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 materials testing and construction observations. We observed construction of CMU walls at gridlines G.0/1.0-6.0. Berich Masonry was constructing walls at 0' to 8' high with cleanouts. We observed the reinforcing steel for specified bar sizing, spacing tolerances, lap splices and cell clearances. We also observed the placement of the block, bond beams, lintels, ladder placement, mortar, grout and the overall condition of the wall. The CMU walls and the reinforcing steel appeared to be constructed in general accordance with the project plans and site specifications. We also assisted Kevin McClure in obtaining concrete cores from an existing slab on grade Jim with Neenan was informed of all of our observations. Sincerely, GROUND Engineering Consultants, Inc.

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. Terry with CMC was notified of our on-site observations. Sincerely, GROUND Engineering Consultants, Inc. Michael Konopka / Michael K. Wariner, P.E.

We observed Advanced Concrete place concrete under and around the base of the steel support posts at gridlines B.0/3.0. Based on our observations it appeared the concrete was placed in a manner that forced the concrete underneath the support post plate. This was unable to be verified though. 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. Cylinders were cast at Garfield Human Services as well as slump, air and unit weight. Terry with CMC was notified of today's observations. Sincerely, GROUND Engineering Consultants, Inc.
