Evaluate: Lots 145 & 146 footing subgrade,Temporary parking lot, structural fill Outstanding Issues: Proof roll road and curb base rock and repair as needed before paving FR-58 (12/06)Decommission temporary storm and sewer lines through Tract E At time of arrival I observed three earth work crew onsite in the process of preparing subgrade and fill. „Lots 145& 146 I observed that one of the onsite earthwork crew was in the process of cutting footing subgrade for model homes within lots 145& 146.I observed the subgrade to consist generally of structural fill material with areas of exposed basalt. Using a%2"diameter steel foundation rod I probed the footing subgrade for the building within these lots. Probing indicated stiff subgrade (Probing basalt I hit immediate refusal). I was informed there will be no footing base rock. Temporary Parking Lot I observed that one of the onsite earthwork crew was in the process of preparwarea within lots 139& 140 for a temporary parking lot for model homes. I was informed that crew placed approx.4"of%" minus crushed rock on the surface of structural fill subgrade and there will be an approx. 2"AC section. Compaction efforts were completed utilizing a large single smooth drum roller. I observed no to negliable deflection under the roller during compaction efforts. Using a Y2"diameter steel foundation rod I probed the,parking area base rock. Probing indicated dense base rock. I was informed AC section would be removed at a later date and subgrade repair before construction of building. .Structural Fill While onsite I was informed by NEI that they had placed approx. l'to 1.5' of native fill material within lots '166-170 (see site plan for details). Compaction efforts were completed utilizing a CAT 815$)pad foot compactor. Using Troxler 3430 nuclear density gauge I tested the relative density of the fill and compared the results to a field adjusted proctor value of 116.0pcf'at 16.3 percent optimum moisture content(proctor value was adjusted due to amount of rock present in testing areas). 92%compaction of optimum dry density value is required to meet our recommendations. Areas tested met our recommendations. I observed 17 and 20 blows on a Y2"diameter steel pin with a 6-lbs hammer to drive pin approx. 12" into material, indicating density compacted fill. Based on our observations, testing,and,,probing, areas of observed fill, subgrade, parking area base rock,indicated on attached site plan have been prepared in general accordance with our geotechnical recommendations. 15575 SW Sequoia Parkway,Suite 100 I Portland,OR 97224 I Off 503.968.8787 I fax 503.968.3068 GEODESIGNzFIELD REPORT Page 2 of 2 Distribution: Attachments: Site Plans (1), NDDS(1) Reviewed by: SMD This report presents opinions formed as a result of our observation of activities relating to geotechnical engineering or environmental services.We rely on the contractor to comply with the plans and specifications throughout the duration of the project irrespective of the presence of our representative.Our work does not include supervision or direction of the contractor,the contractor's employees or agents.Our firm Is not responsible for site safety.This field report is a DRAFT representation of our field observations,testing;and preliminary recommendations, can only be considered final upon review of the Geopesign project manager,as indicated by initials in the"Reviewed By"section.
