Specifications: General Conditions (cont'd)

B.2a Rev. 1

All typesetting shall comply to standards for the use of Helvetica Regular, Helvetica Medium, and HelVetica Bold, as described in Appendix D of this manual.

Color, typographic and Corps identifi cation graphics shall conform to the standards as outlined in Section 4 and as shown on the layout drawing for each specific sign panel. No modifica tion shall be permitted. Horizontal and vertical alignment of legends shall not deviate +.0625". Camera-ready full-size artwork of the Corps signature shall be provided by the Corps of Engineers (see page 4.4-9). No modifications shall be permitted.

The following criteria have been used as the standards governing material specifi cation, assembly and footings for aU recreation project signs, unless other wise specified.

Wind Pressure Soil Frost Depth

35 PSF

2-KSF-Minimum 48" Maximum

If these criteria are not adequate for a specific sign location, necessary modifi cation shall be made to conform to the basic assembly specifications of specified sign type. Modifications may include, but are not limited to thicker panels, larger dimension sign posts or larger footing configuration.

The design of the structural require ments of special one-of-a-kind signs shall conform to the basic assembly specifications for similar sign types.

The modified assembly shall fulfill the requirements of local criteria for wind pressure, soil and frost depth.

Assembly configurations and material specifications are referenced under ~'specification code" with sign descrip tions in Sections 5-18. Detailed material, assembly,, and mounting specifications are provided on the next pages.

The following materials shall be used for the construction of signs unless special panels and/or modifications require more stringent standards of performance:

Sign posts for routed redwood signs shall use construction heart redwood per grading rules of the California Redwood Association, or better.

Posts for signs with the HDO or ALU specification codes may use construction heart redwood per grading rules of the California Redwood Association or bet ter, treated Douglas fir No.1 or better, or treated southern yellow pine No.1 or better, unless otherwise specified.

All artwork shall be reproduced using first generation images, as provided in this manual. Reproduction shall be per formed using a distortion-free photo mechanical process or a digitizing sys tem with a pointing accuracy of 1/1 00" (1/25mm) or better. Plotter systems shall have a resolution and positioning accu racy of 1/50mm or better.

All retro-reflective graphics shall be produced in complete one-piece make up, not in individual sections. Lettering up to 45" high shall be produced pre spaced in one piece. Larger lettering and graphics must be prepared pre spaced in exact registration to abutting sections.

Do not use treated posts on signs with routed redwood panels.

Material shall be well seasoned and free of any defects. All post sizes may be no more than 0.5" less than nominal dimensions, and will be sanded smooth prior to finishing.

Break-away or frangible post A large dimension wooden post on approach roadways or project roadways may require break-away or frangible posts. These are used only for signs placed within the highway right-of-way.

Break-away capacity is created by drilling holes parallel to the face of the sign ne_ar the base of the upright. The number, size, and location of holes will be determined based upon size of upright, type of wood, size and height of sign panel, and location of the sign.

Because of the wide variation in struc tural capacity of different fypes of wood, standard specifications are not provided.

Local engineering requirements vary greatly from one jurisdiction to another.

It is recommended that state or local highway engineering design criteria pre vail when placing a sign requiring this feature.

Sign panels shall use HDO plywood, (0.75" thick unless otherwise instructed), or redwood (clear heart, 2" thick).

Alternate material includes sheet alu minum (0.080-0.125"), with appropriate reinforcements as specified on page B.2c.

Footing shall consist of concrete 2500 PSI (28 days). Dimensions shall be as indicated on page B.2b.

The recommended footing size and depth for all signs except directional signs (see page B.2c) as specified in the two right columns of the diagram below, will depend upon the criteria listed in the six columns on the left. The decision to pro vide concrete footings tor signs should be based upon site conditions and post size.
