<br /> IkTRODUCTIQN
<br /> This letter presents a summary of our gcoicchnical construction observation serviccs for Building Nos. 10
<br /> and 12 through 15 of The Millington at Merrill Crcek located in Everett, Washington. We have provided
<br /> geotechnical construction observation serviccs for the entire project but only the construction
<br /> observations completcd for Duilding Nos. 10 and 12 through 15 located within Pod 2 are presented in this
<br /> lener. We previously provided four summary Icners,the first dated luly 12,2006 for Ruilding Nos.2 and
<br /> 19, the second da�ed July 21, 2006 for buildings 3 and 4, thc third dated August 30, 2006 for Building
<br /> Nos. l, 5 and 6 and the fourth dated October 26, 2006 for Building Nos 7, 8, 9 and I l. We will provide
<br /> separate letters that will summarize our construction observations completed for the other buildings and
<br /> areas of the project.
<br /> The gcotec{micul aspects associated with construction of Duilding Nos. 10 and 12 through IS included
<br /> soil bearing verification and structural fill material characteristics,placement and compaction verification.
<br /> SUMMARY
<br /> Bazed on our observations, it is our opinion that the construction activities at Building Nos. 10, 12
<br /> through 15 observed by GeoEngineers were complcted in general accordance with our recommendations,
<br /> and the project plans and specifications.
<br /> OBSERVATIONS
<br /> We visited the site on a full time basis on 7 occasions between July 19, and July 28, 2005 (refer to field
<br /> report Nos. 24 through 31) during thc mass grading period and completed I site visit on August 3, 2006
<br /> (refer to field report No. 35) to evaluate compaction of the fill placed within the Pod 2 area where
<br /> E3uilding No. 10 and 15 are located. Duilding Nos. 12 through 14 are located in a cut area within Pod 2.
<br /> We completed intennittent site visits on 12 occasions between Seprember 6, 2005 and May 10, 2006
<br /> (refcr to field report Nos. 57, 58, G7, 76, 112, 114, 115, 125, 126, 136, 139 and 140) to evaluate the
<br /> footing subgrade soils within Building Nos. 10 and 12 through I5. Backfill placed to support the upper
<br /> tier of building slab was evaluated on 13 occasions behveen November 18,2005 and April 27, 2006(refer
<br /> ro 6eld report Nos. 93 through 97, 101, 102, 127, 129, 130, 132, 133, and 137). A complete set of field
