Three new build teams arrive at their build sites and begin work on their cabins; Josh Tousignant makes the long trip to Cordova; John Donkersloot and Heather Rough oversee delivery of shipping containers; Chris Maynard flies out build materials.

Chris and Joe battle an 80-foot spruce, then a helicopter delivery almost goes wrong; John and Heather fall behind; Josh and his team must forklift their materials up the driveway to the build site after the semi gets stuck at the bottom.

Josh and his team install the second-story floor joists in their cabin; Chris runs out of lumber to build a dock, and the framers he hired don't show up; wrong cuts and measurements threaten to put John and Heather further behind than ever.

Chris and team prepare for two intense helicopter deliveries; Greg scales a raised rake wall to nail it into place; John and Heather's forklift threatens to knock over their frame; Josh and his team work from rickety ladders late into the night.

All three builds are running behind schedule; John and Heather build a water catchment system; Chris' windows are delivered by helicopter in a dilapidated crate that swings violently in the wind; Josh comes close to tipping over his forklift.

John and Heather try to figure out how to install drywall without covering their timber frame; Chris' windows spin violently during delivery; Joe and Duane install the metal roofing tin on a steep slope; bears eat Josh's onsite supplies.
