Lawrence G. Griffis is a Senior Principal and President of the Structures Division at Walter P. Moore and Associates. He is responsible for directing three operating groups of the division including Structural Engineering, Structural Diagnostics and Parking. Mr. Griffis has directed or made significant contributions to the structural design of over 80 major buildings throughout the United States and internationally. He has combined his 39 years of practical design and management experience with ongoing involvement in numerous technical committees, exploring and documenting specialized structural issues of design, construction, and delivery. Mr. Griffis has developed particular expertise in the design of long span roof structures (stadiums, ballparks, arenas and convention centers), high-rise buildings, composite steel and concrete systems, and analysis of large buildings under wind and seismic forces. He is considered one of the top specialists in wind engineering in the US and author and contributor to the development of the ASCE 7 wind standard used by all US building codes. He has been a pioneer in the design of retractable roof stadiums and ballparks in the US, including Reliant Stadium and Minute Maid Park in Houston, Lucas Oil Stadium in Indianapolis and the Cardinals Stadium in Phoenix.

Projects completed under his direction have been honored with numerous structural awards, including the Eminent Conceptor Award, emblematic of the top engineering accomplishment in Texas, for eight different projects over the last fourteen years. In 1994, Mr. Griffis' career body of work in the development of composite steel systems was recognized by the American Institute of Steel Construction when he was named T.R. Higgins Lecturer. This prestigious award is the highest honor given by the steel industry in the United States. In 2002, Mr. Griffis was the recipient of the Civil and Architectural Engineering Outstanding Alumni Award at the University of Texas. A second honor bestowed on him during 2002 was the AISC Lifetime Achievement Award. This award honors individuals who have made an impact in the success of the structural steel industry. Additional professional honors include finalist as ENR Magazine's Construction Man of the Year, 1990. Mr. Griffis has directed numerous structural investigations of construction-related disputes and deficiencies.

Mr. Griffis was recently named to the National Academy of Engineering, the highest praise bestowed to an engineer by peers in the industry. He is one of only a few engineers to serve simultaneously on the code committees for both AISC and ACI and also as an on-going member of the ASCE 7 Standards Committee. He was recently named as a fellow to the American Concrete Institute (ACI). In 2009, Mr. Griffis received the coveted Kimbrough Award presented by the American Institute of Steel Construction as the highest award presented for design innovation in structural steel.
