Plan a webinar

I work in marketing at a construction firm. Help me plan a client webinar.

Context: Facilities managers, developers and housing providers will give 45 minutes to a change in building standards or a lesson from a real project, explained by someone who delivers the work.

Before you start, ask me for anything missing from this list:
- The topic and the audience
- Who is speaking
- What we want attendees to do after

Then:
1. Write a title that states what people will learn.
2. Outline 30 minutes of content and 15 of questions.
3. Plan the invitation, reminders and follow-up.

Give me:
- Title and description
- A running order
- A promotion timeline

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:
- A slide saying the session is general information
- The technical content, checked close to the date by a qualified person
- How questions about a specific building will be handled
