The 4.5 FS288BL2 Retrofit Bracket Assembly: The FS288BL2 brackets are manufactured from a 4.65-inch (118.1 mm) bracket assembly consists of an FS288BL2 bracket, an long,3'/z-inch(89 mm)OD by 0.250-inch(6.4 mm)nominal external pipe sleeve(FS288ES30)a cap plate(FS288C),two wall thickness steel pipe sleeve with a factory-welded 3/4- threaded rods and matching nuts. The assembly is illustrated inch thick (19.1 min) steel cap plate. The cap plates are in Figure 1 of this report. either 6-inch(152 mm)square(HP288NCB)or 8-inch(203 mm) square (HP288NCB8). The steel plate conform to 4.5.1 FS288BL2 Brackets: The FS288BL2 bracket is ASTM A36 with a minimum yield strength of 36 ksi (248 constructed from factory-welded, 0.250-, 0.3125-, 0.375-, MPa) and minimum tensile strength of 58 ksi (400 MPa). and 0.500-inch-thick (6.35 min, 7.94 mm, 9.53 mm, and The pipe sleeves conform to ASTM A513, Type 5, DOM, 12.7 mm) steel plates. The steel plates conform to ASTM Grade 1026 having a minimum yield strength of 70 ksi(483 A572, Grade 50, with a minimum yield strength of 50 ksi MPa) and a minimum tensile strength of 80 ksi(552 MPa). (345 Mpa) and a minimum tensile strength of 65 ksi (448 The bracket finish is plain steel or hot-dip galvanized in Mpa).The bracket finish is plain steel or hot-dip galvanized accordance with ASTM A123. The assembly is illustrated in accordance with ASTM A123. in Figure 2 of this report. 4.5.2 FS288ES30 External Sleeve: The external sleeve 6.0IDENTIFICATION (FS288ES30) is manufactured from a 30-inch-long (762 mm), 31/2-inch outside diameter (89 mm) and 0.216-inch Supportworks helical foundation systems are identified by (5.49 mm) nominal wall thickness pipe conforming to the report holder's name, Supportworks, Inc., the ASTM A500, Grade B or C, having a minimum yield manufacturing location identifier, helical foundation model strength of 50 ksi(345 Mpa)and a minimum tensile strength name, and evaluation report number- (ER-691). The of 62 ksi (427 Mpa). One end of the external sleeve has a identification also includes the IAPMO Uniform Evaluation 1.00-inch long(25.4 mm)section trumpeted to a final outer Service Mark of Conformity as shown below: diameter of 4.00 inches (101.6 min). The sleeve finish is plain steel or hot-dip galvanized in accordance with ASTM A123. IA 4.5.3 FS288C Cap Plate: The FS288C cap plate ,is P M p U E S produced from a 1-inch-thick(25.4 mm),4-inch-wide(102 E S mm), 8.25-inch-long (210 mm) steel plate. The plate complies with ASTM A572, Grade 65,having a minimum or yield strength of 65 ksi (448 MPa) and a minimum tensile strength of 80 ksi(552 MPa).The cap plate assembly finish IAPMO UES ER-691 is plain steel or hot-dip galvanized in accordance with ASTM A123. 4.5.4 Threaded Rod and Nuts: The cap plate is connected to the bracket with two 3/4-inch-diameter by 16-inch-long (19.1 mm by 406 mm)threaded rods,and matching 3/4-inch (19.1 mm)heavy hex nuts.The 3/4-inch-diameter(19.1 mm) steel threaded rods conform to ASTM A193, Grade 137, having a minimum yield strength of 105 ksi(724 MPa)and a minimum tensile strength of 125 ksi (862 MPa). The matching 3/4-inch-diameter(19.1 mm) steel heavy hex nuts conform to ASTM A563 Grade DH or DH3,or ASTM At 94 Grade 2H. The threaded rods and nuts are zinc-coated in accordance with ASTM 13633, with coating classification Fe/Zn 8. 4.6 HP288NCB and HP288NCB8 New Construction Brackets: The HP288NCB and HP288NCB8 new construction brackets are fastened to the top of the helical Page 4 of 7
