Leiendecker; EIT <br />EXHIBIT <br />Subject: Proposal for Subsurface Soil Exploration_ <br />Proposed 45th Street Roadway Improvements <br />'431dAvenue to 60th Avenue " <br />Indian River County,. Florida <br />Ms. Leiendecker: . <br />As requested by Mr. Stephen E. Moler, P.E. with Masteller & Moler, Inc., we are pleased to submit our <br />proposal to 'perform a. subsurface soil . exploration and pavement coring. services .,for ,the above . <br />referenced project. The purpose of this, work is to.obtain general subsurface soil information .for the <br />use of.project design engineers. <br />PROJECT UNDERSTANDING <br />It. is our understanding that this segment of '45th' Street will be designed for various roadway and <br />drainage, improvements. The number and approximate location of soil borings and pavement cores <br />were presented to us on a Soil Boring & Pavement Core Location. Exhibit dated June 5,:.20.18 which <br />Was provided to us by Mr. Moler. <br />FIELD EXPLORATION <br />As requested, we propose the following feld'program:, <br />Borings . <br />and Type: <br />Depth (feet) <br />Location Description <br />Locations representative Of ,a .given roadway segment and surface <br />13 SPT . <br />15 <br />condition and'conducted between the south edge of pavement and <br />the adjacent drainage ditch.. <br />Proposed mast arm foundations or strain poles for traffic signals at: <br />4 SPT...:. <br />35 . <br />intersections of .43rd Avenue. and:, 58th Avenue. Two borings" per <br />intersection at opposing corners where possible. <br />The borings will be performed with truck -mounted drilling equipment in general accordance with .the <br />procedures recommended in ASTM . D-1586. . Please note that many of these boring locations will <br />require temporary lane closures of the eastbound lane of 45th Street and associated Maintenance -of - <br />Traffic (MOT). <br />In addition, we will also perform seven (7) pavement cores at therequested locations within, 45th Street. <br />The. thicknesses of the ;existing asphalt and pavement base material will be measured and recorded <br />at each location. The:pavement core locations will be positioned in areas of. observeddistress where <br />possible. Coring of. the .roadway will require temporary lane .closure of.the eastbound lane of '45th <br />Street and :associated Maintenance -of -Traffic. (MOT), The ' core holes .will be backfilled with <br />accumulated base material and patched with.cold-patch asphalt upon completion:. <br />460 NW Concourse Place, Unit 1, Port St. Lucie, Florida 34986 Phone (772) 878-0072 FAX 02) 878-0076 <br />Louisiana: Alexandria, Baton Rouge, Monroe, New Orleans, Shreveport <br />Florida: Bartow, Cocoa, Fort Myers, Miami, Orlando, Port Charlotte, Port St. Lucie, Sarasota, Tallahassee, Tampa, West Palm Beach <br />
