419 tie wires or clips. A sufficient qu antity of individual fabric ties or clips shall be furnished to provide for attaching the fabric to line posts at twelve ( 12) inch vertical spaces. 608.8 -PAINTS AND PAINTING : Zinc-coated, triple -coated and aluminum -coated metal parts in the fence structure shall not be painted. After erection is completed, all fence construction will be inspected by the Engineer. All parts of the fence and gates (including bolts and nuts) from which the coating has been abraded so that the base metal is exposed shall be spot -painted with a zinc rich primer in the case of zinc - coated and triple -coated steel and with aluminum paint in the case o f aluminum -coated steel. Wood posts and braces shall be painted when called for on the Plans. 608.9 -ELECTRICAL GROUNDS : All types of fences shall be grounded where a power line passes over the fence. The ground shall be installed immediately below the point of crossing. The ground shall be accomplished with a copper clad rod, eight ( 8) feet long and 5/8 inch (nominal) in diameter, driven vertically until the top is approximately six (6) inches below the ground. A # 6 solid copper conductor shall be clamped to the rod and to the fence in such a manner that each element of the fence is grounded. Similar grounds shall be installed at a maximum of every 2,000 feet length of fence, whether or not there a re power line crossings. For sections of fence less than 2,000 feet one ground shall be provided midway between the end posts.
608.10 Junctions With Existing Fences :
Where the right -of-way fence intersects or joins existing fence, the Contractor shall make the junction between the fences in the manner specified. An end post corresponding in strength to the type used in the right -of-way fence shall be set on the line of the existing fence and approximately four ( 4) inches outside the centerline of the highway right -of-way fence. Existing fencing fabric, or similar, shall be stretched and tied to this end po st in conformance with the construction requirements for the right -of-way fence. No direct connection shall be made between the existing fence and the highway right -of-way fence. All junctions shall be made in a workmanlike manner and will be subject to the approval of the Engineer.
608.11 Temporary Fence :
Temporary fence, when called for as a separate bid item, shall be erected at locations as shown on the Plans or as directed by the Engineer. The Contractor shall set back and re -erect existing fences, erect temporary fences from salvaged fence material, or erect Electric fences at the direction of the Engineer.
608.12 Method of Measurement :
Fence will be measured by the linear foot. Measurement will be along the bottom wire of the fence from outside to outside of end posts for each continuous run of fence. The lengths occupied by gates will not be included in this measurement. For farm -field fence with wood posts, the distance between posts for each intermediate assembly will be measured only once; the lap in the fencing fabric at intermediate assemblies will be included in the cost of the fence. Temporary fence and gates, subject to the p rovisions specified, will be measured along the bottom of the fence from outside to outside of end posts for each continuous run of fence. Gates, except when used when temporary fence, will be measured as complete units of the size and type specified.
