Well we had a decent weather forecast so I gambled that I could build the deck over my 4-day Thanksgiving weekend...
Planning and prep:
Borrowed the flatbed at work so I could store lumber out of the way and move into position when I was ready...
Pre-built the 20' main carrying beam in the garage. 3 layers of 2x10x10' (layed end to end) with layers of 1/2" PT plywood ripped to 9" and glued down the middle with PU construction adhesive (hopefully this will allow the 2x10s to shrink with out too much resistance).
This glue is crazy strong, and sets up very fast....

Had some company... one gaggle of 20 turkeys encountered a second gaggle of 13 turkeys and set about fighting for the turf outside my barn.
Execution:
Headers set in place and secured with Simpson ABU66Z and 5/8" x 5" concrete anchors x6
My piers are sitting on 20" x 20" x 8" footings, so I could have technically poured them 8" dia., but I oversized them to 12" dia. to give me some wiggle room, as I wasn't 100% confident of my layout.... good thing I did, as this one was off.
A buddy I play hockey with, who is a carpenter, came to work with me... 9 hours on Friday after TG, and a 10 hour push on Saturday. We had clear skies, and temps were "brisk" in the mid 30s.
Framed on Friday...
Decked on Saturday....
Finished up working solo on Sunday...
Threw a tarp over the whole thing and used the tractor forks to move the old junky pre-cast concrete steps back into position.... that restored access to the side (main) door to the house.
I'm pretty psyched that we beat the weather, as today I'm back at the day job and we have two days of snow in the forecast later this week.
