630.03  Certified Drawings.  Furnish certified drawings according to 625.06.  Submit sign support certified drawings that cover all design types such as ground mounted, rigid overhead, span wire mounted, and overpass structure mounted supports.  On the drawings, show overall height, sign clearance above foundation, span length, sign locations, sign overall heights and widths, and glare shield height and location, if applicable.

630.04  Sign Fabrication.  Sign types include flat sheet, double faced, extrusheet, and temporary overlay.  Flat sheet signs consist of one-piece units made of aluminum.  Double faced signs consist of flat sheet aluminum or extruded aluminum blanks with legend on both sides.  Extrusheet signs consist of a number of horizontal panels assembled to form a complete sign.  Temporary overlay signs consist of an aluminum sheet covering portions or entire surfaces of extrusheet signs.

Prior to reflective sheeting application, clean aluminum sign surfaces either by total immersion in a tank containing an alkaline solution of the manufacturer’s specification or by steam cleaning with an alkaline solution of the manufacturer’s specification, followed by a thorough rinsing with running water.  After cleaning, etch the surface with an acid solution, and dry.  Do not allow cleaned and etched surfaces to become contaminated by contact with oil or grease.  Drill or punch bolt holes to finish size.

Use sign legends according to the OMUTCD and the Sign Designs and Markings Manual.  Use Clearview font for positive contrast legends on freeway and expressway guide signs and on all other guide signs when permitted in the Sign Designs and Markings Manual.  For negative contrast legends, use the Standard Alphabets for Traffic Control Devices.  Use capital legends and upper/lower case legends in accordance with the Sign Designs and Markings Manual.  When either is permitted in the Sign Designs and Markings Manual, use upper/lower case legends.

For flat sheet, double faced mile marker, double faced street name and ground mounted extrusheet signs, use Type G, H or J reflective sheeting for background and reflective legends.  For overhead extrusheet signs, use Type G, H or J reflective sheeting for the background, and use Type H or J reflective sheeting for reflective legends, shields and symbols (including hazardous material plaque, airport symbol, arrows and borders). Apply reflective sheeting to the surface according to the manufacturer’s recommendations, with no blisters, wrinkles, tears, or blemishes.  Do not use reboundable or damage control sheeting for permanent signs.

For reflective legends on flat sheet, double faced mile marker and double faced street name signs, use reverse silk screen transparent ink, transparent acrylic electronic cuttable film, or direct applied reflective sheeting copy.  When using direct applied reflective sheeting copy, apply all legend on a sign with the same rotation angle orientation.  For nonreflective legends, use direct silk screen black ink or direct applied nonreflective acrylic opaque black sheeting copy.  For double faced mile marker signs, use flat sheet aluminum and apply reflective sheeting and legend to both sides.  For double faced street name signs, use extruded aluminum blanks with a minimum thickness of 0.063 inch (1.6 mm) and thicker, stiffened edges, and apply reflective sheeting and legend to both sides.

Extrusheet panels consist of flat sheet aluminum reinforced with aluminum extrusions attached by spot welding.  Panels extruded in a single operation may be used in lieu of spot welded  panels.  Do not use extruded panels and spot welded panels in the same sign.  Bolt together the minimum number of full length, sheeted panels to achieve the sign height, using aluminum bolts, washers, lock washers and nuts.  For reflective legends, shields and symbols (including hazardous material plaque, airport symbol, arrows and borders) use direct applied reflective sheeting.  Apply all reflective legend on a sign with the same rotation angle orientation.  For nonreflective legends, use direct applied nonreflective acrylic opaque black   sheeting copy.

For temporary overlay signs, use 0.080-inch (2.0 mm) thick flat sheet aluminum, with a maximum panel size of 8 x 4 feet (2.4 x 1.2 m).  Apply sheeting and legend as described above for extrusheet signs.  Attach temporary overlays to extrusheet signs in the shop or field using aluminum blind rivets at a maximum spacing of 18 inches (0.5 m) on the peripheries of the temporary overlays and 24 inches (0.6 m) within the interior.

Use fluorescent yellow-green reflective sheeting for the following signs and plaques: School (S1-1), School Bus Stop Ahead (S3-1), SCHOOL BUS TURN AHEAD (S3-2), SCHOOL ENTRANCE (S3-H3), SCHOOL (S4-3P), School Speed Limit Ahead (S4-5, S4-5a), yellow portions of School Speed Limit (S5-H1), Pedestrian Crossing (R1-6, R1-6b, R1-9), Bicycle (W11-1), Pedestrian (W11-2), Handicapped (W11-9), Bicycle/Pedestrian (W11-15), Trail Crossing (W11-15a), Playground (W15-1), and SAFETY ZONE (W15-H2).  Fabricate supplemental warning plaques [such as Advisory Speed (W13-1P), SHARE THE ROAD (W16-1P), Distance (W16-2P, W16-2aP, W16-3P, W16-3aP), Supplemental Arrow (W16-5P, W16-6P, W16-7P) and AHEAD (W16-9P)] from fluorescent yellow-green reflective sheeting when used with a sign above.

Use fluorescent yellow reflective sheeting for all yellow signs, yellow portions of multi-colored signs, and yellow sign post reflectors, except for signs and portions of signs required to be fabricated with fluorescent yellow-green reflective sheeting.

For lighted signs, cover glare shield and rectangular luminaire support tube with nonreflective acrylic sheeting matching the predominant sign color.

Furnish 4 x 2.5 inch (100 x 62 mm) sign identification stickers of Type F reflective sheeting as shown in Figure 1.  For signs fabricated in English based sizes, use white stickers with red ink legend.  For signs fabricated in hard metric based sizes, regardless of the sign message units contained on the sign face, use yellow stickers with red ink legend.  Place the stickers on the back side of the sign in the lower right corner of rectangular signs, or in an equivalent location for other sign shapes, approximately 3 inches (75 mm) from side and bottom sign edges (for smaller signs, these dimensions may be reduced).  Position the sticker so it can be read horizontally and is clearly visible, not near bolt holes or rivets, and not obstructed by the sign support when erected.

Silk screen the fabrication data onto the face of the sticker, and include the sheeting manufacturer identification code and year of fabrication.  Alternatively, the numbers 0-1-2-3-4-5-6-7 and 13-14-15-16-17 may be silk screened onto the sticker with the correct sheeting manufacturer identification code and fabrication year punched out, respectively.  At the time of sign erection, indicate the erection data by scratching out the appropriate month and year.
