NDT inspection cost in Denver: Radiographic Testing rates
Field-anchored pricing guide for RT (Radiographic Testing) and the other five common NDT methods in Denver, CO. Rates are quoted in USD per hour and reflect the Tier-1 labour band that applies across mountain west markets.
Front Range NDT inspection windows are short — the high-altitude calibration interval drift on portable UT equipment has to be tracked tighter than coastal benchmarks.

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.
Denver's industrial substrate — Oil and gas (Niobrara Basin), Aerospace HQs, Manufacturing — pulls NDT scopes onto recurring sites including Suncor Commerce City Refinery and Lockheed Martin Denver. The local contractor pool prices against API 570 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 API 570 imposes. RT programmes in Denver have historically clustered around the typical rate of $826 per hour, with turnaround and outage premiums pushing toward the high band.

Named operators / sites: Suncor Commerce City Refinery, Lockheed Martin Denver.
Crew rotation length
Multi-day mobilisations in Denver 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. Oil and gas (Niobrara Basin) sites in Denver often require all three.
Shift premium
Night shift, weekend, and turnaround windows in Denver typically carry a 25–40% premium on the base hourly rate.
Acceptance criteria
API 570 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 Suncor Commerce City Refinery typically negotiate volume discounts of 8–15% off the typical rate.
Mobilisation distance
Remote mountain west sites add a per-trip mobilisation charge ($350–$1,500 depending on travel distance from Denver).
Documentation depth
Full digital scan packages with audit-grade traceability cost 10–20% more than basic written report deliverables, and are required at API 570 sites.
- 1.Plan RT scopes against the mountain west turnaround calendar to avoid rush premiums.
- 2.Batch multiple assets at the same site (e.g. Suncor Commerce City 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 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
