Is it normal for PMs to have tons of meetings without the design team?

I’ve been noticing a recurring issue lately and wanted to see if others in MEP consulting are experiencing the same thing.

It feels like a small group of PMs are having a large number of project meetings without including the actual design team (MEP engineers). Decisions, scope discussions, and owner expectations seem to get set in these meetings — and then the engineering team finds out afterward and has to react or redesign around decisions we weren’t part of.

For PMs and engineers out there:

Is this common at your firms?

Is this just a communication breakdown or a structural PM/design disconnect?

How do your teams handle keeping engineering involved without overloading calendars?

Curious how other MEP teams balance this.
