This proposal is <br /> cavsr�ucr,on, based on taking 110 - 31-feet deep soil borings. 110 borings should be an <br /> OUAClTYCONrROI adequate number of borings for most of the proposed sites. Our proposal is <br /> SOlLS/MA7ERlALS based on 31-feet deep borings, because it is our understand+ng that this <br /> TESTING site is to become a permanent storage facility with bermed walls at least 16- <br /> feet tall. Additionally, we have included a lump sum of $5,000 to provide a <br /> Geotechnical Report for two (2) mobilization sites. <br /> Our proposal includes providing soil boring logs and laboratory analysis of <br /> split-spoon samples taken at each boring. It also includes laboratory time <br /> to conduct additional tests such as shear strength, proctor and <br /> consolidation tests. From this information we will prepare a report with <br /> recommendations for the construction of the storage basin and the <br /> mobilization sites. Our proposal also includes time to attend monthly <br /> meetings throughout the project and prepare for and participate in public <br /> forums. <br /> We estimate the geotechnical investigation and report will take <br /> approximately two (2) months to complete. If you have any questions about <br /> this proposal, please contact Sharon Samuelson or me. We look forward to <br /> working with you on this project. <br /> Sincerely, <br /> SKS Engineers I c. <br /> � <br /> errel L.
