I managed projects and the trades’ quotes and scopes of work for a large home builder/renovation company, and two disaster restoration companies for 8 years. I am so glad to be out of those industries. It fucking sucks.

If I have one word of advice it’s this: holdbacks. Hold back 30% of payment until each trade has completed their deficiency list and cleaned up their work space. Otherwise you’ll never get them back for the next sub to start their scope of work, and your site will look like a pig sty.
