Observations/Finding

As requested, our ASEC representative visited the 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 #42 to Lot #50, Fill was placed 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 indicat that the compacted materials met the job specification of 90% of the maximum dry density obtained by the (Standard Proctor ASTM 698). See attached picture for approximate test locations,

Density testing result:

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

T1-elevation -1′ from finish grade, Yd 87.2, M%25.3, Compaction: 90.4%

T2-elevation -1′ from finish grade, Yd 87, M%24.2, Compaction: 90.2%

T3-elevation @ finish grade, Yd 93.5, M%26.2, Compaction: 98.9%

T4-elevation @ finish grade, Yd 89.69, M%26.1, Compaction: 92.9 %

T5-elevation @ finish grade, Yd 86.9, M%26.1, Compaction: 90.05%
