City of Everett Point Industrial Center (EPIC) Bridge Project – Phase 2 Full Design <br /> <br /> Page 12 of 43 <br /> <br /> Geoenvironmental recommendations will be included within the geotechnical report and <br />no stand-alone geoenvironmental reports will be provided. <br /> Experience has shown that subsurface soil and groundwater conditions can vary <br />significantly over small distances, and it is possible that other subsurface conditions <br />and/or contamination may exist in areas that were not investigated. If contamination is <br />discovered, it is likely that the data will not be sufficient for delineating the vertical <br />and/or lateral extent of contamination or to provide an accurate cost estimate for soil <br />and/or groundwater disposal during construction. <br /> No BNSF flaggers or coordination will be required for any of the proposed explorations. <br /> The IDW drums from the geoenvironmental explorations will be stored onsite or at an <br />AGENCY provided location that is within three miles of the site. <br /> Waste profile documentation required for disposal of the IDW will need to be signed by <br />an AGENCY representative. <br /> Estimated HWA labor and subcontractor costs for IDW disposal are for non-hazardous <br />waste IDW disposal. If analytical results indicate hazardous wastes are present, IDW <br />disposal may require disposal as a hazardous waste at a Subtitle C landfill, which may <br />incur additional labor and subcontracting costs. <br /> If contamination is identified in the borings, there is a 50% increase in fees for the HWA <br />material laboratory testing. In an attempt to reduce the cost of the HWA material testing <br />laboratory fees, HWA will wait to select which geotechnical soil samples to analyze until <br />all environmental laboratory analytical results have been received. <br />Deliverables: <br /> Revised Draft Geotechnical Report <br /> Plan Review Comments <br /> Final Geotechnical Report <br />Geotechnical Specification Sections <br />Geoenvironmental Specification Section
