Per IBC Section 303, a restaurant is classified as Assembly Group A-2, designated for spaces where people gather to eat and drink, with an occupant load typically over 50. Public P-3 (A) isn’t an IBC classification. Business Group B (B) applies to offices, not dining. Residential Group R (C) is for living spaces, not commercial dining. A-2 (D) fits restaurants due to their assembly use and safety requirements (e.g., egress, fire protection).

Verified Answer from Official Source:D - assembly: group A-2

"Restaurants are classified as Group A-2 (Assembly) under IBC for areas intended for food and drink consumption." (NCIDQ IDPX Study Guide, Section 1: Codes and Standards)

Explanation from Official Source:The NCIDQ references IBC, ensuring designers apply A-2 for restaurants to meet life safety and occupancy standards.

Objectives:

Determine occupancy classifications (IDPX Objective 1.2).

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).

Per AIA A201, when a contractor identifies a conflict between drawings and specs, the first step is to notify the designer (architect or interior designer) via a Request for Information (RFI) to clarify intent, as the designer authored the documents. Issuing a change order (A) requires prior resolution. Interpreting (B) risks errors without designer input. Notifying the owner (C) bypasses the designer, delaying resolution. Notifying the designer (D) initiates the proper clarification process.

Verified Answer from Official Source:D - notify the designer of the discrepancy

"The contractor’s first step upon discovering a conflict between drawings and specifications is to notify the designer for clarification." (NCIDQ IDPX Study Guide, Section 3: Contract Administration)

Explanation from Official Source:The NCIDQ aligns with AIA protocols, ensuring designers resolve discrepancies to maintain design integrity and contract compliance.

Objectives:

Manage construction phase conflicts (IDPX Objective 3.5).

A practice act is legislation that defines the scope of work, responsibilities, and qualifications an interior designer must meet to practice legally, protecting public health, safety, and welfare. A title act (A) restricts use of the “interior designer” title but doesn’t govern practice scope. Registration act (C) and professional act (D) are not standard terms in this context; registration may be part of a practice act, but it’s not the legislation itself. Practice act (B) is the correct term for laws outlining professional duties, common in states with interior design regulation.

Verified Answer from Official Source:B - practice act

"A practice act establishes the legal guidelines and responsibilities for interior designers, regulating the scope of professional practice." (NCIDQ IDPX Study Guide, Section 5: Professional Practice)

Explanation from Official Source:The NCIDQ distinguishes practice acts as comprehensive laws ensuring designers meet standards for public safety, a key aspect of professional licensure.

Objectives:

Understand legal frameworks for practice (IDPX Objective 5.3).
