ST. BARBARA CATHOLIC SCHOOL TASK 2 75-24272-01 <br />DIOCESE OF ORANGE SEPTEMBER 12TH, 2024 <br />SANTA ANA, CA BID & PERMIT SET <br /> <br />DECORATIVE METAL FENCES AND GATES 323119 - 6 <br />3.3 DECORATIVE FENCE INSTALLATION <br />A. Install fences according to manufacturer's written instructions. <br />B. Fence post shall be spaced according to Table 3, plus or minus ½”. For installations that must <br />be raked to follow sloping grades, the post spacing dimension must be measured along the <br />grade. Fence panels shall be attached to posts with brackets supplied by the manufacturer. <br />Posts shall be set in concrete footers having a minimum depth of 36” (Note: In some cases, <br />local restrictions of freezing weather conditions may require a greater depth). The “Earthwork” <br />and “Concrete” sections of this specification shall govern material requirements for the concrete <br />footer. Posts setting by other methods such as plated posts or grouted core-drilled footers are <br />permissible only if shown by engineering analysis to be sufficient in strength for the intended <br />application: <br />C. <br /> Table 3 – Montage II – Post Spacing By Bracket Type <br />Span For INVINCIBLE® <br />8’ Nominal (91-1/2” Rail) <br />For CLASSIC, GENESIS, & MAJESTIC <br />8’ Nominal (92-5/8” Rail) <br />Post Size 2-1/2” 3” 2-1/2” 3” 2- <br />1/2” <br />3” 2- <br />1/2” <br />3” 2-1/2” 3” <br />Bracket <br />Type <br />Industrial <br />Flat Mount <br />(BB301)* <br />Industrial <br />Line <br />2-1/2” (BB319) <br />3” (BB320) <br />Industrial <br />Universal <br />2.5” (BB302) <br />3” (BB303) <br />Industrial <br />Flat Mount <br />(BB301) <br />Industrial <br />Swivel <br />(BB304)* <br />Post Set- <br />tings <br />± ½” <br />O.C. <br />94- <br />1/2” 95” 94- <br />1/2” 95” 96” 96- <br />1/2” 96” 96- <br />1/2” *96” *96- <br />1/2” <br />*Note: When using BB304 swivel brackets on either or both ends of a panel installation, care must be <br />taken to ensure the spacing between post and adjoining pickets meets applicable codes. This will require <br />trimming one or both ends of the panel. When using the BB301 flat mount bracket for Invincible style, <br />rail may need to be drilled to accommodate rail to bracket attachment. <br />D. When cutting/drilling rails or posts adhere to the following steps to seal the exposed steel <br />surfaces; 1) Remove all metal shavings from cut area. 2) Apply zinc-rich primer to thoroughly <br />cover cut edge and/or drilled hole; let dry. 3) Apply 2 coats of custom finish paint matching <br />fence color. Failure to seal exposed surfaces per steps 1-3 above will negate warranty. <br />Ameristar spray cans or paint pens shall be used to prime and finish exposed surfaces; it is <br />recommended that paint pens be used to prevent overspray. Use of non-Ameristar parts or <br />components will negate the manufacturer’s warranty. <br />E. Concrete Set Posts: Drill hole in firm, undisturbed, or compacted soil. Holes shall have <br />diameter four times greater than normal outside dimension of post and depths approximately 6” <br />(152 mm) deeper than post bottom. Excavate deeper as required for adequate support in soft <br />and loose soils and for posts with heavy lateral loads. Place concrete around post in a <br />continuous pout. Trowel finish around posts and slope to direct water away from posts. <br />1. Gate Posts and Hardware: Set keepers, stops, sleeves and other accessories into concrete. <br />F. Surface mount (wall mount) posts with mounting plates where indicated.
