It might be obvious, but no one has explicity mentioned it. If you really wanted to build the monolith economy, but still gain maximum resources as soon as possible. Would you not build the normal economy first, say resource II's. But for the final two facility slots build a space yard for improved build and start the first monolith. As each monolith completes, scrap a normal facility and build another monolith. It is a lot a micromanagement, but it will get you the most resources along the way.
