Arrived on site at the request of the contractor to observe the removal of the loose debris in the uncovered areas, and to observe the backfill of the voids. The exposed void at grid point E, 1.25 had loose material that was removed with a mini-track hoe. During the removal, a void directly north was exposed (along gridline E). The void extends a minimum of 5 feet outside the building footprint. Loose fill (spoils)was 18 inches to 2 feet below the footing subgrade and slopes down into the void as far as visible. There is a 5 to 6 foot span of unsupported footing visible. It may be possible to install helical anchors on either side of the unsupported span to support the increased footing loads in this area. This solution would need to be re-engineered and approved by the project structural engineer. Filling the void with CDF is also a possible solution. It is important that the CDF/concrete used make contact with the entire exposed subgrade surface of the footing. A '/2 inch diameter steel rod was used to probe the footing subgrades at A, 5 to A,7 to B,7 and B,4 to B,7. The spread footing subgrades at B, 5;B,6; C, 5; and C,6 were also checked. All footing subgrades were found to be firm and unyielding and seem to be competent material and is suitable for further construction. The material that was being removed during excavation remains unsuitable for use as backfill due to the high debris content. A Geocon Northwest representative will return to the site tomorrow,as requested. FIELD TECHNICIAN(PRINT) DATE HOURS O T.

Arrived on site at the request of the contractor to observe footing excavations and void clean-up. The void at E, 1.25 was filled with 4 inch minus rock to approximately 2 feet below the subgrade of the existing footing. The rock was then sloped so that CDF would flow beneath the footing and into the void behind the footing. The CDF was poured into the void and above the subgrade of the footing until a static position was reached. A rock"dam" was pushed towards the footing so head pressure could be built and CDF was then added.The rock was then compacted and CDF was added to the entire void to 32 inches below the existing grade. The void at C.8, 3.5 was filled with 4 inch minus rock to approximately 6 inches above the subgrade of the existing footing and compacted.The void subgrade was approximately 10 feet below the existing grade. A '/2 inch diameter steel rod was used to check the grade beam footing subgrades at C, 7 to F, 7 to F, 6; and the spread footing subgrades at D,6 and E,6.All footing subgrades were found to be firm and unyielding with exception of the spread footing at D, 6 which required a 3'x9'x10" over-excavation to reach competent material that was suitable for further construction. An over- excavation of 4'x8'x2' was required at approximately E,6.5 to reach competent material. A Geocon Northwest representative will return to the site tomorrow,as requested.

Arrived on site at the request of the contractor to evaluate the subgrade after the site was stripped of vegetation. Upon arrival,the contractor was still stripping the site and the stripping material was stockpiled in the middle of the site.Geocon met with Bones Construction and stated that in order to properly evaluate the subgrade, the large stripping pile will need to be removed. Darren (Bones Construction) stated that the material for fill placement is out behind Coffee Creek Correction at the North Wilsonville exit. Darren requested that Geocon evaluate the material today. Brian Compton Trucking was supposed to be at the site with excavation equipment. Geocon visited the source site;however, nobody was on site. Geocon called Darren and stated that the material was not available to look at. Darren called back and stated that Brian would be on the site over the 2°d and 3`d of July to clear the stockpiles of tall grass and steel debris setting in the borrow area. A site visit was conducted on 7/2/11 at the source location,however,nobody was on site and the area still had grass and debris in stockpiles.

Arrived on site at the request of the contractor to evaluate an inflow water issue at the roadway expansion on 72nd Avenue and the corner of 72nd Avenue and Dartmouth Street. At the 72'Avenue expansion, a considerable inflow of water on the excavated subgrade for the roadway was observed.At the corner of 72nd Avenue and Dartmouth Street there was water inflow from an existing trench line that runs to a manhole on the property. The inflow off of Dartmouth Street is in a structural area of the Dartmouth roadway expansion and sidewalk. It is Geocon's opinion that some type of drain system be installed at both locations prior to any base rock placement. The contractor had approximately 12 to 15 cubic yards of material that was excavated on site and wanted to use it as fill material.

Arrived on site at the request of the contractor to evaluate the stripped subgrade at selected areas of the site. A fully loaded 10 to 12 cubic yard dump truck was used to proof-roll the stripped subgrade on a portion of the north 1/3 of the site,the south 1/3 of the site,and the roadway extension footprint.The subgrade was observed to be firm and ready for continued construction with the exception of an area that was 30 feet by 30 feet in the western end of the north 1/3 of the site. This area requires an over-excavation of one foot to remove soft material that has some organic material. The stripping stockpile remains on site;therefore,Geocon was not able to evaluate the stripped subgrade.Additionally, Geocon was not able to observe a proof-roll of an area in the north 1/3 of the site due to the stockpile of unsuitable material that was mentioned in the previous field report.

Approximately 100 cubic yards of material was observed to be satisfactory for fill placements. The contractor has not over- excavated the west 1/3 of the building footprint or the area in the new roadway alignment. Geocon conducted a site visit at Bones Construction site in Tualatin,Oregon to obtain a soil sample of the proposed fill material to be used at Red Rock Center,Two,5 gallon buckets and three sealed bag samples were collected for testing purposes. Geocon will obtain the in-place moisture range from the sealed bag samples. It appears that the material has a high moisture content in-field.The material was observed to be satisfactory for use as fill placement with optimum moisture testing to follow.

We collected the moisture content bag samples of fill material at Bones site in Tualatin. The in-field moisture content ranged from 23.8% to 30%. The max thy density and optimum moisture results of the proctor test performed at our laboratory were determined to be 107 pcf at 18%. Therefore moisture conditioning will need to be performed prior to any placement of this fill material.This information was communicated to Darren with Bones Construction. We conducted preliminary in-place density testing of the fill material that had been placed and compacted in the existing ditch- line at the north end of the building footprint.The test results revealed the fill placed to be high of optimum moisture at 25.9% and at 89% max dry density. This further indicates that the import fill material will require moisture conditioning prior to placement. We conducted an afternoon site visit at the request of the contractor to evaluate fill placement after mixing the import material with drier onsite soil in an attempt to reduce the moisture content. In-place density testing revealed compaction to range from 88%to 91%with moisture content ranging from 24%to 25%.This does not meet the design specification requirement. Had phone conversation with Matt with Bones and conveyed the results of testing today and was advised that Bones would halt trucking this afternoon until issues with moisture can be resolved, A Geocon Northwest representative will return to the site upon request.

Arrived on site at the request of the contractor to evaluate the placement of fill on the building pad footprint and the new roadway alignment. Geocon received a call from Brian Keicher requesting a notification when Geocon would be on site so that he could make a visit at the same time.Geocon received the call after the 8:00 AM visit. Geocon called Brian Keicher at 11:00 AM and left a message that the contractor requested an afternoon visit at 1:00 PM to conduct in-place density testing at the western 1/3 of the building pad footprint. In-place density testing was conducted on the first 1 foot fill placement on the west 1/3 of the building pad footprint. The test revealed moisture of 23.5%which does not meet design specification requirements,requiring additional moisture conditioning. A site visit was conducted at 1:00 PM as requested by the contractor. Geocon observed that the contractor had trucked approximately 15 loads of fill material in on 7/27/11 and spread out to condition the material's moisture. In-place moisture testing was conducted at various locations in the farmed material. This material had been spread in the late afternoon on 7/27/11. The moisture range was observed to be 18.5% to 20%, which is in the range of the specification requirements. During the afternoon visit,Brian Keicher did not visit the site. The contractor requested a site visit on 7/29/11 in the morning, at which time there will be a meeting with Matt (Bones Construction), Brian Keicher, Red Rock business associates, and Robert Pendell(Geocon Northwest).

Upon arrival, Geocon observed that Carlson Testing was on site to conduct in-place testing of the fill placement at locations where Geocon took tests. Apparently this follow up of Geocon's testing pertains to the moisture contents of Bones Construction's fill material. In-place density testing was conducted on the fill placements at various locations on site.Test results and locations are shown on the attached sheet. Test results revealed that tests 1 through 5 met the design specification requirements and tests 6 through 8 did not meet the design specification requirements,which require additional moisture conditioning. A fully loaded 10 to 12 cubic yard dump truck was used to proof-roll the center 1/3 of the building pad footprint after the stockpiled material was removed.The subgrade was observed to be satisfactory with the exception of a small area that has drawn moisture from the stockpiled material. The contractor plans to leave this area uncovered to dry back with the current high temperature before fill placements. Geocon met with Red Rock business associates, Brian Keicher, and Matt (Bones Construction) explaining Geocon's observations to date in respect to the moisture of the fill material that was imported to the site. Geocon explained that the moisture content of the material that was trucked to the site is high of optimum moisture content. However, after moisture conditioning the material back to 18% to 20%, compaction of the fill placements meet or exceed the required 95% compaction of the maximum dry density obtained in laboratory testing. Matt (Bones Construction) stated in the meeting that they do not have the budget to conduct the moisture conditioning process.This issue is one that only Brian Keicher can address.
