Phase IVb Weekly Summary No. 17 Page 3 003-2203 <br />• mazked and removed. Destructive fusion and extrusion seam peel and shear tests of these samples were <br />not performed during this reporting period. <br />Phase IVc <br />Ames continued limited cut to temporary stockpiling activities within the limits of the Phase Nc azea. <br />Field Monitorine and Testine Activities <br />Golder observed construction activities associated with Phase IV earthworks. All construction <br />materials and soil materials placed were verified as suitable, and construction methods were in <br />accordance with project specifcations. Removal of oversized or deleterious material from all fill <br />azeas was observed. Golder observed SF placement in Phase IV for materials, lift thickness, <br />moisture content, and compactive effort. <br />Golder observed re-compaction of LVSCF in the Phase IVb PSSA sump after rainfall flooded the <br />area. The HVSCS riser foundations were compacted and re-graded. Golder CQA monitors <br />performed four nuclear moisture-density tests (LVSCNb-Ola through LVSCNb-04a) on LVSCF re- <br />compacted within the Phase IVb PSSA sump. The tests performed met the requirements of the <br />specifications and the nuclear moisture-density results summary is presented in Attachment B. <br />Golder visually observed the placement and grading of LVSCF in the Phase IVb PSSA azea. Golder <br />• CQA monitors (one monitor per dozer when dozers are greater than 50 ft apart) observed LVSCF <br />placement and verified minimum thickness of 3 feet. <br />Golder visually observed the placement of DCF in the Phase IVb PSSA area. Golder CQA monitors <br />(one monitor per dozer when dozers are greater than 50 ft apart) observed DCF placement and <br />verified minimum thickness of 2 feet. <br />Golder observed anchor trench excavation in the Phase IVb PSSA and OSA for proper location and <br />dimension (2' wide by 3' deep). Anchor trench excavation met or exceeded the requirements of the <br />specifications. Golder observed anchor trench backfill in the Phase IVb PSSA for lift thickness and <br />compaction. <br />Golder observed construction of the Primary Underdrain in Phase IVb for trench dimension (5' wide <br />by 3' deep), slope (minimum 1%), materials, and geotextile overlap. Primary- Underdrain <br />construction met or exceeded the requirements of the specifications. <br />Golder observed and monitored placement of Bedding Fill (BF) in the Phase IVb PSSA for proper <br />location and thickness (I' deep). Golder monitored compactive effort and finish grading to verify <br />conditions met specification. <br />Golder observed geomembrane deployment, documenting ambient air temperature, panel <br />dimensions, thickness, seaming, tie-in overlap, and seam testing (trial seams, pressure, vacuum, and <br />• destructive). Geomembrane placed in the Phase IVb azea met the project specifications. <br />Phase lVb it MaylYMayi], 2401 GOId¢r AssOCiateS lnC. <br />
