APWA Project of the Year, 2015-2016

 

” D R Consultants (formerly Dean Ryan Consultants) Project Engineer, Dr. Fang Lee, P.E., Ph.D, more than justified the consultants professional fee with his idea of removing from the design the “air gap” vault. After a careful evaluation of his suggestion, we arrived at the conclusion that in fact the air gap vault was not needed. This design change, in my opinion, will save LADWP at least a couple of million dollars in construction and a few more million in operation costs during the life of the project.”

“Under your contract with the Federal Highway Administration, Dean Ryan Consultants completed a very complex Environmental Impact Statement (EIS) on proposed improvements to Forest highway 137, Wentworth Springs Road. I want to express my appreciation to your firm for its excellent work. This EIS on our highly controversial project was prepared under Court direction and had to be outstanding in every way. It was! I commend the excellence and professionalism of the Dean Ryan staff and their dedication to their work. The final EIS is thorough, well organized, well written, well illustrated, and logical in its analysis and conclusions. The work was performed under tight time constraints and was completed on time and to the highest quality.”
