We would be able to use their services on our out-of-state projects as needed. They would provide us with engineered sealed drawings and calculations quickly. Thank you for a professional job done well.


Been doing business with DOTec for a long time. While we are a regular/repeat company, our jobs are small potatoes compared to most—but that has never stopped us from receiving top notch service. I have recommended DOTec to many and will continue to when I have the chance.


DOTec did the final design and engineer-stamped drawings for my shipping container house. Based on my interface with them, they were responsive to my needs and did a good job. I have recommended DOTec to others and will use them again should the need arise.
