Ladies and Gentlemen: In accordance with a request from Turner Construction Company, we have prepared this letter to confirm that Christian Wheeler Engineering has provided geotechnical observations and testing services during the mass grading operations for the proposed ticket booth to be constructed as part of the subject project. It is the opinion of Christian Wheeler Engineering that the soil engineering and engineering geologic aspects of the grading are in compliance with the approved geotechnical report. This opinion is based upon our observations of the earthwork operations, the results of the density tests taken in the field, and the maximum density tests performed in our laboratory. It is our further opinion that this portion of the site is suitable for the proposed construction. A final as-graded report for the entire project will be submitted upon completion of grading operations. If you have any questions regarding this report, please do not hesitate to contact this office. This opportunity to be of professional service is sincerely appreciated.
