The findings of our observations and recommendations for the foundation design are presented in this report. The services were performed in accordance with our agreement for professional engineering services to you dated October 29, 2012. The deck will be attached to the south side of residence and replace an existing deck. It is planned to found the deck on isolated footing pads. We assume relatively light foundation loadings for the deck. The residence has a garden level basement (about 5 to 6 feet deep) and assumed foundation backfill in the area of the proposed deck. At the time of our site visit, one pit (Pit 1) had been dug to a depth of about 3%z feet in the area of the deck addition. The pit was located about 6 feet south of the middle of the south side of the residence. The soils exposed in the pit, below about 2 feet of man- placed fill, consisted of relatively dense, silty to slightly silty sandy gravel with cobbles that extended down to the pit depth of 3'% feet. The results of a gradation analysis performed on a sample of natural coarse granular soils (minus 3 inch fraction) obtained from the pit are presented on Figure 1. No free water was encountered in the pit and the soils were slightly moist. Considering the conditions exposed in the pit and the nature of the proposed construction, spread footing pads placed on the undisturbed natural coarse granular soils designed for an allowable bearing pressure of 2,500 psf can be used for support of the deck addition. There could be some differential settlement with respect to the existing structure which should be considered in the design. Footings should be a minimum width of 2 feet for the footing pads. All fill, topsoil and loose disturbed soils in the footing areas should be removed and the bearing level extended down to the undisturbed coarse granular natural soils. This could require subexcavation below design bearing elevation in some areas. Jack Carnie October 31, 2012 Page 2 The bearing soils should be protected against frost and concrete should not be placed on frozen soils. The footings should be provided with adequate soil cover above their bearing elevations for frost protection. Backfill of the footing pads can consist of the on- site soils, excluding topsoil and oversized rocks, compacted to at least 90%of standard Proctor density at a moisture content near optimum(95% in slab areas). The Backfill should have the surface graded to prevent ponding within at least 10 feet of the building and footing areas. The recommendations submitted in this letter are based on our observation of the soils exposed within the pit excavation at the location and to the depth indicated, and do not include subsurface exploration within the loaded depth of foundation influence. This study is based on the assumption that soils beneath the depth explored have equal or better support than those exposed. In order to reveal the nature and extent of variations in the subsurface conditions below the excavation, drilling would be required. It is possible the data obtained by subsurface exploration could change the recommendations contained in this letter. We should observe the footing pads excavations at the time of construction. If you have any questions or need further assistance, please call our office. Sincerely, HEPWORTH-.P._WLAK GEOTECHNICAL, INC. David A.
