1111- •• Ms. Mary Saarion January 27, 1995 Page 2 We have visited the site and, assuming we do not receive a significant snowfall, we able to gain access to representative test locations with a 4-wheel drive, one-ton truck drill rig Scope of Services Fieldwork To evaluate the athletic field area, we propose to drill and sample three standard penetration test borings (ASTM:D 1586). Our proposal is based on a total boring lineal footage of 48 feet for these 3 borings, resulting in an average depth of 16'. The program may be altered depending on conditions encountered, although will plan to limit ourselves to 48 lineal feet to remain within budget. To aid your evaluation of the parking lot improvements, we propose to place two flight auger • borings (ASTM:D 1452) to a depth of 4W each. Our services will include arranging clearance of underground public utilities through the Gopher State One Call System. We will also document the boring locations and measure the surface elevation at each test location. Laboratory Our services will include mechanical laboratory testing of selected soil samples to aid in judging engineering properties of the soils. In this proposal, we have budgeted for S75 for geotechnical laboratory testing. If conditions are encountered which indicate the laboratory program should be expanded for proper evaluation, we will review the recommended tests and associated cost with you prior to proceeding. Engineering Report • Following the field and laboratory work, a formal engineering report will be prepared and submitted. This report will include logs of the test borings, the laboratory test results, a review of engineering properties of the on-site soils, and our geotechnical engineering opinions and recommendations regarding the following: • Estimates of future settlements or heaves of the athletic field area • Grading procedures to correct the athletic field area if the future movements are • anticipated to be excessive. • Parking lot subgrade preparation (if needed) • Estimated subgrade R-value
