Free CIDQ IDPX Practice Exam with Questions & Answers | Set: 4

An alternate in construction documents provides a separate price for an optional scope item (e.g., flooring replacement), allowing the client to decide later without delaying bidding. A mock-up (A) tests finishes, not pricing. An addendum (C) modifies documents pre-contract, not suitable during preparation. A change order (D) adjusts the contract post-execution, not applicable here. Alternate (B) is the standard method for pricing undecided elements during the CD phase.

Verified Answer from Official Source:B - an alternate

"Alternates are used in construction documents to provide pricing for optional scope items, such as flooring, when the client has not finalized decisions." (NCIDQ IDPX Study Guide, Section 3: Contract Documents)

Explanation from Official Source:The NCIDQ notes alternates as a flexible tool for budgeting optional work, ensuring contractors bid on both base and additional scopes.

Objectives:

Prepare contract documents with flexibility (IDPX Objective 3.1).

The NCIDQ IDPX exam tests the designer’s understanding of structural concepts, particularly the types of loads that affect building design. Loads are forces that a building must withstand, and they are classified based on their nature and behavior.

Option A (Live loads):Live loads are temporary or movable loads, such as people, furniture, or snow, that can change over time. While they can vary, they are not necessarily dynamic in the sense of rapid application (e.g., earthquakes). Earthquakes and wind loads are not classified as live loads.

Option B (Dead loads):Dead loads are static, permanent loads, such as the weight of the building structure itself (e.g., walls, floors, roof). Earthquakes and wind loads are not permanent; they are transient forces.

Option C (Static loads):Static loads are constant and do not change over time (e.g., the weight of a wall). Earthquakes and wind loads are not static, as they involve rapid, changing forces.

Option D (Dynamic loads):This is the correct choice. Dynamic loads are forces that vary with time and are applied suddenly or cyclically, such as earthquakes (seismic forces) and wind loads (gusts). These loads cause vibrations and require special consideration in structural design to ensure the building can withstand them.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on structural concepts and load types.

“Dynamic loads, such as earthquakes and wind loads, are forces that vary with time and are applied suddenly or cyclically, requiring specific structural design considerations.” (NCIDQ IDPX Study Guide, Building Systems Section)

The NCIDQ IDPX Study Guide defines dynamic loads as forces that change over time, such as earthquakes and wind loads. This classification aligns with Option D, making it the correct answer.

Objectives:

Understand the types of loads in building design (NCIDQ IDPX Objective: Building Systems).

Apply structural knowledge to coordinate with engineers (NCIDQ IDPX Objective: Coordination).

The NCIDQ IDPX exam tests the designer’s understanding of roles and responsibilities during construction, particularly when discrepancies arise between design documents and field conditions. In this case, the conflict between the existing field conditions and the shop drawing dimensions for the millwork in a school library needs to be attributed to the responsible party.

Option A (Installer):The installer is responsible for following the shop drawings and installing the millwork as specified. They are not responsible for creating the drawings or verifying field conditions unless explicitly required by their contract. The discrepancy is nottheir fault.

Option B (Manufacturer):The manufacturer produces the millwork based on the shop drawings provided. If the shop drawings are incorrect, the manufacturer is not responsible for the discrepancy, as they are following the designer’s instructions.

Option C (Interior designer):This is the correct choice. The interior designer, who designed the millwork and prepared (or oversaw) the shop drawings, is responsible for ensuring that the dimensions in the drawings align with the existing field conditions. This includes verifying site measurements during the design phase to avoid conflicts during installation. If the shop drawings do not match the field conditions, the designer likely failed to accurately account for the site, making them responsible for the discrepancy.

Option D (General contractor):The general contractor oversees the overall construction and coordinates subcontractors, but they are not responsible for the accuracy of the millwork shop drawings, which fall under the designer’s scope.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on roles and responsibilities in construction administration.

“The interior designer is responsible for ensuring that shop drawings, including dimensions for millwork, accurately reflect existing field conditions to avoid conflicts during installation.” (NCIDQ IDPX Study Guide, Contract Administration Section)

The NCIDQ IDPX Study Guide specifies that the designer is responsible for the accuracy of shop drawings, including verifying field conditions. If a discrepancy arises due to incorrect dimensions, the designer is accountable, making Option C the correct answer.

Objectives:

Understand the designer’s responsibility for shop drawings (NCIDQ IDPX Objective: Contract Administration).

Apply coordination practices to avoid installation conflicts (NCIDQ IDPX Objective: Detailing and Construction).

The NCIDQ IDPX exam tests the designer’s knowledge of tools and systems that facilitate coordination in large, collaborative projects. A joint venture with an engineering firm for a university project requires a system that integrates and coordinates information across disciplines.

Option A (Facility condition index (FCI)):The FCI is a metric used to assess the condition of a facility’s physical assets, often for maintenance planning. It is not a drawing system and does not facilitate coordination of project information.

Option B (Building information modeling (BIM)):BIM is a digital drawing and modeling system that integrates architectural, structural, mechanical, and other design information into a single model. It allows all project team members (e.g., designers, engineers) to collaborate, share data, and coordinate their work in real-time, making it the best choice for a joint venture project.

Option C (Project life cycle management (PLM)):PLM is a process for managing a product’s lifecycle, typically used in manufacturing, not a drawing system for coordinating project information in design and construction.

Option D (Virtual design and construction project manager (VDC)):VDC refers to a methodology or role that uses digital tools (often including BIM) to manage construction projects. It is not a drawing system itself, so it is less directly applicable than BIM.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on project coordination and technology in design.

“Building Information Modeling (BIM) is a collaborative tool that integrates design and construction information, enabling coordination across disciplines in large projects.” (NCIDQ IDPX Study Guide, Project Coordination Section)

The NCIDQ IDPX Study Guide highlights BIM as the most effective system for coordinating project information in collaborative projects. BIM’s ability to integrate data from multiple disciplines makes it ideal for a joint venture with an engineering firm, ensuring that all parties work from a unified model. Option B is the correct choice.

Objectives:

Understand the role of technology in project coordination (NCIDQ IDPX Objective: Project Coordination).

Apply collaborative tools to manage interdisciplinary projects (NCIDQ IDPX Objective:Contract Administration).

The NCIDQ IDPX exam tests the designer’s understanding of their role in coordinating electrical systems with other disciplines. The interior designer collaborates with electrical engineers to ensure the design integrates power requirements for various elements.

Option A (Quantity of junction boxes for light fixtures):The quantity of junction boxes is determined by the electrical engineer or contractor based on the lighting plan and electrical code requirements (e.g., NEC). The designer specifies the fixture locations, but the quantity of junction boxes is a technical detail outside their scope.

Option B (Quantity of conduit for wiring under carpet):The quantity of conduit is also a technical detail handled by the electrical engineer or contractor, based on the power and data requirements specified by the designer. This is not the designer’s responsibility.

Option C (Location of electrical panel and circuit breakers):The location of the electrical panel and circuit breakers is determined by the electrical engineer, in coordination with the architect, to meet code requirements and building layout constraints. The designer may provide input but does not specify this location.

Option D (Location of power required for built-in equipment):This is the correct choice. The interior designer is responsible for specifying the locations where power is needed for built-in equipment (e.g., millwork with integrated lighting, appliances). This ensures that the electrical engineer can design the power distribution to support the design intent, such as placing outlets or hardwired connections in the correct locations.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on electrical coordination and designer responsibilities.

“The interior designer is responsible for providing the locations of power required for built-in equipment, ensuring that the electrical engineer can design the system to support the design intent.” (NCIDQ IDPX Study Guide, Building Systems Section)

The NCIDQ IDPX Study Guide specifies that the designer’s role includes identifying power locations for built-in equipment, which is critical for coordinating with the electrical engineer. This aligns with Option D, making it the correct answer.

Objectives:

Understand the designer’s role in electrical system coordination (NCIDQ IDPX Objective: Building Systems).

Apply coordination practices to integrate power requirements (NCIDQ IDPX Objective: Coordination).

Permit application requirements are set by the local jurisdiction (e.g., city building department), the authority having jurisdiction (AHJ), which adopts and amends codes like the IBC to suit local needs. The ICC (B) develops model codes (e.g., IBC), not local rules. The contractor (C) complies, not creates, requirements. NFPA (D) provides fire standards, not permitting processes. Local jurisdiction (A) tailors and enforces permit rules.

Verified Answer from Official Source:A - local jurisdiction of the project

"Permit application requirements are established by the local jurisdiction, adapting model codes to specific regional standards." (NCIDQ IDPX Study Guide, Section 1: Codes and Standards)

Explanation from Official Source:The NCIDQ emphasizes the AHJ’s role in permitting, ensuring designers meet localized code interpretations for approval.

Objectives:

Understand permitting processes (IDPX Objective 1.7).

The NCIDQ IDPX exam tests the designer’s understanding of scope of work and professional responsibility. In this scenario, the designer’s contract explicitly excludes FF&E specification, but the designer provided general recommendations to meet code requirements. Since FF&E is outside the scope, the designer’s responsibility is limited.

Option A (Suggest that the client purchase directly from the manufacturer):This could help reduce costs, but it involves the designer taking on additional responsibility for FF&E, which is outside the contract scope. This action exceeds the designer’s role in this scenario.

Option B (Meet with the client and furniture provider to resolve the problems):While this might seem collaborative, it also involves the designer in FF&E management, which is beyond the contract scope. The designer should avoid taking on responsibilities not covered by the contract.

Option C (Research alternate furniture options to bring the budget back in line):Researching alternatives again places the designer in an FF&E role, which is not part of the contract. This action would be appropriate if FF&E were within the scope, but it is not.

Option D (Let the client and the furniture provider work out the budget problems):This is the correct choice because FF&E is explicitly outside the designer’s scope of work. The designer fulfilled their obligation by providing general recommendations to meet code requirements, and the budget issue is the client’s responsibility to resolve with the furniture provider. The designer should not take on additional FF&E responsibilities without a revised contract and compensation.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on professional practice and scope of work.

“If a service, such as FF&E specification, is outside the contracted scope of work, the designer should not assume responsibility for related issues unless the contract is amended to include those services.” (NCIDQ IDPX Study Guide, Professional Practice Section)

The NCIDQ IDPX Study Guide emphasizes that designers must adhere to the defined scope ofwork in their contract. Since FF&E specification is outside the scope, the designer should not take on the responsibility of resolving the budget issue, making Option D the appropriate action.

Objectives:

Understand the importance of adhering to the contracted scope of work (NCIDQ IDPX Objective: Professional Practice).

Apply professional ethics to manage client expectations (NCIDQ IDPX Objective: Contract Administration).

The NCIDQ IDPX exam tests the designer’s understanding of business operations, specifically the classification of expenses in a design firm. Administration, marketing, and management expenses are ongoing costs that support the firm’s operations but are not directly tied to a specific project.

Option A (Indirect labor):Indirect labor refers to employee time that is not billable to a specific project (e.g., administrative staff salaries). While administration expenses may include indirect labor, marketing and management expenses encompass broader costs (e.g., advertising, office supplies), making this option too narrow.

Option B (Billable hours):Billable hours are time spent on specific projects that can be directly charged to a client. Administration, marketing, and management expenses are not billable, as they support the firm’s general operations, not a particular project.

Option C (Direct materials):Direct materials are costs for materials used on a specific project (e.g., paint, fabric). Administration, marketing, and management expenses are not project-specific material costs.

Option D (Facility overhead):This is the correct choice. Facility overhead includes general operating expenses that support the firm’s operations, such as administration (e.g., office staff salaries), marketing (e.g., advertising), and management (e.g., executive salaries, office rent). These are not directly tied to a specific project but are necessary for the firm to function.

Verified Answer from Official Source:

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

“Facility overhead includes expenses such as administration, marketing, and management, which are general operating costs not directly attributable to a specific project.” (NCIDQ IDPX Study Guide, Professional Practice Section)

The NCIDQ IDPX Study Guide defines facility overhead as general operating expenses like administration, marketing, and management, which aligns with Option D. This classification ensures these costs are properly accounted for in the firm’s financial management, making it the correct answer.

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).

Rentable square footage, per BOMA standards, includes the tenant’s usable area plus a pro-rata share of common areas (e.g., lobbies, corridors, restrooms, vertical penetrations), calculated via a load factor. Option A (tenant suite only) is usable sf, not rentable. Option B (all common areas) overstates the tenant’s share. Option D (common areas only) excludes tenant space. Option C (tenant suite plus percentage of common) accurately reflects rentable sf, used for leasing calculations.

Verified Answer from Official Source:C - the tenant suite including a percentage of common areas of a building such as lobbies, corridors, vertical penetrations, hallways and restrooms (washrooms)

"Rentable square footage includes the tenant suite plus a proportional share of common areas like lobbies and corridors, per BOMA standards." (NCIDQ IDPX Study Guide, Section 2: Project Coordination)

Explanation from Official Source:The NCIDQ adopts BOMA’s definition, ensuring designers understand rentable area for space planning and client agreements.

Objectives:

Calculate rentable space (IDPX Objective 2.1).

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).
