Quick answer
Fitness-for-Service Assessment covers assessing damaged or corroded equipment per API 579 to extend safe operating life. Done properly, it follows ASME Sec VIII Div 2, API 579, EN 13445 Annex B and produces fea model & mesh study that a fabricator or reviewer can use without rework. Structural Engineering Services delivers fitness-for-service assessment to clients in 40+ countries with a senior-engineer review on every package.
What drives the cost of fitness-for-service assessment
Pricing for fitness-for-service assessment is driven by five variables: scope size, complexity, code requirements, schedule and the quality of your input documents. Two projects that look similar on the surface can price very differently once those five are understood.
As a rule of thumb, an offshore delivery model like ours runs 40–60% below typical US, UK or Gulf local rates for the same code-compliant output — the saving comes from delivery location, not from cutting review steps.
Common pricing models
Reputable suppliers quote fitness-for-service assessment in one of four ways. The right model depends on how well-defined your scope is.
- Fixed lump-sum — best when inputs are complete; you get price certainty.
- Per-tonne or per-drawing — common for fabrication-linked work; scales with the package.
- Hourly / rate-based — best for evolving scopes and RFI-heavy phases.
- Frame agreement — a committed rate card for multi-year programmes, with priority scheduling.
How to budget accurately
The fastest route to an accurate budget is a real quote on your actual documents — generic online figures for fitness-for-service assessment are rarely useful because complexity varies so widely. Send your drawings and we return a fixed-price proposal within 24 hours.
When comparing quotes, normalise for scope: does the price include checker review, revisions, native files (ANSYS Mechanical Enterprise) and code compliance documentation? The cheapest headline number often excludes all four.
Hidden costs to watch for
Budget overruns in outsourced engineering usually come from rework, not rates. Watch for quotes that exclude revision cycles, charge extra for native-format files, or skip the independent check — the saving reappears later as fabrication errors and site delays.
