The types of signs covered by this specification are:
1. Type A signs
2. Type B signs
3. Type D signs
4. Type E signs
5. Type F signs
6. Milemarkers
All materials shall meet the requirements of Division 10 shown below:
High strength bolts, nuts, and washers Subarticle 1094-1(A)
Zinc-rich paint Article 1080-9
(A) General:
The Contractor shall provide new mounting bolts, washers, hex nuts, backing plates, and all hardware for all signs, existing and proposed, to be mounted on existing or proposed supports.
No welding, cutting, or fabrication in any manner will be permitted in the field, except for the cutting of U-channel post material for the supports and the framing and cross-bracing for Types D, E, and F signs, and for the drilling of holes for attaching demountable legends and borders which cannot be attached in the shop. Necessary field drilling of Zbars for attaching new signs to existing supports will be permitted.
Two coats of a zinc-rich paint shall be used in touching up the tops of U-channel posts damaged in driving; cut ends of U-channel posts, frames, and cross-bracing; field-drilled holes; and damaged areas on all galvanized materials.
(B) Location:
The Engineer will establish the location of each sign longitudinally. The Contractor shall be responsible for the proper elevation, offset, level, and orientation of all signs.
(C) Orientation of Signs:
Signs shall be oriented and adjusted where necessary to minimize specular reflection. Horizontal edges of signs shall be level, and faces of signs shall be vertical.
(D) Clearing for Sign Sight Distance:
The clearing of vegetation in front of signs erected by the Contractor will be required where necessary to achieve proper sight distance to the sign. The Engineer will determine where clearing is required, and the amount of clearing at the sign locations. The clearing shall be done in accordance with Section 200.
(E) Type A and B Signs, Erection:
The signs shall be attached to supports as shown in the plans or in the approved shop drawings. The face of the sign shall be flat. Any appreciable buckling or warping of the sign face will be cause for rejection of the entire sign.
Type A & B secondary signs shall be erected as shown in the plans. They shall be affixed by bolting the stringers directly to the supports, or by bolting vertical "Z" bars to the stringers of the secondary sign and the primary sign. The required method of attachment will be shown in the plans. When the Contractor is required by the plans to furnish the signs, he shall also furnish the vertical "Z" bars.
(F) Type D, E, and F Signs, Erection:
The signs shall be attached to U-channel posts as shown in the plans. All mounting hardware shall be as shown in the plans.
(G) Milemarkers, Erection:
The Engineer will establish the location of each milemarker longitudinally. The Contractor shall be responsible for the proper elevation, offset, level, and orientation of the milemarkers.
(H) Care and Handling of Signs:
The Contractor shall be responsible for the signs until they are accepted by the Engineer for maintenance. Any damaged sign will not be accepted. Any damage to the signs before final acceptance of the project shall be repaired, or otherwise corrected, by methods approved by the Engineer.
No repair work shall be done until the Engineer gives written approval. The Contractor shall make repairs only under the supervision of the Engineer.
The handling, transportation, and storage of all types of traffic signs shall be in accordance with the sheeting manufacturer's recommendations. Failure to comply with the manufacturer's recommendations during the handling, transportation, and storage of the signs will be cause for rejection of the signs.
(I) Final Cleaning Up:
Before final inspection, the Contractor shall perform such cleaning of exposed sign and support surfaces, and repair of the site as may be deemed necessary by the Engineer, to insure the effectiveness and neat appearance of the work.
(J) Covering of Signs:
The Contractor shall cover signs which have been erected on roads open to traffic, but which are not yet applicable to traffic. The signs shall remain covered until the Engineer instructs the removal of the covering. The covering shall be layered burlap material which will prevent the messages from being read or seen during both day and night conditions.
The quantity of ground-mounted signs and milemarkers to be paid for will be the actual number of signs and milemarkers which have been erected and accepted. Type F sign assemblies will be measured as one sign.
The quantity of ground-mounted signs and milemarkers, measured as provided in Article 9044, will be paid for at the contract unit price each for "Type _____ Signs, Erection" and "Milemarkers, Erection".
Such prices and payments will be full compensation for all work covered by this section including but not limited to transporting the signs and milemarkers to the project, storing the signs and milemarkers as necessary, clearing vegetation, furnishing mounting hardware, erecting the signs and milemarkers, final cleaning up, and covering and uncovering signs.
Payment will be made under:
