About TRA

Blazed The Trail to Standards Achievement

When TRA began there were no industry-wide standards, no cohesive body of government regulations, and no one for manufacturers to turn to for help. T.R. Arnold & Associates, Inc. has been providing services to the Manufactured Shelter/Housing Industry since 1967.

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.
