Write a LinkedIn post from a client story

I work in marketing at a construction firm. Help me write a LinkedIn post from something that happened at work.

Context: The stories with pull come from site: a problem found behind a wall, a tight handover, an apprentice's first job. Most of them involve a client's building and a photo.

Before you start, ask me for anything missing from this list:
- What happened, in rough notes
- The point I want to make
- What I must leave out

Then:
1. Find the one idea.
2. Open with a specific moment or fact.
3. Keep paragraphs to one to three lines.
4. End on the point or one next step.

Give me:
- The post, 80 to 200 words
- An alternative first line

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Describe building work in general terms only. Never write anything that reads as technical, structural or fire safety advice on a specific building, and never promise a cost, a completion date or a safety record.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else the director who approves marketing or our health, safety and quality lead should see:
- Client permission to mention the project or show the building
- Photos checked for unsafe practice, missing PPE and identifiable people
- Anything that reads as blaming a designer, subcontractor or client
