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.

Area 3:
No. 89 stone was placed as a base layer. Following this, fill material was placed in lifts. Each lift was compacted using a trench compactor. The work progressed systematically lift.

Area 4:
Fill material was placed and compacted using a sheep-foot roller. Density tests were performed and did not meet the required compaction due to high moisture contents present. To address this, the crew mixed GAB with the existing material to reduce moisture contents. The area was then re-compacted, and subsequent stability tests were found to be stable and was approved by the QA, 2MNext. Work continued with placement and compaction of additional lifts in a controlled manner.

Area 6:
GAB material was placed as fill and compacted using a trench compactor, sheep-foot roller and smooth drum roller. Compaction activities were carried out and the stability of the layer checked.
