Ardaman & Associates , Inc . EX H I B IT " All <br /> January 31 , 2007 <br /> Proposal File No . 07-64-3147 <br /> Indian River County <br /> Board of County Commissioners <br /> Engineering Division <br /> 1840 25" Street <br /> Vero Beach , Florida 32960-3365 <br /> Attention : Mr. Michael D . Nixon , P . E . <br /> Subject: Proposal for Subsurface Soil Exploration and !i ti/ v <br /> Geotechnical Engineering Evaluation <br /> 8" Street Bridge at 74`h Avenue FEB 0 2 2007 <br /> Indian River County, Florida <br /> INDIAN HIVER '3OUNTY <br /> Gentlemen : ENGINF € RWG D; VIISIOPJ <br /> As requested , we are pleased to present the following proposal for conducting a subsurface soil <br /> exploration and geotechnical engineering evaluation forthe subject project. This proposal presents <br /> our approach to the project which was discussed with your project structural engineer, Bridge <br /> Design Associates , Inc. and includes an estimate of field exploration and laboratory testing <br /> quantities as well as geotechnical engineering services needed for the evaluation of the data <br /> obtained and preparation of a report. <br /> We understand that the project will consist of replacing the existing 8" Street bridge with a new <br /> bridge supported on prestressed driven concrete piles . <br /> The following summarizes our proposed scope of work and associated fees for conducting the <br /> subject exploration . <br /> FIELD EXPLORATION <br /> As requested , our field program will include conducting two Standard Penetration Test (SPT) <br /> borings , one at each end of the proposed bridge to a depth of 60 feet . The borings may be <br /> completed to shallower (or deeper) depths depending on the soil conditions encountered during <br /> the performance of the borings . The SPT borings will be drilled using a procedure similar to the <br /> Standard Penetration Test outlined in ASTM D- 1586 . The borings will be sampled at 18-inch or <br /> 24-inch intervals to 10 feet deep and at 5 -foot intervals below 10 feet. Each sample will be <br /> removed from the sampler in the field and then examined and visually classified by our crew chief. <br /> Representative portions will be sealed and packaged for transportation to our laboratory for further <br /> analysis as required . Water level observations will be made in the boreholes during the drilling <br /> operation . <br />
