NDT inspection cost in Bath: Magnetic Particle Testing rates
Field-anchored pricing guide for MT (Magnetic Particle Testing) and the other five common NDT methods in Bath, ME. Rates are quoted in USD per hour and reflect the Tier-3 labour band that applies across northeast markets.
BIW destroyer construction packs NDT scopes into a tight Maine winter schedule — an out-of-cal UT unit during a pre-launch hull survey reshuffles the entire ship's delivery curve.

Surface and near-surface crack detection on ferromagnetic welds per ASTM E709 / E1444.
MT is one of the lower-cost methods because equipment is portable, consumables are inexpensive, and a single technician can cover a structural-weld scope quickly. Costs trend up with fluorescent (wet-mag) work that requires darkroom conditions.
Bath's industrial substrate — USN shipbuilding (destroyer construction), Heavy fabrication, Defense supply chain — pulls NDT scopes onto recurring sites including Bath Iron Works (General Dynamics) and Portsmouth Naval Shipyard (regional, Kittery). The local contractor pool prices against NAVSEA T9074 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-3 multiplier (×0.90 applied to the national MT base band) accounts for local cost of living, procurement competition, and the documentary overhead that NAVSEA T9074 imposes. MT programmes in Bath have historically clustered around the typical rate of $293 per hour, with turnaround and outage premiums pushing toward the high band.
Recurring industries pricing against this band:
Named operators / sites: Bath Iron Works (General Dynamics), Portsmouth Naval Shipyard (regional, Kittery).
Crew rotation length
Multi-day mobilisations in Bath 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. USN shipbuilding (destroyer construction) sites in Bath often require all three.
Shift premium
Night shift, weekend, and turnaround windows in Bath typically carry a 25–40% premium on the base hourly rate.
Acceptance criteria
NAVSEA T9074 acceptance criteria require Level II / III sign-off, which prices above structural-weld AWS D1.1 work.
Equipment specification
Dry vs wet mag, AC vs DC yoke, and shift premium are the main cost differentiators.
Programme volume
Multi-asset programmes at sites like Bath Iron Works (General Dynamics) typically negotiate volume discounts of 8–15% off the typical rate.
Mobilisation distance
Remote northeast sites add a per-trip mobilisation charge ($350–$1,500 depending on travel distance from Bath).
Documentation depth
Full digital scan packages with audit-grade traceability cost 10–20% more than basic written report deliverables, and are required at NAVSEA T9074 sites.
- 1.Plan MT scopes against the northeast turnaround calendar to avoid rush premiums.
- 2.Batch multiple assets at the same site (e.g. Bath Iron Works (General Dynamics)) 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 MT 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.
- •AWS D1.1 weld surface examination
- •In-service fatigue-crack screening
- •Forging and casting surface inspection
