We visited the site on August 20, 1997 to observe site conditions. Our scope of services included visiting the site to observe the soil conditions and preparation of this letter. The site is currently a gravel pit. The building area has been mined for sand and gravel to approximately seven feet below grade. Large piles of glacial till strippings were observed in the central portion of the proposed building. We understand the piies of glacial till strippings wiil be used as structural fill for the lower areas. The subgrade where fill will be ptaced was evaluated by observing loaded scraper traffic. The subgrade is de�se glacial till and is adequate for fill placement. Based an our observations, it is our opinion the project can be constructed generally as planned. Buiiding support may be provided using conventional spread and continuous foundation systems bearing on the dense to very dense native soils or on structural fill used to modify site grades. Slab-on-grade floors may be similarly supported. Foundations For frost protection considerations, exterior foundation elements should be placed at a minimum depth of eighteen (18) inches below final exterior grade. Interior spread foundations can be placed at a minimum depth of twelve (12) inches below the top of slab, except in unheated areas, where interior foundation elements shouid be founded at a minimum depth of eighteen (18) inches. 1805 -136ih Place N.E., Suite 201, Bellewe, Washington 98005 Believue (?O6) 645�3780 Seanle (206) 464�1584 FAX (206) 74-608-60 Tacoma (20fi) 272�6606
