2/10/2014 State.co.us Executive Branch Mail - FW: WeeldyCQA Report Questions statement indicating average soil temp was above 32 degrees was no longer in the report. This brings questions related to the spec, specifically Section 02200.0, Part 3.06, ¶ A.2 - no frozen material shall be incorporated into fill. The fill Materials are monitored for temperature throughout the placement. No frozen fill is placed. This general statement was removed as when we state that the fill material was placed per method specification that includes the quoted specification. 2) Week ending 10/26/13. There was an extra 313 ft of secondary underdrain placed due to wetter than expected conditions. This will need to be included in the as- builts. This information will be asbuilt. 3) Weeks ending 12/21/13 & 1/4/14 - mention was made of placing "rock fill ". There is no spec for rock fill or its placement. This is a field slang due to the large rock used as Structural fill. I corrected the reports to read Structural fill and they are attached. 4) Weeks ending 12/21/13 & 1/11/14 - mention was made of excavating 1/2:1 slopes. I'm just looking for some additional explanation on this. The slope above the proposed ADR -2 platform is designed at a .5 to 1. 5) Clay borrow soil samples: Sample #79 -S was taken the week ending 12/21/13. Apparently no samples were taken over the next 2 weeks due to the holiday work suspension. The first clay sample for the week ending 1/11/14 was #81 -S. Was a #80 -S sample taken, and when? Sample # 80 was taken on 1 -4 -14. 6) 1 cannot find a report for the week ending 11/30/13. Attached. thought you might need to do some research into some of these, thus the reason for the heads up email, instead of a phone call. Please call me this week when you've gotten familiar with theses items, so we can discuss them. Thanks. Tim Cazier, P.E.
