Design & detailing notes
- P12S uses a circular strand pattern and spiral. P20S and P24S use square strand patterns with spiral reinforcing per design requirements.
- For P20S and P24S, standard cover to spiral is 3 in; the sheets describe a possible reduction to 2 in for non-marine applications where appropriate for reinforcing requirements.
- The P12S sheet specifies 2 in cover and notes that this section is generally not recommended for marine applications.
- Potential strand locations are illustrated; final strand counts depend on design prestressing demand. Slight side draft may be used for stripping.
- The same PDF also includes P20F and P24F fender-pile insert details.
