Reference Technical Specifications: Earthworks Section 02200, 3.06 fill Placement, <br />A. General Guidelines, and Paragraph 10. Soil temperatures were measured Friday morning (8-readings, <br />throughout the fill) high of 50° F to a low of 38° F, average mean temperature of 41° F. In addition, <br />referenced that all snow must be removed prior to placing fill, and, all "smooth" surfaces must be scarified <br />a minimum of 2-inches prior to subsequent lifts. <br />Other Items discussed were to forward on a weekly basis to CC&V a spread sheet to include all laboratory <br />test results as they are completed and to increase the permeability testing to 4-samples per week (in <br />progress). Additionally, a daily report shows a man-hour budget including daily hours, % man-hour <br />budget complete, VS man-hour budget and man-hours remaining. This is designed to be a tracking tool for <br />AMEC and CC&V, (now in progress). <br />Sheet 4 of 8 VLF Weekly Report WE 03.14.09.D
