Procurement information
How California oil & gas work gets procured.
The common contracting vehicles for oil & gas engineering and construction in California. Match your scope, schedule, and risk profile to the vehicle before issuing an RFQ.
California agency RFP / RFQ
Public-sector oil & gas scopes are typically procured through California agency RFP or RFQ vehicles, with pre-qualification and SBE/DBE participation requirements.
Federal IDIQ vehicles
Federally funded oil & gas programs (DOE, DOT, USACE, EPA) are commonly executed under IDIQ contracts with task-order pricing on California sites.
Master Service Agreements
Operators in California engage engineering and EPC firms under multi-year MSAs covering capital, sustaining, and emergency response oil & gas scopes.
EPC and EPCM
Greenfield and major brownfield oil & gas projects in California are routinely delivered under lump-sum EPC or reimbursable EPCM contracts with a single integrated team.
Owner's engineer
Owners retain independent oil & gas P.E.s in California for design review, constructability, schedule and cost validation, and on-site representation through commissioning.
Direct P.E. engagement
Smaller California oil & gas scopes — feasibility, study, peer review, expert testimony — are engaged directly with a licensed P.E. on a time-and-materials or fixed-fee basis.
Typical fee range
$oil & gas engineering fees in California typically run 4–10% of TIC for greenfield work and 8–15% for brownfield/modernization scopes.
Lead time
Expect 2–6 weeks from RFQ to a signed engagement for well-scoped California oil & gas work; complex EPC awards typically run 8–16 weeks.
Compliance
California requires P.E. licensure on sealed deliverables; firms must hold a California Certificate of Authorization where applicable.

FAQ
Hiring a oil & gas engineer in California
How do I find a licensed oil & gas engineer in California?+
Search VectorCore for P.E.-licensed engineers practicing oil & gas work in California. Every record links back to the California board for live verification.
Do oil & gas engineers need a California P.E. license?+
Any engineering deliverable submitted to a California authority, regulator, or owner must be sealed by a P.E. licensed in California. Out-of-state engineers must obtain California licensure (often via comity) before sealing in-state work.
