In construction, "Ditto" is an abbreviation meaning "same as above" or "the same as previously stated." It is a shorthand used in various construction documents to indicate that information in a current entry is identical to the one directly preceding it.
Understanding "Ditto" in Construction Documentation
The term "ditto" serves as a practical tool for conciseness and clarity in complex construction documents such as drawings, specifications, and schedules. Its primary function is to avoid redundant writing when details or specifications are repeated sequentially.
Why "Ditto" is Utilized
The use of "ditto" in construction documentation provides several key benefits:
- Enhances Efficiency: It saves significant time for anyone preparing or reviewing documents, as they don't need to write or read identical information multiple times.
- Saves Space: By eliminating repetitive text, documents become more compact and easier to navigate, especially large tables or lists.
- Reduces Errors: When "ditto" is used, it explicitly communicates that the preceding information is to be copied exactly, minimizing the potential for transcription mistakes that could occur if details were re-entered manually.
- Improves Readability: Documents with fewer redundant details are generally clearer and quicker to interpret.
Practical Applications of "Ditto" in Construction
"Ditto" is commonly found in tabular data and sequential lists across various construction project phases:
-
Material Schedules: In a schedule for doors, windows, or finishes, if several items share the same dimensions, material, or finish, "ditto" can be used in subsequent rows.
-
Example: Window Schedule Excerpt
Item ID Type Size (W x H) Frame Material Glazing Finish W-01 Fixed 48" x 60" Aluminum Double-Pane Black W-02 Fixed Ditto Ditto Ditto Ditto W-03 Casement 36" x 48" Vinyl Double-Pane White
In this example, W-02 shares all specifications with W-01.

-
Bill of Quantities (BOQ) / Cost Estimates: When listing quantities of similar components or tasks, "ditto" may be used in columns like "Description," "Unit," or "Specification" if the details are identical to the line above.
-
Specification Sections: If a specific installation method, quality standard, or product characteristic applies to multiple consecutive items within a specification section, "ditto" can indicate its recurrence.
-
Drawing Notes: While less frequent, "ditto" might appear in notes on architectural or engineering drawings to denote identical dimensions or details where space is limited and repetition is evident.
"Ditto" as a Standard Abbreviation
Understanding "ditto" is part of the broader knowledge of common construction abbreviations essential for clear and efficient communication. Unlike abbreviations like "TYP." (typical), which might apply to non-adjacent, similar instances throughout a project, "ditto" specifically refers to the item immediately above it in a list or table. Proficiency in these conventions is crucial for all construction professionals, from designers and engineers to contractors and tradespeople, ensuring accurate project execution and minimizing misunderstandings.
