The total strand pattern shall be concentric with the nominal concrete section of the pile. 2. CONTRACTOR OPTION: The 30" pile may be cast SOLID by omitting the 18" Ø void. In this event, the 12 ~ No. 10 Contractor shall submit calculations for approval and a proposed strand configuration that provide net prestressing after losses equal to 1000 psi. Alternate configurations for the Diagonal Ties, to maintain the position of the 4 ~ No. 8 Bars, may be approved by the Engineer. 1: 44: 18 PM 7 8" (10'-6" long) 1. Any of the given Alternate Strand Patterns may be utilized. The strands shall be located as follows: 4 ALTERNATE STRAND PATTERNS 3.
