I wanted to take time to thank you and the rest of your crew for the outstanding work provided to the City of Bettendorf. […] The work performed on this project was done to a very high standard, on time and met or exceeded the expectations of the residents directly affected by the work. All equipment was used safely and efficiently. […] I want to add that your crew are very professional and dedicated people. You have every right to be proud of them and your firm. I look forward to working with you and your crew on future City projects.

I want to compliment your crew for their excellent work in our village. Your crew went out of their way to make the project less stressful for all the people directly affected by the work, and they made sure several elderly and handicapped had access to their homes.

My staff and I had the pleasure of working a fire scene with some of your staff. […] I just wanted you to know what a pleasure it was and how helpful your staff was in helping the Fire Marshal’s Office…. Two of your staff assisted us in pulling our large hose down the street to the hydrant until more fire personnel arrived. Your staff did an excellent job in securing the scene. […] We always appreciate the partnerships that ·we have with the private sector in town. Thanks again for a job well done.

I recently visited the project site and wanted to express our sincere gratitude for your work. […] Your firm has been very cooperative and committed to getting the job done, which is a refreshing change in this industry. […] pass along to the rest of your team our appreciation for your efforts.

[…] what a fine job your crew did repairing the water main break […] Your crew were hard working and courteous, making sure we could enter and exit our driveway during the construction.

At a recent council meeting, the subject of the concrete work that was done came up. There were many stories of your workers regarding their consideration, helpfulness, and the way they watched over us when we were getting to and from the building. This letter is to acknowledge a job well done and to say thank you for all your workers. Oh—yes—the concrete looks good too!
