IBI— - iates, Inc.Ardaman & Assoc � I i 1 \ ` Geotechnical, Environmental and Materials Consultants June 1 , 2007 Proposal File No. 07-5552 Indian River County Engineering Division 1840 25" Street Vero Beach, Florida 32960 Attention: Mr. Mike Mezzina Subject: Proposal for Soil Permeability Testing 101 " Avenue Extension Indian River County, Florida Dear Mr. Mezzina: As requested, we are pleased to present the following proposal for conducting soil permeability testing for the subject project. Based on information provided to us, we understand that the project includes stormwater retention swales along the proposed roadway extension . Shallow soil stratigraphy and permeability data and an estimate of the normal seasonal high groundwater table level are needed for the design of the swales. The following summarizes our proposed scope of work and associated fees for conducting the subject exploration . FIELD EXPLORATION As discussed , our field exploration program will consist of performing five auger borings to a depth of approximately 6 feet below ground surface . The boringswill be conducted using a 3-inch diameter hand (bucket) auger in the vicinity of the locations selected by the client. Each sample will be removed from the auger in the field and then examined and visually classified by ourfield personnel . Representative portions will be sealed and packaged fortransportation to ourlaboratory forfurther analysis as required. Water level observations will be made in the boreholes during the drilling operation. In addition, a shallow test pit will be excavated by hand adjacent to each of the boring locations to a depth ranging from approximately 1 to 3 feet. At the bottom of the test pit, a 3-inch diameter Shelby tube sample of soil will be obtained in a vertical orientation for permeability testing in our laboratory. A second Shelby tube sample will also be obtained from the sidewall of each test pit in a horizontal orientation. The boreholes and test pits will be backfilled with excavated material upon completion of the field program . LABORATORY TESTING Routine laboratory visual classification will be performed alongwith specificclassification tests -deemed necessary (i.e. , sieve analysis, Atterberg limits and organic contents). Constant-head laboratory permeability tests will be performed on the Shelby tube samples obtained from the test pits. 460 Concourse Place NW. Unit 1 , amort St Lucie . Florida 34986.
