Quality Management System

CTLGroup laboratories has assembled one of the most demanding Quality Management Systems (QMS) for engineering consulting and testing of materials and structural components.

CTLGroup has assembled and maintains a robust Quality Management System (QMS) that enables us to consistently provide our clients with superior service and work product. Our dynamic QMS processes provide the framework for monitoring, measuring, and improving everything we do, ultimately translating to client satisfaction. Because of this, we have been able to attain AASHTO and ISO 17025 accreditations, ISO 9001 certification, U.S. Army Corps of Engineers validated lab status, and a QMS that meets the requirements of 10 CFR 50, Appendix B and NQA-1 (audited by NIAC).


All CTLGroup physical testing technician personnel are American Concrete Institute (ACI) certified at various levels.


CTLGroup participates in Cement and Concrete Reference Laboratory (CCRL) and AASHTO Materials Reference Laboratory (AMRL) Proficiency Sample Programs.
