Great West Steel Industries, Inc. <br />Attention Russell T. Kenney Page Two <br />It is our understanding that the mill building will impose loads <br />on approximately 40 columns with individual column loads on the order of <br />SO kips each. It is our recommendation that these columns be supported <br />on shallow spread footings designed for an allowable soil bearing pressure <br />of 4000 lbs. psf. Since the upper 6 to 12" of the clay stratum has been <br />moderately softened due to the influence of moisture and weather conditions <br />we recommend that the footings bear at a depth of 3 feet below the existing <br />site grade. Since construction will commence during the wetter season, the <br />contractor is cautioned to protect footing excavations from accumulation of <br />water which will soften the bearing surface. All footing excavations are to <br />be inspected by the soils engineer just prior to placing the concrete. <br />Settlement of footings founded in this manner will be nominal. <br />The site area has been used for storage of steel plate for some <br />years. This is considered adequate preparation for floor slab support and <br />no further treatment should be necessary. The floor slab may be placed <br />directly on the site surface after fine grading as necessary. If a footing <br />should fall in the vicinity of Test Pit 1, it should not be placed until the <br />soft backfill in this test pit is replaced with compacted granular fill. <br />If you have any further questions, please do not hesitate to <br />call on us. <br />0 <br />PRW:mm <br />Attachments <br />3 copies submitted <br />A, - <br />Respectfully submitted <br />J�"�Co� <br />By Paul R.
