Although it appears that <br /> -AX0916)=-4530 you attempted to get crnnparable-bids fur this wank,the submitted proposals are not comparable(either the <br /> NrnF9 Wide Web <br /> consultant did not vlclude all of the proposed work or have added work,or they have varied the mmiber and <br /> 44,3Z 9"ct'.U. type of analytical testa). Based on my review,the Geological Technics appears to be the low ptnptlsat; <br /> 9orr c„*-mW however,some o£the ousts apparr high and/or more explanation of the chats are needed. Cutrendy, I am <br /> &WIN4=2.hha able to pre-approve$26,394 of the Geological Technics proposal totaling, $29,145 subject to the following <br /> Provisions: <br /> • Your claim is found eliole for the Fund and issued a letter of Coat for fltmding. <br /> • The submitted approved work pin stated that 5.20'borings and 3-30'wells were to be installed. The <br /> Gealagical T clutics bid proposal language indicates the same, However,the language in the cost <br /> bmalalown and the cost of the boring(f VEW)installation asdieatee that vapor extraction welts(vBWs) <br /> Will be hhstalle& Cunv*,r cam pre-approve a maximum of$17/toot$x the installatiom of the boring <br /> (S171t'oot wee ed). T'hia is a reduction of$2,000. Cos#for VLws installation wtll be coruidmd; <br /> however,the lee for the Wella must be established and it should be stated that the watk is to be <br /> conducted. <br /> • The groundwater unoe analyses(OW Monitor and Repartittg)proposed costs wore S98/sample for <br /> TPH wlrrEXM ME. This coat is higber than currently available. $9/sample is lm-approved(Shia is <br /> connateet with tis soil sample cost and rates commonly available for d us test,including=Wwp). <br /> I <br /> • The FM07*s drum nadir disposal costa at$165/dram. Ibis cost is higher thaw those typically <br /> available. y,only SUN==is pie-approved, <br /> • The actual costa Wd scope of work performed must be consistent with the p m gpmval for it to remain <br /> valid. If a dif&remt scope of wore becomes necessary,then you must request prampprovai of costa ort <br /> the,fewscope of ork, <br /> • Tbc work p;must be acceptable to the Regional Bowd(srd/or Local agency). <br /> • The three bid reguirem ant bas been waived for this pm epproval.
