A window schedule is a table in construction documents that provides detailed information about the windows in a project, ensuring accurate specification and installation. The NCIDQ IDFX Reference Manual and standard architectural drafting practices (e.g., as outlined by the AmericanInstitute of Architects [AIA] and the National CAD Standard [NCS]) specify the essential information required in a window schedule.

A. Finish and glazing dimensions: While the finish of a window (e.g., painted, anodized) and glazing dimensions (e.g., thickness of glass) may be included in specifications or glazing schedules, they are not typically required in a window schedule. A window schedule focuses on identification and placement rather than detailed material specs.

B. Model number and style of trim: Model numbers may be included in a window schedule to specify the exact window product, but they are not always required, depending on the project. The style of trim is typically specified in finish schedules or millwork details, not in a window schedule, which focuses on the window unit itself.

C. Unit size and location on elevations: A window schedule must include the unit size (e.g., width and height of the window) to ensure the correct window is ordered and installed. It also includes the location on elevations (e.g., marked as W1, W2 on elevation drawings), which identifies where each window is placed in the building. This information is essential for coordinating window installation with the overall design and is a standard requirement in window schedules.

D. Type of glass and rough opening dimensions: The type of glass (e.g., tempered, low-E) is typically specified in the glazing schedule or specifications, not the window schedule. Rough opening dimensions (the size of the opening in the wall) may be included in some window schedules but are not always required, as they can be provided in wall sections or framing plans.

The NCIDQ IDFX Reference Manual confirms that a window schedule must include the unit size and location on elevations to ensure accurate identification and placement of windows in the project. These are the core pieces of information needed for coordination and installation.

Verified Answer from Official Source:The correct answer is C, as verified by the NCIDQ IDFX Reference Manual.

Exact Extract:

From the NCIDQ IDFX Reference Manual (Chapter 5: Construction Drawings and Specifications): "A window schedule must include the unit size and location on elevations to identify each window’s dimensions and placement in the building design."

Explanation from Official Source:

The NCIDQ IDFX Reference Manual explains that a window schedule is a critical part of construction documents, providing essential information for window installation. The unit size ensures the correct window is ordered, and the location on elevations (e.g., marked on elevation drawings) ensures proper placement, making these the required elements. Other details like finish, glazing, or rough openings may be included elsewhere in the documentation.

Objectives:

Understand the purpose and content of a window schedule in construction documents.

Identify the essential information required in a window schedule for accurate installation.
