Terrapin Testing is a structural test laboratory, specializing in destructive testing of prefabricated building components since 1997.



Our sister company TJC and Associates, Inc. (TJCAA) recently formalized its long-standing, productive relationship with ICC-ES by becoming a member of the ICC-ES Partner Program, an honor reserved for only a handful of companies.  Our industry knowledge and our engineering and testing expertise give us the ability to guide our clients through an expedited product review process.

As an ICC-ES Partner, our initial project was in tandem with a solar racking manufacturer that we assisted and guided through the evaluation services report (ESR) product approval process. The result of this project was the first ESR for photovoltaic support systems. Along the way, we worked closely with engineers from both ICC-ES and the manufacturer to develop the acceptance criteria needed to recognize the photovoltaic racking systems. Then, once AC428 -Modular Framing Systems Used To Support Photovoltaic (PV) Modules was approved, we performed the testing, reporting, and quality assurance functions required to get an ESR issued.
