86-200 <br />Honeywell, Inc. -3- May 14, 1986 <br />understood that very limited information regarding the current <br />ground water conditions is obtained based on shallow hand auger <br />probings. Seasonal fluctuations in ground water levels should be <br />anticipated. <br />Based on the results of our observations and hand auger probes, <br />no fill appears to have been placed at the site. The clays <br />encountered at the site are believed to be of natural glacial <br />till origin. <br />RECOMMENDATIONS <br />Prior to construction, all vegetation and topsoil should be <br />removed from the proposed building and paved areas. We antici- <br />pate this will require excavation of approximately 1 to 2 feet. <br />We anticipate grade changes at the site to be relatively minor. <br />The existing grades are conducive to good surface water drainage. <br />We recommend that any future grade changes provide for adequate <br />surface water drainage away from the proposed house location. <br />The mottled coloration and rust staining of the soils at the site <br />indicates the possibility that ground water exists within eleva- <br />tions proposed for the basement area. To minimize the potential <br />for a wet basement, the basement walls should be waterproofed and <br />a drain tile system be provided around the perimeter of the <br />basement. <br />We anticipate that all footings and floor slabs will be founded <br />on natural soils. However, should fill be required below the <br />foundation or floor slab, we anticipate that the on -site clay <br />materials may be too wet to reuse as fill unless dried. If <br />dried, the clay may be placed and compacted for floor slab or <br />foundation support. Compaction tests should be taken to help <br />evaluate if adequate densities have been obtained for support of <br />the anticipated foundation loads. <br />Once the footing areas have been excavated and prior to placement <br />of any fill, we recommend that the soils encountered at the pro- <br />posed footing grade elevation be observed by a Soils Engineer or <br />his representative to help evaluate if the natural soils are <br />suitable for foundation support. <br />Based on the results of our observations and hand auger probes, <br />it is our opinion that the natural soils encountered at the hand <br />auger probe locations are suitable for support of the anticipated <br />floor slab and light foundation loads. However, the hand auger <br />probes were likely not taken at the same elevation or location of <br />
