Step 1: Getting Started

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,        

Step 3: Post Rails

then cut your railing post  so it reaches the bottom of your girders and block it in from the edge and through bolt them lay out is 8' or what ever your choice. after all the railing posts are in and tight start the decking from the furthest spot (highest spot)

Step 4: Railing

now the railing  tricky must be no more than 4" apart    take some of your red wood boards up on edge  and mark every 4" two at a time make them exact  drill press your holes not all the way through the board though and cut the 1/2 " galvanized pipe into 32" pieces (think that's the number) and paint them.  youll be able to figure the length by the height you want your railing.

Step 5: Then Stain It and You Should Be Good.
