Indian River County Page 2 <br /> Project No. 07- 10-2558 (BG 10. 1 ) <br /> • In-place density testing during backfilling of flexible and rigid pipelines . The density <br /> tests will be performed at a frequency of one ( t ) test location for every 200 lineal feet of <br /> pipe and at each road crossing for each I -foot of backfill placed. Density testing of pipe <br /> backfill will extend from an elevation corresponding to the invert of the pipe to the <br /> subgrade elevation. <br /> • In-place density tests within the stabilized subgrade and base course layers at a frequency <br /> of one ( 1 ) test for each 200 lineal feet of roadway. <br /> • Sampling, slump testing, molding, transporting, curing, and laboratory testing to <br /> determine the compressive strength of concrete used during construction. <br /> Laboratory Testing <br /> • Perform laboratory moisture-density relationship tests (AASHTO T- 180), sieve analysis, <br /> organic content tests, and Atterberg limits determination on the existing embankment <br /> soils and/or fill soils. <br /> • Limerock Bearing Ratio (LBR) tests for stabilized subgrade and base course at a <br /> frequency of one ( 1 ) test for each 1000 lineal feet of roadway or fraction thereof. <br /> Engineering & Repartilrp <br /> • Engineering oversight during construction to coordinate the aforementioned test program, <br /> make site visits, and attend progress meetings as needed . <br /> • Submittal of brief engineering reports documenting our findings and test results. <br /> TERMS AND PAYMENT <br /> We propose to bill this work on a unit rate basis in accordance with our current 2007-2008 <br /> Continuing Geotechnical Services Contract (IRC Project No. 0534). We understand this work <br /> will be performed under a purchase order number issued by Indian River County. <br /> Based on the described scope of work and testing frequencies, we have provided an Itemized <br /> Cost Breakdown (Attachment A) for the required services and established an estimated budget of <br /> $96,430. Attachment B contains our Indian River County Continuing Geotechnical Services Fee <br /> Schedule and Attachment C is our Project Data Sheet. <br /> 000 <br /> Umikelberaer <br />
