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 is continuing the excavation of retaining wall #1. Soil excavated from this area is being spread across the cut areas in the commercial lots. Further DCP testing will be performed when the footing excavation is completed.

The paving crew began placing binder asphalt in the deceleration lane and lane extension. ASEC measured station numbers and performed density testing approximately every 50 to 100 lineal feet. Test results were provided to the contractor. A loose sample was taken from the first truck to conduct further lab testing. The contractors placed approximately 3 to 4 inches of binder and rolled in the binder with a combination of a smooth drum roller CB2.7 and CB4.4. The paver is a P385c. A roll pattern was established and mapped out (included in the pictures). ASEC recorded temps of binder from the trucks before being placed in the hopper, and time that the trucks were on site. After compaction, the binder was measured to approximately 2.5 to 3 inches thick.
