Observations/Finding

Our AS Engineering & Consulting (ASEC) representative arrived on site to observe field activities. The following tasks were performed:

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.

• The placement and compaction of backfill soils for the water line from Lot #1 to Lot #5 continued this day.
• At the time of arrival, our representative observed that work was in progress with 1-foot lifts being placed and compacted with a 6-ton pad feet and trench compactors. Compaction testing was performed using the Standard Test Method for Density of Soil in Place by Drive-Cylinder (ASTM D 2937), along with general probing using a 3/8″ diameter probe rod.
• Density test results indicate that most of the compacted materials met the project requirement of 95% of the maximum dry density obtained by a Standard Proctor ASTM 698.
