NDT inspection cost in Seattle: Radiographic Testing rates
Field-anchored pricing guide for RT (Radiographic Testing) and the other five common NDT methods in Seattle, WA. Rates are quoted in USD per hour and reflect the Tier-1 labour band that applies across pacific northwest markets.
Boeing's NAS 410 compliance requires up-to-date Level II/III certification visibility for every contractor inspector on every shift — a gap shuts the work centre down.

Film or digital RT for new construction and in-service welds per ASME Section V and API 1104.
RT costs include source rental (Ir-192 or Co-60), film/DDA, processing, exclusion-zone setup, and radiation safety officer overhead. Night-shift premiums are common because exclusion zones can't coexist with other site work.
Seattle's industrial substrate — Aerospace (Boeing), Shipbuilding, Maritime — pulls NDT scopes onto recurring sites including Boeing Renton (737) and Boeing Everett (777, 767, 747). The local contractor pool prices against FAA Part 145 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 RT base band) accounts for local cost of living, procurement competition, and the documentary overhead that FAA Part 145 imposes. RT programmes in Seattle have historically clustered around the typical rate of $826 per hour, with turnaround and outage premiums pushing toward the high band.
Recurring industries pricing against this band:
Named operators / sites: Boeing Renton (737), Boeing Everett (777, 767, 747), Vigor Industrial Shipyard.
Crew rotation length
Multi-day mobilisations in Seattle 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. Aerospace (Boeing) sites in Seattle often require all three.
Shift premium
Night shift, weekend, and turnaround windows in Seattle typically carry a 25–40% premium on the base hourly rate.
Acceptance criteria
FAA Part 145 acceptance criteria require Level II / III sign-off, which prices above structural-weld AWS D1.1 work.
Equipment specification
Source licensing, exclusion-zone management, and night-shift premiums are the primary cost levers.
Programme volume
Multi-asset programmes at sites like Boeing Renton (737) typically negotiate volume discounts of 8–15% off the typical rate.
Mobilisation distance
Remote pacific northwest sites add a per-trip mobilisation charge ($350–$1,500 depending on travel distance from Seattle).
Documentation depth
Full digital scan packages with audit-grade traceability cost 10–20% more than basic written report deliverables, and are required at FAA Part 145 sites.
- 1.Plan RT scopes against the pacific northwest turnaround calendar to avoid rush premiums.
- 2.Batch multiple assets at the same site (e.g. Boeing Renton (737)) 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 RT 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.
- •Pipeline girth welds per API 1104
- •Pressure vessel welds per ASME Section VIII
- •Casting volumetric inspection
