Brennan Company (Brennan). For a third straight year, Brennan has had the opportunity to procure work in the milder maritime climate throughout New England during the winter months. These months are key for in-water work on the east coast as they provide opportunities to revitalize salt marshes, re-nourish beaches and restore navigation outside of the fish migration and spawning windows. Generally, this work has been undertaken in and near the coastal salt marshes adjacent to the smaller resort communities.

Brennan Company, Inc. (Brennan) faces a unique array of regulations and rules.

There are always two parts of a water-based project, the above and below water sections. Access to the above water section is easy, however when working below the waterline access is not that easy. One of the more apparent issues is what do you do when the water is in the way of your work? One solution is to build a cofferdam.

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.
