New York  – Langan Engineering & Environmental Services, a premier land development engineering and environmental consulting firm, proudly announced that one of its Senior Principals, Rudolph P. Frizzi, P.E., G.E., is the new President of the Deep Foundations Institute (DFI).

Frizzi has 22 years of consulting geotechnical engineering experience – all with Langan – in numerous aspects of foundation design and construction on projects throughout North America and around the world. In addition to leading many major projects in the New York Metropolitan region, Frizzi is the Principal-in-Charge of the firm’s Las Vegas and Los Angeles offices. He has designed the foundation for the tallest building in Florida (The Four Seasons Hotel and Tower) and is responsible for the foundation design of the tallest building on the Las Vegas strip (The Fontainebleau Casino and Resort).

Frizzi has authored and presented technical papers and participated as an invited panelist at DFI, ASCE/GI, and ADSC Conferences, as well as at several universities on topics ranging from ground improvement by surcharging to driven, augered, and drilled shaft deep foundation systems. A DFI member since 1989, Frizzi was Chairman of the DFI's Augered Cast-in-Place Pile Committee.

“I am honored to assume the Presidency of DFI and I look forward to continuing the important work of my predecessor, Seth Pearlman, over the next two years,” said Frizzi. “2009 marks my 20th year as a DFI member and I can personally attest to the progress we have made and will do my best to advance our mission in the United States and internationally.”

Frizzi, who holds an MSCE from the University of Illinois at Urbana-Champaign, a BSCE degree from the Ohio State University, is a licensed Professional Engineer in nine states, and a licensed geotechnical engineer in California.
