Once again I spent hours measuring & leveling; the laser level has proven itself to be invaluable.
To lift the beams up I used a technique I don’t know the name of but that I discovered watching this: link. This is no Stonehege but 3 2x8x16 with plywood sandwiched between is more than I can lift, this technique worked really well.
Leveling, mesuring, hammering for 9 hours. The 2 heaviest parts of the house, piers & beams are up a month ahead of schedule.
