Write an event recap

I work in marketing at a construction firm. Help me write up an event for people who missed it.

Context: A recap of a technical briefing or site visit gets read by people who were not there and may apply it to their own building.

Before you start, ask me for anything missing from this list:
- Notes or a transcript
- Who spoke
- What we can share publicly

Then:
1. Lead with the most useful thing said.
2. Cover three or four points, each with a plain explanation.
3. Link to the next event or a way to ask questions.

Give me:
- A recap of 300 to 400 words
- A LinkedIn post version

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:
- Technical points shortened until they mislead
- Photos from the event or site, checked for safe practice and consent
- A line that this is general information
