NDT inspection cost in Los Angeles: Phased Array Ultrasonic Testing rates
Field-anchored pricing guide for PAUT (Phased Array Ultrasonic Testing) and the other five common NDT methods in Los Angeles, CA. Rates are quoted in USD per hour and reflect the Tier-1 labour band that applies across west coast markets.
South Bay aerospace primes audit subcontractor NDT files quarterly — a missing NAS 410 cert renewal disqualifies a vendor from the prime list for 12 months.

Encoded, imaged weld inspection per ISO 13588 and ASME Section V Mandatory Appendix.
PAUT carries a premium over conventional UT for equipment cost, procedure development, and Level II PAUT-credentialed technician availability. It often substitutes for RT — eliminating exclusion zones and night work — so on a per-weld basis it can come out cost-neutral or favourable.
Los Angeles's industrial substrate — Refining, Ports, Aerospace — pulls NDT scopes onto recurring sites including Marathon Los Angeles Refinery and Phillips 66 Wilmington. The local contractor pool prices against API 510 / 570 / 653 acceptance criteria, which requires Level II / III certified personnel and traceable instrument calibration. That floor — not raw wage data — is what sets the band.
The Tier-1 multiplier (×1.18 applied to the national PAUT base band) accounts for local cost of living, procurement competition, and the documentary overhead that API 510 / 570 / 653 imposes. PAUT programmes in Los Angeles have historically clustered around the typical rate of $856 per hour, with turnaround and outage premiums pushing toward the high band.
Recurring industries pricing against this band:
Named operators / sites: Marathon Los Angeles Refinery, Phillips 66 Wilmington, Port of Los Angeles, Northrop Grumman El Segundo.
Crew rotation length
Multi-day mobilisations in Los Angeles amortise travel and per-diem across more billable hours, lowering the per-hour rate. Single-day call-outs sit at the high band.
Access and rigging
Rope access, scaffold, or confined-space entry add 15–35% to the base rate. Refining sites in Los Angeles often require all three.
Shift premium
Night shift, weekend, and turnaround windows in Los Angeles typically carry a 25–40% premium on the base hourly rate.
Acceptance criteria
API 510 / 570 / 653 acceptance criteria require Level II / III sign-off, which prices above structural-weld AWS D1.1 work.
Equipment specification
Procedure development and PAUT-Level II tech availability drive cost. RT-substitution often nets cheaper at program level.
Programme volume
Multi-asset programmes at sites like Marathon Los Angeles Refinery typically negotiate volume discounts of 8–15% off the typical rate.
Mobilisation distance
Remote west coast sites add a per-trip mobilisation charge ($350–$1,500 depending on travel distance from Los Angeles).
Documentation depth
Full digital scan packages with audit-grade traceability cost 10–20% more than basic written report deliverables, and are required at API 510 / 570 / 653 sites.
- 1.Plan PAUT scopes against the west coast turnaround calendar to avoid rush premiums.
- 2.Batch multiple assets at the same site (e.g. Marathon Los Angeles Refinery) to amortise mobilisation across more billable hours.
- 3.Provide detailed component specs and accessibility info up-front — vague RFPs price high to absorb uncertainty.
- 4.Standardise on a single contractor for programme work; spot-buys carry a 10–20% premium.
- 5.Where PAUT is interchangeable with another method (RT ↔ PAUT, MT ↔ PT), price both before committing.
- 6.Verify Level II / III currency before quote — re-mobilisation for an expired cert is unbillable to the asset.
- •Code-case RT substitution on pipeline girth welds
- •Critical-weld inspection on heavy-wall vessels
- •Encoded corrosion mapping (C-scan)
