PROCEDURE A total of two (2) soil test holes were drilled at the site. The approximate test hole locations are shown on the appended site plan, Drawing No.l and bear the designation TH-1 and TH-2. Our field work foi this project was performed on August 28, 1984 using a truck -mounted CME-45B drill rig. The test holes were advanced with 3k"i.d. x 7"o.d. continuous flight hollow stem augers which act as a casing to prevent collapse of the sides of the holes Standard penetration tests (split -spoon) were performed in advance of the auger tip at 2 to 5 foot intervals of depth, in accordance with procedures designated in A.S.T.M. D-1586, to obtain an indicst on of -,-.lie density or consistency of the soil and to allow visual exam- ination of representative portions of the soil column. Tt.c borings were drilled to a depth of 20 feet, for a total of 40 lineal feet of drilling. The drilling was performed under th observation of a Subterranean Engineering technician who maintained a continuous log of the soil conditions and obtained soil samples for further classification and testing as necessary. The soils wer examined in the laboratory by a Soil Engineer and classified in accordance with the Unified Soil Classification System, illustrated on the appended chart en'_itled Classification of Soils for Engineer ng Purposes. Detailed soil descriptions along with a plot of the standard penetration test blows per foot are presented on the Borehole Logs, Drawing No.2. Descriptive terminology used on the boring logs is defined in the General Notes also appended to this report. The soil samples will be retained for a period of at least 90 days from the date of issue of this report, after which they will be discarde unless we aLo otherwise notified. All elevations in this report are to geodetic datum, and were obtained using a benchmark supplied by Hickok and Associates (BN1=Lake Minnetonka 929.2 feet- August, 1984). All elevations Are approximate. They should not be used for plan:iing or earthwork oper- ations without confirmation by a Registered Land Surveyor. 1 SUBTERRANEAN ENGINEERING CORP.
