Why Getting a Contractor’s Constructability Review Prior to Bid Release Matters

Posted by Derek Armstrong and William Simons on November 16, 2021

Constructability reviews are imperative to project success. They can save you money, reduce the risk of cost escalation, and are often provided pro-bono by a good contractor. When it comes to requesting a contractor's constructability review, timing is important. If the review is performed too late, problems could result, including confusion surrounding the project, loss of significant time and money, and hefty change orders later in the project. The question then is: when is the optimal time to have a contractor perform a constructability review?

Successful Hydraulic Dredging Relies on Critical Velocity

Posted by Sam Crawford, Project Manager on August 13, 2020

As a leader in inland waterway dredging, J.F. Brennan Company (Brennan) serves as a success story for hydraulically dredging and pumping sediments over long distances and changing elevations. The goal of most dredging projects is to maximize efficiency, which means maximizing the average percent solids in the pipeline. However, there is a fine balance between maximizing percent solids and surpassing critical velocity to transport dredge slurry. Therefore, a dredge operator must understand the importance of critical velocity and how it varies as the material in the dredge cut changes.

Critical velocity, in this case, is the minimum speed at which sediment and water (slurry) must be pumped to prevent the sediment from settling and subsequently plugging the dredge pipeline. Plugging the pipeline is the bane of any dredging operation and one of the few things that will set a dredge operator trembling in their boots. After all, if a pipeline gets plugged, the dredge must shut down, which means the entire project stops.
