This marina replacement project included the relocation of 13 steel pile aids-to-navigation (ATON) along a two-mile entrance channel to the marina basin. NCI’s services included preparation of plans, specifications, bid documents, cost estimate, and performance of construction management and inspection to oversee the widening of this entrance channel. These ATON structures included piles, platforms, lanterns and ladders. A geodetic survey was required for the relocated ATON structures, with submittals to the National Geodetic Survey and the U.S. Coast Guard.
