Inspection of Foundation Fill
Project 151.06
At your request, we have inspected the in-place density of granular fills place on the subject foundation pad.
The fill consists of 4 to 12-inches of 11h-inch minus dense graded crushed aggregate from Morse Bras, quany
in Springfield, Oregon.
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 sitts from the foundation area. The subgrade was leveled on undisturbed native
tan/brown stiff siRs over which the granular fills were placed in 12-inch maximum lifts and compacted using a
vibratory steel wheeled roller.
According to Durfield-testing1 we have determined that the average dry density equals or exceeds an acceptable
percentage of the maximum as detennlned by ASTM 0698. A copy of the field test resuns 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 service. Please call us it you have questions or need further assistance.
Respectfully,
