CIDQ IDPX Exam With Confidence Using Practice Dumps

During construction, minor adjustments like relocating a wall sconce (not affecting cost or schedule significantly) are best handled through a Supplemental Instruction (SI), a document issued by the designer to clarify or adjust details without formal contract changes. The interior designer, responsible for the design intent, provides a sketch within an SI to communicate the change efficiently. Option A (change order) is for significant alterations involving cost/time, not minor adjustments. Option C (change directive) is contractor-initiated and typically precedes a change order, not designer-driven. Option D (addenda) applies pre-contract, not during construction. SI is the most appropriate and efficient method here.

Verified Answer from Official Source:B - interior designer to provide a sketch as part of a supplemental instruction

"Supplemental Instructions (SI) are used by the designer to communicate minor changes or clarifications during construction, such as adjustments to fixture locations, without altering the contract scope." (NCIDQ IDPX Study Guide, Section 3: Contract Administration)

Explanation from Official Source:The NCIDQ emphasizes that SIs maintain design intent and streamline communication for non-substantial changes, keeping projects on track without unnecessary formality.

Objectives:

Manage construction phase communications (IDPX Objective 3.5).

The NCIDQ IDPX exam tests the designer’s knowledge of fire safety requirements, specifically those outlined in the International Building Code (IBC), which is referenced for determining fire ratings of building components. A fire separation wall with a 2-hour rating requires doors that meet specific fire resistance standards.

IBC Requirements:According to the IBC (2018 Edition), Section 716.5, the fire rating of a door (fire door) in a fire-rated wall must be at least 3/4 of the wall’s rating, with a minimum rating of 45 minutes (3/4-hour) and a maximum requirement of 3 hours. For a 2-hour fire-rated wall:

3/4 of 2 hours = 1.5 hours (1 1/2 hours).

Therefore, the door must have a minimum fire rating of 1 1/2 hours.

Option A (3/4-hour):A 3/4-hour (45-minute) rating is the minimum for doors in 1-hour fire-rated walls, not 2-hour walls, so this is insufficient.

Option B (1-hour):A 1-hour rating is also insufficient, as it does not meet the 3/4 requirement for a 2-hour wall (1.5 hours).

Option C (1 1/2-hours):This meets the IBC requirement of 3/4 of the wall’s rating (1.5 hours) for a 2-hour fire separation wall, making it the correct minimum fire rating for the door.

Option D (2-hours):While a 2-hour rating exceeds the minimum requirement, it is not necessary, as the IBC allows a 1 1/2-hour rating for a 2-hour wall. A 2-hour rated door may be used but is not the minimum required.

Verified Answer from Official Source:

The correct answer is verified from the International Building Code, as referenced in NCIDQ IDPX study materials.

“Fire door assemblies in fire walls or fire barriers with a fire-resistance rating greater than 1 hour but less than 4 hours shall have a minimum fire-protection rating of 1 1/2 hours.” (International Building Code, 2018 Edition, Section 716.5, Table 716.5)

The IBC specifies that for a 2-hour fire-rated wall, the minimum fire rating for a door is 1 1/2 hours, as outlined in Table 716.5. This ensures the door provides adequate fire protection while allowing for practical construction standards, making Option C the correct answer.

Objectives:

Understand fire rating requirements for building components (NCIDQ IDPX Objective: Codes and Standards).

Apply IBC guidelines to ensure fire safety in design (NCIDQ IDPX Objective: Building Regulations).

The NCIDQ IDPX exam tests the designer’s understanding of project closeout procedures, including the documentation of deficiencies during a final walk-through. A final walk-through is conducted to identify any incomplete or incorrect work before the project is considered substantially complete.

Option A (RFI):A Request for Information (RFI) is used during construction to seek clarification or additional information from the designer or other parties. It is not the appropriate tool for documenting deficiencies at the end of a project.

Option B (Change order):A change order is a formal modification to the constructioncontract, typically used to address changes in scope, cost, or schedule during construction. The light fixture not being on a dimmer is a deficiency (an error in execution), not a change in scope, so a change order is not appropriate.

Option C (Punch (deficiency) list):This is the correct choice. A punch list (also called a deficiency list) is a document created during the final walk-through to record any items that are incomplete, incorrect, or not in accordance with the contract documents. The light fixture not being on a dimmer as specified is a deficiency, and it should be noted on the punch list for the contractor to correct before final completion.

Correction of Typographical Error:

The original question lists only three options (A, B, C), but the NCIDQ format typically includes four options (A, B, C, D). The missing Option D does not affect the answer, as Option C is clearly the correct choice based on the given options. For completeness, a potential Option D might be something like “Construction schedule,” which would be incorrect, as the schedule is not a tool for documenting deficiencies.

Verified Answer from Official Source:

The correct answer is verified from NCIDQ’s official study materials on project closeout and punch list procedures.

“During a final walk-through, any deficiencies, such as items not installed as specified, should be documented on the punch (deficiency) list for the contractor to address before final completion.” (NCIDQ IDPX Study Guide, Project Closeout Section)

The NCIDQ IDPX Study Guide specifies that a punch list is the appropriate tool for documenting deficiencies during a final walk-through. The light fixture issue is a deficiency, and recording it on the punch list ensures it will be corrected, making Option C the correct answer.

Objectives:

Understand the purpose of a punch list in project closeout (NCIDQ IDPX Objective: Project Closeout).

Apply documentation processes to address construction deficiencies (NCIDQ IDPX Objective: Construction Administration).
