Observations/Finding

9/14/22

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

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

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

T1 – elevation 991.0, 20′ east of E1, LP, DD 106.6, M% 13.9, compaction 94.7%

T2 – elevation 991.0, 5’north of E2.1, LP, DD 106.4, M% 14.0, compaction 94.5%

T3 – elevation 991.0, 15′ west of E2, LP, DD 107.4, M% 14.0, compaction 95.4%

T4 – elevation 990.0, 30′ north of E2.1, LP, DD 107.5, M% 14.1, compaction 95.5%

T5 – Outside SIDA water line STA 106+00, P3, DD 110.7, M% 9.2, compaction 93.2%

T6 – elevation 996.0, STA 411+50 north, P3, DD 116.3, M% 14.2, compaction 97.9%

T7 – elevation 996.0, STA 411+50 center, P3, DD 116.7, M% 12.8, compaction 98.2%

T8 – STA 406+20, P3, DD 111.6, M% 12.8, compaction 93.9%

T9 – elevation 991.6, 5’north of E2.1, LP, DD 106.4, M% 15.3, compaction 94.5%

T10 – elevation 991.6, 15′ west of E2, LP, DD 101.7, M% 16.5, compaction 90.3%
