Dear Bob, I'm researching for a new home I plan to construct in Bayville NJ on Barnegat Bay. We'll need pilings for a foundation. What can you tell me about the process of installing wood pilings, ( how far on center) etc. The house will be a modular. Do you recommend Hardie-Plank or similiar concrete products for siding? Also, what do you know about CAFRA and other DEP permits for bayfront building? I intend to GC myself.
