Geofingineera prepared a geotechaical engineering report for this site titled "Report of Geoteclmical 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, 1999. The subgrade was proofiolled using heavy construction equipment Based on our observations, the native soils containing vegetation and roots were stripped and the building and paxidng area subgrades were prepared in accordance with the project specifications and the recommendations in ow geotechnieal report. A GeoFngineers representative observed placement and compaction of struetural fill to raise site grades. Placed and compacted fill was 1 to 2 feet thick in the southeast portion of the site and up to 18 feet in the northwest portion of the site. A GooEngineers representative observed material types and conducted nuclear density testing and/or observed proofrof of in -place material. GeoEngineers reviewed settlement data provided by Baugh Construction for the fill placed in building areas. Based on our observations, the fill was placed and compacted in accordance with project requirements and recommendations. A eoEnginee s representative performed in place nuclear density tests on crushed rock base placed beneath the floor slab, and in utility trenches. Areas where the test results indicated inadequate relative compaction were generally reworked and =compacted.
