Title Blocks

It is standard practice to include a title block on each page of a set of blueprints. It is typically located in the bottom right-hand corner of the drawing frame. Many firms, however, are using customized sheets that extend the title block from the lower right to the upper right-hand side of the sheet (Figure 2.13). The title block should show the name of the project and the drawing and sheet numbers as well as the drawing title (e.g., "site plan"). The drawing number is especially important, both for purposes of filing the blueprint and for locating the correct drawing when it is specified on another blueprint. The title block also typically shows the name of the consultant, architect, engineer, or designer and the signature of the approving authority. The title block should normally show the date the drawing was made and the initials of who made it. This information is important because using an outdated set of drawings can cause serious problems. Any revisions should be noted within the title block.

To summarize, the title block should generally contain the following information:

• Name of the consultant, company, or organization with address and phone number.

• Title of the drawing. This is an identification of the project by client name, company, or project name.

• Drawing number. This can be a specific job or file number for the drawing.

• Scale. Some consultant firms provide a location for the general scale of the drawing in the title block, although most firms now omit the scale from the title block and place it on the sheet directly below the title of each individual plan, view, or detail. Where more than one scale is used, as is found on detail sheets, the space for indication of scale should read "as noted" or "as shown."

• The signature or initials of the drafter, checker, approving officer, and issuing officer, with the respective dates, should be shown.

• Drawing or sheet identification. Each sheet should be numbered in relation to the entire set of drawings. Thus, if the set consists of ten sheets, each consecutive sheet is numbered 1 of 10, 2 of 10, and so on.

• Other information as required.

The following information is also normally required in title blocks: the name and location of the activity, the specifications and contract numbers (if any), the preparing activity including the architect-engineer (A-E) firm if applicable, and the surnames of the personnel concerned in the preparation of the drawings.

Revision Block

Many firms provide a revision column in which drawing changes are identified and recorded. The revision block is usually located in the right-hand comer of the blueprint. All revisions are noted in this block and dated and identified by a letter and an optional brief description of the revision with the initials of the individual making the change (Figure 2.14). If changes are made on the face of the drawing after it has been released for construction, a circle with a revision number or letter should accompany the change.

The graphic representation of the project is drawn to some proportion of the actual size of the project; usually 1/8 inch is equal to a foot.

Although the original drawing may be scaled accurately, the print will be a copy of that original and is not likely to be the same size as the original drawing. The copy may have been reduced slightly. Likewise, the paper size is often affected by temperature and humidity and may therefore stretch or shrink. Due to these and other factors, avoid relying on measurements taken by laying a rule on the drawing.


For large projects, a drawing may sometimes be divided into a grid using letters and numbers. When zoning is used, it is typically located inside the drawing frame. Zoning allows easy reference to various parts of the drawing by referencing a coordinate such as B4.
