Short answer

Index 455-101 is the FDOT Standard Plan for Series Square CFRP & SS Prestressed Concrete Piles, part of Series 455 (Structures). The sections below are extracted from FDOT's Standard Plans Instructions (SPI) for this index — design criteria, assumptions and limitations, and what your plans must show.

Design Criteria

Design Criteria AASHTO LRFD Bridge Design Specifications ; Structures Detailing Manual ( SDM ) ; Structures Design Guidelines ( SDG ) ; Fiber Reinforced Polymer Guidelines ( FRPG )

Design Assumptions and Limitations

Design Assumptions and Limitations Index 455 - 1 0 1 is the lead standard for the Square CFRP & SS Prestressed Concrete Pile standard series which includes Indexes 455 - 1 0 1 through 455 - 1 30. Use this standard with Indexes 455 - 102 , 455 - 003 , 455 - 1 12, 455 - 1 14, 455 - 1 18, 455 - 1 24 and 455 - 1 30. Standard piles are designed to have 1000 psi uniform compression after prestress losses without any applied loads to offset tensile stresses that occur during typical driving.

The piles are designed to have 0.0 psi tension using a load factor of 1.5 times the pile self - weight during pick - up, storage and transportation as shown in the "Table of Maximum Pile Pick - Up and Support Lengths" on the standard.

What your plans must show

Plan Content Requirements for this index — the SPI's checklist for designers.

In the Structures Plans: Show and label the piles on the Foundation Layout, End Bent, Intermediate Bent, Pier, Footing, Typical Section and other sheets as required. Complete the following "Data Table" in accordance with SDG 3.5 and SDM 11.4 and include it in the contract plans with the "Foundation Layout" sheets. Modify table and notes as required to accommodate the required number of piles, piers and/or bents, use of Test Piles and instrumentation. When not enough space is available on one plan sheet, continuations of the Data Table and/or separate pile cut
- off elevation tables are acceptable. See FDM 115 for more information regarding use of Data Tables. For projects without Test Piles change data table column heading "TEST PILE LENGTH (ft.)" to "PILE ORDER LENGTH (ft.)".

How PDFDepth uses this index

When a plan set cites Index 455-101, PDFDepth's AI Plan Review cross-references the set against the Plan Content Requirements for the FDOT indexes it cites and flags items that appear to be missing — each with a citation to the sheet. A human reviewer verifies every flag before it counts.
