Town Engineer Report#: 65 Sheet: 1 of 1 Department of Public Works/Transportation 1309 Elkhorn Drive Vail,Colorado 81657 Project: Lionshead Transit Center,Vail, Colorado Weather: � Sunny ❑ Cloudy ❑ Rain ❑ Snow Temp: 46°F± Construction Activities/Observations: Field engineer arrived on site, as requested, to perform moisture and density testing below the western-most retaining wall. The area was excavated to grade from Gridline E-E.0 to Gridline �D.O but had not been compacted. The soils exposed in the lowest area were not wet and just needed to be compacted. However, at the first step up and on, the soils in this area were wet and very soft between Gridlines�D.O and�D.S. The contractor proposes to remove approximately 2 feet of the material, place geogrid, and then bacicfill with suitable material. No moisture and density testing was performed during this site visit.
