The fill consists of 4 to 12-lnches of 11h-inch minus dense graded crushed aggregate from Morse Bros. quarry in Springfield, Oregon. u We inspected the foundation pad excavation, prior placement of the granular fills. Foundation pad excavation was made according to our recommendations and involved stripping and removing 1 to 3-feet of loose organic silts and highly plastic silts from the foundation area. The subgrade was leveled on undisturbed native tan/brown stiff sins over which the granular fills were placed in 12-inch maximum lifts and compacted using a vibratory steel wheeled roller. According to our field.testlng 1 we have determined that the average dry density equals or exceeds an acceptable percentage of the maximum as determined by ASTM 0698. A copy of the field test results is attached to this report. We recommend approval of the foundation fill, as constructed, by the building official. Thank you for the opportunity to be of sBJVice.
