Construction Specifications Institute CDT Exam With Confidence Using Practice Dumps

In CSI / CDT usage, quality assurance (QA) and quality control (QC) are distinct concepts:

Quality Assurance (QA) focuses on planning, processes, and preventive actions put in place before and during the work to help ensure the required quality will be achieved. It is about systems and procedures.

Quality Control (QC) focuses on inspection, testing, and verification to determine whether the constructed work conforms to the requirements of the Contract Documents.

Typical examples:

QA examples (process-oriented):

Developing and following a project-specific quality plan.

Coordinating scheduling and sequencing of the work so trades do not interfere with one another and work is done under appropriate conditions.

Prequalification of contractors, subcontractors, and testing agencies.

Establishing and enforcing submittal procedures and preinstallation meetings.

QC examples (inspection/testing):

Field testing (e.g., concrete cylinder tests, soil compaction tests).

Visual inspection of installed work.

Checking that installed products match submittals and specifications.

Looking at the options:

A. Performing compaction testing – This is a field test used to verify densities and is clearly quality control, not QA.

B. Field observations – These are performed by the A/E or others to observe and verify that work appears to be in general conformance; this is quality control.

C. Validating quantities for payment – This is a contract administration / cost control activity, not primarily a quality activity.

D. Scheduling and sequencing of the work – This is planning and coordination done in advance so the project can proceed efficiently, correctly, and without damaging completed work. Because it is a procedure-based, preventive activity, CSI places this type of planning under quality assurance.

Therefore, the example of quality assurance is “Scheduling and sequencing of the work” (Option D).

Comprehensive and Detailed Explanation From Exact Extract (CSI-based)

CSI describes post-occupancy evaluation (POE) as a review of how the completed facility is performing for its users and operations staff, compared to the Owner’s Project Requirements (OPR). For the evaluation to be meaningful:

The facility must have been occupied long enough for systems and spaces to be used under normal operating conditions.

It should happen early enough that findings can inform warranty corrections, adjustments, and future projects.

CSI’s practice guidance indicates that POEs are typically performed several months after initial occupancy, often in the range of three to six months, when occupants have adjusted to the building and operational patterns are established but the project is still within the correction/warranty period. That aligns with Option B.

Why the others are less suitable:

A. At the end of the correction period and C. Just before the end of the warranty period – these are usually around one year; waiting this long reduces the time available to act on findings while warranties are in force.

D. One year after substantial completion – also generally coincides with warranty expiration; by then, significant issues may have already affected operations without being captured early.

In CSI-based drawing conventions, a scaled view is one drawn at a stated scale so that actual dimensions can be measured directly from the drawing (e.g., 1:100, 1/4" = 1'-0"). CSI’s Uniform Drawing System (UDS) treats floor plans, roof plans, and foundation plans as primary orthographic views prepared at a defined scale for dimensioning and coordination between disciplines. These are the standard “working drawings” for construction.

Foundation plan (Option B)A foundation plan is an orthographic plan view drawn to a specific scale showing footings, slabs, and foundations with dimensions and notes. It is intended for measurement and layout, and CSI references it as one of the basic scaled plan views of the project drawings.

Why the other options are not correct:

A. Perspective – Perspectives are pictorial views used for visualization and presentation. CSI notes that such views are typically not used for taking dimensions and may not be drawn to a true working scale.

C. Riser diagram – Riser diagrams (for plumbing, fire protection, electrical, etc.) are diagrammatic, showing relationships and routing, not physical locations at scale. They are expressly identified as “not to scale” in most construction document standards.

D. Isometric – Isometric drawings are a type of pictorial/axonometric view used to show three-dimensional relationships. While they can sometimes be constructed proportionally, CSI’s guidance treats them as diagrammatic/pictorial views rather than the primary scaled working views used for dimensioning work in the field.
