First congratulations on starting your own business. I wish you best of luck. Owning your own business will be like a roller coaster ride and I hope you enjoy all of it.
Secondly let me applaud you by taking the high road and not copying what belongs to your ex-employer. This speaks highly of your character.
Many years back when i started my own business, I started a notes sheet as well. It has evolved so much over the years. My best advice is to break down the major heading of each notes and this is what I have on mine:
General Structural notes. I cover under this loads, codes, and general CYA type notes. This one is dynamic and changes with every project.
Structural steel notes. I cover steel grades, codes, welding, bolting, min. connection capacity, coating of steel, shop drawings requirement, welder certifications, etc.
Concrete notes. These cover concrete strength(s), bar grades, bar covers, splice length of rebars, I always add a note not use calcium chloride, standard hook length for various bar sizes, etc.
Masonry Notes. This covers masonry strength, bar grade, grout requirements, mortar type and strength, horizontal reinforcement, bond type, cold joint spacing, bar requirements at masonry openings, etc.
Timber notes (as required).
Light gage framing notes (as required).
Submittal requirements (I use state of Florida Board of engineer’s submittal requirements).
Abbreviations (this one keeps expanding).
I would read and review how others prepare their notes. Then you can tailor your accordingly. Vendors can be excellent source of notes as well.
The following are links to some sites that should give you an idea and start:
