1 Share of the bulldozer operator role’s weighted skill requirement already met by the tunnel boring machine operator 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 bulldozer operator role treats 9 of its required skills as things a tunnel boring machine operator already does. These are the ones it depends on most.

drive mobile heavy construction equipment
follow health and safety procedures in construction
keep heavy construction equipment in good condition
mechanical systems
prevent damage to utility infrastructure
react to events in time-critical environments

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

Skill the target role also needs Area

already held operate excavator working with machinery and specialised equipment
already held keep heavy construction equipment in good condition constructing
already held drive mobile heavy construction equipment working with machinery and specialised equipment
already held prevent damage to utility infrastructure management skills
already held mechanical systems engineering, manufacturing and construction
already held set up temporary construction site infrastructure constructing

All 14 carried skills, including the 9 the bulldozer operator role treats as required.

Table 3 · What you would need to learn

The 21 missing skills fall into 6 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.

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.
