Working with Dennis, and the team at Duffy Engineering, is always a great pleasure for us at Austin Concrete Development. Dennis and his team are always professional and their engineering designs are always of the highest standards and quality. More importantly to me, in over the last 16 plus years of working with Duffy Engineering, Dennis and his team have always made themselves available to me and my team to discuss the many challenges we have encountered over the years on the very large and complicated projects we have executed together. In my opinion, one of Dennis strongest qualities is his willingness to work and communicate with the Contractors that are tasked with executing his design. He and his team are always open and encouraging to have the input of all of the qualified Contractors that they work with. This is a priceless virtue and necessity to a successful project and that is why Duffy Engineering has the reputations it has, as one of the most respected Engineering Firms in the Austin Market. I look forward to many years of future work with Dennis and his team at Duffy Engineering.
