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 density testing for Lots #1, 2, 3, 4 and 5 continued today.

At the time of arrival, the contractor had already placed soils and had compacted to finished grade using a 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 results:

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

T1-elevation at finish grade@ lot 1, Yd 100.9 M%22.2, Compaction: 101.9%

T2-elevation at finish grade@ lot 2, Yd 103.6 M% 22.2, Compaction: 104.6%

T3-elevation at finish grade@ lot 3 Yd 100.5 M% 21.9, Compaction: 101.5%

T4-elevation at finish grade@ lot 4, Yd 96.8 M% 25.4, Compaction: 97.7%

T5-elevation at finish grade@ lot 5, Yd 102 M%22, Compaction: 103%
