RE: Aggregate Compaction Evaluation
Hinkle Residence
Lot on North Side of 855 Glacier in Cul-de-Sac
Springfield, Oregon
On March 4,2003 a representative from Ford & Associates, Inc. visited the sUbject site to
assess the building pad conditions with respect to the relative compaction of the aggregate
cover,
)3 ~
S -1 d-- '" LI rL
Site testing of the 3/4"-0 crushed aggregate from Springfield Quarry indicates that the thickness
of aggregate is approximately 6-inches over the majority of the pad with up to 2,5-feet along the
north side. The building pad is stepped in the southwest corner and this portion is also covered
with 6-inches of aggregate. In locations where trees and their roots were removed the
aggregate is also thicker. Based on site testing and probing, the aggregate has been
compacted to at least 95% of the matenals maximum dry density of 133.5 pet as determined by
AASHTO T-99 method. The subgrade and aggregate fill are suitable for conventional
residential style perimeter footing construction, We recommend that all footings be reinforced
with at least two #4 steel reinforcing bars, and that surface water be directed away from the
foundatIons and not allowed to pond adjacent to footings, We do not recommend allOWIng
dump-trucks, concrete trucks or other heavy equipment onto the building pad during wet
weather,
Sincerely,
Ford & Associates, Inc.
