It's not that tough to set up a pair of builders transits at roughly right angles to the point, and use those to control the position. I'm sure there are other High-Tech methods but that seems the simplest.

Fellow Engineers,

I’m working on a timber pile foundation design for a modular home. The front half is located above water ( Delaware Bay ) and the rear half on a bulkheaded sandy lot. Because it’s a modular, I’m specifying tight tolerances on pile center locations. Although not responsible for driving the piles, I suspect I’ll be asked how to locate piles in the water 30 ft away from the bulkhead. At low tide there may be 3 or 4 ft of water. Besides a surveyor at the site, are there less expensive ways?

Thanks

Irv
