Stanley D. Lindsey and Associates, Ltd. (SDL) is a full-service consulting structural engineering firm. 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, Saskatchewan and the US Virgin Islands) and consult with architectural firms, owners, and design-build contractors.
SDL has extensive experience in virtually every type of structure, including cultural, education, government, healthcare, hospitality, housing, industrial, laboratories, mixed use, office, parking, religious, retail, sports, and specialty structures. Design engineers have a minimum of a Master’s degree in Structural Engineering; Doctoral degrees are held by 4 of SDL’s engineers. 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.
Principals of the firm are production-oriented and actively involved in innovative design, research and analysis. Several members of the firm serve on national committees developing structural design codes and standards for the industry. The Construction Administration Department has registered Professional Engineers with a broad background in construction practices. The drafting department is well versed in Microstation, AutoCAD, and Revit.
SDL has been using Building Information Modeling (BIM) to create construction documents since 2006. SDL’s engineers and CAD technicians use the latest version of Autodesk Revit Structure in tandem to create and document models of new facilities. The models created include the main structural elements and miscellaneous structural elements that could contribute to conflicts with other trades. Having the structure modeled in BIM allows for conflict checks with other trades minimizing issues found during construction on a project. The firm is heavily involved in creating custom libraries to model various structural elements and has a complete Revit detail library for use on projects.
