How did Primoris Services rise from a regional contractor to an infrastructure leader?
Founded in 1960 in Bakersfield as ARB, Inc., Primoris Services evolved from a regional pipeline and maintenance specialist into a diversified infrastructure contractor by capturing North American energy-transition opportunities. Strong technical culture and safety focus enabled complex project wins and steady expansion.

What is Brief History of Primoris Services Company? Founded as ARB, Inc. in 1960 to serve West Coast oil and gas, it expanded through technical capability, safety leadership, and strategic acquisitions into a continental infrastructure player; see Primoris Services Porter's Five Forces Analysis.
What is the Primoris Services Founding Story?
Primoris Services Corporation traces its roots to 1960 with the incorporation of ARB, Inc. in Bakersfield, California, focused on heavy civil and mechanical work for the booming regional energy sector.
Founding Story
Founders leveraged mechanical expertise and bootstrapped capital to serve high‑pressure pipeline and facility construction needs, positioning the firm for steady regional growth.
- Founded in 1960 as ARB, Inc. in Bakersfield, CA
- Initial focus: high‑pressure pipeline systems and heavy mechanical/civil engineering
- Bootstrapped funding and reinvestment of profits to maintain lean operations
- Leadership, including Brian Pratt in later decades, guided expansion and diversification
The post‑war industrial expansion in the American West and escalating oil and gas development created demand for specialized contractors; ARB’s regulatory know‑how and equipment investments mitigated early volatility in energy prices and high capital costs.
Early years emphasized disciplined cash flow management and regional contracts, forming the basis of the Primoris Services Company history and setting a precedent for later acquisitions and business‑line evolution that appear on the Primoris company timeline.
