Observations/Finding

As requested, our AS Engerineering 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.

Soils were compacted for Lots #30 to #33.

At the time of arrival, the contractor had already placed soils and compacted to finished grade. but moisture contents were observed to have exceeded maximum specified limit. 

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

Density test results indicate that the compacted materials met project specifications 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 30 and lot 31, Yd 103.7 M%25.2, Compaction: 104 %

T2-elevation at finish grade@ lot 32 and 33, Yd 101.27 M%25.1, Compaction: 102.3%
