Precast Concrete Piles

[MrBridges]

I am currently investigating the use of precast concrete piling for a bridge foundation. I was wondering if anyone knows where I can find details for pile tips for precast piles, and also if anyone has experience driving precast piles in areas where we might encounter cobbles and boulders...

Mafco, HMC, and APE all have good pile driving information of their websites. The rule of thumb when driving precast pile in the vicinity of boulders and cobbles is - don't.
