Plant and machine operators, and assemblers · code 8114

Cement, stone and other mineral products machine operators

AI can write the production log. Running the cement plant is still skilled, dusty work.

Keeping production records and checking plans are mostly out of AI's reach. It barely touches six of the ten tasks, including mixing concrete and cutting and polishing stone.

What they actually do (and what else they get called)

Cement, stone and other mineral products machine operators monitor and operate machines for manufacturing and finishing precast concrete, bitumen and stone products, and making cast stone for building purposes. Tasks include - (a) operating extrusion, moulding, mixing, pumping, compacting, grinding and cutting machinery to manufacture and finish precast concrete and stone products; (b) operating plant to produce cement, lime and clinker, including loading and unloading ingredients and operating continuous feed equipment such as pumps and conveyors; (c) operating plant and machines which weigh and mix sand, gravel, cement, water and other ingredients to make concrete; (d) operating plant and machinery which assemble and fill moulds with concrete and artificial stone mixtures, remove castings from moulds and finish surfaces of precast products; (e) cutting, grinding, drilling, sandblasting and polishing concrete products and stone blocks, slabs and products to the specifications for the job; (f) checking production plans and specifications to determine and select materials, ingredients, procedures, components, settings and adjustments for extrusion, moulding, mixing and compacting machines; (g) monitoring plant and machines during operation by observing instruments such as temperature and pressure gauges, adjusting controls and reporting malfunctions as necessary; (h) collecting and examining samples of mixtures and finished products for conformity with specifications and adjusting machine settings accordingly; (i) checking and maintaining production records, including information about quantities, dimensions and types of materials and goods produced; (j) arranging and assisting with plant and machinery maintenance and repair.

Mostly holds up against AI

AI can take a few chores off your plate, but most of the day is still yours.

Not the odds you keep your job. It's how much of the everyday work still needs a person, out of 100.

The ILO's official verdict: Not Exposed

177 of 427 for holding up against AI

Why this score?

The ILO rated each of this job's 10 tasks for how much of it AI could do. They average 22.6 out of 100, so it holds up at 100 − 22.6 = 77.4.

That's the whole sum. No black box, no secret sauce: you can check it against the ILO's study. ILO group “Not Exposed”: None of this job's tasks scored high enough to count.

Pinch of salt: this number is probably too rosy

It only asks what AI software could do, and this job is 71 out of 100 hands-on. A chatbot can't do that part. A robot might, one day, and nobody measures how close that is.

Meet your two rivals

They're not the same machine. AI software can only reach the parts of a job done on a screen or in words. A chatbot can't climb a ladder. A robot might, one day, if it doesn't fall off.

The AI

Lives in a screen. Never had to fix a boiler.

Threat level: Low

28 could do without you

It could take over very little of the work on its own. It could help with 58 of 100.

The robot

The wildcard. Has hands, still working out stairs.

How much it matters here: Higher

71 how hands-on

Most of this job needs hands, a body or turning up. That's robot territory, and nobody measures how far robots have got well enough to give you a number. We won't make one up.

So could a robot do the physical part?

More fine handwork, and more time in cramped or awkward spots, than a typical hands-on job. That is exactly what machines find hardest: they do best in tidy, predictable places.

Robots hate fiddly work in awkward spaces. On that measure, this job scores 45 out of 100. The higher it is, the longer the robot waits.

The small print

They aren't a robot score, and nothing on this page is. Nobody measures how far robots have got well enough to put a number on it. These are the closest thing we have: how hands-on the job is, and how much fiddly, cramped work it takes, which is what Frey and Osborne found hardest for machines.

The job, task by task

Every job is really a bundle of tasks. Here's this one unpacked, with how much of each AI could do, out of 100. The score is the average, and averages can hide a lot.

AI's favourite task here scores 50, against an average of 23. The bigger the gap, the more lopsided the job: some of it wide open to AI, some of it barely touched.

Sidekick or replacement?

A tool that makes you faster is a very different thing from one that does the task while you watch. Jobs and Skills Australia measured the two separately, which is handy.

So, should cement and concrete products operators be worried?

Short answer: not much. Some of the chores will change, and good riddance.

Parts of it are changing. Keeping records, checking plans, sampling products and monitoring gauges are the most exposed tasks, all Low; running mixers, moulds and kilns rates Very Low. Plant control keeps automating, so operators supervise and fix.

Worth remembering: we score tasks, not jobs. When AI takes on a task, the job usually reshuffles around it rather than vanishing.
