Build With OpenSpan Structural
OpenSpan Structural was built around one focused service: the structural work required to safely remove load-bearing walls and install the beams and supports that make open-concept renovations possible.
We work with homeowners, contractors, remodelers, and design-build teams throughout Southeastern Pennsylvania and Central New Jersey… providing clear scope, efficient execution, and professional engineering support where it matters most.
As we grow, we are also building a strong team and a trusted network of industry partners who share our commitment to doing structural work correctly.
Built Around a Clearly Defined Structural Scope
OpenSpan Structural is not a general remodeling company. Our role is intentionally focused: we handle the structural portion of load-bearing wall removal projects so the rest of the renovation can move forward with confidence.
That focus allows us to work efficiently, communicate clearly, and avoid the confusion that often happens when structural work is treated as just another demolition task. We evaluate the existing conditions, determine the beam and support solution, complete the structural installation, and coordinate the required structural inspection.
By specializing in this one part of the renovation process, we help keep projects organized, predictable, and ready for the next phase.

Focused Structural Expertise
We specialize in the structural work behind load-bearing wall removal, including beam installation, support planning, and structural inspection coordination.

Clear Scope from the Start
Our role is defined before work begins, so homeowners, contractors, and project teams understand exactly what we handle and what remains with other trades.

Efficient Project Handoff
Once the beam and supports are installed and approved, the project is ready for the next phase without confusion, overlap, or unnecessary delays.

Backed by Engineering Knowledge
Every project is approached with a structural mindset, helping ensure the solution is safe, buildable, code-conscious, and appropriate for the actual conditions of the home.

★★★★★ Rated 5 out of 5
It was a pleasure working with Patrick. He helped with a home purchase, where the general inspector identified some potential structural issues. His expert opinion confirmed the inspector's findings, and we'll communicate with the seller for a resolution, which could have been my financial burden without his report. The process was smooth and Patrick was quite thorough with his work. He delivered the report in ~2 days despite his recent hand surgery. Will recommend his work to anyone in the same situation.

We had the pleasure of working with Patrick during the process of purchasing our new home, and we couldn’t be more satisfied with the experience. Patrick was responsive, professional, and incredibly knowledgeable. Not only did he explain the foundation issues to us in great details, he also took the time to conduct a thorough inspection of the entire property to identify the root causes and gave us recommendations on necessary repairs to address the issues. His comprehensive report gave us the confidence to move forward with the purchase.
Aside from his expertise, he was willing to answer any questions we had and suggested licensed contractors that could do the work, which made the whole process less stressful. We felt supported and well-informed every step of the way.
Patrick truly went above and beyond, and we highly recommend Structure Professionals to anyone in search of a skilled structural engineer.

I highly recommend Patrick. He is professional, knows his stuff, and very compressive in his analysis of our foundation and water problems.
After speaking to him and his insight into our problems I trust him and am so glad I reached out to him before going with a corporate company. He offered several solutions and never did he push his own services after the analysis and he also offered the least expensive option first. This is best proscribes and ethical to the max. Thanks, Patrick!

We reached out to Patrick to review our recently purchased residential property. He was thorough and knowledgeable. It was easy to schedule an appointment, not to mention quick! The report was detailed and contained helpful and necessary information for the contractor. Definitely recommend!
I have worked with many structural engineers and there is nothing this company can’t figure out. The expertise Patrick Duffy and his team bring to the table are unmatched. Look no further if you need an honest assessment or the correct solution for your project. This company is the best in the industry- I can’t speak highly enough of them!
We had Patrick come and inspect our home due to a few concerns about the structure but also in preparation for our kitchen remodel. He was professional, very nice, and full of great advice! We would work with him again in the future and definitely recommend him to family and friends. Thanks Patrick!
I consulted Patrick at Structure Professionals while purchasing a home under contract to assess the structural integrity of a detached garage with foundation cracks and to determine the best way to attach a deck to the house. Patrick was incredibly knowledgeable, personable, and highly communicative. He provided a thorough evaluation of the garage, offering clear recommendations for necessary repairs, and explained the optimal deck attachment methods for long-term stability. His expertise and detailed explanations gave me confidence in my purchasing decision. I highly recommend Patrick for anyone needing a skilled structural engineer for home evaluations or construction guidance.
