Phase IV Weekly Summary No. 35 Page 3 003-2203 <br />Field Monitoring and Testing Activities <br />• Golder observed construction activities associated with Phase IV earthworks. All construction <br />materials and soil materials were verified as suitable and construction methods were in accordance <br />with project specifications. Removal of oversized and deleterious material from all fill areas was <br />observed. <br />Golder observed the Phase Na secondary underdrain construction for correct dimensioning as per <br />specifications of four foot in width and two foot in depth to accommodate materials. Twelve-ounce <br />geotxtile, was installed before (3 weeks ago) the installation of 12-inch minus underdrain fill. The <br />geotextile was then wrapped over the anderdrain fill as six inches of three-inch maximum-sized SSF <br />material was installed over the geotextile. The remaining construction of the underdrain measured <br />approximately 150 feet in length, commencing at Highway 67 and following the natural topography <br />to the tie in with the existing underdrain previously constructed. The tie-in between the proposed <br />primary underdrain and the aforementioned secondary underdrain will be constructed at a later date. <br />Laboratory Test Results <br />One sample of Structural Fill (SFa-07) was collected and transported to the Golder field trailer for <br />index testing analysis. Test results for Sfa-07 met project specifications and is reported in <br />Attachment C. <br />Meetines <br />CC&V held a Weekly Contractor meeting on October 2"d.
