Observations/Finding

As requested, our AS Engineering and Consulting (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.

Compaction of fill placed for Lot #58 continued.

At the time of arrival, the contractor had already placed soils and compacted to finished grade. Moisture contents were checked and found to exceed maximum specified limits. 

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

Density test results indicate that the compacted material 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) = 100.4 pcf @18.6%

T1-elevation at finish grade@ lot 58, Yd 103.4 M%17.5, Compaction: 102.98 %

T2-elevation at finish grade@ lot 58, Yd 96.1M%19.5, Compaction: 95.7%
