Paragon Structural Engineering, LTD. (PSE) is a premier structural design and forensic engineering firm located in Plano, TX.  PSE provides innovative structural engineering design solutions, as well as thorough forensic evaluations, for single-family residences, multi-family apartment/condominium complexes, low-rise commercial facilities, warehouses, and ancillary structures (retaining walls, screen walls, and swimming pools).  PSE’s unique position as a structural engineering design firm and a forensic investigation firm enhances PSE’s expertise and credibility through the symbiotic amalgamation of both fields.  PSE’s forensic investigation experiences allow the firm to continually improve its own design abilities since PSE’s engineers are able to implement lessons learned from investigations of existing structures to the designs of new structures.  Similarly, PSE’s structural design experiences enhance its credibility as forensic investigators since PSE’s engineers also have personal experience with the design of new structures similar to the ones being investigated.

“I have had the pleasure of collaborating with Paragon Engineering on several complex construction defect claims that required extensive forensic analysis. I have found their engineers to be independent and very professional. In my experience, most forensic engineers are able to analyze the source of the problem and write a report; where they fall short is in providing a practical solution in remediating that problem. In my line of work, finding the problem is the easy part. It’s the solution that the parties usually cannot agree on. When I call Paragon, I know I can count on them to find a solution that is practical and the parties and their experts can reasonably agree on. Thank you Paragon for helping us resolve our complex construction problems!”
