This letter provides GeoDesign, Ines summary comments on the geotechnical construction
observation services completed for Building 2 at the Tigard Triangle Commons project in Tigard,
Oregon. We previously performed a geotechnical evaluation of the site. Our study was
performed in two phases, with the results provided in our September 28, 2001' and July 19.
2005 reports.
GeoDesign observed the mass grading operations, which induded site cuts and fills. We
observed all foundation and floor slab subgrades prior to Concrete placement Crushed rock
material for concrete floor slab support and utility trends and retaining wall badcfill were
evaluated by completing in -place density testing_
Members of our geotechnical staff observed geotechnical- related tasks identified above on a part -
time and on-call basis. The results of our site visits were summarized in daily field reports, which
have been provided to the design /construction team members. Areas where test results
indicated inadequate relative compaction were reworked and re- compacted until the specified
compaction was achieved. Within the limits of work observed and reported during the requested
site visits, the above - referenced tasks were completed in general accordance with the plans and
spedfications and the geotechnical recommendations.
