1. FENCE: THE FENCING MATERIAL AND INSTALLATION MUST MEET ASTM F2611-15

UNLESS OTHERWISE SPECIFIED ON THESE DRAWINGS, THE MORE STRINGENT MUST

APPLY. FOR EXAMPLE: END, CORNER, AND PULL POST DIAMETERS ARE LARGER ON

THE DRAWINGS THAN ASTM F2611-15 REQUIRES.

2. FABRIC: THE STANDARD FENCE FABRIC MUST BE VINYL, ZINC, OR

ALUMINUM-COATED STEEL WIRE CHAIN LINK WITH MESH OPENINGS NOT LARGER

THAN TWO INCHES PER SIDE AND A TWISTED AND BARBED SELVAGE AT TOP AND

BOTTOM IN ACCORDANCE WITH ASTM A392-11a FOR BASE PERIMETER OR

HEIGHTENED SECURITY ZONES. UTILIZE 6-GAUGE FOR BASE PERIMETER OR

HEIGHTENED SECURITY ZONES AND 9-GAUGE FOR BASE INTERIOR OR WHEN JOINING

AN EXISTING FENCE WHICH IS ALREADY 9-GAUGE. AFTER THE FABRIC INSTALLATION

IS COMPLETE, EXERCISE THE FABRIC BY APPLYING A 50 LB PUSH-PULL FORCE AT

THE CENTER OF THE FABRIC BETWEEN POSTS. THE USE OF A 30 LB PULL AT

THE CENTER OF THE PANEL MUST NOT CAUSE FABRIC DEFLECTION OF MORE THAN

2.5 INCHES WHEN PULLING FABRIC FROM THE POST SIDE OF THE FENCE. EVERY

SECOND PANEL MUST MEET THIS REQUIREMENT. RESECURE AND/OR ADD BRACING

AND RETEST ALL FAILED PANELS AT THE CONTRACTORS EXPENSE. (UFGS 32 31

13.53)

3. FITTINGS AND FABRIC TIES: ALL GALVANIZED FITTINGS, FABRIC TIES AND HOG RINGS

MUST CONFORM TO ASTM F626-14 AND ZINC COATED PER ASTM-A153-16a. ONLY

9-GAUGE STEEL FABRIC TIES MUST BE USED. COATING OR PLATING WILL BE

ELECTROLYTICALLY COMPATIBLE WITH THE FENCE FABRIC TO INHIBIT CORROSION.

4. TENSION WIRE: TENSION WIRES MUST BE INSTALLED ON SECURED SIDE OF THE

FENCE AND AFFIXED WITH FABRIC TIES OR HOG RINGS ALONG THE TOP & BOTTOM

OF THE FENCE FOR STABILIZATION OF THE FENCE FABRIC. METALLIC COATED

STEEL MARCELLED TENSION WIRE MUST BE 7-GAUGE MINIMUM TYPE-II CLASS 5

(2.0 OZ/SQ.FT) ZINC COATED IN ACCORDANCE WITH ASTM-A824-01. TOP AND

BOTTOM TENSION WIRE MUST BE WITHIN 8 INCHES OF THE EDGE OF FABRIC ON

THE TOP AND BOTTOM.

5. BARBED WIRE: 3 OR 6 STRANDS , WHICHEVER IS SPECIFIED, OF METALLIC COATED

STEEL BARBED WIRE MUST COMPLY WITH ASTM A121-13 DESIGN NUMBER

12-4-5-14R COATING TYPE Z CLASS 3.

6. FENCE HEIGHT

AN ADDITIONAL 1' IN HEIGHT COMPOSED OF 3 OR 6 STRANDS OF BARBED WIRE,

7. GROUND CLEARANCE: BOTTOM OF THE FENCE FABRIC MUST BE WITHIN TWO

INCHES OF FIRM SOIL.

8. DOUBLE EXTENSION ARMS: A DOUBLE EXTENSION ARM IS AN OVERHANG OF

BARBED WIRED ALONG THE TOP OF A FENCE, FACING OUTWARD (AWAY FROM

PROTECTED SITE) AND UPWARD AT APPROX. 45 DEGREE ANGLE. DOUBLE

EXTENSION ARMS MUST INCREASE THE OVERALL HEIGHT OF THE FENCE AT LEAST 1

FOOT FOR A TOTAL HEIGHT OF 8 OR 10 FEET AS SHOWN. DOUBLE EXTENSION

ARMS MUST BE PERMANENTLY AFFIXED TO THE TOP OF FENCE POSTS WITH BLIND

RIVETS FROM THE PROTECTED SIDE OF THE FENCE TO AVOID TAMPERING FROM THE

ATTACK SIDE OF THE FENCE. SIX STRANDS OF 12-GAUGE BARBED WIRE, EQUALLY

SPACED, MUST BE INSTALLED ON THE DOUBLE EXTENSION ARMS.

9. FENCE POSTS, RAILS, AND BRACES: MUST BE ASTM F1043-18 GROUP IC ROUND

STEEL PIPE AND MUST BE GALVANIZED IN ACCORDANCE WITH THE SPECIFICATIONS.

SIZE (DIAMETER) MUST NOT BE LESS THAN THAT SPECIFIED BELOW. POSTS MUST

BE PLUMB IN CONCRETE FOOTING IN ACCORDANCE WITH ASTM F567-14A. TOP OF

9.1. POST SIZE:

FOOTING DIA. - 12"

CONCRETE - 4000 PSI

FOOTING DIA. - 16"

9.2 POST SPACING: FENCE POST SPACING MUST NOT EXCEED 10'-0" OC OR AS

INDICATED ON THE DRAWINGS. MAXIMUM POST SPACING OF 10'-0" OC WILL

BE STRICTLY ENFORCED. POST SPACING MUST BE SHORTENED ALONG GRADES

SUCH THAT NO MORE THAN 2'-0" OF ELEVATION CHANGE OCCURS BETWEEN

POSTS. FENCE POST SPACING AND SIZE (DIAMETER) MUST BE DETERMINED IN

10.
