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.

On the above date our representative met with sub-contractors for paving, grading and curbing to discuss current subbase conditions concerning repairs for occurring erosion issues at Naturewalk parkway due to recent consistent rain events. The writer recommended using a lean concrete mix to fill eroded subbase reels that had occurred at the curb line and washed conditions at previous poured curbing which has recently been undermined. The sub-contractors elected to continue standard repair measures replacing eroded areas with GAB stone and adding check dams using silt fence. This should be sufficient if rain doesn’t occur prior to curb placement. There may be additional repair measures required at previous poured curbing.

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.
