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, compaction and density testing continued today for Lots #55, 56, 65 and 66.

At the time of arrival, the contractor already placed soils and compacted to finished grade using a GDP-515 compactor.

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

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

Density testing result:

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

T1-elevation at finish grade@ lot 55, Yd 98.9 M%22.3, Compaction: 99.9 %

T2-elevation at finish grade@ lot 56, Yd 100.1 M%22.3, Compaction: 101.1%

T3-elevation at finish grade@ lot 66 Yd 92.5 M%24.7, Compaction: 93.4 %

T4-elevation at finish grade@ lot 65, Yd 96.9 M%24.1, Compaction: 97.9%
