Observations/Finding

9/13/22

As requested by CWM James Higgins, 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.

Site Observations:

Contractor continued work in the taxiway area from STA 4011+00 to STA 406+00, E-Line between and north of E1 to E2, backfilling over the water line outside the SIDA fence, and the south side of NLVR shoulder. Fill was placed and compaction testing requested.

Density testing was performed using a Troxler nuke gauge (#3430, serial #29588).

Density testing results:
P2 Moisture Density Relationship (proctor) – 141.4 pcf @ 5.7%
P3 Moisture Density Relationship (proctor) – 118.8 pcf @ 13.0%
P5 Moisture Density Relationship (proctor) – 122.6 pcf @ 9.6%
P14 Moisture Density Relationship (proctor) – 119.8 pcf @ 14.0%
Lime Proctor – 112.6 pcf @ 16.6%

T1 – south side of NLVR at 9L entrance GAB for flume, P2, DD 130.5, M% 2.1, compaction 92.3%
