Founded in 1966, SDL has provided the structural design and contract documents for many types of projects located throughout the United States and overseas.
SDL’s engineers are registered in 46 states (plus the District of Columbia, Puerto Rico and the US Virgin Islands) and consult with architectural firms, owners, and design-build contractors.
“It is our belief that possessing knowledge is a fundamental requirement, but it is the unique skill of putting the scientific knowledge to practical use that has made SDL a leader in creative structural designs since its inception in 1966.”
Dr. Stanley D. Lindsey
