1 Share of the tunnel boring machine operator role’s weighted skill requirement already met by the bridge inspector profile. Required skills count in full, supplementary skills at 0.35. Directional: the figure for the reverse move differs. 2 Combines what is missing with how specialised it is, so a gap of general skills scores easier than the same number of narrow ones.

Why

Why this move works

A tunnel boring machine operator role treats 5 of its required skills as things a bridge inspector already does. These are the ones it depends on most.

follow health and safety procedures in construction
mechanical systems
mechanics
use safety equipment in construction
work ergonomically

What stands in the way is 9 required skills the profile does not yet cover. Table 3 groups them; Table 4 says which to take first.

Table 2

Table 2 · What you already bring

Of the 6 skills that carry over, these are the ones fewest other occupations ask for. A tunnel boring machine operator role needs them, and most people applying for one will not have them already. This is the part of a bridge inspector background worth leading with.

Skill the target role also needs Area

already held mechanical systems engineering, manufacturing and construction
already held set up temporary construction site infrastructure constructing
already held use safety equipment in construction assisting and caring
already held follow health and safety procedures in construction assisting and caring
already held work ergonomically assisting and caring
already held mechanics engineering, manufacturing and construction

All 6 carried skills, including the 5 the tunnel boring machine operator role treats as required.

Table 3 · What you would need to learn

The 20 missing skills fall into 7 areas of the ESCO skill hierarchy, numbered below in the order worth working in: the areas carrying the most required skills come first, and inside each one the required skills sit above the supplementary ones.

3 gaps that are knowledge rather than practice

Knowledge gaps usually close through study. Practical skill gaps usually need something you can point at.

Note

How this record was compiled

Both occupations are taken from ESCO, which lists the skills and knowledge each occupation is expected to have and marks every one required or optional. Nothing here is a prediction about hiring, and nothing here knows that a particular employer wants a particular certificate. Treat Table 3 as a starting point for your own research rather than a syllabus. The full method states what these figures can and cannot tell you.
