Our Mission

We’re Committed to You

Regardless of the size and scope of your project, all building and vehicle designs are subject to compliance approval. Our engineers and plans examiners review your work during the building phase to verify that safety, accessibility and code compliance are achieved to maintain project schedules.

TRA is an approved Quality Assurance Agency (QAA) and In-Shop Monitor for manufactured structures in New York City. We are also approved to review manufactured structures using our licensed professional engineers for Colorado & Washington.


It’s critical to stay abreast of industry trends and standards. We pride ourselves on continuing education to demonstrate our commitment to your quality assurance needs.


We specialize in providing a full range of engineering services, tailored to the particular needs of the jurisdiction for each client.
