With all due respect to Mr Thomas, he has been preaching for the past 5 years that half of Marco's seawalls will need to be replaced in next 5 years. He seems too self serving on his predictions. As far as precast or cast onsite, cast offsite is predicted to be less costly for lots that don't have an adjacent empty lot. If empty lots are not available for one reason or another, all the work at an existing lot with a house, will need to be done from the waterside anyways and new panels need to be replaced by barge. That adds a LOT to the overall cost, as compared to using ground based equipment. Sheet piling on outside and use of riprap is still the least costly way to extend life of an existing seawall.
