Observations/Finding

AS ENGINEERING AND CONSULTING, LLC (ASEC) visited the site at the contractor’s request to observe soil placement and test the compaction of the soils placed beneath the conduit for the dam. The entire area was probed, and the compaction test results met job specifications. The conduit section is 170 feet long, and the diameter is 37 inches.

 

Monday- Tuesday:

Trench excavations commenced, and soils were inspected and passed compaction. Conduits sections were being placed and cemented together. Images (1 -6)

Wednesday:

The conduit and maintenance access were placed. The area for the manhole was excavated, and rock was placed at the base of the manhole. Water was observed intruding into the area with the manhole.  We recommended the water be pumped out prior to concrete placement. Concrete was placed for the anti-seep collar and the bottom three-foot section of the manhole.

Thursday, Friday & Saturday:

Soil backfill was placed and compacted in 4-inch lifts.

On 8-3 footings were excavated for the anti-seep collar. Water begins to fill the bottom 6 inches of the footing. Soils in the footing were saturated but well compacted.

The rebar was placed within at 12-inch spacing to form the anti-seep collar.

On 8-6, the contractor sprinkled water onto the soil to increase moisture.

8-6 anti-seep collar was finished. Soils were tested on each side of the collar and passed compaction.

Soils are placed in 4-inch lifts near the anti-seep collar.
