City of Elk River <br />AET Proposal No. 26-00324 <br />March 13, 2009 <br />Page 2 of 4 <br />Dimension and document boring locations based on existing surface features and/or <br />staked property corners. <br />Obtain ground surface elevations at each boring location using a nearby permanent <br />benchmark. <br />Based on our observations of the site, it is our opinion that a conventional truck-mounted drill rig <br />can access the site and perform the soil borings. In the event snow removal is required for our <br />truck-mounted drill rig to access the boring locations we understand the City will complete this <br />snow removal. <br />Soil Laboratory Testing <br />Our services will include mechanical laboratory testing of selected soil samples to aid in judging <br />engineering properties of the soils. In this proposal, we have budgeted $300 for geotechnical <br />laboratory testing. If conditions are encountered which indicate the laboratory program should be <br />expanded for proper evaluation, we will review the recommended tests and associated costs with <br />you prior to proceeding. <br />Engineering Report <br />Following the field and laboratory work, a formal engineering report will be prepared and <br />submitted. This report will include logs of the test borings, the laboratory test results, a review of <br />engineering properties of the soils found at our boring locations, and our geotechnical <br />engineering opinions and recommendations regarding the following: <br />• Grading procedures to prepare the building area for structural support. <br />Foundation types and depths. <br />• An allowable soil bearing capacity for design of spread footings. <br />Estimates of foundation settlement. <br />• Support of the floor slab of the building, including comments about the need for a <br />moisture-vapor membrane. <br />• Comments on the suitability of the on-site soils for reuse as fill. <br />• Soil parameters for design of below-grade foundation walls, including lateral loads and <br />the need for draintiles. <br />• Comments on other items which may affect final performance or constructability, such as <br />frost heave and drainage considerations. <br />The scope of work defined in this proposal is intended for geotechnical purposes only. This <br />scope is not intended to explore for the presence or extent of environmental contamination at the <br />site. However, we will note obvious contamination encountered which can be detected by <br />human sight or smell. <br />
