Changes to dune conditions since original designs were completed in the fall of 2023 may require both additional design costs, and changes to material quantities for the north and middle dune crossovers. Additionally, the bid documents anticipated a notice to proceed on February 1, 2024, however, permits are not expected to be approved prior to the beginning of sea turtle nesting season, which runs from March 1, 2024 through October 31, 2024, and during which no construction may take place. The delay in the commencement of construction could lead to a potential increase in material costs. In order to ensure successful reconstruction of at least the southern, most -highly utilized boardwalk, staff suggests the Board authorize the Administrator to exclude one or both of the northern crossings from the current project, if necessary, after coordination with the contractor, Federal Emergency Management Agency (FEMA), and the Florida Department of Environmental Protection (FDEP). Staff anticipates the contractor will be able to complete the demolition portion of the southern crossing prior to, or during the early, less - active, turtle nesting period, and construction of the new southern crossing to commence November 1, 2024. If conditions and prices are stable through turtle nesting season, and the two northern crossings can be constructed as bid, staff would plan to move forward with them beginning November 1, 2024, as well.
