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.

Contractor continued backfilling and compaction for Lots #421, #422, #423 and the roadway.

Upon arrival, work was already in progress with the contractor placing and compacting lifts with a lift thickness of 24 inches.

The soils observed on this date did not appear to be placed in accordance with project specifications.  Soils were placed in too thick of lifts.

The contractor was notified about the excessive lift thicknesses, and we recommended ach lift be placed approximately 12 inches. Soil was brought by 2 dump trucks; spreading was done by a Komatsu 51 pxi and compacted using a caterpillar 815 F.

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). Note: Soils were found to have large rock fragments (see attached photos).

Density testing result:

P-01 Moisture-Density Relationship (proctor) = 100.4pcf @1 8.6%

T1-elevation -11 feet from finish grade@ lot 422, Yd 100.6 M%16.6, Compaction: 100.2 %

T2-elevation -6 feet from finish grade@ road, Yd 99.9, M%17.4, Compaction:99.5 %

T3-elevation -12 feet from finish grade@ road Yd 99.1, M%16.9, Compaction: 98.7 %

T4-elevation -7 feet from finish grade@ lot423, Yd 92.0, M%20.5, Compaction: 91.6 %

T5-elevation -1 foot from finish grade@ lot421, Yd 101.9, M%17.3, Compaction: 101.5 %
