Observations/Finding

As requested, the site was visited by our AS Engineering and Consulting (ASEC) representative noted above, 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.

Soil placement and compaction continued today for Lot #58 to Lot #63.

At the time of arrival, it was observed that the contractor had already placed soils and compacted to finished grade using a Hamm GDP-515 compactor.

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

Density test results indicate that the compacted materials met the project requirement of 90% of the maximum dry density obtained by the (Standard Proctor ASTM 698). 

Density testing result:

P-1 Moisture-Density Relationship = 99.0pcf @ 21.4%

T1-elevation at finish grade@ lot 58, Yd 103.5 M%22.2, Compaction: 104.5 %

T2-elevation at finish grade@ lot 59, Yd 102.9 M%22.1, Compaction: 103.9%

T3-elevation at finish grade@ lot 60, Yd 103.8 M%21.9, Compaction: 104.8%

T4-elevation at finish grade@ lot 61, Yd 103.5 M% 22.3, Compaction: 104.5%

T5-elevation at finish grade@ lot 62, Yd 102 M%22.2, Compaction:  103%

T6-elevation at finish grade@ lot 63, Yd 96.6 M%24.2, Compaction: 97.6%
