FOUNDATION EXCAVATION REVIEW
LOT 20 — BRITTANY MEADOWS
TIGARD, OREGON
Reference: GeoPacific Engineering, Inc. Soil Engineer's Summary At Conclusion of Earthwork,
Brittany Meadows, Job No. 9331, August 21, 2007.
GeoPacific Engineering Inc. visited the site to review the house foundation excavation subgrade for
bearing conditions only on a gently sloping housesite. We understand that the proposed residence is
a two -story single - family home. The excavation generally exposed engineered fill with sand and
gravel. The observed subgrade is adequate for spread foundation support to a maximum allowable
bearing pressure of more than 1,500 psf. If footings are located within the zone of influence of vertical
cuts, then some gravel backfill may be necessary to support the vertical face.
It is also possible that the subgrade could become softened by rain; in such event, it should be
mucked out from beneath footings just prior to pour. No deck footing, patio, or other appurtenant
structure subgrades were observed.
Our work scope pertains to a geotechnical engineer's foundation excavation review only and the
conditions existing and exposed at the time of our site visit. No warranty is herein expressed or
implied. This report was prepared for Advanced Construction and Repair only and should not be
relied upon by third parties without consulting GeoPacific. If you have any questions, please call.
Sincerely,
GeoPacific Engineering, Inc. _
