Three references from the public works engineers and inspectors Bryan has worked alongside. Send us a new one and we will add it here.
I have had the pleasure of working with Bryan Daher over the last six years as he served as the Public Works Inspector for the Town of Windsor. I found Bryan’s knowledge of public works infrastructure to be extremely deep, especially in regards to underground facilities, and I relied on his expertise often as projects went to construction in the town. Bryan is also extremely conscientious in his work ethics and values and I would welcome the opportunity to work with him again in the future.
I have had the pleasure of working with Bryan on a year long, complex City Wide Sewer Rehabilitation project where he was the project foreman for Hess Construction and I was the project Engineer for the City of Pittsburg Public Works Department. The project required a tremendous amount of public contact with residents on a daily basis due to project invasiveness. There was never a challenge from the project that Bryan couldn’t meet in the field and always offered solutions or alternatives to unforeseen changes to keep the project on schedule and moving forward.
Bryan’s knowledge of construction and permitting is outstanding. He cares about his clients, is efficient, trustworthy, and a solid individual who goes the extra mile.
The Difference
Over 20 years running civil construction, plus five years inspecting public works from the other side of the fence.
Bryan led crews and managed projects for established general engineering firms, then served over five years as a Public Works Inspector for the Town of Windsor.
