Deck framing details
Blocking between the i-beams to provide structural reinforcement and air sealing above the sill and below the floor decking.
Blocking boards pre-cut in quantity.
Blocking installed between the TGI i-beams.
Reinforced blocking around glulam support base.
3/4″ Avantech flooring glued and screwed in place.
Sealing the soffit under the deck
The deck extends over the edge of the foundation, overlapping the 10″ blocks of Neopor insulation that that will attach to the foundation wall below. 
The underside of the cantilever is sealed to make the shell of the house airtight.
The underside of each beam is glued with OSI SF-450 adhesive. The bead runs along the perimeter of the connection point. The screws go through in the middle to avoid breaking the bead seal. 
The two-by-four lumber under the soffit is an attachment point for the Neopor blocks of rigid foam insulation. The blocks will be notched out to fit. All gaps will be filled with spray foam insulation.

Building the deck
Work begins on the deck
Rain has caused delay, so work on the deck began immediately after the slab was poured.
Our first LVL beam in place.
The vertical metal straps cast into the foundation will attach to the future glue lam frame of the house.
Detail showing the sill sealer gasket between the sill plate and the foundation. Also, the LVL beam above is glued in place. From the beginning of construction all joints and connections are carefully glued and sealed air tight on the passive house.
Connection point on an i-beam glued and sealed in place.
At the end of the first day, 14″ LVL and PSL beams installed.
Pouring the slab
Rain has caused delay. The slab is poured at the first opportunity of clear weather.
4” of concrete poured on 10″ of EPS foam.
Dan Gregg brought in extra hands for the slab pour.

The rain returned at the end of the day.
Poking out from under
These five conduits extend under the footing and emerge in the utility room. Going under the footing avoids piercing the wall. This is where we will run TV, telephone and electrical service.
