The Science Behind Radial Gate Tensioning

Posted by Dillon Hogan on Tue, Nov 27, 2018

At Brennan, we have worked on many different kinds of dams of various sizes and functions. As very few new dams are built each year in the U.S., most of our work consists of rehabilitation and repairs. Dams are built to last for long periods of time, however certain components will require periodic repairs and replacements. For instance, radial gates are some of the most common components that need attention. In our experience, we have found some best practices that will increase the lifespan of these gates, as well as increase their functionality.

Waterway Infrastructure from the Eyes of Those Who Build It

Posted by Mark Binsfeld on Thu, Mar 22, 2018

There is a lot of buzz around the president’s infrastructure plan lately. It is clear that everyone wants better infrastructure, regardless to which party an individual may belong. The biggest challenge to getting what everyone wants is funding, and making matters more difficult, the allocation of this funding is another source of disagreement. As a contractor that provides construction services to owners of infrastructure, it is clear that the waterways are suffering the most from lack of investment.
