October 23, 2013 Rubin Construction 96 Lone Pinon Lane Silt, CO 81652 Attention: Mr. Thomas Rubin Subject: Excavation Observation Lot 3, Ries Exemption Plat Garfield County, Colorado Project No. GS05652-305 As requested, we visited the subject site on October 9, 21 and 22, 2013. The purpose of our site visits were to observe the soils exposed at footing elevations. CTL 1 Thompson, Inc. performed a soils and foundation investigation for the subject site (CTL 1 Thompson, Inc. Project No. GS04960-120, dated May 17, 2007). Based on our observations removal of sandy clay with organics to expose natural gravels was performed subsequent to our October 9, 2013 observation. We recommended raising the bottom of footing elevation due to the presence of ground water during our October 21, 2013 site visit. The building excavation was appropriate for footing installation at the time of our October 22, 2013 site visit. The soils exposed at the bottom of the foundation excavation consist of natural sandy clay over gravel with cobbles and similar structural fill soils at footing levels. We appreciate the opportunity to work with you on this project. If you have questions or we can be of further service, please call.
