Drawings for non -standard message signs shall also show th e arrangement, spacing, font style, and size of all letters, symbols, shields, and borders. This shall include all extruded panel signs.
661.3.3 -Metal Cutting and Preparation: 661.3.3.1 -Cutting: Flat sheet aluminum shall be cut by one of the followin g methods: sheared, blanked, sawed or milled. Extruded Panels shall be sawed or milled. Re -entrant cuts shall be filleted by drilling prior to cutting. No flame cutting will be permitted. Cut edges shall be refinished to present a true and smooth edge that is free from burrs and ragged breaks. Holes shall be made in such a manner as not to affect the finished surface.
661.3.3.2 -Preparation: All cutting, cornering, and punching of aluminum blanks shall be completed prior to final preparation for sheeting application. Before applying retroreflective sheeting, the surface of the material must be totally free of any contamination, dust, residue, loose scale and, in particular, traces of oil, grease or wax. Aluminum blanks should be handled by the edges using clean cotton or canvas gloves. In case of doubt as to cleanliness of the substrate, the substrate shall be tested by methods recommended by t he sheeting manufacturer. Immediately prior to the application of the sheeting, if it is necessary to remove any fingerprints or residue from the blanks, solvent wiping in accordance with the sheeting manufacturer’s recommendations shall be used.
661.3.4-Fabrication of Signs, Reflective Sign Support Strips, and Delineators: 661.3.4.1 -General: Fabrication of all parts shall be in accordance with the dimensions shown on the Plans and approved shop drawings. Work shall be done in a uniform workmanlike manner. Any material permanently adhered over the sign background layer of sheeting, such as another layer of sheeting, ink, or film, shall be a “matched component”, as defined in subsection 715.9.2, of the background layer of sheeting. Sheeting used on demountable legend, border, and shields riveted to extruded panel signs shall not be required to be a matched component of the extruded panel sign background sheeting. However, the material used for all demountable components on each sign shall be the sa me series number of sheeting from a single manufacturer. All materials used shall be materials approved by the Division. All legend, borders, and shields applied to extruded panel signs shall be demountable. All flat sheet signs shall be fabricated us ing inks and/or overlay films. Direct applied reflective legend and border shall not be allowed. Standard message signs displayed within a sign, such as with W3 -1 and W3 -2 signs as shown in the Fabrication Manual, may be direct applied. The fabricator shall take due care to ensure that all sign backgrounds remain clean prior to application of inks and films, solvent wiping the sheeting in accordance with the manufacturer recommendations if necessary. Materials for fabricating signs shall be stored an d conditioned in accordance with the sheeting manufacturer recommendations prior to application. Environmental conditions under which the signs are fabricated shall be in accordance with the sheeting manufacturer recommendations.
651 661.3.4.1.1 -Flat Sheet Fabrication General Requirements: Flat sheet signs, reflective sign support strips, and delineators shall be fabricated of a single piece of sheet material without joints. The height and width of the blank shall be within plus or minus ⅛-inch tolerance of the approved shop drawing dimensions. Corner radii shall be within plus or minus 1/16 -inch tolerance of the dimensions shown on the approved shop drawings. Thickness of flat sheet material shall be in accordance with the requirements stated herein. Blanks shall have dimensions, corner radii, and hole punching in accordance with Standard Detail sheets TP1 -1A through TP1 -2B, or as otherwise shown in the Plans. All flat sheet signs shall be punched for reinforcing ribbing attachment, with the exceptio n of signs to be attached to a single u -channel or square tube support and Type 1 pole mounts as shown on Standard Detail TE9 -1, unless the Standard Details or Plans specify otherwise for a specific assembly or specific assembly type such as the single sup port GS -1C route marker arrangement shown on Standard Detail TP4 -1B.
661.3.4.1.2 -Extruded Panel Fabrication General Requirements: Extruded panel signs shall be fabricated of extruded aluminum channel sections, bolted together at the flanges, to form a s urface of the length, width, and depth required, to which the legend, border, and background have been applied. The width of the sign shall be within plus or minus ¼ -inch tolerance of the approved shop drawing dimensions. No splicing of sections will be permitted. Unless the required height of the sign is a specified number of feet plus an additional six (6) inches, all panels shall be twelve ( 12) inches in height. Only the minimum number of required six (6) inch height panels shall be used. If a six (6) inch panel is required, it shall be placed at the top of the sign. The panels shall be assembled in the shop and firmly bolted to form a sign of the length and width required. Additional stitch bolt holes shall be punched or drilled in the shop when required per Standard Detail TE8 -1. Before bolting, the webs of the panels shall be in the same plane to form a smooth and uniform surface and the ends shall be free from projections. Adjacent panels shall be color matched both day and night. It is inte nded that the signs shall be fabricated as single units. If the largest signs cannot be shipped as a single unit, they may be sectionalized after being fully assembled in the shop. Legend, shields, and borders which overlap the joints where the signs are sectionalized shall be removed and reinstalled in the field.
661.3.4.2 -Application of Retroreflective Sheeting: The application of retroreflective sheeting to the aluminum shall be done mechanically and in full accordance with the instructions of the m anufacturer of the sheeting. When manufacturing components such as demountable copy, demountable border, and reflective sign support strips, the fabricator may apply reflective sheeting to a large blank and then cut such components from the sheeting covered blank as permitted by and in accordance with the recommendations of the sheeting manufacturer. Sheeting shall cover one entire side of each flat sheet blank, which side shall be the sign face. When applied to extruded sign panels, reflective sheeting shall be rolled over each edge of the extrusion ⅜ -inch to prevent an opened surface on the sign face. The fabricator shall take due care and follow all manufacturer recommendations in order to ensure that the portion of sheeting rolled over the edges of e xtruded panels does not fracture at the edge of the panel face and will remain permanently adhered. Manufacturer recommendations typically require the use of heat in addition to edge rollers to provide
652 pressure. On six ( 6) inch wide extruded panels, the fabricator may roll the reflective sheeting over one edge only, provided the trimmed edge is completely adhered and sealed. In addition, the untrimmed edges of six (6) inch panels shall face downward upon final fabrication of the sign. Signs 48 -inches a nd less on the shorter side shall be covered by a single piece of reflective sheeting. On signs larger than forty -eight ( 48) inches on the shorter side, horizontal splicing shall be allowed. In this case, the section of sheeting on top shall overlap the b ottom section. Adjacent pieces shall be carefully matched for color to provide uniform reflective quality. All seams shall be straight, and the edges of adjustment pieces shall be overlapped a minimum of 3/16 -inch the length of the seam. When manufacturing signs, demountable components, and other products described herein using sheeting material that is “rotationally sensitive”, as defined in subsection 715.9.2, the manufacturing process shall result in the sheeting being oriented optimall y, as specified by the sheeting manufacturer, to retroreflect the light from vehicle headlights upon final field installation.
661.3.4.3 -Application of Demountable Copy: Each letter, symbol and border shall be secured to the sign surface with rivets meeting the requirements of subsection 661.2.10. The use of tape, glue or other substance to secure the copy to the sign face during fabrication or in its final form shall no t be allowed. Demountable copy, border, and shields shall be attached flush against sign faces after background material has been applied. Spacing and placement of all demountable components shall be as specified on the approved shop drawings. A suffici ent number of rivets shall be used to securely fasten demountable components to sign panels.
661.3.4.4 -Application of Overlay Films: Signs manufactured using opaque or transparent overlay films shall be manufactured by applying the films in accordance w ith all sheeting manufacturer recommendations. All films shall be cut on computer sign cutting equipment incorporating a knife cutting (blade) system. For signs utilizing transparent overlay film for the background and being greater than 48- inches on t he shorter side, splicing of sections of film shall be allowed if required. Each of the sections of film shall be carefully matched for color to provide uniform reflective quality. The method of splicing shall be a butt splice and no overlap shall be all owed for transparent films.
661.3.4.5 -Screen Processing: All screening shall be done in a workmanlike manner and as recommended by the manufacturer of the reflective sheeting. All legends, symbols, shields, and borders shall be of the color specified and screened on the sign as shown on the Plans. Finished colors after screening shall be in accordance with the color requirements specified in the MUTCD. The fabricator shall adhere to all sheeting manufacture screening recommendations pertaining to, but not limited to, ink thinning; printing equipment including fabric, stencil, and squeegee; and screening method. Finished signs shall have a uniform color and tone, with sharply defined edges of legend and border and without blemishes on the sign backg round. Free hand painting will not be permitted.
653 661.3.4.6 -Packaging: All signs shall be protected by packaging during shipment and storage. The packing shall be adequate to prevent moisture, abrasive, or excessive pressure damage to any part of the sign, including any demountable legends or borders. Before packaging, all signs shall be free of moisture and all inks shall be thoroughly dry. All screen -printed signs shall be allowed to dry for a minimum of 24 -hours inside of the fabrication facility before packaging. Plastic wrapping which may trap moisture shall not be used. Signs shall be packaged face -to-face and back -to-back placing slip sheeting (silicone side of liner) against each sign face and a non -permeable separator (such as a piece of p lastic) shall be placed between signs. Finished signs shall be shipped on edge and shall not be stacked. Packaging methods which will result in heavy pressure on the face of the signs shall not be used. All packaged signs shall be kept entirely dry unti l installation. If the sign packaging becomes wet at any time prior to installation, remove the signs, thoroughly dry off and repackage with dry materials. Adhesive tapes shall not be applied to any sign surfaces. Signs shall be adequately protected and supported to avoid scuffing. Signs delivered for use on the Project shall be stored off the ground. The signs shall be stored in a manner meeting the recommendations of the fabricator and the approval of the Engineer which will prevent moisture on the sign faces and excessive ambient temperatures.
