11.Fabrication of Sign Posts. The total length of posts shown in the Contract Documents is estimated. The number, type and size of posts show n in the Contract Documents are determ ined from theoretical sections. Do not order sign posts until the Engineer provides the length of each post for th e sign or the sign assembly based on actual field measurements ( see subsection 812.3c. ). Wood posts, steel "U" posts and perforated square steel tube posts may be ordered in stock lengths and cut to the required length in the field. Do not torch-cut steel posts. Drill breakaway holes in the wood posts at the project site. Treat all field cuts and drilled holes in wood po sts with preservative material. Paint all cut ends of steel posts with zinc-rich paint. Fabricate steel beam posts, base plates and fuse plates to the specified dimensions. Drill the specified holes in the posts and plates. The preferred method of cutting pl ates is sawcuts; however, flame-cutting is permitted. Grind all edges smooth and remove all burrs projecting beyond the planes of the plate faces, cuts or drilled holes. After the base plates are galvanized, remove all runs or beads in the areas where washers are placed. 812.3 CONSTRUCTION REQUIREMENTS
a.General. Erect the permanent signing as necessary to expedite the completion of the project and the opening of the highway. The Engineer may require that the Contractor mobilize permanent signing operations whenever it is feasible to complete a portion of the project. The Contractor may have to mobilize and, upon completion of all currently feasible work, suspend the permanent signing operations more than once before the project is completed. It is the Contractor’s responsibl e to verify the utility locations. If a temporary sign interferes with the installation of a permanent sign, remove and reset the temporary sign to a location designated by the Engineer.
b.Sign Location and Orientation. Locate and stake each sign inst allation according to the Contract Documents. Orient the signs in relation to the highway alignment as shown in the Contract Documents. If the Contract does not include the item of Contractor Construction Staking, the Engineer will stake the location of each sign.
c.Sign Post Lengths. The Engineer will provide the Contractor with the length of each sign post. 812 - PERMANENT SIGNING
800-41 If the contract includes Contractor Construction Staking, provide the Engineer with the information
necessary to determine the length of each sign post. Provide the Engineer with the vertical and horizontal measurements from the top of the pavement edge to: the ground line (for posts with no footings) the top of the footing (for posts with footings) the top of the stub post base plate (for steel beam breakaway posts) If the Contract does not include the item of Contractor Construction Staking, the Engineer will obtain the measurements necessary to determine the length of each sign post.
d.Sign Post Installation.
1.Footings.
a.Post Holes for Wood Posts. Excavate the post holes to the shape and dimensions shown in the Contact Documents. Prevent water from entering the excavated holes.
b.Concrete Footings for Wood Posts and Steel Beam Stub Posts. Excavate the footings to the shape and dimensions shown in the Contract Documents. Remove all non-compacted material from the excavation.
