Observations/Finding

As requested, an ASEC Inspector was present at the above referenced site for the purpose of observing the placement of structural fill at the area of pipe backfill from manhole A6 (area approximate size 30 feet by 60 feet). Based on review of guidelines for fill placement, the required compaction for structural fill at the above-mentioned area was 95 % of standard proctor. Based on visual observation and field measuring, the fill was placed in 8 to 12 inch thick lifts and compacted using a CAT CP44b sheepsfoot compactor (weight; 16,471 lbs.). Based on density testing, the fill placed today at depths between approximately -5 feet and -3 feet below finished grade was compacted according to fill placement guidelines. See attached density test results for more details.

ASEC recommends sealing of the surface of placed fill from inclement weather and to maintain positive drainage.

The contractor was notified about results.
