<br /> INTRODUCTION
<br /> This letter presents a summary of our geotechnical construction obscrvation services for Building Nos. 10
<br /> and 12 through 15 of The Millingron at Merrill Creek located in Everett, Washington. Wc have provided
<br /> geotechnical construction observation services for the entire project but only the construction
<br /> observations completed for[3uilding Nos. 10 and 12 through I S located within Pod 2 are presented in this

<br /> areas ofthe project.
<br /> The gcotechnical aspects usociated with construction of Building Nos. 10 and 12 through 15 included
<br /> soil bearing verification and swctural fill material characteristics, placement and compaction verification.
<br /> SUMMARY
<br /> Based on our observations, it is our opinion that the construction activities at Building Nos. 10, 12
<br /> through I S observcd by GeoF,ngineers were completed in general accordance with our recommendations,

<br /> OBSERVATIONS
<br /> We visited the site on a full time basis on 7 occasions between July i9, and July 28, 2005 (rcfer to field
<br /> raport Nos. 24 through 31) during the mass grading period and completed 1 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 wherc
<br /> E3uilding No. 10 and 15 are located. Duilding Nos. 12 throu,gh 14 arc located in a cut area within Pod 2.
<br /> We completed intermittent site visits on 12 occasions between September 6, 2005 and �fay 10, 2006
