Observations/Finding

8/15/22

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, backfill of wall outside SIDA fence, and the area around the A8 structure. Moisture contents of in-situ soils in all areas were high from recent rains and efforts were made to bring moistures down to continue lift placement.
A proof-roll was performed in the area just east of Zone 4.  Some pumping and/or rutting was observed and this area needs to be remediated.
Backfill outside SIDA fence at Crosswinds Rd/Airport Blvd was found to have organic materials and the contractor was requested to remove these organics.

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

All density testing results were found to be below job specification requirements due to much higher than optimum moisture contents.
