The crew continued earthwork operations at Lots 53, 52, 51, and 50, where backfilling activities were carried out using suitable fill material. The soil was placed in controlled lifts of approximately 6–8 inches thickness to ensure proper compaction and stability. Each lift was spread and leveled using a crawler bulldozer, which helped distribute the material evenly across the working area.

After spreading, the placed lifts were compacted using a sheep foot roller and Caterpillar 815 compactor to achieve the required density and soil stability. The compaction process was performed systematically across the area to ensure uniform consolidation of the fill material.

During field observations, it was noted that in certain locations the fill material was placed in lifts thicker than the recommended 6–8 inches. Placing thicker lifts can make it difficult for the compaction equipment to achieve the required density throughout the entire layer. Crew continued compaction operations using the sheep foot roller and Caterpillar 815 equipment, and the areas appeared to be compacted adequately after multiple passes.

After compaction, it was observed that a couple of locations did not meet the required compaction standards. In those areas, the contractor reworked the soil by loosening the material, re-compacting the lifts using the same equipment. After reworking, additional compaction passes were performed, and the areas were compacted again until the required compaction criteria were satisfactorily achieved.

Recommended:

Back fill material in controlled lifts of each 6-8 inch.
