RE: Aggregate Compaction Evaluation Beecher Residence lot on Horth Side of 855 Glacier in Cul-de-Sac Springfield, Oregon On December 23, 2002 a representative from F-ord-Ness-Fassbender. Inc. visited the subject site to assess the building pad conditions with respect to the relative compaction of the aggregate cover Site testing of the 1"-0 crushed aggregate from Springfield Quarry indIcates that the thickness of aggregate is approximately,4- to 8-inches oller the majority of the pad. In locations where trees and their roots had been removed the aggregate is up to several feet thick. Based on site testing and probing, the aggregate has been compacted to at least 95% of the materials II U2Kimum 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 remfQrced with at least two #4 steel relnforcmg bars, and that surface water be dlreeted 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-Ness-Fassbender Inc. 11 II Hwy ~~ N I Suite 1 00 JI POBox n71~.
