Observations/Finding

As requested, the site was visited by our AS Engineering and Consulting (ASEC) representative for the purpose of providing quality control inspection and testing services. Visual observation techniques were employed to verify compliance with project drawing/specifications, applicable codes, and materials
submittals. The following observations were observed on site this day.

Our ASEC representative was on site to observe the contractor (NG Grading) and for the observation/testing of the placement of fill/backfill.

The grading crew continued removal of topsoil from the footing of retaining wall #1. This area appears to have partially weathered rock (PWR) present in the footing. DCP testing will be performed once the footing has been excavated. The grading crew placed topsoil along the slopes of Lots #19 through #22. This area showed a serve amount of pumping. Because the pumping was within 10 feet of a house pad, it was recommended to remove the topsoil and replace with structural fill. The contractor agreed and excavated the topsoil and placed it further back on the slope.

The paving crew is finishing last touches to the deceleration lane before a proof-roll tomorrow morning.

The pipe crew began backfilling SSMH 2.2 to 2.3. Soil was installed in approximately 8-to-12-inch lifts and compacted with a combination of a trench roller and a vibrating sheep-foot roller. Density testing was performed and test results were provided to the contractor.

We appreciate the opportunity to be of service to you on this project. If you have any questions regarding this report, please feel free to contact us. We will be more than happy to discuss it with you.
