Revit with EPDM

Hi all, i have a question

One user use revit architecture to design a building

One user use revit mep to design electrical items, piping...

The user user revit mep must import or link to use design file of revit arc user

How can we do it through EPDM?

If two or more users can edit one file at the same time it's very easy to work. How can enable it?

Thanks very much
