Our work was performed in accordance with the authorization of Josh VandenBos with the City of Sioux Falls - Engineering Department. The scope of work as presented in this report is limited to the following: 1. To perform 41 test borings to gather data on the subsurface conditions at the site (test borings are labeled 1 through 27 and 50 through 63). However, we were unable to perform 4 of the test borings (test borings 1, 6, 7 and 8) due to conflicts with existing utilities. Also, we did not perform test boring 62 because it was located within 5 feet of test boring 19. Therefore, only 36 test borings were performed. 2. To perform laboratory tests that include moisture content, dry density, sieve analysis (#200 sieve wash), Atterberg limits (liquid and plastic limits), standard Proctor, swell, unconfined compressive strength, consolidation, resistivity, pH, redox potential, sulfide content, chloride content and sulfate content. 3. To install 11 temporary groundwater observation wells to gather groundwater data on a periodic basis at the site. 4. To prepare an engineering report that includes the results of the field and laboratory tests as well as our earthwork and foundation recommendations for design and construction.
