5. Prepare an Engineering base plan (CAD drawing) of existing conditions along the route of A -1-A, incorporating the information and drawings obtained or created via steps 1-4 above. Task 2: Preliminary Enizineeriniz — Re -use main route: 1. Evaluation of Base map and determination of best route for the new re -use transmission main and distribution main network. 2. Obtain geotechnical data — soil borings along the route of the main, and at select locations where improvements may be proposed. 3. Prepare preliminary construction plans of the route of the main(s). Plans will depict the new re -use transmission main, distribution main(s), and stubbed -out service locations, from CR510 to Old Winter Beach Road. 4. Prepare preliminary construction cost estimate for the placement of the mains along the route, from CR510 to Old Winter Beach Road. The estimate will include costs based on an assumption that the Transmission main is 16" dia. to Sea Oaks WWTP, and the distribution main is 12" from Sea Oaks WWTP to Old Winter Beach Road, and 2" to 6" dia. stub -outs with valves at potential re -use customer service locations (12" stub -out at A). 5. Prepare preliminary report of findings — the objective is to determine if the construction of a large diameter re -use transmission main is possible and feasible along the SR A -1-A ROW. Task 3: Preliminary Engineering — Hydraulic Model/ system recommendations/ Final report 1. Evaluation of the service area, prepare an estimate of current and future re -use water (irrigation) needs. Prepare hydraulic analysis/model of the IRCDUS re -use water system proposed to service this area to determine and make recommendations for the system components, including the re -use main size(s), pump station(s) and storage tank(s), and other system infrastructure. 2. Prepare revised preliminary construction plans of the route of the mains, edited based on results of the modeling efforts. 3. Prepare revised construction cost estimate — edit estimate based on results of the modeling efforts and adding costs for storage tank and pump station at Sea Oaks WWTP. 4. Prepare the Final Report discussing the feasibility to run new Re -Use Water Mains south on SR A -1-A, from CR 510 to Old Winter Beach Road, and provide preliminary recommendations on the size and location of the re -use water transmission main and distribution mains in SR A -1-A and providing size of storage tanks and pumping station(s) located in Sea Oaks WWTP site. See Exhibit "A" for location map and conceptual plan. In connection with this project, Indian River County will provide the Engineer with a copy of any pertinent preliminary data or reports, all available drawings in electronic AutoCad format; all surveys, maps, record drawings and design drawings and other documentation in the possession of or reasonably available to the County that are pertinent to the project. In order to execute this project in the most cost-effective manner with the most aggressive schedule, Schulke, Bittle & Stoddard, L.L.C. is using the following sub -consultants:
