Phase 2 of
Build
Steel I-Beams and columns are erected. 2” of
polystyrene is laid on top of 4” of gravel, which is atop a 6-mil
vapor barrier, rebar is installed and pex tubing (for in-floor
radiant heat) is attached to the rebar.
Carole is pointing to the pex tubing schematic, six zones will offer
control and efficiency. There will be approximately 7,200 linear
feet of pex tubing used throughout the home.
MORE CEMENT! Hey guys, please watch your step as you’re pouring
concrete over the pex tubing for the basement slab.
Bartley’s crew has been terrific – no pex tubing damaged - here
they’re doing finishing work on the basement slab.
Temporary bracing is constructed to support the first level flooring
system
Standing next to the first level flooring materials (Lite-Deck)is Greg Westra
and his crew from Mason-Dixon Technologies Inc. Greg is the
sub-contractor in charge of the building process thus far and has
been instrumental in educating us about ICF Construction. Lite-Deck
from Polysteel is a super-strong, super-insulated floor system,
which perfectly completes the thermal and structural envelope of our
Insulated Concrete Form project. It provides protection from severe
weather, fire and earthquakes, peace and quiet from inside to
outside and upstairs to downstairs, and superior energy efficiency
with nominal values of R-30+. With the added benefit of clear spans
up to 40 feet, it was the answer to our desire to have a Great Room with
no structural columns.
Lite – Deck is installed with block-outs for staircase, plumbing,
etc.
Rebar is installed over the Lite – Deck and again, pex tubing is
attached before Bartley’s crew begins another concrete pour.
Finishing work of concrete on first level.
Gabriel D’Silva's crew from Hand Master’s Inc. begin erecting
the entry level ICF walls. It's like putting Lego blocks together!
Here's Gabe himself cutting an ICF panel for the
front door opening.
We used STANDARD ICF™, www.standardicf.com, a high-efficiency
building system made of interlocking form blocks featuring molded
expanded polystyrene insulation. The STANDARD ICF™ forms a 7"
monolithic modified flat concrete wall and has an overall thickness
of 11 1/4", it’s total insulation blanket and the monolithic
concrete wall virtually eliminates air-infiltration and drafts in
above-grade structures.
This is VBUCK, a block-out system used in stay-in place insulating
concrete forms (ICF’s) for window and door openings, made from
extruded Poly Vinyl Chloride (PVC). The corner braces are removed
after the concrete is poured in the walls. Compared with wood (which
can warp, split, and twist) vinyl window block-outs effect energy
savings and makes installation of windows and doors a snap!
Additional rebar has been installed over window and door openings in
lieu of standard lintels. Bracing of ICF walls and scaffolding is
installed prior to pouring of concrete in the first floor walls.
