Bulla Smith Design Engineering (BSDE) is excited and proud to announce our merger with Stanley D. Lindsey and Associates, Ltd. (SDL), a structural engineering consulting firm with offices in Nashville, Tennessee and Atlanta, Georgia. SDL has over 50 years of innovative structural engineering experience and a portfolio of almost every project type. The union between BSDE and SDL will provide our clients with expanded resources, enhanced expertise, the ability to deliver additional services, and expand our market throughout the United States. Both firms share the philosophy of being responsive to the client’s needs and being a reliable and trusted partner – a tradition we are excited to continue.

BSDE was formed in 1999 by Tripp Bulla and Jeff Smith, after spending 29 combined years in private engineering practice. Both are registered professional engineers in North and South Carolina with Jeff’s expertise in civil engineering and Tripp’s expertise in structural engineering. Since being founded, BSDE has been providing civil and structural engineering services to the architectural communities of the Carolinas. Our project portfolio includes municipal, educational, institutional, governmental, environmental, military and commercial on the Local, State and Federal level. BSDE’s goal has always been to present our clients with innovative, effective and thorough engineering solutions as well as approach every project as an opportunity to learn and enhance our engineering. The result is that all of our projects benefit in terms of increased economy, efficiency and quality. For our existing clients, our relationships, philosophy, and quality of work will continue under the SDL family.
