are MEP engineers necessary?
We are building a around a 3000 sf/ft custom home and our architect is insisting on using an outside MEP engineer to design our systems. I'm not even exactly sure what a MEP engineer does. Pretty much everything I've found online mentions MEP for large commercial buildings. She said MEP services will be around $10,000 so we were wondering what our options are if we decide not to go with an MEP?
