Your Authoritative Resource for the Design and Construction of Concrete Segmental Bridges

A nonprofit organization to provide a forum where owners, designers, constructors, and suppliers can meet to further refine current design, construction and construction management procedures, and evolve new techniques that will advance the quality and use of concrete segmental bridges.

Gregg is joining ASBI after 31 years of service with the Bridge Division of the Texas Department of Transportation. He received a Bachelor’s Degree in Civil Engineering from Texas A&M University in 1986, joined the Bridge Division full-time as an Engineering Assistant, and received his license as a Professional Engineer in 1991. Gregg has held a number of positions within the Bridge Division and was appointed Division Director and State Bridge Engineer in October of 2011.

Gregg has been involved in the plan development and construction phase services for a number of segmental and signature bridges:

• He was the Design Group Leader for the Colorado River (Lake Marble Falls) Bridge on US 281 in Burnet County. The 958-foot-long twin segmental bridges are 40 feet wide each and used cast-in-place balanced cantilever segmental construction. Project cost was $19.4M and received a 2015 ASBI Bridge Award of Excellence.
• The Gulf Intracoastal Waterway Bridge on FM 2031 in Matagorda County in 2009 was another project for which Gregg led the plan development and construction engineering support. This 3,387-foot-long bridge is composed of a 690-foot (180’-320’-180’) balanced cantilever segmental bridge with 145-foot Type VI approach spans. This was the first segmental bridge designed by the TxDOT Bridge Division using AASHTO LRFD Bridge Design Specifications. The bridge was opened to traffic in June 2009 at a cost of $16M.
• Gregg served as the design project leader for the in-house design, plan preparation, and construction support for the world’s first precast concrete network arches on West 7th Street for the City of Fort Worth. This was an accelerated bridge construction project, with the roadway being closed for just six months during construction, and is composed of six spans, each 161 feet long. The project was completed in November of 2013 at a cost of $24M.
• More recently, as the Bridge Division Director, Gregg provided leadership during the early stages of the design-build project to replace the Corpus Christi Harbor Bridge on US 181. The new bridge will feature a 1,661-foot-long cable stayed main span. With a 205 feet waterway clearance, this six-lane facility will provide improved navigation clearance for the Port of Corpus Christi. This $809.2M project broke ground in 2017 and is expected to be completed in 2020.

Gregg has been involved in a number of professional organizations and committees throughout his career:

• From April 2013 to June 2015 Gregg served as a member of ASBI’s Executive Committee and on the Steering Committee for the 2014 Strategic Plan.
• He currently serves as the President of the Infrastructure Advancement Institute (IAI), a professional society he helped launch in 2014. Membership and attendance of the IAI Annual Summit has steadily grown to over 350 professionals. As co-founder and president, Gregg has been actively involved in membership growth, developing and implementing a strategic plan, creating a committee structure, and planning the Annual Summit which includes meeting logistics as well as technical program content.
• Since October 2011 Gregg has served as a member of AASHTO’s Subcommittee on Bridges and Structures (SCOBS) Technical Committee T-10, Concrete Design. He was appointed Committee Chair in May 2015 where he presided over the final 18 months of the effort to reorganize Section 5 of the AASHTO LRFD Bridge Design Specifications.
• In 2017, Gregg was appointed as a member of the Transportation Research Board Standing Committee on Concrete Bridges (AFF30).

Following confirmation of his selection as ASBI’s Executive Director, Gregg stated, “I welcome the opportunity to work with the ASBI Executive Committee and Board of Directors to continue ASBI’s rich history of promoting segmental bridges across the country as the best-value bridging solution. I look forward to guiding ASBI’s continued success as a recognized leader in the bridge building industry.”
