Sector 3 Beach & Dune Restoration Project Attachment 1 to Change Order No . l <br /> upon ASTM D 422 . Required U . S . Standard sieve sizes include 3 /4 " , 5 / 8 " , <br /> 11 / 16 " , 5 / 16 " , 3 . 5 , 45 5 , 7 , 10 , 14 , 18 , 25 , 355 45 , 605 80 , 120 , 170 , 200 , and <br /> 230 . <br /> The following parameters shall be reported for each sample : <br /> (a) mean grain size (mm & phi ) , <br /> (b) Carbonate Content — determined by Loss on Ignition <br /> (c) Silt Content - weight percent of fines passing the #200 sieve , <br /> (d) Gravel Content - weight percent of gravel (>_#4 sieve) , <br /> (e ) Munsell Color (dry & moist) <br /> (f) weight percent of sand (retained between 4200 to 44 sieve) , <br /> (g) presence of construction debris or other foreign matter, and <br /> (h) Unified Soil Classification . <br /> 3 . Recording and Reporting Results - The results of each sample analysis <br /> shall be submitted as follows : <br /> (a) tabular stunmary the parameters enumerated above (a thru h) , <br /> (b) a statement indicating whether or not the sample meets or fails the <br /> Project Standards — identified in Table 2 above , <br /> (c) grain- size cumulative frequency distribution curve (a. k . a. gradation <br /> curve) with a grain - size frequency distribution histogram <br /> superimposed , <br /> (d) tabular summary of nested sieve sample granularmetrics . <br /> All geotechnical data must be submitted in a format compatible with data entry <br /> into the FDEP ROSS database . These results must be submitted to the <br /> ENGINEER within 7 working days of sample collection . The submittal date shall <br /> be recorded by the laboratory on all reporting documents . The CONTRACTOR <br /> will submit the results of all sample analyzes to the COUNTY within 7 days of <br /> the sampling date . The COUNTY <br /> will submit the results of all sample analyzes to FDEP within 90 days of <br /> completion of sand fill placement . <br /> VIII . CONTRACTOR Duties <br /> A. The characteristics of the in - situ materials in the beffow afeas and alternate <br /> upland sand sources ares generally indicated by the boring logs and grain size <br /> distribution curves , included within Appendix PFI of the Design Document Addendum <br /> (revised : 11 /24/09) with the characteristics of the proposed "processed sand" fill--Fof <br /> data, , <br /> Restoration Projeet, Design " Nevertheless , the <br /> CONTRACTOR should be aware that it is possible for material of differing <br /> characteristics to be present in the borrow area and that the mining process may <br /> correspondingly require revisions to produce beach compatible sand consistent with the <br /> criteria cited above . For the offshore barfow afea, <br /> Digs. Limits of excavation for upland sand sources (a) are to be determined based <br /> upon the information provided by the CONTRACTOR to fulfill the Geotechnical <br /> Requirements , and (b) are subject to approval of the ENGINEER. <br /> Page 20 of 26 <br /> March 16, 2010 <br />
