What Our Clients Value


The global economy requires continuous movement of cargo along oceans, canals, and harbors. Whether building new infrastructure or renovating existing maritime pathways, Gannett Fleming keeps critical freight shipments moving efficiently. We have wide-ranging experience across a broad spectrum of engineering services. This means we account for the free flow of cargo before, during, and after construction.


Our nation’s ports and harbors are supported by a labyrinth of stakeholders, including agencies, port authorities, corporations, and leaseholders. We have experience partnering with these stakeholders and often work with the U.S. Army Corp. of Engineers (USACE). This reduces risk to schedule, budget, and operations.


The safety of our maritime infrastructure, facilities, and freight is vital to the United States supply chain and its national security. We take a diligent and methodical approach to port and harbor engineering, design, and construction. By doing this, we account for every potential threat while maintaining an efficient flow of goods.


Analyzing aerial and satellite imagery to digitize port infrastructure features has become increasingly important. Additionally, using this imagery to populate associated database attributes to support analytics is crucial. We’re able to help our clients by using geospatial solutions and real-time software as a service (SaaS) platforms. These solutions allow us to create data transparency for a frictionless flow of goods on a global scale.

Our Key Capabilities


The design and construction of harbor and port facilities requires a unique understanding of the many touchpoints involved. This is especially true with the movement of maritime freight. Key capabilities of our talented team of designers, planners, and engineers include:

  • Smooth navigation of vessels.
  • Efficient loading and offloading of cargo.
  • Adaptable yard operations.

Our specialists understand the dynamic conditions and specific needs of each facility. We take a consultative approach to port and harbor design while managing the construction of modern warehousing.


Gannett Fleming provides planning, engineering, and design services for maritime infrastructure and navigation, including:

  • Locks and dams.
  • Levees.
  • Dikes.
  • Revetments.

We do this while accounting for the smooth flow of commercial shipping and personal watercraft.

We have experience in our country’s inland waterways using tech-driven BIM design tools and 3D analytics. This ensures navigation projects are built with efficiency and sustainability in mind.
