This work consists of furnishing materials, making and preparing signs and delineators, erection and installation of signs and delineators, and performing incidental work.
632.2MATERIALS
Materials will conform to the following sections: A.Highway Signs and Delineators: Section 982. B.Reinforcing Steel: Section 1010 . C.Concrete: Section 462. D.Bolts: High-strength bolts will conform to Section 972. Bolts for mounting sign panels to posts and backing hardware will conform to Section 982.
632.3CONSTRUCTION REQUIREMENTS
Highway signs, delineators, and object markers will comply with the current edition of the MUTCD and Standard Highway Signs, issued by the U.S. Department of Transportation, FHWA. A.Signs: 1.Location and Position: The location of each sign will be established by a stake bearing the sign number as determined from the plans. Posts will be in a plumb position and the flanges of structural shape posts or other supports will lie in the same plane. The post will not extend above the top of the sign. Extruded panels will be flat and straight and will be erected on the posts in a leveled position with the face of each extrusion flush with adjoining extrusions. Bolted connections between adjoining panels will be straight. Offsets or gaps exceeding 1/16 inch will not be permitted. 2.Post Size: Post size will be as specified in the contract for each sign. Sign post lengths shown in the contract are estimates for bidding purposes only. The Contractor will field verify the post length prior to ordering. 3.Date Decal: The Contractor will affix a date decal to each new sign installed. The date decal is a 2 inch by 2 inch self-adhesive sticker with removable paper backing. The date decal displays the last two digits of the year the sign was installed and will consist of two contrasting colors. The date decal will be placed in the lower left corner on the back of flat aluminum signs. The date decal will be placed in the lower left corner on the front of extruded aluminum signs. The date decal on extruded aluminum signs will be of the same color as the background of the sign and will be retroreflective. Sign supports and other 632 Page 428obstructions will not block the view of the date decal upon completion of the sign installation. B.Object Markers: Object markers of the type specified will be erected at the locations shown in the plans or as directed by the Engineer. C.Delineators: Delineators will be mounted as shown in the plans. D.Perforated Tube Posts: Perforated tube posts will be installed in accordance with the contract or as directed by the Engineer. E.Steel Posts: Steel posts longer than the required length will be cut off or spliced in a satisfactory manner. Areas where the galvanizing has been damaged will be coated with an approved zinc rich paint. Structural properties of steel posts to be reused will not be modified without the approval of the Engineer. F.Wood Posts: Wood posts will be embedded a minimum of 4 feet. Wood posts longer than the required length will be cut off or set deeper. Holes for setting wood posts will be a minimum diameter of 6 inches larger than the greatest side dimension of the post. The posts will be set, backfilled, and compacted with material placed in layers not to exceed 6 inches. G.Sign Bridges and Overhead Cantilever Sign Supports: Sign bridges and overhead cantilever sign supports will be constructed in accordance with the details in the plans and at the locations shown. Anchor bolts/rods will be tightened in accordance with Section 635.3 E. H.Bridge Mounted Sign Support Assemblies: Bridge mounted sign support assemblies will be constructed in accordance with the details and at the location shown in the plans. I.Fixed Base Assemblies: Fixed base assemblies will be assembled in accordance with details in the plans. High strength bolted connections will be tightened as specified using load indicator washers. J.Slip Base Assemblies: Slip base assemblies will be assembled in accordance with the details in the plans. The top of the concrete footing/grout pad will be placed flush with the finished grade. The mounding of soil around the footing will not be permitted. K.Reflective Sheeting: Reflective sheeting will be of the type specified. L.Concrete Footings: 1.Construction: Concrete footings will be constructed as shown in the plans. When the signpost footings extend into rock, the portions of the plan specified depths in solid rock should be reduced by one half. Reduction from the plans shown quantities of concrete for footings will be made for any changes in footings depths. Posts will be anchored to footings as shown on the plans. Dirt excavated for the footings will be disposed of as directed by the Engineer. 632 Page 4292.Protection and Cure: Concrete footings will be protected and cured in accordance with Section 460, except the minimum curing time will be 72 hours. The finished surface of the concrete footings will be flush with the existing ground and will present a neat and smooth appearance. M.Remove, Salvage, Relocate, and Reset Sign: The Contractor will remove signs, post, and bases for reset as shown in the plans. The Contractor will reuse existing extruded aluminum panels, posts, footings, and hardware where specified. All existing posts, bases, and signs listed in the plans that are scheduled for removal will be dismantled. All bolts, nuts, and washers will be placed in containers to keep the hardware separated. Backing materials will be separated from the signs and may be reused at the Contractor’s discretion. Non-threaded connections (rivets) will be cut when necessary to reduce sign sections to a 4 foot x 6 foot maximum size. Wooden posts will be carefully removed to avoid damage and cleaned of excess dirt and neatly stockpiled separate from the steel posts. The resultant holes in the ground from removal of wooded posts will be backfilled to the satisfaction of the Engineer.
