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.

This report provides an update on the ongoing efforts to address subgrade preparation and compaction in Area #1 of the project site. The report outlines the activities conducted, including proof rolling and scarification, and highlights the progress made thus far.

Activities:

• Continuation of Lift Placement:
  • Building upon the work from the previous day, efforts focused on placing lifts in Area #1 to enhance subgrade stability.
• Proof Rolling Assessment:
  • A proof-roll was conducted using a loaded tandem off-road dump truck (refer to attached photo).
  • The assessment covered an area of approximately 150 feet by 100 feet on the northeast side of the project site.
• Scarification Process:
  • Scarification and aeration were performed to address high moisture content levels in the previous lift.
• Recompaction:
  • Recompacting commenced using a Caterpillar CP54B ride-on vibratory sheeps-foot. However, the process was not completed by the end of the day due to time constraints.

Conclusion: The day’s activities focused on continuing the placement of lifts in Area #1, with specific attention to proof-rolling and scarification & aeration processes. While progress was made, recompacting efforts were not fully completed.
