"Although it looks new and different, anyone with construction experience can quickly get up to speed with ICFs... Once the crew has some practice, each ICF-built home requires less skilled labor and less total labor than a wood-framed home. And ICFs are very lightweight, so crews can stay fresh through the day.
"Likewise, ICFs present no problem for the sub-contractors who come after the
walls are poured. Since holes, chases and rectangles are easily cut into ICFs
with a knife or saw, installation of mechanical systems is a snap. The
fastening of drywall and lap siding is just as fast and easy. And mid-course
corrections, such as moving an opening, are no big deal - just saw it out and
re-form. It's not more difficult to make changes to an ICF wall - it's just
different."
