Accolades for Dutra Marine Construction

"I would like to thank Dutra Construction Company for its commitment to excellence and customer service. Every facet of the deconstruction of the existing pier and construction of the new pier resonated with quality and professionalism.

The success of this project was evidenced by Dutra’s project engineering, planning, quality of workmanship and, ultimately, concerns for protecting the sensitive natural resources associated with the construction site.

It is a pleasure to work with such professional people. Thank you again!"
