We performed a geotechnical investigation of the site, the results of which were presented in our report of Geotechnical Engineering Services dated December 10, 2002, and performed geotechnical observation during construction. Our observations were completed on an on-call, part-lime basis between the dates of November 19, 2002 and July 17, 2003. This letter conoems observations and testing performed on Lots 1-6 since the final summary letter dated November 19, 2003 was sent out • Site Stripping: Prior to construction, the site contained surface vegetation in structural areas. Roadways and lots were stripped of vegetation between November 19 and 2e. 2002. Based on our field observations, the site was stripped of organic topsoil in general accordance with our recommendations. • Subgrade Conditions: After stripping had been completed, the site subgrade soil was cement treated for planned construction activities in the winter. Based on our field observations, the subgrade soli has been prepared in general accordance with our recommendations. • Roadway Fill Placement and Compaction: Up to 2 feet of fill was placed and compacted on roadways in the southeast corner of the site. CGT conducted 6 in- p lace relative compaction tests on the native brown sift fill. Based on our field observations and in place density testing the native silt fill for roadways was placed and compacted in general accordance with our recommendations (92 percent of ASTM D- 1557). • Roadway Aggregate Base Rock: CGT conducted 12 in -place relative compaction tests on the roadway aggregate base ruck on May Z 2003_ The roadway 11 :1/05 TUE 13:12 FAX 503 670 9147 t;ArtLbuly 1t,11t'; - _ Hawks Beard Townhomes Tigard, Oregon June 14. 2004 aggregate base rock was prepared in general accordance with the recommendations given by the City of Tigard (95 percent of AASHTO T -99). • Roadway Pavements: Asphalt was placed on the South Alley, North Alley, Hazelwood, Briarwood, Woodridge, Huntington, and Hawks Beard on May 13, 2003. CGT conducted 17 in -place relative compaction tests on the asphalt. Test results ranged from 91 to 93.1 percent of ASTM D - 2950. • Lots: Based on our field observations, lots 8 through 13, and lots 1 through 3 were cut and are on native silt. The remaining 53 lots are on structural fill up to 3 feet deep. Based on our observations and in-place relative compaction testing. lots 1 through 62 have been prepared in general accordance with our recommendations. • Foundation Bearing Surfaces: Foundation bearing surfaces were not prepared at the time of this report; therefore, we have not observed any of the foundation subgrade soils for the proposed residences- ... ;i . -- - -- - ..... - . - - pouiing— eonerete. We understand that the City of Tigard will not require individual lot foundation subgrade observations. • Utility trench backfill compaction. CGT conducted 28 in -place relative compaction tests on utility trench backfill material for the sanitary sewer and storm sewer trenches. Based on our density testing, the utility trenches backfill has been compacted in general accordance with the recommendations given by City of Tigard (95 percent of AASHTO T -99). Based on our observations, as documented in our field reports, and to the best or our knowledge, within our scope of work, the above geotechnical summaries accurately reflect our observations. Our services were provided on an on -call basis, in which we relied on the contractor to contact our office for the scheduling of our services. We cannot be held contractually responsible for those items, if any. that we did not observe or test.
