ok it took me by my self nearly two days to lay out and square up the strings to mark my footings.   Once you get it all square dig the furthest corners first, set the sonotube hanging in the hole up off the bottom of the ground about 1 ft. so the concrete sluffs out as a footing then before it sets up push your simpson tie into concrete, level it make sure its still square with the rest.     then hang the girder from corner to corner then you can hang a string down from girder to mark the rest of your footings exactly.

Step 2: Joist's and paint

Ok the three girders are set and bolted down ,    now paint all of the joist's with a green wood preserver, if you want it to last.                  now lay out your joist's start from one end and block each joist on all three girders as you go nailing everything, this should be the fastes part , the most rewarding,

For maximum strength and durability, the posts and the railing posts should be one and the same

yes that's very true but in this case they were 4x6 and
I wanted more deck space. the posts have 4 through bolts in both directions they are sound.
Did you end up cutting off the uneven ends of the boards hanging over the right side?
