Garfield County Engineering 0375 County Road 352, Building 2060 Rifle, Colorado 81650 Attn: Mr. Withee, As requested, a representative of GROUND visited the project to perform construction observations and materials testing. We observed moisture contents well above optimum in the top 6" to 12" of material as well as standing water in multiple areas. We utilized a shovel to remove the top 6" of oversaturated material in the traffic area and observed approximately 18" of frost beneath the mud. In the landscape area (free of traffic) we observed 9" to 11" of frost with 4" of mud on top of the frost. Three samples were obtained at 30' north and 30' west of gridlines A.0/1.0, 25' north of gridlines C.0/2.0, 65' north and 50' west of A.0/1.0. After laboratory analysis, it was determined that the moisture contents were as follows: ♦ 30' N, 30' W of Gridlines A.0/1.0 ♦ 25' N, 0' W of Gridlines C.0/2.0 ♦ 65' N, 50' W of Gridlines A.0/1.0 18.4% 20.1% 16.1% Based on these test results and the typical optimum moisture contents for on-site soils analyzed, it appears that upon thawing of the subgrade materials, approximately the top 12-18" of material will likely be above recommended moisture contents for acceptable performance for subgrade materials.

The concrete was supplied by United/35510705, approximately 1 cubic yard. This concrete was excess from Garfield Human Services. It was placed at the Sherriff's Annex at approximately 11:15 AM.
