I use little stickie notes that are about 1"x2" and I tab the following
Job Duration
Liquidated Damages
If the insurance requirements are higher than average
Conduit type, uses, min sizes etc. If a specific conduit or MC is disallowed I'll highlight it in red highlighter
Any specific wire call outs ex: XHHW for 1/0 and greater
I'll also tab any suppliers that are specified for subs. Fire Alarm, Generator, AV etc.
Any mention of temp power in electrical specs will be tabbed.
I also write the important things on the front of the job folder. Other people in our office write in on a separate piece of paper and stick it in the job folder.
