645 -3601 TWIN CITY TESTING AND ENGINEERING LABORATORY, INC. REPORT OF: LABORATORY No. 9 -4910 ENGINEERS AND CHEMISTS 662 Cromwell Avenue - St. Paul, Minn. 55114 EXCAVATION INSPECTION DATE: September 5, 1972 PAGE: 3 CONCLUSIONS Based on the results of our inspection it is our opinion the natural underlying soil net- work in the areas inspected will offer adequate support for the necessary fill material and designed unit loadings with no resulting detrimental settlement. With respect to the fill material, our field density tests indicate the fill in the areas tested was sufficiently compact to receive the designed unit loadings. In addition, the results of the deep penetration boring indicate a soil profile consisting of relatively dense fill underlain by competent strata of natural cohesive soils. The relatively loose layer of fill encountered in the fill stratum would be of insufficient thickness to cause structural problems, provided this information is representative of thickness conditions at the site. REMARKS Our inspections at the project indicate the excavation procedures are being properly executed. Assuming the entire excavation was carried down to the competent silty clay or granular soils id the compaction tests and standard penetration borings are representative of the entire Bite, we would not anticipate settlement or consolidation in the soil system of amagnitude detrimental to the structure.
