We would like to take this opportunity to express our appreciation for the excellent work performed by the ACECO project team at GWU Thurston Hall. ACECO field leadership has great command of the work crew and creates a productive, efficient, and respectful work environment. We encountered several changed conditions and uncovered several unknown obstacles; and through it all, ACECO brought a positive “let’s get this done” attitude. The project had a very demanding schedule and ACECO was always ready for the challenge, and creative and open-minded to finding a better, more productive way to get the work done. ACECO provided an excellent safety culture on the project. And we also want to recognize ACECO for outstanding clean-up throughout the project. Please pass on our appreciation to everyone on the ACECO Team for all of the hard work.
