Graphic Guidelines

Drafters and engineers should keep in mind that the ultimate products of their work are the 11" x 17" prints made from their drawings. The standards and guidelines given in this manual are intended to improve print quality and readability.

Besides using recommended line weights, scales, and the Bridge Division’s customized font, individual printers must be adjusted to closely match the line weights on hardcopies made from Bridge Division printers. Issued standards on 11" x 17" paper may be used as an aid in establishing acceptable line weights or, upon request, 11" x 17" paper examples will be provided.

Standard Scales

Standard drafting scales (either engineering or architectural) shall be used when creating a detail sheet so the details on the final, contract, or construction plans are measurable. This requirement does not imply that prints of detail sheets should be measured in the field to establish construction dimensions. The drawing accuracy is intended only to assist in eliminating constructibility and dimensioning errors. The dimensions presented in the details shall control all construction.

Abbreviations

To save space, do not use a period after commonly abbreviated words such as max, min, typ, spa, etc. Use a period only after abbreviations that spell a word, such as no., and abbreviations that are not commonly recognized.

Symbol Reference

When using more than one or two symbols, use circles with numbers

Line Weights

The following listed line weights shall be used in the Bridge Division for structural detailing. Small or delicate details may require using smaller line weights for clarity.

Dimensions

Generally, construction dimensions are shown in feet and inches. Decimals of a foot should be used where dimensions are being set by surveying equipment, such as beam spacing, foundation locations, and structure widths in plan views on detail sheets.

Commas

Use commas to separate blocks of three digits or any number with four or more digits.
