NDT inspection cost in Los Angeles: Ultrasonic Testing rates
Field-anchored pricing guide for UT (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.

Wall-thickness, weld and pressure-equipment inspection per ASME Section V and API 510/570/653.
Conventional UT (0.5–25 MHz contact or immersion) is the workhorse method on in-service pressure equipment. Costs scale with crew rotation length, instrument count, and access cost (rope access, scaffold, confined-space entry).
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 UT base band) accounts for local cost of living, procurement competition, and the documentary overhead that API 510 / 570 / 653 imposes. UT programmes in Los Angeles have historically clustered around the typical rate of $502 per hour, with turnaround and outage premiums pushing toward the high 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
Crew rotation and equipment count drive cost; couplant and consumables are negligible.
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 UT 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 UT 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.
- •Pipe and vessel wall-thickness surveys (API 570 / 510)
- •Weld inspection per ASME Section V
- •Storage tank shell and floor scanning (API 653)
