3. In cases where pile splices are desired due to length limitations in shipping and/or handling, the "Drivable Preplanned Prestressed Precast Splice Detail" shall be used.
Mechanical Pile Splices contained on the Qualified Products List (QPL) may also be used.
4. When preformed dowel holes are utilized, the 1" spiral tie pitch shall be continued to 4’-0" below the head of the pile, See Index Nos. 20618, 20620 & 20624. Preformed
holes shall utilize either removable preforming material or stay-in-place corrugated galvanized steel ducts. Stay-in-place ducts shall be fabricated from galvanized sheet

NOTES:
Form to retain
steel meeting the requirements of ASTM A653, Coating Designation G90, 26 gauge. Ducts shall be 2" diameter with a minimum corrugation (rib) height of 0.12 in. Ducts shall
