FL 33431 <br />Tel: +1 561 391 8102 <br />Fax: +1 561 391 9116 <br />www.aptim.com <br />This proposal outlines a scope of work for Aptim Environmental & Infrastructure, LLC (APTIM), to provide <br />professional services to Indian River County (the County) in support of the Sector 3 Beach and Dune <br />Renourishment Project. The scope of work described herein is to support the County with permitting the Sector 3 <br />project. The tasks to perform this work are listed below and described on the following pages. A breakdown of <br />the hours and expenses to develop the cost is attached. The scope and fee was developed following the provisions <br />of the Professional Services Agreement between Indian River County and APTIM, dated January 9, 2018, to provide <br />engineering and biological support services for the Sector 3 (Wabasso Beach) Beach and Dune Renourishment <br />Project (RFQ#2018006). <br />The Florida Department of Environmental Protection (FDEP) has requested a reconnaissance level investigation <br />of the hardbottom resources in proximity to the Sector 3 project area. This includes potential resources along the <br />nearshore hardbottom edge, within 400 meters of the perimeter of the proposed borrow area, and within and 25 <br />meters adjacent to the proposed pipeline corridor(s). The following Scope of Work is proposed to gather this <br />information and satisfy the Department's request. <br />Task 1: Sidescan Sonar Survey <br />Task 1: Scope of Work <br />An EdgeTech 4125 sidescan sonar system will be used to collect sidescan sonar data over the entire area of <br />investigation. The 4125 sidescan sonar system uses full -spectrum chirp technology to deliver wide -band, high- <br />energy pulses coupled with high resolution and superb signal to noise ratio echo data. The portable sidescan <br />package includes a laptop computer running the Discover' acquisition software and a 600/1600 kHz dual <br />frequency towfish running in high definition mode. <br />The digital sidescan data will be merged with positioning data (Differential Global Positioning System (DGPS) via <br />Hypack), video displayed, and recorded to the acquisition computer's hard disk for post processing and/or replay. <br />The position of the sensor relative to the DGPS antenna will be documented to ensure proper positioning of the <br />data. <br />All sidescan sonar data will be processed using the SonarWiz software package developed by Chesapeake <br />Technologies Inc. This software package allows for advanced processing, interpretation, and digital mosaic output <br />
