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.

• The placement and compaction of backfill M10 and GAB located at bend 30 at STA 7021+32.82 and observed the subcontractor (Lewis contracting) as they began backfilling in the area of the manhole placed at the 30″ in-line valve approximately at STA 7016+27, and also observed the placement of 9 cubic yards, 3000 psi concrete for bent 30 approximately at STA 7021+32.82.
• At the time of arrival, our representative observed that work was in progress with 6-inch lifts being placed and compacted using a trench and jumping jack plat compactor.
• Density test results indicate that the compacted materials met the project requirement of 95% of the maximum dry density obtained by the Modified  Proctor ASTM D1557.
