607.01 607-1 SECTION 607 FENCES DESCRIPTION
607.01 This work consists of the construction of fence and gates, and removal of temporary
plastic fence per these specifications and in conformity with the lines and grades shown on the plans or established. MATERIALS
607.02 Materials shall meet the requirements specified in the following subsections:
Woven Wire 710.02 Barbed Wire 710.01 Chain Link Fabric 710.03 Fence Posts 710.07 Snow Fence 710.04 Timber for Wood Noise Barrier 710.06 Reinforcing steel shall conform to Section 602. Concrete shall conform to Section 601. Foundation concrete for fence posts, braces, anchors , and gates shall be Class B. Concrete with lightweight aggregates conforming to ASTM C330 will be permitted. Field mixed concrete consisting of a minimum of one part cement to six parts of aggregate by volume may be used in lieu of Class B if approved. Pr e-packaged concrete may be used if approved. Fence (Plastic) shall be orange -colored material, at least 4 feet in height. CONSTRUCTION REQUIREMENTS
607.03 The Contractor shall perform such clearing and grubbing as may be necessary to
construct the fence to the required grade and alignment. The r ight-of-way fence shall be constructed approximately 6 inches inside the boundary of the highway right of way shown on the plans or as staked. Anchorages, footings or fence appurtenances shall not extend beyond the limits of the highway right of way without the written consent of the abutting property owner. At locations where breaks in a run of fencing are required, at intersections with existing fences, or at ditch, canal, or channel crossings, appropriate adjustments in fence alignment and post spacing shall be made to satisfy the requirements for the type of closure indicated or the conditions encountered. When the plans require that posts, braces , or anchors be embedded in concrete, they shall be securely braced to hold the posts in proper position until the concrete has set sufficiently to hold the posts. Unless otherwise permitted, materials shall not be installed on posts, or stress placed on gu ys and bracing set in concrete until the concrete has set sufficiently to withstand the stress. 607.04 607-2 The tops of all posts shall be set to the required grade and alignment. Cutting of the tops or bottoms of treated timber posts will be allowed only with the approval of the Engineer. Posts cut in the field shall have the cut surfaces protected with two coa ts of an approved wood preservative. Wire or fencing of the size and type required shall be firmly attached to the posts and braces in the manner indicated. All wire shall be stretched taut and be installed to the required spacing. Wood noise barrier fence shall be constructed according to the details shown on the plans. All fence boards shall be tightly butted to minimize cracks. Fence (Plastic) shall be placed as shown on the plans or as directed to define the limits of the work area beyond which no access is allowed to the surrounding wetlands or vegetation to be protected. METHOD OF MEASUREMENT
607.04 Fence will be measured by the linear foot. Measurement will be along the base of
the fence from outside to outside of end posts for each continuous run of fence , including length of barbed wire gates, but excluding the length of driveway gates and walk gates. Driveway gates and walk gates will be measured as complete units of the size and type specified. Gates shall be the same type and height as the adjacent fence unless otherwise designated. End posts, corner posts , and line brace posts required for chain link fence, barbed wire , and combination wire fence will be measured by the actual number used. End posts, corner posts , and line brace posts for snow fence or barrier fence will not be measured and paid for separately but shall be included in the work. Line posts required for reset fence will be measured by the actual number used. Line posts required for new fence will not be measured separately but shall be included in the contract unit price for new fence. End Posts Special, Corner Posts Special, and Line Brace Posts Special required for Fence (Deer) will be measured by the actual number used. Fence Wood (Noise Barrier) will be measured by the linear foot. Fence (Plastic) will be measured by the linear foot. Posts will not be measured and paid for separately but shall be included in the work. Measurement will be along the base of the fence from outside to outside of end posts for each continuous run of fence, and shall include all wood, hardware, concrete, reinforcing steel, excavation and backfill, and all other incidentals to the erection of the fence. 607.05 607-3 BASIS OF PAYMENT
607.05 The accepted quantities of fence will be paid for at the contract unit price for each of
the pay items listed below that appear in the bid schedule. Payment will be made under: Pay Item Pay Unit Fence (____) (_____Inch) Linear Foot (____Foot) Gate (____) Each Line Post Each End Post Each Corner and Line Brace Post Each End Post (Chain Link) Each Corner and Line Brace Post (Chain Link) Each End Post Special Each Corner and Line Brace Post Special Each Deer Gate Each Fence Wood ( Noise Barrier) (_____Inch) Linear Foot Fence (Plastic) Linear Foot Payment for Fence (Plastic) shall be full compensation for furnishing, erecting, maintaining, removing, and disposing of all materials required. Fence (Plastic) shall remain the property of the Contractor. 607.05 607-4 THIS PAGE INTENTIONALLY LEFT BLANK 608.01 608-1 SECTION 608 SIDEWALKS AND BIKEWAYS DESCRIPTION
608.01 This work consists of the construction of bituminous or concrete sidewalks, bikeways ,
and curb ramps per these specifications and in conformity with the lines and grades shown on the plans or established. MATERIALS
608.02 Materials shall meet the requirements specified in the following subsections:
Joint Fillers 705.01 Bed Course Material 703.07 Concrete for sidewalks, bikeways, and curb ramps shall be Class B and meet the requirements of Section 601. Bituminous material for sidewalks, bikeways, and curb ramps shall meet the requirements of Section 403. Concrete and bituminous mixes will be subject to inspection and tests as required to ensure compliance with quality requirements. CONSTRUCTION REQUIREMENTS
608.03 Concrete Sidewalks and Bikeways .
a.Excavation. Excavation shall be made to the required depth and to a width that will permit the installation and bracing of the forms. The foundation shall be shaped and compacted to a firm even surface conforming to the section shown on the plans or as staked. When the Engineer determines that material is uncompactable, the material shall be removed and replaced per subsection 206.03.
b.Forms. Forms shall be of wood, metal, or other suitable material, and shall extend for the full depth of the concrete. All forms shall be straight, free from warp , and of sufficient strength to resist the pressure of the concrete without springing. Bracing and staking of forms shall be such that the forms remain in both horizontal and vertical alignment until their removal. A satisfactory slip -form method may be use d.
c.Placing Concrete. The foundation shall be thoroughly moistened immediately before the placing of the concrete. The proportioning, mixing , and placing of the concrete shall be per the requirements for the class of concrete specified.
d.Finishing. The surface shall be floated with a wooden or magnesium float and given a transverse broom finish. Plastering of the surface will not be permitted. All required hand finishing shall be performed in conformance with subsection 601.12(a). All outside edges of the slab and all joints shall be edged with a 1/4- inch radius -edging tool.
e.Joints. Expansion joints, at intervals of not more than 500 feet, shall be filled with 1/2-inch-thick full depth, preformed expansion joint filler. The sidewalk or bikeway shall be divided into sections by dummy joints formed by a jointing tool or other acceptable means as directed. These dummy joints shall extend into the concrete for at least a quarter of the depth and shall be approximately 1/8 inch wide. Dummy joints shall be spaced at intervals approximately equal to the width of the sidewalk or bikew ay.
