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.

Fighting Scour With Articulating Block Mats

Save Money with This Long-term Fix for Scour Problems

Scour poses a large threat to the stability of any structure that is partially or entirely underwater. It may develop slowly over time, or be brought on quickly by an intense rain event or seasonal flooding. In some cases, such as along a shoreline, scour can be very evident. In others, scour can go unnoticed for an extended period of time. Whether it is taking place around the footing of a bridge pier, along the base of a sheet pile wall, or along a tailrace on a dam, scour may not be evident until the structure begins to show signs above the water. At this point, the structure is beginning to fail and repairs must be done soon to avoid a total loss of integrity. Repairing scour and erosion issues that may be going unnoticed in any location is vital as it will save a lot of money in the long run, and extend the life of the structure.

Stabilizing Dams Using Post-Tensioned Anchors

Posted by Dave Laack on Tue, May 1, 2018

Post-tensioned rock and soil anchors provide an optimal solution  for dam stabilization.According to the Post-Tensioning Institute, post-tensioned rock and soil anchors provide a cost-efficient, high-performance solution for projects in need of temporary and permanent stabilization solutions. There are numerous different post-tension applications in the construction industry, but one of the most important areas is in dam stabilization.

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.

Discover the Value of Vinyl Sheet Piling

Posted by Samantha Schmitz on Fri, Sep 18, 2015

Traditionally when it comes to installing sheet piling around a bridge pier or along an embankment we think of steel sheet piling.  Steel sheet piling are the most common, and have been one of the most effective methods of installing a deep foundation.  They have a long history of providing a robust barrier through shaped, interlocking sheets that can last for 75+ years.
