dimensions of 1.75" square and a minimum thickness of 14ga. Picket holes in the ForeRunnerlm <br />rail shall be spaced 4.98" o.c. Picket retaining rods shall be 0.125" diameter galvanized steel. <br />Posts shall be a minimum of 2 -1/2" square x 12ga. High quality PVC grommets shall be <br />supplied to seal all picket -to -rail intersections. <br />Fabrication <br />A. Pickets, rails, and posts shall be precut to specified lengths. ForeRunnerim rails shall be pre - <br />punched to accept pickets. <br />B. Grommets shall be inserted into the pre - punched holes in the rails and pickets shall be inserted <br />through the grommets so that pre - drilled picket holes align with the internal upper raceway of <br />the ForeRunnerTm rails. (Note: This can best be accomplished by using an alignment template.) <br />Retaining rods shall be inserted into each ForeRunnerT"' rail so that they pass through the <br />predrilled holes in each picket, thus completing the panel assembly. <br />C. Completed panels shall be capable of supporting a 600 Ib. load (applied at midspan) without <br />permanent deformation. Panels without rings shall be biasable to a 25% change in grade; <br />panels with rings shall be biasable to a 115% change in grade. <br />D. Gates shall be fabricated using Aegis IITm panel material and gate ends having the same <br />outside cross - section dimensions as the ForeRunnerTM rail. All rail and upright intersections <br />shall be joined by welding. All picket and rail intersections shall also be joined either by welding <br />or by the same retaining rod process used for panel assembly. <br />Part 3 - Execution <br />Preparation: All new installation shall be laid out by the contractor in accordance with the construction <br />plans. <br />Installation: Fence posts shall be set in accordance with the spacing shown in Table 2, plus or minus <br />1/2 ", depending on the nominal span specified. <br />Table 2 — Post Spacing Requirements <br />Span 1 6 Nominal (71-3/8" Rail) I 8 P <br />Post Size 2-1/2" _ 3 2 -1/2' 3" T2 -112 <br />Bracket Type Standard (BB301) i Angle (BB304) I Standard <br />Post Settings t Y2 O.C. 75" 7 5-1/276 -1 77" 94 -1/2" <br />al (91 -1/4" Rail) <br />3.1 2-1/2„ 3 3" <br />01) j Angle (BB304) <br />95" ! 96" i 96 -1/2" <br />Gate posts shall be spaced according to the gate openings specified in the construction plans. <br />Concrete Footings for steel posts shall be per manufacturer's recommendations and details as shown. <br />Cleaning: The contractor shall clean the jobsite of excess materials.. <br />Payment for Ornamental Steel Fencing shall be paid at the contract unit prices listed in the Bid Proposal <br />for Ornamental Steel Fencing and shall include all equipment, post hole excavations, concrete footings <br />and other incidentals as necessary to install complete and in place for the project as shown on the <br />drawings and specified herein <br />City of Santa Ana RFP 13 -064 <br />Page 21 <br />2511 -26 <br />
