Founded in 1988 as a structural engineering firm, TRC International Inc. (Nashville, Tennessee), built an excellent reputation with its customer-centric approach. It grew rapidly and diversified in response to its longstanding customers' need to access various services through a single window.

In late 1990s TRC made an ambitious plan to expand through both internal growth and strategic acquisitions. It founded TRC Worldwide engineering, Inc. in 1999 as the parent firm of its to-be-acquired subsidiaries. TRC Worldwide engineering, Inc. acquired Jenkins and Charland, Inc. and H. Wilden & Associates in 2000, and Suresh Patel & Associates in 2001.

Though these companies operated in different geographies and market segments they were bound together by a common commitment to secure customer interest through conscientious engineering.

To serve its customers better, TRC took advantage of globalization in the engineering industry by developing a strategic relationship with TRC Engineering (India) Private Limited. Since 1999 the two firms have worked together and built a global delivery process to bring value to clients through design innovation and service. To promote synergy between the subsidiaries, TRC management merged all subsidiaries with the parent firm in 2006.

Thanks to these initiatives TRC featured in the Engineering News Record's (ENR) list of Top 500 Design Firms of USA at 497th position in 2006. In the 2007 ranking it moved up to 422nd position. TRC continues to expand both through internal growth and acquisitions. Last year, it completed the acquisition of Doyle Engineering Group Dallas, TX, and Kracor, Inc., Phoenix, AZ. It also acquired 49% stake in ReStl Designers, Inc., Washington, D.C. In April, 2008, it acquired reputed MEP firm KM2 Design Group, P.C, Springfield, IL.

Along with TRCWW, its strategic partner TRC India, has also been expanding rapidly. Its Bangalore center has grown in size and competence. TRC India also expanded to Chennai in 2007, which is now set to move into a bigger facility with a 160+ seating capacity at DLF IT Park, situated in a special economic zone.
