Article 1 — Description
Furnish and install treated timber poles.
Article 2 — Materials
Use new treated southern pine timber poles in accordance with ANSI O 5.1 and this Item. Use ANSI Class 5 treated timber poles for electrical services and ANSI Class 2 for all other applications, unless otherwise shown on the plans. Ensure poles are free of pith holes at the tops and butts. Do not use poles that have a trimmed scar with a depth greater than 2 in. if the diameter is 10 in. or less, or 1/5 the pole diameter at the scar location if the diameter is more than 10 in. Provide poles that do not deviate from straightness by more than 1 in. for each 10 ft. of length. A pole may have sweep in one plane and one direction (single sweep), provided a straight line joining the midpoint of the pole at the butt and the midpoint of the pole at the top does not at any intermediate point pass through the external surface of the pole. Timber poles with more than one complete twist of spiral grain are not acceptable. Furnish treated poles in accordance with AWPA to the minimum net retention and penetration of preservative treatment in accordance with Table 1. Table 1 AWPA Commodity Specification and Use Category for Poles Product AWPA Commodity Specification1 AWPA Use Category2 Poles ( southern pine) D UC4C 1. For minimum preservative retention requirements, refer to AWPA Use Category System Standard U1, Commodity Specification D , for the preservative provided for the s outhern p ine poles. For preservative penetration and assay zone requirements, refer to AWPA Use Category System Standard T1, Commodity Specification D. 2. Refer to this designated U se Category when locating the minimum required retention for the provided preservative in AWPA Use Category System Standard U1 , Commodity Specification D. Mark all poles by branding in accordance with Table 2. Table 2 Timber Pole Markings Marking Description of Marking PTC Supplier’s code or trademark (e.g., Pole Treating Company) F-20 Plant location and year of treatment (e.g., Forestville, 2020) SPC Species and preservative code (e.g., southern pine, creosote) 5-35 Class length (e.g., Class 5, 35 -ft. pole) Place the bottom of the brand squarely on the face of the pole 10 ft. (±2 in.) from the butt. Furnish a treatment certification with every shipment of treated timber poles that includes: name of treating company, location of treating plant, applicable product standard (AWPA U1), charge number, 877 date of treatment, contents of charge (poles), preservative treatment, and actual preservative retention values.
Article 3 — Construction
Perform work as shown on the plans and in accordance with this Item. Use established industry and utility safety practices while installing poles located near overhead or underground utilities. Consult with the appropriate utility company before beginning work. Set the pole a minimum depth in accordance with Table 3, unless otherwise shown on the plans . Table 3 Pole Setting Depth Pole Length (ft.) Min Setting Depth (ft.) 25 or less 4.5 26–30 5.0 31–35 5.5 36–40 6.0 41–45 6.5 46–50 7.0 Locate timber poles as shown on the plans or as directed. Drill holes for setting poles a minimum of 1.5 diameters of the pole butt. Set the poles plumb, unless otherwise shown on the plans. Backfill the holes thoroughly by tamping in 6- in. lifts. After tamping to grade, place additional backfill material in a 6- in. high cone around the pole to allow for settling. Use material equal in composition and density to the surrounding area. Repair surface where existing surfacing material is removed, such as asphalt pavement or concrete riprap, with like material to equivalent condition.
Article 4 — Measurement
This Item will be measured by each timber pole installed.
Article 5 — Payment
The work performed and materials furnished in accordance with this Item and measured as provided under “Measurement” will be paid for at the unit price bid for “Treated Timber Pole” of the various lengths and classes specified. This price is full compensation for furnishing and installing timber poles; all hardware; and materials, equipment, labor, tools, and incidentals. This payment clause excludes payment for t reated t imber p oles when subsidiary to another Item.
