We will peform a courtesy destop analysis from your site's existing data and tell you if we believe a Reef Ball Submerged Breakwater would be suitable for your location. If suitable, we will perform an on-site preliminary survey charging expenses plus professional fees. If you proceed to construction we'll credit the fees (less expenses) toward your project cost. A typical preliminary survey costs between $3,000-$10,000 depending upon location and site size and can usually be performed in 2-5 days.
