Observations/Finding

8/14/22

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 on the taxiway and shoulder, H-Line, Localizer, and the area around the A8 structure. Moisture contents of in-situ soils were found to be high from recent rains.  Efforts were made to bring moistures down so as to continue fill placement. Fill was placed and compaction testing requested.

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

Density testing results:
P14 Moisture Density Relationship (proctor) – 119.8 @ 14.0

T1 – elevation 1006.0, taxiway STA 439+00, P14, DD 110.3, M% 14.7, compaction 92.1%

T2 – elevation 1006.0. taxiway STA 440+00, P14, DD 114.9, M%, 12.1, compaction 96.0%

T3 – elevation 1006.0, shoulder STA 439+00, P14, DD 112.4, M% 14.0, compaction 93.8%

T4 – elevation 1006.0, shoulder STA 440+00, P14, DD 113.8, M% 11.6, compaction 95.0%

T5 – elevation 1001.5, 30′ east of H1, P14, DD 118.0, M% 11.2, compaction 98.5%

T6 – elevation 1001.5, H2, P14, DD 110.1, M% 14.8, compaction 92.0%
