the overall magnitude of the project and the alongshore distribution of the fill templates will be considered. Avoiding hairdbottom impacts will expedite the permitting process and reduce the needed for mitigation. Storm protection benefits afforded by the project will be evaluated by using the SBEACH model. The calibrated SBEACH model setup from analyzes performed as part of the 2014 update to the County's Beach Preservation Plan will be utilized. Numerical modeling (i.e. Delft3D) in not included in this proposal. If numerical modeling is deemed necessary in evaluating the project and CB&I's services are requested, i separate work order will be proposed to the County. A feasibilityi analysis will be performed to evaluate potential upland sand borrow sources to be utilized for fill material. The analysis will evaluate various upland sand sources to identify the most economical and cost effective option. The upland sand sources, including those utilized for construction of the initial Sector 3 Beach Restoration Project and the Sector 3 Dune Repair Project, will be considered as they have been previously approved by the FDEP for grain size, color, and carbonate content. The presence of hardbottom resources and the minimization of impacts will likely limit the volume of sand that can be placed to construct the project. As a result, it is not anticipated that the size of the project will facilitate the use of offshore borrow areas. If offshore borrow areas are deemed viable and CB&I's services are requested in evaluating the borrow areas, a separate work order will be proposed to the County. Additional services not included in this scope of work may include, but are not limited to, reviewing areas previously identified and permitted by the County to determine the volume of beach compatibleisand available and their future viability, development of permit sketches, collect bathymetric surveys, and perform geotechnical investigations. The fill volt mes and upland sand borrow sources will be used to estimate construction costs and durations. The construction timeline will consider sea turtle nesting season and expected permit conditions. Deliverables CB&I will provide the County an electronic copy of the draft feasibility report for the County's review and comments. One (1) hard copy and one (1) electronic copy of the final feasibility report will be provided. Schedule The design' and evaluation of the potential options for Sector 5 project area will begin upon receipt of a notice -to -proceed. It is anticipated that 60 days will be required to complete the analysis and compose a feasibility report documenting the findings. At such time, a draft report will be provided to the County for its review and comments. Once the comments are returned to CB&I, the, final report addressing the comments will be submitted to the County within 15 days. Cost The cost to analyze the project area and compose a feasibility report is $32,248.00. A breakdown of the hours and expenses to develop these costs is attached and follow the terms of CB&I's agreement with Indian River County. 196
