Box 1121 • Hayden, CO 81639 • (970) 276-2087 June 2, 2017 Savant Homes, Inc. 4100 Main Street Timnath, Colorado 80547 Attn: Mr. Caleb Bussard Re: Construction Materials Testing and Observation Services Summary Report Mountain & Shields Fort Collins, Colorado Soilogic Project # 17-2017 Mr Bussard: During the period of February 28 through May 12, 2017, Soilogic Inc. (Soilogic) provided construction materials testing and observation services for the referenced project. Our services were provided on a part-time basis and included the observation and testing of reconditioned subgrade and concrete delivered to the site for placement. Results of the observation and testing services completed during the referenced period are included with this report. During the referenced period, Soilogic personnel obtained two (2) representative samples of the onsite site soils for laboratory evaluation of the moisture density relationship of those materials. The laboratory testing completed on the obtained samples included a standard Proctor (ASTM D-698) test. Results of the completed standard Proctor tests were used to evaluate the percent compaction and moisture variability with reworked soils in the field and are included with this report. During the referenced period, Soilogic personnel performed field moisture/density tests on reconditioned subgrade materials that had been placed and compacted prior to and during our site visits. The field moisture/density tests were completed at random locations within the subgrade areas and were performed in general accordance with ASTM Specification D-2922. Results of the field moisture/density tests completed during the referenced period are included with this report. The field moisture/density test results met the project compaction requirement of at least 95% of the material’s standard Proctor maximum dry density and ±2% of the materials optimum moisture content. Construction Materials Testing and Observation Services Report Mountain & Shields Fort Collins, Colorado Soilogic # 17-2017 2 During the referenced period, Soilogic personnel observed and tested cast-in-place concrete delivered to the site for construction of sidewalks and curb and gutter. The testing completed in the field included slump, air content, unit weight, concrete temperature, and ambient air temperature at the time of placement. Test cylinders were molded from representative samples of the plastic concrete for laboratory curing and compressive strength testing. Results of the field and laboratory tests performed during the referenced period are included with this report. Results of laboratory concrete compressive strength tests completed during the referenced period are also included and will be provided as they become available. We appreciate the opportunity to be of service to you on this project.
