GeoEngineers has provided on -call geotechnical monitoring and testing services during
construction of the Tigard Triangle Project This letter summarizes our observations and testing
for the building foundation and associated site work. GeoEngineers prepared a geotechnical
engineering report for this site titled "Report of Geotechnical Engineering Services, Proposed
Tigard Triangle Development, Tigard, Oregon," dated May 8, 1998.
A GeoEngineers representative observed stripping, subgrade preparation, and excavation for
the building between May 21, 1999 and June 14, 2000. Based on our observations, the native
soils containing vegetation and roots were stripped and the building and parking area subgrades
north of Southwest Elmhurst Street were prepared in accordance with the project specifications
and the recommendations in our geotechnical report.
A GeoEngineers representative observed placement and compaction of structural fill to raise
site grades in the area of building "A " on the north side of the site. A GeoEngineers
representative observed material types aid conducted 'nuclear density testing and/or observed
proofroll of in -place material. GeoEn I gineers reviewed settlement data provided by Baugh
Construction for the fill placed in the *ding area. Based on our observations, the fill was
placed and compacted in accordance with project specifications and the recommendations in our
geotechnical report.

A GeoEngineers representative perfotjmed in -place nuclear density tests on crushed rock base
placed beneath the floor sIab, and in utility trenches. Areas where the test results indicated
inadequate relative compaction were reworked and recompacted. Based on ow testing and
observations, the subgrade and base rocklin the building pads were prepared in accordance with
project plans and specifications and the endations in our geotechnical report.
