SECTION 831 — PEDESTRIAN CHAIN LINK FENCE – ALUMINUM — PEDESTRIAN CHAIN LINK FENCE – ALUMINUM
831.01 Description.
This work includes providing aluminum chain link fence, of various colors and configurations, at the required locations.
831.02 Materials.
Use materials for pedestrian chain link fence that conform to SECTION M08 and the following additional requirements. Wire Fabric. Use aluminum chain link fence wire fabric that is No. 9 gauge (0.148-in. diameter) wire fabric and that has a uniform diamond mesh measuring approximately 2 in. between parallel sides. Use wire fabric that is woven from aluminum alloy 6061 T89-94 (ASTM B211) wire having a minimum tensile strength of 50,000 psi. After the fabric has been woven, clean to remove all weaving compounds and foreign matter. Posts. Use aluminum posts that are 2½ -in. Schedule 40 (2.875-in. OD) pipe weighing 2.004 lb/ft. Use posts that are aluminum alloy 6061-T6 (ASTM B221). Rails. Use aluminum rails that are 1¼ -in. Schedule 40 (1.660 -in. OD) pipe weighing 0.786 lb/ft. Use posts that are aluminum alloy 6061-T6 (ASTM B221). Fittings and Appurtenances. Use fittings (tension bars, rail splices, washers and post connection clamps) that are aluminum alloy 6061-T6 (ASTM B221). Use nuts that are aluminum alloy 6061-T6 (ASTM B316). Use bolts that are aluminum alloy 2024-T4 (ASTM B316).
a.Wire Fabric Connections. Securely fasten the aluminum fabric to all terminal posts by 1 in. × ¼-in. tension bars with ⅞-in. × ⅛-in. tension bands (aluminum alloy 6063-T5, ASTM B221) spaced approximately 6 in. apart and to all line posts and rails with No. 6 gauge (0.194-in. diameter) wire ties (aluminum alloy 1100-H18) approximately 6 in. on center.
b.Tens ion Wires . Use tension wires that are 7-gauge (minimum) galvanized coil spring steel wire.
c.A nchorage Fittings . Use aluminum base plates that are aluminum alloy 6061- T6 (ASTM B221). Use anchor bolts that are ¾-in. diameter galvanized bolts 10 in. long (ASTM A193, AISI Type 304). Coat the portions of the aluminum base plate that will be in contact with
Part 800 — Bridge Structures August 2025
SECTION 831 — PEDESTRIAN CHAIN LINK FENCE – ALUMINUM 800-179 the concrete parapet and the steel anchor bolts with an approved aluminum impregnated caulking compound.
831.03 Construction Methods.
Set the fence posts vertical with a maximum post spacing 8 ft – 0 in. Secure the fabric with ties, stretchers, and tensioning devices sufficiently to resist wind and weather loadings without noticeable sagging, billowing, or skewing of the square patterns. Tolerance. Standard plus or minus mill tolerances on all framework members and chain link fabric will apply.
831.04 Method of Measurement.
Pedestrian Chain Link Fence - Aluminum will be measured by the number of linear feet installed. Measurement will be along the top of the fence from centerline to centerline of end posts for each continuous run of fence.
831.05 Basis of Payment.
The Department will pay for the completed and accepted quantities as follows. Pay Item Pay Unit Pedestrian Chain Link Fence – Aluminum LF The price constitutes full compensation for all labor, materials, tools and equipment, and all incidentals required to finish the work, complete and accepted.
