About this detail

A light pole foundation is anchored to a steel pipe pile and encased in a twenty-four-inch diameter concrete bumper reinforced with welded wire fabric. The assembly incorporates an eight-inch standard steel pipe pile driven to a minimum depth of fifteen feet below finished grade into sandy-rocky soil. Electrical conduits sweep through a wide slot in the pile foundation to connect with buried runs. The light pole base plate secures to four anchor bolts sized to match the pole manufacturer specifications, while a twelve-gauge painted sheet metal cowling covers the anchor bolt assembly.

PILING SHALL BE STEEL, 8 INCH STD. ASTM A53 GR-B OR AS APPROVED. STRUCTURAL STEEL SHALL BE ASTM A36. WELDING SHALL BE PERFORMED IN ACCORDANCE WITH AMERICAN WELDING SOCIETY, (AWS) D1.1-86. PILE CONTRACTOR SHALL VERIFY UTILITY LOCATIONS AND OBTAIN CLEARANCE FROM THE OWNER PRIOR TO BEGINNING PILE DRIVING OPERATION. PILING SHALL BE DRIVEN TO A MINIMUM DEPTH OF 15 FEET BELOW THE FINISH GRADE INTO SANDY-ROCKY TYPE STRUCTURAL SOIL. PILING SHALL BE DRIVEN TO A VERTICAL TOLERANCE OF 1/4' PER 10 FEET OF VERTICAL AND TO A HORIZONTAL TOLERANCE OF 1 INCH. SPLICES IN THE PILING PIPE SHALL BE MADE USING A QUALIFIED WELDING PROCEDURE IN ACCORDANCE WITH ASTM B31.1 USING P3 PROCEDURE (7018 ROOT 7018 INTER AND CAP). CONCRETE SHALL ATTAIN A 28 DAY COMPRESSIVE STRENGTH OF 2500 PSI. WELDED WIRE FABRIC SHALL CONFORM TO ASTM A185. REFER TO SITE PLAN ON SHEET E-101 FOR JUNCTION BOX LOCATIONS.
