We use the CRSI's 2015 "Design Guide for Pilecaps" to design piles. There is an example in that design guide for a 6 pile condition. I have attached the table of contents for this design guide so you can see what the document includes (can't attach the full document since it is copyrighted). It is available for purchase at:
