ATKINS investigation is to delineate the distribution sea grasses prior to demolition operations. The objective of the debris mapping is to develop an inventory and location map of the submerged debris for use in preparation of the demolition plans and bid documents. Location information will be collected using a handheld GPS unit capable of sub meter accuracy. Locations will be considered approximate, and are not intended to be considered a formal survey meeting the State's Minimum Technical Standards. These field data collection services shall include the following tasks: A. The sea grass survey will cover an area of approximately eleven acres, roughly described as follows. o Bounded on the northwest by the highway bridge o Extending southwest of the highway bridge approximately three -hundred feet o Running the length of the highway bridge (approximately 1,300 feet. o Including the area around the boat ramp B. The debris mapping will cover the areas directly adjacent to the damaged pier sections, roughly described as follows. o A 100' by 30' area covering the two damaged spans on the west pier o A 300' by 45' area covering the six damaged spans on the east pier C. A brief report discussing the findings of the seagrass survey and debris mapping will be prepared. The report will include maps of the submerged resources and the debris field, and the mapped information will also be used in the demolition plans. TASK 2: PRELIMINARY PLANNING The Engineer shall develop a preliminary demolition plan to meet the County's intended purpose while following generally accepted engineering standards and anticipated permitting requirements. The planning and construction document preparation services shall include the following tasks: A. Participate in one meeting with the County to facilitate the planning process. The meeting shall be held at the project site or the County's offices. The following is the anticipated meeting: o Draft preliminary plan review meeting B. Conduct phone inquiries with up to three marine contractors to gather information on expected contractor means and methods for use in demolition planning and permitting. C. Conduct phone inquiries with USACE and FDEP to assess likely permitting mechanisms and requirements. D. The Engineer shall make one plan submittal to the County during the design development process. Following the completion of the kickoff meeting, and field data collection, the Engineer shall prepare a preliminary plan set. This plan set shall contain a level of detail and information typically required for the FDEP and USACE permitting process. It will also contain a level of detail sufficient for preparing a cost estimate to be used in the FEMA funding pursuit. The preliminary plans set will be produced in 8'/ x 11 size to meet permitting agency requirements, and in a manner that will facilitate scaling up to 17 x 22 size for easier review. A preliminary opinion of probable cost will be prepared upon the completion of, and included with, the preliminary plan set. The County will have the opportunity to review and comment on the preliminary plan set. The Engineer will incorporate reasonable comments into the plan set. 05 JUN 2017 Page 2 of 3
