Attachment A — SCOPE OF WORK Project Name: Indian River County FWC Agreement No. 18101 Artificial Reef Construction 2018-19 1. DESCRIPTION OF GOODS / SERVICES PROCURED, OR PROJECT WORKPLAN A. DESCRIPTION OF GOODS / SERVICES The objective of this activity is to construct a marine artificial reef by deploying at least 500 tons of concrete culverts, clean concrete riprap, concrete road barriers, limestone boulders or other suitable concrete construction materials, as well as at least 10 reef modules at least eight feet tall in two patch reefs within the Orchid Island Artificial Reef Complex permitted area located in the Atlantic Ocean 5 nm bearing 110° from Sebastian Inlet. Each patch reef will consist of the aforementioned artificial reef materials placed into two designated locations within the boundaries of the permitted area (SAJ-2016-02916) at a depth of 50-56 ft. The artificial reef construction activity to be funded consists of the following elements: MATERIALS 1. Artificial reef materials must consist of a total of at least 500 tons of clean secondary - use concrete material, and at least 10 pre -fabricated concrete reef modules deemed acceptable to the COMMISSION. All artificial reef materials shall be clean and free from excess dirt, asphalt, creosote, petroleum, or other hydrocarbons and toxic residues, loose free floating material or other deleterious substances. All 10 reef modules must be at least 8 feet tall with a base diameter of at least 10 feet and weigh at least 2 tons. 2. Individual secondary -use artificial reef materials shall weigh a minimum of 500 lbs. and measure a minimum three feet in diameter. The GRANTEE shall evaluate the structural integrity of each concrete unit proposed for use, and shall eliminate from artificial reef material consideration all fragile material that would be prone to break apart into pieces less than 500 pounds in weight during the handling and transport process. Reef material with extensive exposed rebar will either be eliminated from consideration or the rebar will be cut back by the selected contractor as close to the concrete surface as possible, within six inches or less of the units' concrete surface prior to transport. 3. Pre -fabricated modules must be composed of marine grade concrete with a minimum strength of 4,000 pounds per square inch (psi). Pre -fabricated modules shall consist of concrete with no exposed metal framework. Pre -fabricated modules will be designed with multiple openings of various sizes all the way through the outer surface to allow for water circulation and access by fish. 4. Open -bottom pre -fabricated reef modules may not be used unless the module has a top opening sufficiently large to allow for turtle escapement. Approved open -bottom modules include: a. Three -sided modules where each side of the top opening is at least 36 -in in length along its edge. b. Four or more sided modules where each side of the top opening is at least 40 -in in length along its edge. c. Modules with a round opening with a diameter of at least 40 -in (oval openings are not allowed unless a 40 -in diameter circle space can fit within the oval).
