We are at the Lock and Dam 19 facility in Keokuk, Iowa, operated by the U.S. Army Corps of Engineers (USACE). Our team replaced an 18,000-LB, 105-FT underwater soundbar with wet-mateable connections (cables and speakers that can be connected and disconnected underwater). This underwater acoustic deterrent system (UADS) upgrade allows divers to replace individual speakers if underperforming rather than continuing to remove the entire system.

Why? The U.S. Geological Survey (USGS) is spearheading a 3-year study to reduce the number of invasive carp moving toward the Great Lakes. It is the only study on the Mississippi River evaluating a deterrent for invasive carp.

Island building and habitat restoration have significant environmental benefits, improving aquatic and land-based ecosystems. Working under LS Marine alongside Ramsey County, the U.S. Army Corps of Engineers, Saint Paul District, and the Minnesota Department of Natural Resources, Brennan built up islands at Pigs Eye Lake in Saint Paul, Minnesota.

The project's master plan features seven islands, sand beaches, marsh habitat, and land plantings. We utilized dredged material from the Mississippi River in an environmentally beneficial way to build the islands. Here's how it happened and why it works!

The US Environmental Protection Agency (EPA) and Minnesota Pollution Control Agency (MPCA) signed a project agreement to remediate contaminated sediment in the “ponds behind Erie Pier,” two ponds surrounded by shallow marsh wetlands in the St. Louis River Area of Concern (AOC).

The sediment was primarily contaminated with PCBs, PAHs, mercury, and chromium. Here's how we worked with stakeholders to clean up the sediment and the resulting impact of our work.

J.F. Brennan Company (Brennan) collaborated with The Boys & Girls Club of Greater La Crosse (Boys & Girls Club), Wieser Brothers General Contractor, Inc., and Mathy Construction to bring the expansive construction world to Boys & Girls Club members. The annual event is called Kids in Construction.

Club members explored Brennan’s amphibious equipment and commercial dive gear, tested out life as a chemist working in a water treatment lab, and experienced a career working in a support role in the construction industry. Our Brennan team members were on hand to answer all their questions and share more about the exciting world of construction. In this video, Boys & Girls Club CEO Jake Erickson shares his views on Brennan and the benefits of Kids In Construction.

Sandy Lake Dam is owned by the United States Army Corps of Engineers (USACE), St. Paul District. The USACE identified that the original concrete structure needed repairs and improvements to address immediate safety concerns. Because the dam structure was more than 100 years old, the USACE used this as an opportunity to have Brennan rehabilitate the dam and update many of its operational features.

Our new video shows you how we did it! 

The Cuyahoga Improvement Project in Kent, OH, aims to improve future recreation experiences while protecting existing natural resources. The purpose of our work is to remove areas of petroleum-impacted soft sediments that were deposited decades ago from discontinued industrial practices upstream. 

Background on a Burning River

The Cuyahoga River has quite a history: a transportation route; a boundary; an origin for oil, rubber, and steel industries; a power source; and a dumping ground. The river was once 1 of the most polluted in the country. The Cuyahoga has caught fire at least 13 times since the 1860s.

The 25th anniversary of Women in Construction Week™ (WIC Week™) has a clear theme: Many paths, one mission. The purpose is to recognize the different journeys women have taken to strengthen and amplify the success of all women in the construction industry. We're fortunate enough to feature some of those women, working at Brennan, who have agreed to share their thoughts on starting out in construction, and give advice to women considering joining the industry.
