Role design and job descriptions for Concrete Block Makers: who owns the mix, the machine and the count
In a block yard the same few people mix, press, stack and load, and nobody can say whose job a weak or broken block was. A clear role sheet for each post ends that argument.

Without written roles, the batching operator, the block machine operator and the loading crew each assume the next person will catch a problem. A mix that is too dry reaches the pallet, the pallet reaches the curing yard, and the builder finds crumbling edges on site. Loaders are asked to count, stack and clean up, yet none of it is in their job, so counts are argued at the gate and breakage is blamed on whoever is standing there.
A good role sheet for a block plant is one page per post. It names the settings the machine operator controls, the check the quality checker does before pallets leave the machine, who signs the truck count, and who covers when someone is absent. Casual yard hands get a shorter sheet with the same headings, so a new loader knows on day one what a finished job looks like.
How to set it up
1. List every post in the yard
Walk the line from batching to the weighbridge and write each post on a card. Include casual loaders and curing attendants, as most of the daily argument sits with them.
2. Write what each post decides
For the block machine operator, note mix feed, vibration time and block height. For loaders, note count, stacking pattern and pallet condition. Keep each to five or six plain lines.
3. Name who signs and who covers
Pick one person to sign each truck slip and one backup for the machine. A role sheet with no named cover fails the first absent day.
4. Read it with the people who do the job
Sit with the operator and a senior loader and ask what is missing or wrong. They will find gaps in ten minutes that you would miss. See also role design and job descriptions.
5. Use it in hiring and briefing
Hand the sheet to every new yard hand and use it as the basis for the first week. Revise it once a quarter or when a machine or shift pattern changes.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Pick five truck slips from last week and see how many carry a named signer for the count.
- Ask your block machine operator which settings they own and compare with what you think they own.
- Count the posts in your yard that have no named backup.
- List the tasks loaders do today that no one has ever written down.

Questions owners ask
One page is enough. List the purpose of the post, the five or six things the person decides or checks, who they report to and who covers them. Long documents are not read on a yard, and short ones get used in the first week.
Yes, a short one. Casual hands change often, and a half page covering count, stacking, safety and who to report to saves repeat explanations. It also makes it clear who is responsible when a pallet is damaged.
Draft with the supervisor and the machine operator, then confirm as owner. People on the yard know where the gaps are, but only you can settle who signs the count and who covers when someone is absent.
