Observations/Finding

9/23/22

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 4010+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%

T1 – elevation 999.5, STA 409+00 center, P3, DD 118.3, M% 9.3, compaction 99%

T2 – elevation 999.5, STA 409+00 south, P3, DD 116.5, M% 10.2, compaction 98%

T3 – elevation 992.0, STA 408+00 center, P3, DD 108.9, M% 15.5, compaction 91.7%

Material that was placed after these tests was coming in wet, recommended to contractor to wait for morning shift to dry out material to continue placing.
