Santa Ana engineering firm Salas O’Brien bought RMS Engineers in Richardson, Texas, on undisclosed terms. RMS does heavy industrial consulting in Texas for chemical; oil and gas; paper and pulp; and mining companies.

It’s the third acquisition this year for Salas; partners Darin Anderson, Chuck O’Neal, and Paul Silva have bought a dozen firms in as many years, pushing annual revenue to $145 million, including $11 million in OC billings.

Salas has hit the Inc. 5000 seven years running; Anderson won a Business Journal Excellence in Entrepreneurship nod in March.
