Who We Are
McMahan Engineering is a small, locally owned structural engineering firm based in Myrtle Beach, South Carolina. Founded by Jordan C. McMahan, PE, the firm began in 2023 while working nights and has grown into a full-time practice serving residential and smaller to mid-sized commercial projects across South Carolina and North Carolina.
Our Mission:
To deliver safe, thoughtful structural engineering that protects the people who live and work in the buildings we design, both today and for years to come, while treating every client with the care and responsiveness we would give our own family.
Our Approach:
Safety First
Every decision begins with protecting the people who will live, work, and gather in the structure.
Clear Communication
Calls are returned, questions are answered, and clients know what's happening with their project.
Direct Collaboration
We work alongside architects, contractors, owners, and building officials—not in a silo.
Engineering with the Long View
We design for more than permit approval. We want structures—and relationships—that last.
Every project is handled directly by a licensed Professional Engineer. No outsourcing. No layers of project managers. Just clear communication, careful design, and accountability from start to finish.
