USL Offshore safety training

Marine Survival Training Center

An example of DSA’s diverse design and engineering capabilities is the UL Marine Survival Training Center, the second of its kind in the world.

Located on the grounds of the Lafayette Regional Airport, the center caters to offshore oil and gas companies around the world by providing safety training relating to marine environments.

Backwash Water Settling Tanks

When the Louisiana Department of Environmental Quality (DEQ) regulated discharge of untreated backwash wastewater into public water streams, DSA went a step further by adopting tube settler technology to a new application.

The resulting backwash water is so clean it is not wasted, but rather recycled as usable water. This forward-thinking solution saves the city 55 million gallons of treated water per year.

Parc Auto du Centre Ville

Still in service after decades of use by the public, this facility provides several hundred parking spaces in our busy downtown. It was recently adapted to make use of mobile phone parking apps.

Airport Expertise

Key to a community’s economic development is its airport. DSA has continuously been designing improvements for the Lafayette Regional airport since 1961 and is on the team designing the latest terminal improvements.
