In the 30+ rehabs I've done, I learned to start with the finished product in mind. I'd prepare drawings showing dimensions, locate outlets for example electric, water, and gas) drawn in, etc. Same for windows, doors, relocated walls, and so on.
BTW, they do not have to be done by an architect at this stage--your rough sketch should suffice.
I made copies of the drawings and highlighted each system. Example: if a ceiling light needed to be moved and/or installed, I'd highlight where it should go (with dimensions noted) and give that to the electrician.
It's best to go over each set of drawings while on-site with each contractor. Listen to what they suggest, and make sure to keep an open dialogue with them to make sure you are both on that same page. If it's a long-distance rehab, Facetime it.
Do this often enough and it will limit (not 100% eliminate) the chances of missing something. That's just the nature of the beast.
Good luck. Keep investing and moving forward!
