Observations/Finding

9/22/22

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 area from STA 4011+00 to STA 408+00. Fill was placed and compaction testing was 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 Moisture Density Relationship (proctor)- 122.6 pcf @ 9.6%

T1 – elevation 997.3, STA 409+50 center, P5, DD 112.8, M% 8.6, compaction 92%

T2 – elevation 997.3, STA 409+50 north, P5, DD 122.7, M% 9.6, compaction 100%

T3 – elevation 998.1, STA 410+50 center, P5, DD 120.0, M% 12.0, compaction 97.8%

T4 – elevation 995.1, STA 408+50 center, P3, DD 113.2, M% 12.8, compaction 95.3%

T5 – elevation 995.1, STA 408+50 north, P3, DD 107.0, M% 12.3, compaction 90.0%

T6 – elevation 998.45, STA 409+50 center, P3, DD 112.1, M% 14.5, compaction 94.4

T7 – elevation 998.45, STA 409+50 north, P3, DD 113.4, M% 15.3, compaction 95.5%

T8 – elevation 995.9. STA 408+50, P3, DD 107.1, M% 11.9, compaction 90.2%

T9 – elevation 995.9, STA 408+50 south, DD 106.9, M% 15.2, compaction 90.0%
