Observations/Finding

As requested, the site was visited by our AS Engineering and Consulting (ASEC) representative for the purpose of providing quality control inspection and testing services. Visual observation techniques were employed to verify compliance with project drawing/specifications, applicable codes, and materials
submittals. The following observations were observed on site this day.

Our ASEC representative was on site to observe the contractor (CWM) and for the observation/testing of the placement of asphalt. The contractors milled in-between Hanger F and G. A visual inspection was performed on the subgrade soils. It appeared to have a small portion of asphalt that was still left after the 2 inch milling. This asphalt appears to be cracking and unstable. UES notified Lead Edge of the subgrade conditions and will be meeting on-site Saturday to discuss. At this time, it appears the contractors are going to pave the 3rd lane of the taxiway, and leave Hangar F and G milled, until an inspection is conducted on the following day. Density testing was performed, and test results were provided to the contractor.

We appreciate the opportunity to be of service to you on this project. If you have any questions regarding this report, please feel free to contact us. We will be more than happy to discuss it with you.
