<br />Reporting Period August 12, 1997 -August 17, 1997. <br />Current Schedule <br />A gantt chart of the schedule and progress of genera] construction activities for the project is <br />attached. Other specific tasks of interest are as follows: <br />Main Crossing (Wall F-1 and F-2) In Progress Complete 9/12 <br />Cut Slopes above Shaft #1 and #2 Complete <br />Pond SG-1 and Main Drainage In Progress Complete 9/15 <br />Landing #2 Road Complete <br />Water Tank Extension Indefinite Hold <br />Lower Sylvester Gulch Road Begin 8/27 Complete 9/20 <br />Field Monitoring and Observations <br />2 <br />A complete field inspection was conducted Friday, August 15, 1997, and Sunday, August 17, <br />1997, to visually observe and evaluate the stability of slopes within the project area. Data <br />collection efforts and evaluation or re-evaluation of specific areas of concern continues. <br />Individual areas are discussed in detail in the following sections. Supporting documentation is <br />attached for your review. <br />RPE: No movement, slumping, or cracking has been observed on any finished or in-progress <br />slope at the RPE since the beginning of the project in late May. <br />Lower Svlvester Gulch Road: Observation of the cut slopes and other disturbed slopes <br />adjacent to widened sections of the Lower Sylvester Gulch Road showed no failures or <br />slumping on August 15. A fourth reading at inclinometer I-2 was taken, and movement <br />remains slower than anticipated. Monitoring and evaluation of I-2 will continue. Golder <br />Associates is completing re-analysis of the slopes at and around inclinometer I-4 and has <br />begun redesign of the lower road from Station 20 through Station 34. Preliminary redesign of <br />this section includes flatter slopes (2:1 vs. I.5:1) and a shift in alignment further away from <br />the creek, which will eliminate MSE Walls B and C. <br />Upper Svlvester Gulch Road: No failures, movement, or new cracking were observed at the <br />failed fill area (Stations #62 to #68) on August 15 or August 17. All other pioneered sections <br />of the main road appeared stable, including both approaches to the main crossing (F-walls). <br />Monitoring of inclinometer I-12 at the failed fill area continues to show small movements at <br />approximately 6' to 10' below ground surface (BGS). Surface surveys continue to indicate no <br />appreciable movement either above the cut slope or below the fill area. Representatives from <br />Golder Associates and Barr Engineering were on site on August 13 to inspect the area and <br />observe the opening of Shelby tubes taken during I-11 and I-12 installation. Test pits have <br />been postponed pending discussions with CDMG on the need for a minor revision for this <br />work. The Shelby tubes were logged by both Golder and Barr, and some were repackaged <br />for further laboratory analysis. Notable observations include the Shelby tube sample from 6'- <br />
