Partnering with public agencies to complete award-winning infrastructure projects – for more than 25 years

Nossaman's Infrastructure Practice Group has advised public agencies on the innovative procurement and financing of more infrastructure projects than any other U.S. law firm.  Our clients have benefited from our innovative project delivery and financing methods, realizing successful, award-winning projects

Chambers Logo - top ranked 2018With more than 30 attorneys, we are the largest and deepest infrastructure practice in the nation.  Having worked in 30+ states, we advise on transportation infrastructure, social infrastructure, and water and wastewater infrastructure projects ranging up to $10 billion.

Nossaman has played a leading role in almost every major, innovatively financed U.S. transportation infrastructure project.  This includes the first modern California toll roads, and turnpike projects in Texas, to such award-winning projects as Indiana's East End Crossing (Lewis and Clark Bridge) P3, California's Presidio Parkway P3, Virginia's Midtown Tunnel and the I-595 and Port of Miami Tunnel P3s in Florida (the nation's first and second availability-payment contracts).

This tradition continues as our attorneys are deeply involved with the nation's next generation of P3 infrastructure projects, including Florida's I-4 Ultimate, Nevada's Project Neon, North Carolina's I-77, Maryland's Purple Line LRT and the groundbreaking $68 billion California High-Speed Rail Project.

Nossaman pioneered the U.S. use of availability payments, toll concessions, pre-development agreements and design-build agreements. Many industry best practices are the direct result of our innovations in project procurement, contracting and financing.    

The delivery and financing of infrastructure projects face a complex regulatory network.  Nossaman helped create the policies and laws that govern all aspects of innovative infrastructure finance.  We define and then help our clients navigate this network.

While our commitment is to the public sector, many of our attorneys bring to the Firm previous experience and perspective gained working in-house for private clients and representing them at other law firms.  This provides our clients with beneficial insights into the private side of these deals without the concerns of any conflicts of interest during procurement and contract negotiations.
