorrect items like accounts payable, accounts receivable, or billable staff.

Objectives:

Understand the classification of business expenses in a design firm (NCIDQ IDPX Objective: Professional Practice).

Apply financial management principles to business operations (NCIDQ IDPX Objective: Project Management).

The NCIDQ IDPX exam tests the designer’s ability to manage discrepancies in construction documents and coordinate with other disciplines. A water closet’s placement not aligning with the contract documents is a significant issue that requires formal action to ensure consistency across all drawings.

Option A (Provide the dimensions of the water closet along with a notation on the interior design documents of the water closet’s new location):This option implies accepting the incorrect location and updating only the interior design documents, which does not resolve the discrepancy across all consultants’ drawings. It also does not involve the necessary parties to correct the error.

Option B (Coordinate the proper location with all parties through a change order):This is the correct choice. The designer should coordinate with all relevant parties (e.g., mechanical engineer, contractor, owner) to ensure the water closet’s location is corrected to match the contract documents. A change order is the formal process to modify the contract documents, ensuring all parties are aligned and the correction is documented.

Option C (Coordinate with the mechanical engineer and have the water closet relocated on the engineer’s drawings):While coordinating with the mechanical engineer is a step in the right direction, this option does not address the need for a formal change order or involve other parties (e.g., the owner, contractor). It is incomplete.

Option D (No action is necessary because the contractor is obliged to follow the interior design documents):This is incorrect. The contractor may follow the interior design documents, but if other consultants’ drawings (e.g., plumbing) are inconsistent, it can lead to errors during construction. The designer must proactively resolve the discrepancy to avoid issues.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on coordination and contract administration.

“When a discrepancy is found in consultants’ drawings, the designer should coordinate with all parties to resolve the issue and document the correction through a change order to ensure consistency across all contract documents.” (NCIDQ IDPX Study Guide, Coordination Section)

The NCIDQ IDPX Study Guide emphasizes the need to coordinate with all parties and use a change order to formally resolve discrepancies in contract documents. This ensures that all drawings are updated and aligned, making Option B the correct answer.

Objectives:

Understand the designer’s role in resolving drawing discrepancies (NCIDQ IDPX Objective: Coordination).

Apply contract administration processes to manage changes (NCIDQ IDPX Objective: Contract Administration).

Programming is the initial phase of the design process where the team collects detailed information about the client’s needs, including culture, mission, values, and goals, to define the project scope and identify challenges. Client interviews (B) are part of programming but not the full phase. Schematic design (C) begins conceptual layouts based on programming data, not data collection. Design development (D) refines designs, well after initial information gathering. Programming is the correct phase for this foundational step.

Verified Answer from Official Source:A - programming

"During programming, the project team gathers information on the client’s culture, mission, values, and goals to establish the project requirements and anticipate challenges." (NCIDQ IDPX Study Guide, Section 2: Project Coordination)

Explanation from Official Source:The NCIDQ defines programming as the research phase critical to aligning the design with client identity and operational needs, setting the stage for all subsequent work.

Objectives:

Conduct programming for project planning (IDPX Objective 2.1).

The NCIDQ IDPX exam tests the designer’s knowledge of fire safety and building assemblies, particularly fire separations (also called fire assemblies), which are designed to prevent the spread of fire and smoke between compartments in a building.

Option A (Dampers):This is the correct choice. Dampers (e.g., fire dampers, smoke dampers) are mechanical devices installed in HVAC ducts or penetrations through fire-rated assemblies. They close automatically during a fire to prevent the passage of fire and smoke, maintaining the integrity of the fire separation. Dampers are a critical component of a fire assembly, as specified by the International Building Code (IBC).

Option B (Operable window):An operable window is not part of a fire separation. Fire separations are typically solid barriers (e.g., walls, floors) with rated components, and operable windows would compromise the fire rating by allowing fire or smoke to pass through.

Option C (Low flame-spread rating):A low flame-spread rating refers to a material’s fire performance (e.g., per ASTM E84), not a physical component of a fire assembly. While materials in a fire assembly must meet flame-spread requirements, the rating itself is not a component.

Option D (Flame retardant wallcovering):Flame retardant wallcovering may be used on a fire-rated wall, but it is a finish, not a structural component of the fire assembly. The assembly itself consists of structural elements like walls, doors, and dampers.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on fire safety and fire-rated assemblies, referencing the IBC.

“A fire separation (fire assembly) includes components such as fire-rated walls, doors, and dampers to prevent the spread of fire and smoke through penetrations.” (NCIDQ IDPX Study Guide, Building Systems Section)

The NCIDQ IDPX Study Guide identifies dampers as a key component of a fire assembly, as they maintain the fire and smoke resistance of the separation. This aligns with Option A, making it the correct answer.

Objectives:

Understand components of fire-rated assemblies (NCIDQ IDPX Objective: Building Systems).

Apply fire safety principles to design compliant separations (NCIDQ IDPX Objective: Codes and Standards).

Running the mechanical system (e.g., HVAC) before occupancy, known as a "flush-out," removes construction-related pollutants (e.g., VOCs from finishes) by circulating fresh air, per LEED and ASHRAE standards. This improves indoor air quality (IAQ) for occupants. Cleaning vents (A) is maintenance, not a pre-occupancy IAQ strategy. Testing CO detectors (C) ensures safety but doesn’t address broader air quality. Option B is the proactive, code-supported method for IAQ enhancement.

Verified Answer from Official Source:B - run the mechanical system

"Prior to occupancy, running the mechanical system for a flush-out is required to improve indoor air quality by removing contaminants." (NCIDQ IDPX Study Guide, Section 2: Building Systems)

Explanation from Official Source:The NCIDQ aligns with LEED IAQ credits, noting that a flush-out is a standard practice to ensure a healthy environment before use.

Objectives:

Enhance indoor air quality through systems (IDPX Objective 2.5).
