Observations/Finding

As requested, our ASEC representative arrived on site for the purpose of providing quality control inspection and testing services, visual observation techniques were employed to assure compliance with project drawing/specifications, applicable codes, and materials submittals. the following observations were observed on site this day.

Contractor continued work on Lot #64 to Lot #65, Fill was placed and spread using a dozer. Compaction was performed using a sheeps-foot roller.

Density testing was performed using a Troxler nuclear gauge (#3430, serial #85759). 

Density test results indicate that the compacted materials did not meet project specifications of 90% of the maximum dry density obtained by the (Standard Proctor ASTM 698). This was due to the presence of high moisture contents. It was recommended to wait for drier weather and scarify and aerate the wet soils.  Contractor elected to remove the wet soils and stockpile to a later date and bring in drier materials.

Density testing result:

Moisture-Density Relationship (proctor) = 96.5 @ 22.2%

T1-elevation 1foot @ from finish grade, Yd 84.2, M%32, Compaction: 87.2%

T2-elevation 2 feet @ finish grade, Yd 85.7, M%32, Compaction: 88.8%
