Hunter Schwartzkopf
Mas Tec Power Corporation

Dunn and its subcontractors worked diligently and efficiently to construct the building, allowing initial production to our original schedule goal of December 31. For a project so big and complicated, and seeing that we did not get you under contract until late February, that was pretty fast! Throughout the project your team coordinated closely with our equipment vendors, and everyone maintained excellent quality.
