A Century of Building Excellence
United Infrastructure Group, Inc. (UIG) is proud to celebrate 100 years of engineering innovation, construction excellence, and visionary leadership in the Southeastern United States. From humble beginnings in 1924 to becoming one of the region’s premier transportation-infrastructure firms, UIG has remained steadfast in its mission—delivering best-in-class road and bridge solutions while fostering a culture of integrity, innovation, and community.
UNITED INFRASTRUCTURE GROUP
our purpose
Foster growth and diversity in resources and disciplines by developing and motivating exceptional leaders in a Christian environment to achieve excellence by every standard of measure.
Humble Beginnings
Our story began when Frederick Amzi (F.A.) Triplett, alongside R.H. Small, founded Small & Triplett Construction Company. Their very first bridge project in Morristown, Tennessee, laid the groundwork for what would become a century-long legacy of infrastructure excellence. By 1926, they had completed a major milestone project in South Carolina—the SC 9 bridge over the Catawba River in Chester County—establishing the Triplett family name in the industry.
In 1934, F.A. Triplett took sole ownership, forming F.A. Triplett, Inc. Armed with only a seventh-grade education but a visionary spirit, he became a pioneer in bridge construction, shaping the industry until his passing in 1962.
A Family Legacy of Innovation
F.A.’s sons carried forward his mission with extraordinary ingenuity:
– Frederick (Fred) Triplett, Jr., a Clemson College graduate, was known for his engineering mastery and inventive approach. He designed overhead gantry cranes for bridge projects and even modified crane controls to help a disabled veteran continue working—earning him South Carolina’s “Employer of the Year” award in 1976.
– James Thomas (Tom) Triplett, also a Clemson alumnus, was a prolific inventor with over 30 patents spanning barges, cranes, trailers, and windmills. A true entrepreneur, Tom founded and consolidated multiple companies into United Contractors, Inc. in 1978—the direct predecessor of UIG.
Together, they laid the foundation for a culture of innovation, resilience, and service that continues to define UIG.
Best in Class: Building the Future
UIG’s core strength remains bridge and highway construction, but the company has continually evolved to meet the demands of an ever-changing industry.
– Diverse Capabilities: Demolition, culverts, fabrication, and engineering services allow UIG to control quality, timelines, and outcomes.
– Collaborative Partnerships: Strategic alliances with culturally aligned owner-operators enhance innovation and delivery.
– Kaizen Culture: A commitment to continuous improvement and training at every level ensures we remain “best in class.”
Our Christ-centered Purpose Statement reflects the heart of our culture:
“Foster growth and diversity in resources and disciplines by developing and motivating exceptional leaders in a Christian environment to achieve excellence by every standard of measure.”
This commitment to people, quality, and purpose remains the cornerstone of UIG’s success.
