J.F. Brennan Company Video Resources

We are constantly creating new videos to highlight the work we are doing. Check back again soon to see more latest and greatest projects.


Explaining the important work our team and partners accomplish can be challenging. We find that videos help us share our experience, whether showing a technical side of our work or showing an exciting new innovation. 

Advantages of Amphibious Equipment | The Perfect Tool for Wetland Work 

Safely accessing environmental remediation, restoration, or construction projects located within wetlands is a challenge. Typically, contractors will create temporary roads to reach work areas. However, temporary roads are expensive and can negatively impact sensitive wetland environments and wildlife.

At Brennan, we have another option: customized amphibious equipment. When used during our projects, we can save our clients time and money, while greatly reducing negative impacts on the environment.

Girls in Construction Day - Exploring the Trades

On July 14, 2022, J.F. Brennan Company hosted an event in partnership with the Boys & Girls Club of Greater La Crosse, the Women's Fund of Greater La Crosse, Mathy Construction, and Wieser Brothers General Contractor called Girls in Construction. The event offered young women an opportunity to experience working at Brennan and to ask questions about working in the trades.

“As a woman in construction for more than 18 years, I am excited to show young girls in our community what our industry has to offer. By showing our use of innovation and technology, we hope to break through the stereotypes of construction for not only this group of girls but their friends and families in the area,” says Brennan CFO Tina Klinger, who greeted event attendees as they arrived at Brennan headquarters.

Participants toured a Brennan Marine tugboat, the Brennan shipping yard, shop, and corporate offices while participating in various demonstrations like piloting an underwater remote-operated vehicle (ROV) and operating virtual design in construction (VDC) software. Transportation for the day is provided by the Women’s Fund of Greater La Crosse.

The Waterplace Park River Restoration and Dredging Project | Providence, RI

In 2019, good fortune shone on Brennan's Environmental group as we procured a winter river restoration project in Rhode Island. The general scope for this project remained along the lines of past work, where we restore river depths to facilitate and improve water quality, fish migration, but this one came with a twist; its footprint was tightly nestled within the low bridges and bustling infrastructure of Waterplace Park in downtown Providence, RI.

Waukegan Diver-Assisted Dredging

BCS GAC Demonstration

Brennan has revolutionized sediment capping possibilities with its newly patented Broadcast Capping System (BCS™). This system uses the principles of hydraulic transport to deliver clean sand and granulated activated carbon to a distribution barge where it is rapidly dewatered and unobtrusively spread over the bottom of the waterway. Brennan’s sediment capping system can accurately place materials up to 3 inches in diameter, while achieving a homogenous thickness with even distribution.
