TSI ENGINEERING primarily operates under NAICS 238320 for painting and wall covering, 237990 for other heavy civil engineering, and 237310 for highway and bridge construction.

As a 2L entity based in North Highlands, California, TSI ENGINEERING operates as a small business without federal certifications. Their geographic presence supports West Coast federal projects, with a focus on DoD and DOT installations across California and potentially other Pacific-region bases.
