1 540 - HIGHWAY FENCE - OPSS GENERAL This section covers the requirement for the items related to the erection of fencing on or along the highway right-of-way limits, including connections to cross fences, in the case of Class III, Class IV and Class V highways (Special Controlled Access Highways, Major and Minor Highways not designated as fully or modified controlled access) and at 0.3 m inside right-of-way limits for Class I and Class II highways (Freeways and Expressways and Staged Freeways and Expressways); (except that for Class II highways the fence may be erected anywhere inside the right-of-way limits to serve the current stage of construction only). For full details of fencing Rights-of-Way, the designer is referred to Admin-Property Directive B Highway Fence Tender Items Highway fence provides for the erection of farm fence along highway right-of-way limits. Gates and brace panels are provided where required, as separate tender items. Highway fence is erected with the fence fabric fastened to the front face of the posts, as viewed from the highway; except on outside curves of 1750 m or smaller radius, when it must be fastened to the back of the posts so as to maintain proper tension. In wooded areas not designated for clearing, the close cut clearing necessary to allow the erection of the fence is included in the tender item for the fence. Highway Fence Brace Panels Gates Specifications The requirements for the erection of highway fence is contained in OPSS Special Provisions The designer should investigate to determine whether any of the Special Provisions listed in Chapter "E" require inclusion in the contract documents Standard Drawings The designer must be familiar with the Ontario Provincial, Standard Drawings; (see OPSD 900 Series for Highway Fence) B540-1

2 540.2 COMPUTATION The items for Highway Fence are Plan Quantity Payment items Source of Information Generally, new highway fencing is erected on the right-of-way limits as a replacement for existing fencing removed under the same contract; refer to Property Agreements and P-Plans for details of existing fences and gates Methods of Calculation A. Highway Fence The unit of measurement for highway fence is the metre. Lengths of Highway fencing are scaled from plans, and measured horizontally, with no deductions made for brace panels or gates. Openings in the right-of-way fence where no gate is provided are not measured, but are treated as two fence terminals. Normally, no fencing is computed for cross fences, unless there is an agreement with the property owner stating otherwise; following the installation of the cross fence brace panel, the existing fence fabric is unrolled back into place to meet the new right-of-way fence. B. Brace Panels The unit of measurement for brace panels is "each". A brace panel consists of a wooden end, anchor, corner or gate post, together with a wooden brace post, diagonal wooden brace and counter-diagonal brace wire. In solid rock, where steel posts only are chosen, brace panels are constructed using angle-iron posts and braces. Brace panels are computed in accordance with the following requirements (see illustrations): a) At cross fences (separating property owners) - 3 panels require: one forming part of the cross fence, and two erected as part of the highway fence b) At cross fences (Not separating property owners) - 1 brace panel is required installed on the cross fence at the straining post. c) At all horizontal angles exceeding 22-2 panels d) On all curves of radius 900 m or less - 2 panels at each end of curve, plus 2 panels at midpoint e) Gate locations and openings - 2 panels at each site in fence f) At all vertical angles exceeding 22-2 panels g) At crossings of watercourses(maximum span - 6 m) - 2 panels h) Terminals - 1 panel per terminal B540-2

3 1) Existing fence (adjacent to a removed section). 2) New fence i) On clear fence runs with none of the - 2 panels per location(distance foregoing situations between double panels at approx. 200 m intervals, max. 230 m. C. Gates The unit of measurement for gates is "each," with double gates counted as one gate DOCUMENTATION A. Contract Drawings Except for special fencing requirements such as easements, stage construction and irregularshaped areas (e.g. interchange ramps), fences and gates are not required to be shown on the drawings. Where fences are shown, the following details must be given on the drawings: 1) Fence and gate symbols 2) Standard Drawing No. (e.g. OPSD ) B. Contract Documents Documentation Accuracy Fencing quantities, scaled from plans or taken from Property Agreements, may be entered directly onto the "Quantities - Miscellaneous 2" sheet, showing stations and location, with offsets if required. Each cross fence must be shown by chainage for the purpose of listing brace panels. Brace panel quantities are shown in the brace panel column opposite the main run, cross fence or gate entry, as appropriate. Gate chainages for the centre of each gate are shown following the respective fence entry, with an offset distance where the gate is set back from the fence line. The gate opening width is shown in the gate column, (e.g. "1.2", and, for double gates, "7.0"). Show "single gate" or "double gate", as appropriate, in the "Location and Position" column, against each gate entry. Stations and quantity entries are recorded to the nearest whole metre. Offsets are recorded in 0.1 of a metre. Spot checking required B540-3
